| 摘 要： | 提出了一种适用于车载摄像机的前方车辆测距方法。建立感兴趣区域,利用帧间差分法初步提取图像,经过后续处理得到目标后,利用粒子滤波进行目标跟踪;通过交比不变性以及消失点的定义进行单目视觉测距并进行相关试验验证。

Distance Measuring of Preceding Vehicle Based on Monocular Camera |
| |
| Abstract: | An appropriate method about the distance measuring of the preceding vehicles with monocular camera in cars is proposed.Establishing the region of interest,using the frame difference to extract the image,through the follow-up method to obtain the object,then using the particle filter to track it;through the definition of cross ratio invariability and vanishing point to do the researches about distance measuring based on monocular camera and relevant experiments. |
