Title:
ANTI-GLARE PHOTOGRAPHING DEVICE AND BUILDING ROBOT
Document Type and Number:
WIPO Patent Application WO/2023/071463
Kind Code:
A1
Abstract:
An anti-glare photographing device and a building robot. The anti-glare photographing device comprises a photographing module (1), a light supplementation assembly (2), a first polarizing member (3) and a second polarizing member (4), wherein the light supplementation assembly (2) emits light in a photographing direction of the photographing module (1) so as to illuminate a photographing target of the photographing module (1), the first polarizing member (3) is arranged on a light emergent side of the light supplementation assembly (2), the second polarizing member (4) is arranged on a light incident side of the photographing module (1), the first polarizing member (3) and the second polarizing member (4) do not overlap on a transmission light path, and the polarization direction of the first polarizing member (3) is set at a variable included angle of 0 to 90 degrees to a polarization direction of the second polarizing member (4). Light reflected from the photographing target to the photographing module (1) can be reduced, such that the alleviation of the problem of glare of the photographing target is facilitated.
