Title:
OBSTACLE DETECTION METHOD AND DEVICE, AND UNMANNED AERIAL VEHICLE
Document Type and Number:
WIPO Patent Application WO/2018/214644
Kind Code:
A1
Abstract:
Disclosed are an obstacle detection device (58) and method, and an unmanned aerial vehicle (50). The obstacle detection device (58) comprises a distance measurement and calculation unit (30); a receiving tube (32) connected to the distance measurement and calculation unit (30); at least two emitter tubes (1, n, 59) connected to the distance measurement and calculation unit (30); and a measurement controller (20) connected to the at least two emitter tubes (1, n, 59), wherein the measurement controller (20) is used for controlling the at least two emitter tubes (1, n, 59), the receiving tube (32) is used for receiving an optical signal, the optical signal received by the receiving tube (32) is an optical signal formed by emission by the emitter tubes (1, n, 59) and reflection by an obstacle (40), and wherein the distance measurement and calculation unit (30) is used for acquiring a phase of the optical signal emitted and a phase of the optical signal received, and according to a phase difference between the phase of the optical signal emitted and the phase of the optical signal received, calculating the distance between the obstacle (40) and the obstacle detection device (58), which can effectively enlarge the range of obstacle measurement.
