Abstract

The invention discloses a visible light positioning method and device, computer equipment and a storage medium. The method comprises steps of carrying out the image collection of a light source objectat a transmitting end through image collection equipment, and generating a to-be-processed image; preprocessing the to-be-processed image to generate a preprocessed image; constructing a sample template image, zooming the sample template image for N times to generate a template image set to be matched, the template image set to be matched comprising N template images to be matched; matching the preprocessed image with each to-be-matched template image, and determining a target region of interest in the to-be-processed image; tracking a target region of interest in the to-be-processed image byadopting a small-range surrounding approximation method to obtain tracking information; and if the tracking information is the first tracking information, carrying out information decoding on the region of interest of the preprocessed image to obtain target positioning information, thereby improving efficiency of obtaining the region of interest (ROI) of the visible light source by adopting a visible light positioning method.

Description

technical field [0001] The present invention relates to the field of visible light communication, in particular to a visible light positioning method, device, equipment and medium. Background technique [0002] In recent years, indoor visible light positioning technology has received great attention and has broad application prospects. Indoor visible light positioning technology can help people quickly reach designated locations in large indoor places. However, there are still many obstacles in the actual application process of the current indoor visible light positioning technology, such as real-time robustness and other issues. In the indoor visible light technology, it takes a long time to obtain the region of interest (ROI) of the visible light source in the whole positioning technology, and the anti-interference performance is poor. However, if the general tracking technology is used, it needs to be manually initialized, which is difficult. applied in practice. Theref...
