Abstract
The present disclosure provides an optical flow tracking device. The device includes an image pyramid establishing circuit configured to establish a first image pyramid of a first image and a second image pyramid of a second image. The first image pyramid includes one or more image layers, and the second image pyramid includes one or more image layers. The device further includes an optical flow tracking circuit configured to perform an optical flow tracking processing on a kth image layer in the first image pyramid and a kth image layer in the second image pyramid to acquire an optical flow estimator of the second image in the kth image layer. K is an integer. The optical flow tracking circuit is configured to calculate an optical flow of the second image by using the optical flow estimator of the second image in the kth image layer.
