Multi-target tracking has important applications in many fields including logistics and transportation, security systems and assisted driving. With the development of science and technology, multi-target tracking has also become a research hotspot in the field of sports. In this study, a multi-attention module is added to compute the target feature information of different dimensions for the leakage problem of the traditional fifth-generation single-view detection algorithm. The study adopts two-stage target detection method to speed up the detection rate, and at the same time, recursive filtering is utilized to predict the position of the athlete in the next frame of the video. The results indicated that the improved fifth generation monovision detection algorithm possessed better results for target tracking of basketball players. The running time was reduced by 21.26% compared with the traditional fifth-generation monovision detection algorithm, and the average number of images that could be processed per second was 49. The accuracy rate was as high as 98.65%, and the average homing rate was 97.21%.During the tracking process of 60 frames of basketball sports video, the computational delay was always maintained within 40 ms. It can be demonstrated that by deeply optimizing the detection algorithm, the ability to identify and locate basketball players can be significantly improved, which provides a solid data support for the analysis of players’ behaviors and tactical layout in basketball games.
