A smart car reversing image and ultrasonic ranging system is designed in this paper. The system realizes real-time acquisition and display for video image through the camera, it transmits and shows obstacle distance information from ultrasonic ranging sensor. With STM32 microcomputer processing data, the performances of processing data rapidly and high precision are obtained. Using the device, obstacle image is displayed on the screen and a buzzer is designed to remind the driver the distance obstacles with different sound. The device can reduce the security risk and remind the driver of attention. [ABSTRACT FROM AUTHOR]
