AI Technical Summary

Technical Problem

When a mobile robot performs a cleaning task, it is difficult to accurately identify the relative position of obstacles and the robot, especially in the presence of obstacles with reflective, light-absorbing materials and complex shapes, which affects its environmental perception capabilities.

Method used

By collecting the laser image of the target area, extracting the candidate laser light strips, obtaining the theoretical position of the reference laser line in the laser image, screening out the effective laser light strips, and determining the position of the obstacle in the world coordinate system, combined with the inertial measurement unit and transformation The matrix performs position conversion to achieve accurate identification of obstacles.

Benefits of technology

It improves the accuracy of obstacle recognition, effectively solves the impact of reflection and refraction on laser images, and enhances the mobile robot's ability to perceive the environment, especially when identifying low and close obstacles.

Abstract

The present disclosure provides an obstacle recognition method, an apparatus, an electronic device, and a storage medium. The method comprises: collecting a laser image of a target area; extracting candidate laser bars in the laser image; obtaining the theoretical position of a reference laser line in the laser image; selecting valid laser bars from among the candidate laser bars on the basis of the theoretical position; and obtaining the position of an obstacle on the basis of the position of the valid laser bars in a world coordinate system.
