Detailed Description

Helper module to calibrate a given sensor+lens combo, which allows ArUco and other modules to do 3D pose estimation.

Just follow the on-screen prompts to calibrate your camera. The calibration results will be saved into /jevois[pro]/share/camera/ on microSD and will be automatically loaded when using a machine vision module that uses camera calibration, for example DemoArUco or FirstVision.

The basic workflow is:

• print a calibration board and affix is to a good planar surface (e.g., an acrylic board, aluminum board, etc). Or buy a board, for example from https://calib.io or similar.
• decide which sensor, resolution, and lens you want to calibrate. The sensor should be detected at boot time (check engine::camerasens system parameter). The lens can be set manually through the engine::cameralens parameter. The default lens is called "standard". For the resolution, edit videomappings.cfg and add a mode for the CalibrateCamera module that will use the same resolution as the one you want to use later for machine vision. Several commented-out examples are already in videomappings.cfg, so likely you can just uncomment one of them. Then run the corresponding version of the CalibrateCamera module.
• set the parameters to match the board type, board width and height in number of tiles, tile size in the unit that you want to later use to estimate distance to detected objects (e.g., in millimeters, inches, etc), and possibly ChArUco marker size and dictionary.
• point the camera towards the board so that the full board is in the camera view. Click 'grab'. Change the viewpoint and repeat at least 5 times. Use various 3D viewpoints.
• click 'calibrate' and the calibration will be computed and saved to microSD for that sensor, resolution, and lens. It will be ready to be loaded by modules that want to use it.

The default settings are for a 11x7 Chess Board that was created using the online generator at https://calib.io and which you can get from http://jevois.org/data/calib.io_checker_260x200_7x11_23.pdf - When you print the board, make sure you print at 100% scale. You should confirm that the checks in the printout are 23mm x 23mm.

An alternate chess board with fewer checks may be desirable at low resolutions, such as the 7x5 chess board at http://jevois.org/data/calib.io_checker_260x200_5x7_36.pdf - if you use it, set board size to '7 5', and square size to '36' to match it.

If you are using a wide-angle fish-eye lens with a lot of distortion, turn on the fishEye parameter.

You can also use a ChArUco board, though we have actually obtained worse reprojection errors with these boards. You can print the board at http://jevois.org/data/calib.io_charuco_260x200_5x7_36_27_DICT_4X4.pdf at 100% scale, and you should confirm that the checks in the printout are 36mm x 36mm, and the ArUco patterns within the white checks are 27mm x 27mm. If you use it, you need to set the board type, size, marker size, and square size parameters to match it. An alternate board with more ChArUcos is at http://jevois.org/data/calib.io_charuco_260x200_7x11_23_17_DICT_4X4.pdf
