Abstract

The present invention provides a data processing device, an electronic device and a storage medium for three-dimensional reconstruction. The method includes: acquiring first point cloud information, a first picture set, a second point cloud information and a second picture set, The first point cloud information is obtained when the 3D scene is reconstructed online, and the first set of pictures is a set of pictures used when the 3D scene is reconstructed online; the second point cloud information is obtained when the 3D scene is offline Obtained during reconstruction, the second set of pictures is a set of pictures used for offline reconstruction of the 3D scene; determine the K first target pictures in the first picture set and the K second target pictures in the second picture set The target picture; determine the first pose information corresponding to the first target picture, and the second pose information corresponding to the second target picture; according to K first pose information and K second pose information, Determine target transformation parameters of the first point cloud information and the second point cloud information.

Description

technical field [0001] The present invention relates to the field of three-dimensional reconstruction, in particular to a data processing method, device, electronic equipment and storage medium for three-dimensional reconstruction. Background technique [0002] 3D reconstruction technology has been widely studied in the fields of robotics, computer vision, and computer graphics, and is currently widely used in fields such as augmented reality (AR), virtual reality (VR), mobile robots, and autonomous driving. [0003] Due to the huge computational complexity of high-precision 3D reconstruction, it is difficult to complete online, but online 3D reconstruction has important practical significance in fields such as augmented reality and mobile robots. Therefore, in some existing technologies, low-precision reconstruction can be performed on the mobile terminal 3D reconstruction can be performed to obtain online reconstruction results to meet some needs (such as preview or naviga...
