Abstract

The invention discloses a mobile equipment positioning method and a mobile equipment positioning device. The mobile equipment positioning method comprises the following steps: determining a first group of pose parameters when the mobile equipment shoots a current frame image, and determining a top view of the current frame image; determining a plurality of second groups of pose parameters based onthe first groups of pose parameters; in the high-precision map, determining a plane area in a preset range of a geographic position when the current frame image is shot; projecting the top view intothe plane area based on the plurality of second groups of pose parameters to obtain a plurality of second projection drawings; and based on the matching degree between the plurality of second projection images and the image content of the plane area in the high-precision map, determining a pose parameter of the mobile device when the mobile device shoots the current frame image from the pluralityof second group pose parameters. According to the embodiment of the invention, the method can greatly reduce the impact on the positioning precision from an environment condition, improves the positioning precision, and greatly reduces the positioning cost through the visual camera.
