Long-term visual tracking method for practical engineering application

The invention discloses a long-term visual tracking method for practical engineering application. Firstly, a tracking target is selected and a tracker is trained; different scale coefficients are reduced and amplified according to the tracking target frame; a series of sampling scale windows with different sizes are generated, then normal tracking is carried out on a tracking target in combinationwith the sampling scale windows, and when the tracking target leaves the view for a period of time and returns to the view with large scale and position changes, the tracking target can be effectively repositioned and continuously tracked, and accurate tracking is guaranteed. 本发明公开了一种面向实际工程应用的长期视觉跟踪方法，先选取跟踪目标并训练跟踪器，再根据跟踪目标框进行不同尺度系数的缩小和放大，生成一系列不同大小的采样尺度窗，然后结合采样尺度窗对跟踪目标实行正常跟踪，当跟踪目标离开视野后一段时间后，并以较大的尺度及位置变化回到视野时，能够有效的对跟踪目标进行重定位并继续跟踪，保证跟踪精确。
