Equipment and method for realizing registration and fusion of multipath video images to three-dimensional digital earth system

Abstract

The invention discloses an equipment and a method for realizing registration and fusion of multipath video images to a three-dimensional digital earth system. The equipment comprises multiple video image acquisition devices respectively used for acquiring video images of one object from different angles to form multiple paths of video flows and decoding the multiple paths of video flows to acquire multiple video frames, a three-dimensional earth data acquisition device used for acquiring the three-dimensional scene information of all earth elements, the geographic space information and various types of attribute information of the earth object, a three-dimensional model construction device which is connected with the three-dimensional earth data acquisition device and is used for constructing and acquiring a three-dimensional geographic information scene model according to the three-dimensional scene information, the geographic space information and the various types of attribute information, a registration fusion device which is connected with the multiple video image acquisition devices and the three-dimensional model construction device, is used for realizing registration and fusion of multiple video frames to the three-dimensional geographic information scene model and is further used for displaying video images on the basis of the multiple video frames.

Description

technical field [0001] The invention relates to the technical field of image registration and fusion, in particular to a device and method for registration and fusion of multi-channel video images into a three-dimensional digital earth system. Background technique [0002] The technology of integrating multi-channel video registration into 3D digital earth provides a good way for people to quickly and intuitively understand multi-channel video images, and is widely used in video surveillance, digital earth simulation, remote control of digital earth and other fields . [0003] In terms of registration and fusion of 3D digital earth and real-time multi-channel video, the current technology is mainly in the simple integration of two-dimensional level by using component geographic information system. In this case, the real scene cannot be seen in the spatial position of the monitoring point displayed on the electronic map. That is to say, the current augmented reality system ...
