US 2014/0176038 A1 · POSITIONING METHOD AND POSITIONING DEVICE

Abstract

The present disclosure provides a positioning method and a positioning device. The positioning device includes: an emitter for emitting light beams to a to-be-positioned point and auxiliary positioning points; a receiver for receiving reflected light beams reflected by the to-be-positioned point and the auxiliary positioning points; a judging module for judging whether the reflected light beam reflected by the to-be-positioned point is received or not; and a calculating module for receiving a judging result from the judging module and determining height information of the to-be-positioned point according to the reflected light beams reflected by the to-be-positioned point and the auxiliary positioning points. Thus, the height information of the to-be-positioned point can be determined according to the reflected light beams reflected by the auxiliary positioning points even if the reflected light beam reflected by the to-be-positioned point cannot be received, which improves the success rate of the positioning.
