    摘要： 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.

    摘要： The disclosure includes a 3-dimensional (3D) video communication method, a 3D video sending device, a 3D video communication system, an image reconstruction method, and an image reconstruction system. The method includes: obtaining timestamped video image data of a scene collected by image collecting apparatuses, where the video image data includes at least one depth image and at least two color images; and encoding the video image data and sending the encoded video image data. The system includes a sending device and a receiving device. The sending device obtains at least one depth image and at least two color images of the scene through the image collecting apparatuses, the obtained depth images are accurate and reliable, and the collection of the video images is highly real-time. When reconstructing the images at the viewpoints, the receiving device can repair the reconstructed images by using the obtained color images.
