Target object matching method and device and target object monitoring system

The invention discloses a matching method and device according to a target object and a target object monitoring system. According to a target object matching method, based on a first camera device and a second camera device, a homography matrix between a first image and a second image is obtained by taking a calibration plane as a plane scene, and the target object can be matched on the first image and the second image by selecting one pixel point in the pixel range where the target object is located on the first image. According to the technical scheme, searching and matching of feature points in the image are not needed, and only one-time calibration is needed, so that the matching efficiency is improved. 本发明公开一种根据目标对象的匹配方法及装置、目标对象监控系统。根据目标对象的匹配方法，基于第一摄像设备和第二摄像设备分别以标定平面为平面场景拍摄得到第一图像与第二图像之间的单应性矩阵，通过在第一图像上选取目标对象所在像素范围内的一个像素点即可实现在第一图像和第二图像上对该目标对象进行匹配。本技术方案不需要在图像中进行特征点的搜寻和匹配，只需要进行一次标定即可，从而提升了匹配效率。
