Abstract

We propose an improved Lucas-Kanade template tracking method with drift correction, which can be applied in rigid extended object. Due to error accumulation, primary template tracking method leads to template drift and loses object gradually. In order to alleviate template drift, SIFT (Scale Invariant Feature Transform) feature is used to correct the template drift. SIFT feature is invariant to scale, rotation even affine transformation, so, according to matching SIFT key-points between frames, the affine parameters of object transformation can be computed, then the current template position can be obtained by affine parameters and primary template position. The experiment results prove that the improved template tracking method based on SIFT drift correction can more accurately track the rigid extended object and can alleviate the tracking position drifting effectively.
