Problems solved by technology

[0003] Point-type gas detection lasers are often used for safety detection in industrial production, but they cannot feed back visual images, nor can they provide real-time information on the specific location of the leak in the monitoring area, and cannot provide effective help for guiding production rescue
Usually, the staff carry a point-type gas detection laser to manually scan the tightness and stability of the machinery, gas tanks, and pipelines in the production area. It is difficult to ensure full-scale scanning and monitoring of the production area.

Abstract

The present application provides a method for generating a two-dimensional laser point cloud image based on laser scanning, including, based on the set two-dimensional position matrix, controlling the pan-tilt to move point by point to drive the laser detector and visible light installed on the pan-tilt The imager moves synchronously; at each point of the two-dimensional position lattice, the concentration value of the detected gas on the surface of the object to be measured is detected by the laser detector, and a two-dimensional concentration lattice is generated, and the visible light imager Simultaneously imaging the object to be measured and forming a visible light image group; generating a second two-dimensional laser point cloud image based on the two-dimensional concentration lattice and the visible light image group. The invention also provides a device for generating a two-dimensional laser point cloud image based on laser scanning. The invention is used in the field of safety detection in industrial production and has the advantages of visualized monitoring, wide detection coverage and high detection precision.

Description

technical field [0001] This application relates to the field of safety detection in industrial production, in particular to a device and a device for generating two-dimensional laser point cloud images based on laser scanning for hazard detection. Background technique [0002] With the expansion of the chemical industry, a very small source of danger can also cause major social disasters. In order to protect the safety of people's lives and property, industrial production safety monitoring has become a key point that cannot be ignored. [0003] Point-type gas detection lasers are often used for safety detection in industrial production, but they cannot feed back visual images, nor can they provide real-time specific leak locations in the monitoring area, and cannot provide effective help for guiding production rescue. Usually, the staff carry a point-type gas detection laser to manually scan the tightness and stability of the machinery, gas tanks, and pipelines in the produc...
