Builds the projection maps according to the given camera data

[xmap,ymap,bbox] = obj.buildMaps(src_size, K, R)

Input

• src_size Source image size [w,h].
• K Camera intrinsic parameters, 3x3 single matrix.
• R Camera rotation matrix, 3x3 single matrix.

Output

• xmap Projection map for the x-axis, single matrix.
• ymap Projection map for the y-axis, single matrix.
• bbox Projected image minimum bounding box `[x,y,w,h].
