摘要： Disclosed is a moving object detection apparatus and method by using optical flow analysis. The apparatus includes four modules of image capturing, image aligning, pixel matching, and moving object detection. Plural images are successively inputted under a camera. Based on neighboring images, frame relationship on the neighboring images is estimated. With the frame relationship, a set of warping parameter is further estimated. Based on the wrapping parameter, the background areas of the neighboring images are aligned to obtain an aligned previous image. After the alignment, a corresponding motion vector for each pixel on the neighboring images is traced. The location in the scene of the moving object can be correctly determined by analyzing all the information generated from the optical flow.
