Indoor navigation method and indoor navigation device using laser radar and camera

Abstract

The invention discloses an indoor navigation method and indoor navigation device using a laser radar and a camera, and the method comprises the steps: obtaining a preset navigation path of a current scene, and obtaining a current time or a current illumination intensity value; when the current time is within a first preset time period or the current illumination intensity value is larger than a first preset illumination threshold value, obtaining first detection information through a first detection device, obtaining second detection information through a second detection device, and adjustingthe first detection information based on the second detection information to obtain adjusted detection information; when the current time is within a second preset time period or the current illumination intensity value is smaller than or equal to a first preset illumination threshold value, obtaining first detection information through a first detection device, obtaining second detection information through a second detection device, and adjusting the second detection information based on the first detection information to obtain adjusted detection information; and adjusting the preset navigation path based on the adjusted detection information to obtain an adjusted navigation path.

Description

technical field [0001] The present invention relates to the technical field of household appliances, in particular to an indoor navigation method using a laser radar and a camera and an indoor navigation device using a laser radar and a camera. Background technique [0002] With the continuous improvement of living standards and the continuous development of science and technology, sweeping robots, as a household device, are widely welcomed because they can reduce people's labor intensity at home and improve people's labor efficiency at home. [0003] Since the sweeping robot needs to operate automatically indoors, and there are various obstacles or obstacles in the room, the sweeping robot needs to have the ability to detect obstacles in front. Traditional sweeping robots are often equipped with infrared sensors to detect obstacles ahead. However, detection by infrared sensors has great limitations and detection deviations, resulting in large deviations in the path automati...

AI Technical Summary

Problems solved by technology

Traditional sweeping robots are often equipped with infrared sensors to detect obstacles ahead. However, detection by infrared sensors has great limitations and detection deviations, resulting in large deviations in the path automatically planned by the sweeping robot; in the prior art There is also a technical solution for collecting the image information in front of the sweeping robot through the camera, but the clarity of the image information collected by the camera has a great relationship with the surrounding light intensity, so the application scenarios of this solution have great limitations, so the existing The product cannot meet the user's needs for product accuracy and product adaptability, and the user experience is low
