The invention provides a positioning method and device, which are applied to a vehicle including a positioning terminal, and the positioning terminal includes a GPS locator, a 3D geographic information model, a camera and a laser range finder installed in the vehicle. The method includes: obtaining the current precise position of the vehicle through the two-dimensional images collected by the 3D geographic information model, the GPS locator and the camera, and identifying a preset reference object from the two-dimensional image; The depth information of the reference object acquired in the depth image information is recorded as the first depth information, and the precise position of the reference object is calculated and recorded; when the recognition of the collected two-dimensional image is lower than the preset resolution, the last recorded The reference object of the target is used as the target reference object, and the first depth information and precise position of the target reference object are obtained, so as to obtain the second depth information of the target reference object from the currently collected depth image information, and then the current precise position of the vehicle is obtained. Location.
Description
technical field [0001] The present invention relates to the technical field of positioning, in particular to a positioning method and device. Background technique [0002] Existing means of transportation are usually positioned through a positioning signal provided by a GPS positioning terminal. However, the use of GPS positioning terminals for positioning has the following problems: on the one hand, errors in positioning signals may be caused by satellite orbit errors; Causing occasional errors, resulting in inaccurate positioning. Contents of the invention [0003] In view of this, the purpose of the present invention is to provide a positioning method and device to improve the above problems. [0004] In order to achieve the above object, the purpose of the embodiments of the present invention is to provide a positioning method, which is applied to a vehicle including a positioning terminal, and the positioning terminal includes a GPS locator, a 3D geographic informat...
