Problems solved by technology

The limitation of this solution is that the pattern is easy to be stained and difficult to maintain. For example, in a restaurant equipped with service robots, it is very difficult to clean the positioning QR code on the ceiling; it provides little information and small coverage. For example, in large-scale In a storage environment or a multi-floor shopping mall, a large number of positioning points need to be configured. It is difficult to design a unique pattern for each positioning point, and it is not easy to change the pattern

Abstract

The invention relates to the technical field of space positioning, and provides an illumination light positioning method based on an industrial camera, and the method comprises the steps: obtaining an image in a preset region through the industrial camera; identifying a corner point of a light source area of an illuminating lamp in the image, performing rotation processing on the light source area, and determining pixel coordinate information of the rotated corner point in the image; decoding the light source area in the image based on a preset decoding rule of the OOK modulation light information, and obtaining ID information of the illuminating lamp; obtaining the world coordinate information of the illuminating lamp in world coordinates according to the ID information; and calculating world coordinate information of the industrial camera based on the pixel coordinate information, the world coordinate information and calibration parameters of the industrial camera. The device is high in positioning precision and easy to maintain.

Description

technical field [0001] The invention relates to the technical field of optical positioning, in particular to an industrial camera-based illumination light positioning method, device and related equipment. Background technique [0002] As a means of indoor positioning, visible light positioning has the advantages of high precision, easy deployment, wide coverage, energy saving and environmental protection compared with Bluetooth, infrared, WiFi and other technologies. [0003] Existing solutions that use cameras to receive location information often use special patterns such as QR codes to provide signs of specific locations. The limitation of this solution is that the pattern is easy to be stained and difficult to maintain. For example, in a restaurant equipped with service robots, it is very difficult to clean the positioning QR code on the ceiling; it provides little information and small coverage. For example, in large-scale In a storage environment or a multi-floor shop...
