摘　　要：为了实现对目标人物的精准追踪,引进接力追踪技术,提出一种针对多摄像机目标人物的追踪方法。首先,引进多模态特征融合技术,辅助计算机技术的使用,提取目标人物跟踪特征。其次,引进接力追踪技术,在摄像头识别端导入目标人脸图片,在地图模块圈选初始追踪的点位进行追踪。最后,通过对目标的识别与预警,实现目标的现场级、无感知追踪。对比实验结果表明,在不同分辨率水平下,实验组追踪耗时均明显小于对照组,因此设计的目标人物追踪方法可以在实际应用中,可有效提高多摄像机目标任务的追踪效率。In order to achieve precise tracking of target characters,relay tracking technology is introduced to propose a tracking method for multi camera target characters.Multimodal feature fusion technology is introduced to assist in the use of computer technology to extract target character tracking features;Introduce relay tracking technology,import target facial images at the camera recognition end,and circle the initial tracking points in the map module for tracking.And through the identification and early warning of targets,on-site and perceptual tracking of targets can be achieved.Through comparative experiments,it has been proven that the tracking time of the experimental group is significantly shorter than that of the control group at different resolution levels.Therefore,the designed target person tracking method can effectively improve the tracking efficiency of multi camera target tasks in practical applications.
