Title:
COMMUNICATION METHOD EMPLOYING DISTANCE MEASUREMENT DEVICE, DISTANCE MEASUREMENT DEVICE, AND MOBILE PLATFORM
Document Type and Number:
WIPO Patent Application WO/2023/123419
Kind Code:
A1
Abstract:
A communication method employing a distance measurement device, a distance measurement device, and a mobile platform. The communication method (300) comprises: the distance measurement device transmitting a detection signal to a current target (S310), the detection signal comprising a feature identification code; and the distance measurement device receiving an echo signal, acquiring distance information of the current target on the basis of the echo signal, and detecting whether the echo signal contains the feature identification code, and if the echo signal contains the feature identification code, the distance measurement device outputting the distance information of the current target (S320). The invention solves the problem of crosstalk between detection information sent by different distance measurement devices or sent at different times, and further improves the distance detection accuracy of the distance measurement device.
