基于单目视觉的车辆距离测量研究

Research on Vehicle Distance Measurement Based on Monocular Vision

提出一种单目测距算法,将车牌检测与距离测量分离,以车牌作为车牌检测和距离测量的纽带,使用YOLOv4-Tiny pro检测车牌,基于几何关系的车辆测距模型,根据车牌尺寸的先验信息准确计算出车辆距离。最后对系统的识别效果和距离检测结果分别进行了实验验证,对于整合后的算法进行了进一步优化,证明了方法的有效性。

The license plate detection was separated from the distance measurement,and the license plate was used as the link between the license plate detection and the distance measurement.YOLOv4-Tiny pro was used to detect the license plate,and the vehicle distance was calculated accurately based on the prior information of the license plate size.Finally,the recognition effect and distance detection results of the system are verified by experiments,and the integrated algorithm is further optimized to prove the effectiveness of the method.
