基于单个PTZ监控摄像机的道路全景建模与车辆检测跟踪方法
摘要：
本发明提供一种基于单个PTZ监控摄像机的道路全景建模与车辆检测跟踪方法，包括以下步骤：步骤S1，基于PTZ监控摄像机多视角图像构建道路全景图像背景模型；步骤S2，将输入的当前帧图像投影至全景图像背景模型；步骤S3，根据全景图像背景模型提取车辆前景区域；步骤S4，根据当前帧图像中车辆前景区域更新跟踪车辆目标状态；步骤S5，更新道路全景图像背景模型；步骤S6，根据车辆目标在当前帧图像中的位置向PTZ监控摄像机发出相应控制指令。本发明利用安装在道路路侧的单个PTZ监控摄像机通过上下/左右/放缩可以实现对整个道路场景进行监控，构建用于提取车辆目标的全景图像背景模型，实现对车辆目标的检测和跟踪。
摘要（英）：

The invention provides a road panorama modeling and vehicle detection tracking method based on a single PTZ surveillance camera. The method comprises the following steps of 1, constructing a road panorama image background model on the basis of multi-view images of the PTZ surveillance camera; 2, projecting an input current frame image to the panorama image background model; 3, extracting a vehicleforeground region according to the panorama image background model; 4, updating a state of a tracked vehicle target according to the vehicle foreground region in the current frame image; 5, updatingthe road panorama image background model; 6, sending a corresponding control instruction to the PTZ surveillance camera according to the position of the vehicle target in the current frame image. By means of the method, the whole road scene can be monitored through the vertical movement, horizontal movement and zoom-in and zoom-out of the single PTZ surveillance camera installed at the road side,the panorama image background model for extracting the vehicle target is constructed, and the vehicle target is detected and tracked.
