Example Embodiment

[0048] In order to make the objects, technical solutions, and advantages of the present invention, the present invention will be further detailed in connection with the accompanying drawings.

[0049] Please refer to figure 1 It is a schematic diagram showing the three-dimensional plane reconstruction system 1000 according to an embodiment. The three-dimensional plane reconstruction system 1000 includes a sensing device 100 and a computing device 200. The sensing device 100 includes a color camera 110, a depth camera 120, and azimuth sensor 130. Color camera 110 is, for example, a camera or a camera with a connecting function. Depth camera 120 is, for example, a two-camera, a structural light depth camera or a TIME OF FLight, a TOF depth sensor, or the like. The auguration sensor 130 can sense at least three axis rotation directions and three axis moving positions, such as consisting of one or more wide angle or fish-eye cameras and inertial measuring units (Inertial Measurement U...

Abstract

A method, a system, and a computing device for reconstructing three-dimensional planes are provided. The method includes the following steps: obtaining a series of color information, depth information and pose information of a dynamic scene by a sensing device; extracting a plurality of feature points according to the color information and the depth information, and marking part of the feature points as non-planar objects including dynamic objects and fragmentary objects; computing point cloud according to the unmarked feature points and the pose information, and instantly converting the point cloud to a three-dimensional mesh; and growing the three-dimensional mesh to fill vacancy corresponding to the non-planar objects according to the information of the three-dimensional mesh surrounding or adjacent to the non-planar objects.

Description

technical field [0001] The invention relates to a three-dimensional plane reconstruction method, a three-dimensional plane reconstruction system and a computing device. Background technique [0002] Generally, a mobile camera module scans the scene to establish a three-dimensional scene model. However, when scanning the scene, there are often people walking around, and the correct 3D scene model cannot be reconstructed. [0003] In many applications, only the planar structure in a 3D scene needs to be reconstructed, without including cluttered small objects or people. [0004] The amount of point cloud data generated by scanning the scene with the general method is very large, and it is necessary to obtain all the point clouds before converting them into meshes. This will occupy a large amount of memory and processor resources, and cannot be effectively applied to the headset. [0005] Therefore, researchers are devoting themselves to developing a new technology for scanni...
