Abstract

The invention provides a three-dimensional reconstruction data processing method and device, electronic equipment and a storage medium. The method comprises the steps of acquiring first point cloud information, a first picture set, second point cloud information and a second picture set , wherein the first point cloud information is obtained during online reconstruction of a three-dimensional scene, the first picture set is a set of pictures used during online reconstruction of the three-dimensional scene, the second point cloud information is obtained during offline reconstruction of the three-dimensional scene, and the second picture set is a set of pictures used during offline reconstruction of the three-dimensional scene; determining K first target pictures in the first picture set andK second target pictures in the second picture set; determining first pose information corresponding to the first target pictures and second pose information corresponding to the second target pictures; and determining target transformation parameters of the first point cloud information and the second point cloud information according to the K pieces of first pose information and the K pieces ofsecond pose 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...
