I’m working on my master thesis and want to calibrate a camera with 194 deg fov, therefore i’m using the omnidirectional calibration method in opencv as i’ve understood that this is recommended for cameras with a fov >180 deg. While i was doing the robotic grasping research, i found out that template matching is a good approach for quick object localization but the template matching provided by opencv was not able to detect rotated and scaled in the match. also it will generate many redundant matching boxes which is useless for robotic grasping. therefore i made a few improvements on the original template matching.
