This program is shipped with the USGSCSM library in the bin directory.
It can perform several operations involving CSM camera models, such as:
- Load a camera model, whether in the original ISD format, model state representation, or GXP .sup file
- Export the camera as a model state file
- Compute projections from pixels in the camera to the ground and back, and measure the discrepancy with the original pixels.
Example (load a camera model and save the model state):
usgscsm_cam_test --model input.json --output-model-state out_state.json
Example (perform per-pixel operations):
usgscsm_cam_test --model camera.json --sample-rate 100 \ --height-above-datum 320.3 --subpixel-offset 0.57
Example (modify a GXP .sup with new model state):
usgscsm_cam_test --model camera.json --modify-sup-file gxp_file.sup
| --model <string (default: "")> | |
| Input CSM model (in ISD, model state, or GXP .sup file format). | |
| --output-model-state <string (default: "")> | |
| If specified, save the model state to this file. | |
| --sample-rate <integer (default: 0)> | |
| If positive, select pixels in the camera at the intersection of every one out of this many rows and columns, and perform projections to the ground and back. | |
| --subpixel-offset <double (default: 0.0)> | |
| Add this value to every pixel row and column to be sampled. | |
| --height-above-datum <double (default: 0.0)> | |
| Let the ground be obtained from the datum for this camera by adding to its radii this value (the units are meters). | |
| --desired-precision <double (default: 0.001)> | |
| Use this value for operations (ground-to-image and image-to-ground) which need a precision value. Measured in pixels. | |
| --modify-sup-file <string (default: "")> | |
| Input GXP .sup file to be modified by inputted CSM model. This will override the existing .sup file's SENSOR_STATE. | |
| --help <no value> | |
| Print the usage message. | |
