Title:
UNMANNED AERIAL VEHICLE AND METHOD FOR DESIGNING LENS
Document Type and Number:
WIPO Patent Application WO/2019/183955
Kind Code:
A1
Abstract:
Disclosed in the present application is an unmanned aerial vehicle (10), which comprises a fuselage (12) and a visual obstacle avoidance system (14). The visual obstacle avoidance system (14) is mounted on the fuselage (12). The visual obstacle avoidance system (14) comprises a binocular vision module (142) and a light-supplementing device (144), and the light-supplementing device (144) is located between two cameras (1422) of the binocular vision module (142). The light-supplementing device (144) comprises a light source (1442) and a lens (1444), and the lens (1444) comprises a convex surface (14442) that acts as a light incidence surface and a light-emitting flat surface (14444) that is opposite to the convex surface, wherein the convex surface (14442) is a non-spherical surface or a free-form surface. The light source (1442) is disposed at a side of the convex surface (14442). The lens (1444) is configured to project a light beam emitted from the light source (1442) to form a light spot that matches the field-of-view angle of the binocular vision module (142). Further disclosed in the present application is a method for designing a lens.
