Problems solved by technology

This method has the following disadvantages: on the one hand, the analysis process in the connected domain of this patent is complicated, which is not conducive to real-time registration; on the other hand, the method only performs binary segmentation on the image, which is easily affected by noise, and the segmentation accuracy is not high , so the registration accuracy cannot be guaranteed

Embodiment Construction

[0040] The technical solution will be described in detail below through a preferred embodiment and in conjunction with the accompanying drawings.

[0041] Such as figure 1 As shown, this embodiment provides a real-time dynamic registration method suitable for RGBD-SLAM and a machine-readable storage medium storing instructions of the method, including image preprocessing and image registration:

[0042] (1) Image preprocessing

[0043] RGBD-SLAM calculates the orientation of the camera in an unknown environment through the captured video information, and constructs an environmental map at the same time. Since the grayscale and gradient information of heterogeneous images are significantly different, and the contrast is different, in order to achieve dynamic registration in real-time video information, the color image and infrared image must first be processed to obtain an edge information image with superior effect for matching . That is to detect the edge information of t...

Abstract

The invention discloses a real-time dynamic registration method suitable for RGBD-SLAM and a machine readable storage medium. On the basis of the SLAM of the depth camera, edges are extracted by applying phase consistency according to each frame of infrared image and color image provided by the TOF and the camera, then normalization cross-correlation is calculated by adopting a blocking strategy,an optimal matching pair is obtained, and the offset is calculated, so that accurate registration of the infrared image and the color image is realized. According to the invention, real-time registration can be realized, the registration result is accurate, the operation of the SLAM can be guided more correctly, better AR experience can be brought to a user, and the life of people is more convenient.

Description

technical field [0001] The invention relates to an image processing method of SLAM, in particular to a real-time dynamic registration method and a machine-readable storage medium suitable for RGBD-SLAM. Background technique [0002] SLAM (simultaneous localization and mapping, simultaneous positioning and map construction) originated in the field of robotics. Its goal is to reconstruct the three-dimensional structure of the environment in real time in an unknown environment and simultaneously position the robot itself. As the core technology of autonomous robots, SLAM has important research significance in robot navigation, control, production and other aspects. Especially in the 21st century, visual SLAM technology centered on visual sensors has undergone significant changes and breakthroughs in theory and methods, and is gradually moving from laboratory research to mature market applications. Early SFM (Structure from Motion) technology was generally processed offline. La...
