Embodiment 1

[0033] Attached below figure 1 The present invention is further described, a SLAM autonomous navigation and identification method in a closed scene, comprising the following steps:

[0034] Step 1: Obtaining external environment data, the autonomous robot obtains external environment data through its own camera;

[0035] Step 2: Feature detection, input the acquired external environment data into the SLAM feature extraction module, and the SLAM feature extraction module uses the Vision transformer model to realize the semantic detection of each object in the external environment, and extract the features of each object at the same time;

[0036] Step 3: Data association, the SLAM data association module tracks the common features of images in different frames, and achieves the same feature matching through the correlation clustering between frames, and then judges the movement of the object; for the successfully matched features , the controller of the autonomous robot correc...

Embodiment 2

[0060] The difference between this embodiment and Embodiment 1 is that the cluster value k=100 is set.

Abstract

The invention belongs to the technical field of image processing, and particularly relates to an SLAM autonomous navigation identification method in a closed scene, an SLAM data association module in data association of the method tracks common features of images in different frames, the same feature matching is realized through correlation clustering between the frames, and the SLAM autonomous navigation identification method in the closed scene is realized. The moving condition of the autonomous robot is judged; compared with the prior art, the method has the advantages that (1) compared with a data association method in the existing SLAM (Simultaneous Localization and Mapping), the clustering matching has higher practicability, and the clustering matching effect is not influenced by various complex scenes; and (2) the K-means clustering algorithm is simple in calculation, can be embedded into various systems for feature matching, and is very suitable for visual SLAM in a dynamic environment.

Description

technical field [0001] The invention belongs to the technical field of image processing, and in particular relates to a SLAM autonomous navigation and identification method in a closed scene. Background technique [0002] Simultaneous Localization and Mapping (SLAM) refers to the use of visual sensors mounted on the robot to perceive the surrounding environment without prior information, establish an environment model during the movement process, and estimate the location of the robot itself. technology. [0003] Current visual SLAM methods are usually based on the static assumption, that is, objects in the default environment are in a static state during the entire visual SLAM process. However, most of the practical application environments are dynamic environments, and there are dynamic objects, such as walking people, driving cars, etc. These dynamic objects affect the accuracy of mapping. SUMMARY OF THE INVENTION [0004] Aiming at the above-mentioned problem that th...
