Regional safety protection system and method based on depth camera

Abstract

The invention discloses a regional safety protection system based on a depth camera. The regional safety protection system comprises acquisition equipment, an industrial personal computer and a controller, wherein the acquisition equipment is used for acquiring a depth image and a color image of a safety protection area and transmitting the depth image and the color image to the industrial personal computer; the industrial personal computer is connected with the acquisition equipment and the controller, and is used for receiving the depth image and the color image acquired by the acquisition equipment, detecting a human body, judging an intrusion relation between the human body and the safety protection area according to a detection result and sending different decision signals to the controller; and the controller is used for receiving and executing the decision signal so as to control the robot to work. The system can adapt to different bright environments, and is high in hardware integration level, flexible in installation position and high in precision.

Description

technical field [0001] The invention relates to the technical field of man-machine safety protection, in particular to a depth camera-based area safety protection system and method. Background technique [0002] With the development of industrial technology, industrial robots are widely used. In industrial production, human-machine collaboration is an important feature of the development of robots, and various types of robots and humans working together in industrial workshops have great potential safety hazards. [0003] At present, in order to solve the above hidden dangers, the existing industrial robots generally monitor the monitoring area by installing multiple 2D industrial cameras on the top of the machine, and combine the 3D reconstruction algorithm and the human body recognition algorithm to obtain the environment outline and the positioning of the human body, so that Realize three-dimensional monitoring. When the operator enters the monitoring area, the industria...

Problems solved by technology

However, there are some defects in this approach. Among them, the installation position of the 2D industrial camera is limited, and the effect can only be achieved if it is installed on the top, and multiple 2D cameras are required for 3D reconstruction. The accuracy of the depth direction is not high, and there are requirements for the ambient brightness. , can not be used in too dark and too bright environment
