An Early Warning System for Curved Road Based on OV7670 Image Acquisition and STM32.

Nowadays, the number of vehicles in China has increased significantly. The increase of the number of vehicles has also led to the increasingly complex traffic situation and the urgent safety measures in need. However, the existing early warning devices such as geomagnetic, ultrasonic and infrared detection have some shortcomings like difficult installation and maintenance. In addition, geomagnetic detection will damage the road surface, while ultrasonic and infrared detection will be greatly affected by the environment. Considering the shortcomings of the existing solutions, this paper puts forward a solution of early warning for vehicle turning meeting based on image acquisition and microcontrollers. This solution combines image acquisition and processing technology, which uses image sensor to perceive traffic condition and image data analysis algorithm to process perceived image, and then utilize LED display screen to issue an early warning.
