基于ADAS的汽车倒车防碰撞系统设计与研究

Design and research of anti-collision system for car reverse based on ADAS

深入分析了当前倒车影像系统在实际使用场景上的不足,介绍了雷达存在的辐射面有限、角度盲区、物体识别方面的缺陷,以及毫米波雷达的高成本难以普及应用。提出了基于ADAS的汽车倒车防碰撞系统设计,对系统倒车功能做了深入的原理分析,针对基于倒车摄像头图像分析的ADAS算法详细介绍了其技术关键点和基于倒车场景融合特征的创新应用,算法识别效果精准有效。针对不同车辆摄像头安装位置和朝向的差异创新设计了灵活的预警和报警区域的调节功能,结合TTS语音提醒和图文显示提醒司机采取合适的操作保障行车安全,极大地改善了该倒车防碰撞系统的用户体验和实际作用,为司机的安全行车提供了有力保障。

This paper deeply analyzes the shortcomings of the current reversing image system in the actual use scene,introduces the limitations of radar in radiation surface,angle blind area and object type recognition,and the millimeter wave radar is difficult to popularize due to high cost.This paper puts forward the design of automobile reverse anti-collision system based on ADAS,makes an in-depth analysis of the principle of the system′s reverse function,and introduces the ADAS algorithm based on the image analysis of the reverse camera in detail its technical key points and the innovative application based on the fusion features of the reverse scene.The algorithm recognition effect is accurate and effective.According to the differences of the installation position and orientation of different vehicle cameras,the innovation design is carried out lexible early warning and alarm area adjustment function,combined with TTS voice reminder and graphic display to remind the driver to take appropriate operation to ensure driving safety,greatly improved the user experience and practical role of the reversing anti-collision system,and provided strong protection for the driver′s safe driving.
