To solve the problem of the optical flow algorithm being greatly affected by illumination and the highly variable detection effect in different scenes, in this paper, we propose an improved optical flow and Gaussian mixture model (IOFGMM) algorithm for the real-time detection of moving vehicles. First, a restriction is added to the optical flow algorithm whereby different constraints are used at different points. Then, a Gaussian mixture model (GMM) is fused. Finally, the number of target boxes and the area in which the target boxes overlap are compared by the proposed fusion algorithm. The vehicle detection information after fusion is displayed in the surveillance video. Experimental results show that the detection performance of the IOFGMM algorithm achieved an average accuracy rate of 84.80%, an average recall rate of 84.79%, and an average F1 value of 84.63% for videos of three different scenes. Compared with the classical optical flow method, the GMM, and the algorithm based on these two theories, the IOFGMM algorithm shows an average improvement of 37% in each metric. Therefore, we can conclude that the IOFGMM algorithm has good detection performance.
