Obstacle evading method and device of intelligent robot

Abstract

The invention provides an obstacle evading method and device of an intelligent robot. The intelligent robot is provided with multiple ultrasonic sensors and at least two depth cameras. The method comprises the steps that when a target object is detected by both the depth cameras and the ultrasonic sensors, the depth image information of the target object is determined; according to the depth image information, the distance from the target object to the intelligent robot is calculated; and the intelligent robot is controlled based on the distance to evade the target object in the walking process. Accordingly, the depth cameras and the ultrasonic sensors can be combined for detecting the obstacle, and the accurate and effective obstacle evading effect can be achieved.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to an obstacle avoidance method and device for an intelligent robot. Background technique [0002] With the rapid development of science and technology, smart terminal devices are more and more widely used in all walks of life and people's lives, such as smart phones, PADs, smart robots, and so on. Taking intelligent robots as an example, intelligent robots can be applied in agriculture, medicine, aerospace, military and other fields to liberate a large part of the labor force, bring more convenience to people and create greater social value. [0003] During the use of an intelligent robot, various obstacles may be encountered in its walking state. How to avoid obstacles (also referred to as obstacle avoidance) has gradually become a research hotspot in this field. At present, in the obstacle avoidance scheme of intelligent robots, for example, ultrasonic waves can be used to det...

AI Technical Summary

Problems solved by technology

At present, in the obstacle avoidance scheme of intelligent robots, for example, ultrasonic waves can be used to detect obstacles. Triggered, causing the robot to act incorrectly; on the other hand, the ultrasonic measurement of the distance of the obstacle requires the reflection of the obstacle. If the obstacle is too small or flat, there is not enough area to reflect the ultrasonic wave, that is, the obstacle cannot be detected , cannot achieve effective obstacle avoidance

For another example, binocular vision obstacle avoidance can be used, such as using a binocular camera. There is a visual blind area so that obstacles cannot be detected; on the other hand, when the lighting conditions are insufficient, the imaging effect of the camera is not good, and the position and size of obstacles may not be reflected, so that effective obstacle avoidance cannot be achieved.
