Answer to Q1: You are not using map_1 and map_2 correctly.. The map generate by the cv2.fisheye.initUndistortRectifyMap function should be the mapping of the pixel location of the destination image to the pixel location of the source image, i.e. dst(x,y)=src(mapx(x,y),mapy(x,y)). see remap in OpenCV..
