Design And Implementation Of Moving Object Detection And Warn System Based On Vehicle Lens

Automobiles have become an indispensable means of transportation in our daily lives.With people's increasing attention to the hidden dangers of traffic safety,advanced driving assistance functions have also become an indispensable function of automobiles.The main work of this article is to design the detection and Warn system of moving objects around the body of the car in the stationary state and non-stationary state,using the vehicle-mounted fisheye lens,and the hardware platform centered on the Allwinner T707 car-level chip.The system was implemented and verified.Traditional moving object detection algorithms,such as frame difference method,background difference method,single Gaussian background modeling method,these algorithms can achieve good detection results for moving objects under static background,but the detection effect under dynamic background is very poor ideal.Although the optical flow method can detect moving objects under a dynamic background,the method requires a large amount of calculation,takes a long time,requires too much hardware platform,and it is difficult to meet the requirements of real-time detection,so the use of this method is limited Very big.After comprehensive evaluation of the above algorithms,this paper proposes a multi-model background motion compensation method based on single Gaussian background modeling.This method solves the detection interference caused by background motion well.By updating the background model through real-time compensation of the background motion,it is possible to simultaneously detect moving objects in a static background and a dynamic background.Finally,through the evaluation of the early Warn module,if it is possible to cause a traffic accident,it will remind the driver and passenger to make the correct operation in the form of an alarm.After a lot of experiments,the system implemented in this paper shows that the use of the system can greatly reduce the risk of traffic accidents when moving objects approach the car.
