Title:
RANGING APPARATUS AND SCANNING MECHANISM THEREOF, CONTROL METHOD, AND MOVABLE PLATFORM
Document Type and Number:
WIPO Patent Application WO/2020/142936
Kind Code:
A1
Abstract:
Provided are a ranging apparatus and a scanning mechanism thereof, a control method, and a movable platform. The scanning mechanism (3) comprises: a plurality of optical components (31); a plurality of motors (32), wherein the plurality of motors (32) correspond to the plurality of optical components (31) and have hollow rotors, and the plurality of optical components (31) are installed at rotors of the corresponding motors; and a controller (331) controlling the plurality of motors (32); or a plurality of controllers (331), at least one controller (331) controlling at least two motors (32). When a controller (331) controls at least two motors (32), the controller (331) controls, on the basis of a first synchronization control strategy, the at least two motors (32) to rotate at a predetermined angular difference. When a controller (331) controls one motor (32), the controller (331) controls, on the basis of a second synchronization control strategy, the motor (32) and the other at least one motor (32) to rotate at a predetermined angular difference. Various control strategies are adopted to control the plurality of motors (32) to rotate at a predetermined angular difference, thereby realizing synchronization of the plurality of motors (32) and reducing fluctuations in angular differences between the plurality of optical components (31).
