The cameras and lenses we sell range from low cost point-and-shoot cameras with a fixed lens to high-end digital single lens reflex (DSLR) cameras with an interchangeable fish-eye lens.
When purchased from Regent Instruments, cameras and lenses come with a
calibration file that indicates to the WinSCANOPY program:
1) the position and radius of the 180 degree field of view hemispherical area to analyse in the image (hemisphere).
2) the calibration coefficients to compensate for non-linearities in the projection of elevation angle (azimuth) in function of distance to the hemisphere centre.
3) miscellaneous information about the camera (image size, aspect ratio…) and lens (model, FOV…).
You can also provide the calibration parameters of your own camera and lens. Note that this require some technical knowledge about these components and that Regent Instruments does not provide any help for this. |
