基于HALCON的移动车辆检测方法研究

Research on Moving Vehicle Detection Method Based on HALCON

为了实现移动车辆的快速准确识别,基于HALCON软件提出一种移动车辆自动识别方法,根据帧差法原理将视频序列中当前帧图像分别与相邻前、后两帧作差,再将差值作"与"运算,通过设定分割阈值检测出移动的目标,最后结合目标区域几何特征筛选出移动车辆。实验结果表明,这种方法检测正确率高,且适用于多个移动目标检测场景。

In order to identify the moving vehicles fast and accurately, proposes a method of identification of moving vehicle based on HALCON. Ac- cording to the principle of frame difference method, makes the difference between the current frame image with both previous frame image and next frame image, uses the ＂and＂ operation on these two differences, then detects the moving target by setting the segmentation threshold, and the moving vehicle can be found by the geometrical features of target area. The experiment results show that the proposed method has high detection accuracy, and suitable for multiple moving targets detection scene.
