Obstacle detection device, robot and obstacle avoidance system

Abstract

The invention provides an obstacle detection device, a robot and an obstacle avoidance system. The obstacle detection device comprises a visual detector, an ultrasonic detector and an information fusion processor; the visual detector and the ultrasonic detector are connected with the information fusion processor; the visual detector acquires a front image, and transmits the image to the information fusion processor; the ultrasonic detector detects distance information of an obstacle, and transmits the distance information to the information fusion processor; and the information fusion processor determines obstacle information according to the received image and distance information, and outputs the obstacle information. According to the obstacle detection device, the robot and the obstacle avoidance system, the visual detector and the ultrasonic detector detect the obstacle information in the front simultaneously, thus all the obstacle information in the front can be detected accurately, and the situation of detection failure when in a night-vision environment or encountering obstacles such as a white wall and a fine rope is avoided.

Description

technical field [0001] The present invention relates to the technical field of obstacle detection, in particular to an obstacle detection device, a robot and an obstacle avoidance system. Background technique [0002] At present, robots and inspection vehicles have been widely used in the fields of industry and life. In order to prevent robots or inspection vehicles from colliding with walls or other obstacles in front of them when they are working, it is necessary to detect robots or inspection vehicles. When walking, whether there are obstacles ahead. [0003] In the prior art, most detection devices with a single information source are used for obstacle detection, for example, ultrasonic detection devices are used for obstacle detection, or cameras are used to collect images in front, and based on the collected images, it is analyzed whether there are obstacles in front, etc. Etc. However, using a single information source detection device for obstacle detection cannot a...
