-This program's purpose is to collect data sets of an object and its segmentation mask.
-
-It shows how to use a calibrated camera together with a calibration pattern to
-compute the homography of the plane the calibration pattern is on. It also shows grabCut
-segmentation etc.

-select3dobj -w <board_width> -h <board_height> [-s <square_size>]
- -i <camera_intrinsics_filename> -o <output_prefix> [video_filename/cameraId]
-
- -w <board_width> Number of chessboard corners wide
- -h <board_height> Number of chessboard corners width
- [-s <square_size>] Optional measure of chessboard squares in meters
- -i <camera_intrinsics_filename> Camera matrix .yml file from calibration.cpp
- -o <output_prefix> Prefix the output segmentation images with this
- [video_filename/cameraId] If present, read from that video file or that ID
-
-Using a camera's intrinsics (from calibrating a camera -- see calibration.cpp) and an
-image of the object sitting on a planar surface with a calibration pattern of
-(board_width x board_height) on the surface, we draw a 3D box aroung the object. From
-then on, we can move a camera and as long as it sees the chessboard calibration pattern,
-it will store a mask of where the object is. We get succesive images using <output_prefix>
-of the segmentation mask containing the object. This makes creating training sets easy.
-It is best of the chessboard is odd x even in dimensions to avoid amiguous poses.
-
-The actions one can use while the program is running are:
-
- Select object as 3D box with the mouse.
- First draw one line on the plane to outline the projection of that object on the plane
- Then extend that line into a box to encompass the projection of that object onto the plane
- The use the mouse again to extend the box upwards from the plane to encase the object.
- Then use the following commands
- ESC - Reset the selection
- SPACE - Skip the frame; move to the next frame (not in video mode)
- ENTER - Confirm the selection. Grab next object in video mode.
- q - Exit the program
