Embodiments of the present invention provide a method and a device for multi-camera image correction. The method for multi-camera image correction includes: acquiring information of independent images that are captured by each camera and have no overlap area or have an overlap area smaller than a threshold; acquiring, according to information of each independent image, an image correction parameter that corresponds to each camera and allows adjacent independent images to be corrected into a contiguous image; and performing, according to the image correction parameter, correction processing on video data of a camera that corresponds to the image correction parameter. In the embodiments of the present invention, maintenance manpower is saved, adjustment efficiency is improved, and remote maintenance may be performed in the case of no overlap area or of a small overlap area. In addition, images are corrected in a data processing manner, which efficiently ensures precision of image correction.

Method and device for multi-camera image correction

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.
