Title:
INFRARED OBSTACLE DETECTION METHOD AND DEVICE AND ROBOT
Document Type and Number:
WIPO Patent Application WO/2019/056788
Kind Code:
A1
Abstract:
An infrared obstacle detection method and device and a robot, the method comprising: controlling a transmitting module to outwardly radiate infrared light (S110); obtaining first infrared light received by a first receiving module and second infrared light received by a second receiving module, wherein the arrangement position of the first receiving module relative to the transmitting module is such that the first infrared light comprises reflection light obtained by an obstacle reflecting the infrared light outwardly radiated by the transmitting module and infrared light within ambient light, and the arrangement position of the second receiving module relative to the transmitting module is such that the second infrared light is the infrared light in the ambient light (S120); and comparing the first infrared light and the second infrared light, and determining that an obstacle is detected when an energy difference between the first infrared light and the second infrared light is greater than a preset threshold (S130).
