Object following car based on template matching

Object tracking technology has always been one of the hot topics in the field of computer vision, its research and development can better improve people's life, and object tracking based on the car platform is an important embodiment of this technology. This paper describes the object tracking car which is composed of OpenCV video image processing module and STM32F407 car platform, using the template matching algorithm of OpenCV function library, and through image preprocessing and frame difference method with template update to match, to achieve the car following the object under a certain video frame rate. It involves mask processing, binary processing, normalized processing and expansion corrosion processing in image processing. After integrated processing by Powersensor, serial port data is sent to cooperate with STM32 microcontroller to control the car movement, so as to complete the locking of objects and tracking of the car.
