Problems solved by technology

[0005] Although the first type of method is simple, it requires special marking points on the surface of the rigid body, which is inconvenient in many cases, and this method cannot bring a very natural user experience.
The second type of method has a wider scope of application than the first type of method, but it requires pre-acquisition of multiple images of the target rigid body in the video and the use of third-party software to reconstruct the target rigid body offline, which makes it relatively difficult for users to use cumbersome and inflexible

Abstract

The invention provides an online three-dimensional reconstructing and locating method for rigid body. Based on the combination of the image segmentation and the synchronous map construction and location technology, the method segments the moving rigid body in the video from the image so that the synchronous map construction and location can be applied to the rigid body. With the adoption of the method, the reconstruction and location process of the rigid body can be carried out completely online and automatically after initialization.

Description

technical field [0001] The invention belongs to the field of three-dimensional reconstruction and positioning of a rigid body, in particular to a method for online three-dimensional reconstruction and positioning of a rigid body. Background technique [0002] It is a core technology in applications such as augmented reality, robot visual servoing and vision-based human-computer interaction to give the position and attitude of the target rigid body relative to the camera in real time in the video. The main methods currently used can be divided into two categories: [0003] The first type is based on the reference point method, which requires some easily identifiable marking points on the surface of the target rigid body and the three-dimensional positions of these points in the rigid body coordinate system are known. At runtime, these markers are first found from the video image. Then use the corresponding relationship between the three-dimensional position of these points ...
