摘要

Provided by the present invention are a positioning method and positioning system for a fully mechanized mining face, wherein the positioning method comprises: acquiring absolute coordinates of a target image in an absolute coordinate system; if a depth camera device (200) collects a target image of one group of targets (100), then determining camera coordinates of the target image in a coordinate system of the depth camera device (200); determining absolute coordinates of the depth camera device (200) according to the absolute coordinates of the target image and the camera coordinates; and if the depth camera device (200) does not collect the target image, then controlling a tracking camera device (300) to turn on, and according to a conversion matrix between the coordinate system of the depth camera device (200) and the absolute coordinate system and a conversion matrix between a coordinate system of the tracking camera device (300) and the coordinate system of the depth camera device (200) at the time when the tracking camera device (300) is turned on, obtaining absolute coordinates of the tracking camera device (300) relative to the absolute coordinate system. The present invention solves the problem in the prior art in which continuous high-precision three-dimensional positioning coordinates of a target object cannot be obtained when there is no GPS signal.
