摘要
针对复杂背景下车辆跟踪的难点,提出一种新的跟踪算法来更好地实现复杂背景下的车辆跟踪。该算法融合MeanShift和Kalman两种跟踪方法各自的优点,即在MeanShift跟踪过程中插入Kalman预测车辆下一步的运动位置。首先,通过设置好Kalman滤波功能选择的阈值,对MeanShift的跟踪结果进行判断,若MeanShift跟踪结果理想,则Kalman滤波的功能是平滑跟踪结果;若跟踪结果不理想,则Kalman滤波的功能是预测下一帧车辆的位置。最终试验结果说明该算法能有效提升跟踪精度和鲁棒性,实时性提高了17%左右,车辆丢失率降低了20%～30%左右,能更好地针对复杂背景下完成对车辆的跟踪。
Aiming at the difficulties of vehicle tracking in complex background,a new tracking algorithm is proposed to better realize the vehicle tracking in complex background.The algorithm combines the advantages of MeanShift combined Kalman＇s two tracking methods.That is,during the MeanShift tracking process,insert the Kalman to predict the next movement of the vehicle.In our method,we combined the MeanShift and Kalman tracking methods.That meant Kalman filter was added to the vehicle during the MeanShift process to predict the vehicle.First,the tracking results of MeanShift are judged by setting the threshold selected by the Kalman filter function.If the MeanShift tracking results are ideal,then the Kalman filter function is smooth tracking results,otherwise Kalman filter function is to predict the next frame of the vehicle position.The results of the final experiments showed the real-time increased by about 17%,so this method can effectively improve the tracking accuracy and robustness.And the vehicle loss rate decreased by 20% to 30%.It can be better for the complex background to complete the tracking of the vehicle.
