Abstract:
Disclosed is an object detection method used to detect an object in an image pair corresponding to a current frame. The image pair includes an original image of the current frame and a disparity map of the same current frame. The original image of the current frame includes at least one of a grayscale image and a color image of the current frame. The object detection method comprises steps of obtaining a first detection object detected in the disparity map of the current frame; acquiring an original detection object detected in the original image of the current frame; correcting, based on the original detection object, the first detection object so as to obtain a second detection object; and outputting the second detection object.

Abstract:
The present invention relates to a method and a system for rectifying images. An original stereo image pair is obtained, and the epipolar lines corresponding to the original stereo image pair are parallelized to obtain a first transformed stereo image pair. Epipolar lines corresponding to the first transformed stereo image pair are collinearized to obtain a second transformed stereo image pair. The present invention parallelizes and collinearizes the epipolar lines corresponding to the stereo image pair after the images are rectified.
Abstract:
A heterogeneous network includes a terminal side and a network side. The network side includes an original PoA and handover candidate PoAs. The terminal side is used to select the handover candidate PoAs, initiate a media independent handover request, terminate a connection with the original PoA, and establish a connection with the handover candidate PoAs. The original PoA is used to terminate the connection with the terminal side according to the media independent handover request initiated by the terminal side. The handover candidate PoAs is used to establish the connection with the terminal side according to the media independent handover request initiated by the terminal side. A method for handover between heterogeneous networks initiated by the terminal side and the network side based on the 802.21 architecture is also provided, which improves the processing of the handover process.
