Title:
INDOOR ENVIRONMENT-BASED AUXILIARY LIGHT VISION DETECTION DEVICE, AND MOBILE ROBOT
Document Type and Number:
WIPO Patent Application WO/2021/082657
Kind Code:
A1
Abstract:
An indoor environment-based auxiliary light vision detection device, and a mobile robot. The auxiliary light vision detection device comprises a linear light source emitter (104) and a camera (103), an emission direction of the linear light source emitter (104) is not parallel to the indoor horizontal ground, so that an emitted linear light source intersects with a visual angle of the camera (103) to form an effective detection area. The auxiliary light vision detection device is assembled at the front end of a housing of a body (101) of the mobile robot, and an emission end of the linear light source emitter (104) of the auxiliary light vision detection device and a lens of the camera (103) are both configured to face an advancing direction of the mobile robot. Compared with the prior art, during indoor environment visual navigation, the linear light source emitter (104) assists in detecting obstacles at a short distance, the situation that the camera (103) always photographs scene pictures containing reflected light spots is avoided, and the interference of reflected light spots in an indoor environment boundary area on obstacle detection by the single camera (103) is reduced.
