Title:
USGS CoastCam CACO-02 at Marconi Beach, Cape Cod National Seashore, Massachusetts (2021, 2023, 2024): Calibration Data
Abstract:
Two digital video cameras were installed at Marconi Beach, Cape Cod National Seashore (CACO) in Massachusetts (MA) as part of a U.S. Geological Survey (USGS) research project to study the beach and nearshore environment. The cameras faced north/north-east (c1) and north-east/east (c2) along the beach and collected images for 17 minutes at 2Hz every half hour during daylight hours. They ran daily from March through June 2021, February through July 2023 and January through September 2024; the cameras collected raw images and produced snapshots and time-averaged image products. This data release includes the necessary intrinsic orientation (IO) and extrinsic orientation (EO) calibration data to utilize imagery to make quantitative measurements. USGS researchers analyzed the imagery collected from this camera to remotely sense a range of information including shoreline position, sandbar migration, wave run-up on the beach, alongshore currents, and nearshore bathymetry. These cameras are part of the USGS CoastCam network, supported by the Total Water Level/Coastal Change Project under the Coastal and Marine Hazards and Resources Program (CMHRP).

Supplemental_Information:
The bounding coordinates below represent the approximate limits of the rectified images from the CoastCam. The cameras were initially positioned to maintain approximately 7.5m of cliff toe overlap in their field of view (FOV). The intrinsic calibration photos were taken on 20210225 for the 2021 and 2023 deployments and on 20240105 for the 2024 deployment and their location information is not consequential. For each deployment (2021, 2023, and 2024), the cameras were positioned pointing roughly north-east (c1) and east (c2), however each deployment should be considered separately with regards to extrinsic calibration. IO/EO information is provided in the image EXIF headers as calculated from Bruder and Brodie (2020), however we recommend to the user to calculate their own EO data based on the dates of the imagery used. Please see CACO02_calibration_metadata for necessary IO/EO information. Throughout the course of the deployment the cameras can move due to changes in temperature, wind, or other factors.

    Entity_and_Attribute_Overview:
    There are a total of 60 for camera 1 and 165 for camera 2 IO JPEG images from 20210225 (CACO02_c1_20210225_IO and CACO02_c2_20210225_IO) and 51 for camera 1 and 71 for camera 2 IO JPEG images from 20240105 (CACO02_c1_20240105_IO and CACO02_c2_20240105_IO). The filename for each IO image is formatted as "CACO02_c#_YYYYMMDD_IO_####.jpg", where CACO02 describes the location, c# is the specific camera, YYYYMMDD is the date of the calibration, IO is for intrinsics orientation and the number (####) is the photo ID. There are 4 sets of EO images for each camera (CACO02_c2_20210310_EO, CACO02_c1_20210317_EO, CACO02_c1_20230322_EO, CACO02_c2_20230322_EO, CACO02_c1_20240105_EO, CACO02_c2_20240105_EO, CACO02_c1_20240612_EO, CACO02_c2_20240612_EO). All IO and EO images have EXIF and other imagery header information encoded within each file, see the process steps for more information. To place the photos taken by the CoastCam into real world coordinates and to rectify them into a planar view, objects within the FOV of the camera must be located. The elevation and position of the lenses in the CoastCam setup were estimated by surveying the top of each camera housing with an RTK GPS (approximately 9cm above the camera center). The CoastCam took pictures of the position of each target within the camera view. The 'CACO02_c2_20210310_EO', 'CACO02_c1_20210317_EO', 'CACO02_c1_20230322_EO', 'CACO02_c2_20230322_EO', 'CACO02_c1_20240105_EO', 'CACO02_c2_20240105_EO', 'CACO02_c1_20240612_EO', 'CACO02_c2_20240612_EO' folders contain the GCP CSV files, the resultant EO parameters in a human-readable YAML file, and 'raw' and 'annotated' images showing all the GCPs. The CSV files (CACO02_c2_20210310_EO_GCPsurvey.csv, CACO02_c1_20210317_EO_GCPsurvey.csv, CACO02_c1_20230322_EO_GCPsurvey.csv, CACO02_c2_20230322_EO_GCPsurvey.csv, CACO02_c1_20240105_EO_GCPsurvey.csv, CACO02_c2_20240105_EO_GCPsurvey.csv, CACO02_c1_20240612_EO_GCPsurvey.csv, CACO02_c2_20240612_EO_GCPsurvey.csv) with all the measurements were populated and GCP numbers were hand labeled on the annotated images (CACO02_c2_20210310_GCP_image_annotated.jpg, CACO02_c1_20210317_GCP_image_annotated.jpg, CACO02_c1_20230322_GCP_image_annotated.jpg, CACO02_c2_20230322_GCP_image_annotated.jpg, CACO02_c1_20240105_GCP_image_annotated.jpg, CACO02_c2_20240105_GCP_image_annotated.jpg, CACO02_c1_20240612_GCP_image_annotated.jpg, CACO02_c2_20240612_GCP_image_annotated.jpg) so that the targets could be labeled correctly in Step B of the Camera Calibration steps in Bruder and Brodie (2020). A complete list of image names and original datetime are provided in CACO02_calibration.csv.

Why was the data set created?

Data were obtained to document interannual changes in shoreline position and coastal morphology. These data (81,613 Joint Photographic Experts Group RGB images) are intended for science researchers, students, policy makers, and the public. These data can be further processed to produce orthorectified products that can be viewed in a geographic information system (GIS) or other software to identify topographic and shallow-water bathymetric features. See the image processing toolbox developed by Bruder and Brodie (2020) for more information.

    The CoastCam cameras were used to take IO photos. Images were initially saved as .tiff files and converted to .jpg. The IO process involved moving a printed checkerboard with 2.8-centimeter (cm) squares to various parts of the camera's FOV and obtaining images from the stationary camera. Camera 1 had 60 IO images on 20210225, and camera 2 had 165 IO images on 20210225. A subset were used for the intrinsic calibration (MATLAB Camera Calibrator), however all are provided for completeness. The images are available on the USGS Imagery Data System here: https://doi.org/10.5066/P13UW5LB. These were used in step A in the Camera Calibration procedures outlined in Bruder and Brodie (2020) by A.M.Z. Lange. The resultant parameters are stored in a YAML file located in the respective folders CACO02_c#_YYYYMMDD_IO, where c# is either c1 or c2 for the camera number, and YYYYMMDD is the date the IO images were obtained. Image file naming format follows CACO02_c#_YYYYMMDD_IO_####.jpg, where c# is the camera name, YYYYMMDD is the day the IO images were obtained, and #### is the image number out of the available images for the IO calibration process.

    EO calibration GCPs were collected on 20210310, 20210317, 20230322, 20240105 and 20240612. To place the photos taken by the CoastCam into real world coordinates and to rectify them into a planar view, objects within the FOV of the camera must be located. To do so, the elevation and position of the camera lenses in the CoastCam setup were measured with the RTK GPS. Then, multiple stationary targets were spread through the camera FOV to be used as GCPs, and the location of each was measured with the RTK GPS equipment. The GCPs consisted of large square targets, divided into quadrants and colored white and black, and were either made of fabric and laid flat on the ground (center point on ground was surveyed) or made of wood and propped up to face the CoastCam (bottom-center, between black and white at ground level, was surveyed). When all GCPs were in place, a snapshot was taken with the camera. On 20210317, multiple images (3 for c1) and on 20230322 (2 for c1 and 3 for c2y) were taken with the GCPs moving between images to provide more surveyed targets (CACO02_c1_20210317_GCP#_image_raw.jpg, CACO02_c1_20230322_GCP#_image_raw.jpg, CACO02_c2_20230322_GCP#_image_raw.jpg). The targets from images 2 (and 3) were cropped and superimposed on image 1 to create an image with all GCPs (CACO02_c1_20210317_GCP_image_raw.jpg, CACO02_c1_20230322_GCP_image_raw.jpg, CACO02_c2_20230322_GCP_image_raw.jpg). The image coordinates of the targets on the combined image are the same as in the original images. The survey locations of the GCPs in the CSV file were used to hand label the raw image to generate an annotated image (CACO02_c2_20210310_GCP_image_annotated.jpg, CACO02_c1_20210317_GCP_image_annotated.jpg, CACO02_c1_20230322_GCP_image_annotated.jpg, CACO02_c2_20230322_GCP_image_annotated.jpg, CACO02_c1_20240105_GCP_image_annotated.jpg, CACO02_c2_20240105_GCP_image_annotated.jpg, CACO02_c1_20240612_GCP_image_annotated.jpg and CACO02_c2_20240612_GCP_image_annotated.jpg) so that the targets could be labeled correctly in Step B of the Camera Calibration steps in Bruder and Brodie (2020). The pixel coordinates of each GCP within the raw image (hand-selected), solved in Step B of Bruder and Brodie (2020), the GPS positions from the CSV file, and the IO parameters in the IO YAML file were used in Step C of the Camera Calibration steps in Bruder and Brodie (2020) to solve for the EO parameters. The resultant parameters for the EO calibration are stored in a YAML file located in CACO02_c2_20210310_EO.yaml, CACO02_c1_20210317_EO.yaml, CACO02_c1_20230322_EO.yaml and CACO02_c2_20230322_EO.yaml, CACO02_c1_20240105_EO.yaml, CACO02_c2_20240105_EO.yaml, CACO02_c1_20240612_EO.yaml and CACO02_c2_20240612_EO.yaml.

How reliable are the data; what problems remain in the data set?

  1. How well have the observations been checked?
    EO calibration ground control points (GCPs) were computed from surveyed data points during Field Activities 2021-019-FA, 2021-022-FA, 2023-006-FA and 2024-002-FA. Calibration success can be examined using the CIRN Quantitative Coastal Imaging Toolbox (Bruder and Brodie, 2020) where parameters azimuth, tilt, and roll have errors less than 2 degrees. Accuracy of the extrinsic calibration was also tied to the human ability to locate targets in the imagery. The camera systems were liable to move over time via wind, wear, and human interactions cleaning the camera, all of which may change the camera calibration parameters. Calibration data is stored in YAML Ain't Markup Language (YAML) files named with the calibration date.
  2. How accurate are the geographic locations?
    Real-Time Kinematic (RTK) Global Positioning System (GPS) equipment with decimeter horizontal accuracy was used to survey GCPs within the camera FOV and used to validate the extrinsic camera calibration. The GCPs have a theoretical accuracy of 1-2 cm. The precise locations of the targets were used in the CIRN Quantitative Coastal Imaging Toolbox steps B and C (Bruder and Brodie, 2020). Horizontal coordinates were referenced to the North American Datum of 1983 (National Spatial Reference System 2011) Universal Transverse Mercator Zone 19 North (NAD83(2011)/UTM Zone 19N) coordinate system (Epoch 2010.00). The camera pole was located at 41 deg 53' 33.44" N, 69 deg 57' 47.50" W EPSG:6318 NAD83 (2011).
  3. How accurate are the heights or depths?
    RTK GPS equipment was used to survey GCPs within the camera FOV and used to validate the extrinsic camera calibration. The GCPs have a theoretical accuracy of 1-2 cm. The precise locations of the targets were used in the CIRN Quantitative Coastal Imaging Toolbox steps B and C (Bruder and Brodie, 2020). Vertical positions were referenced to the North American Vertical Datum of 1988 (NAVD88) with GEOID18 coordinate system.
  4. Where are the gaps in the data? What is missing?
    Used calibration images and surveyed GCPs are provided. Camera extrinsics were calibrated four times for each camera during its operation.
  5. How consistent are the relationships among the observations, including topology?
    The camera system installed (FLIR Blackfly S) had an extrinsic and intrinsic calibration process. The EO calibration process was completed on 20210310 (for c2), 20210317 (for c1), 20230322, 20240105 and 20240612 and consists of a YAML file of resultant EO parameters, a comma-separated values (CSV) file of GCP locations and description, and Joint Photographic Experts Group (JPEG) images, one labeled as 'raw' and the other as 'annotated', respectively, showing the 5 (for c2 on 20210310), the 12 (for c1 on 20210317), the 5/8 (for c1/c2 on 20230322), the 7/9 (for c1/c2 on 20240105) and 6/6 (for c1/c2 on 20240612) GCP targets that were surveyed. The IO calibration process was completed on 20210225 for the 2021 and 2023 deployments and on 20240105 for the 2024 deployments. They consist of 60 and 165 JPEG images for 20210225 and 51 and 71 JPEG images for 20240105 for c1 and c2 respectively, of a checkerboard pattern that collectively covered the entire image frame, used with the Camera Calibration App (MATLAB) to solve for the intrinsic parameters and lens distortion, which are provided in a YAML file of resultant IO parameters. Significant figures are taken as provided by the app. A 28mm square checkerboard pattern (7 x 9 squares) was used and the lens distortion was solved for 3 radial coefficients and 2 tangential coefficients. These are used in the CIRN toolbox steps A through C to be able to georectify imagery and make quantifiable measurements.
