Abstract

The invention discloses an unmanned platform indoor positioning system and method. The positioning system comprises a visual dynamic capturing unit, a signal processing unit and a GPS analog signal unit; the visual dynamic capturing unit is used for obtaining position information of an unmanned platform in an indoor three-dimensional space based on visual dynamic capturing; the signal processing unit is used for converting the position information of the unmanned platform in the indoor three-dimensional space into position coordinates in an earth centered earth fixed coordinate system; and theGPS analog signal unit is used for transmitting a pseudo GPS signal representing initial position information to start the unmanned platform, updating the real-time position of the unmanned platformby the position coordinates in the earth centered earth fixed coordinate system and sending the updated real-time position to the unmanned platform to realize positioning. The positioning system and method are high in universality, and can simulate operation of transmitting satellite positioning signals to realize positioning.

Description

Technical field

[0001] The invention relates to the technical field of indoor positioning, in particular to an unmanned platform indoor positioning system and positioning method. Background technique

[0002] At present, the indoor positioning technology of unmanned platforms such as unmanned aerial vehicles, AGV (Automated Guided Vehicle) and other moving bodies mostly uses optical flow, visual odometry, visual SLAM (robot simultaneous positioning and mapping) and other technical means . In an outdoor environment, GPS coordinates are generally sent to control the unmanned platform by planning a route, or manually controlled; while in an indoor environment, due to space constraints and signal attenuation or shielding, the unmanned platform cannot receive GPS coordinates. Its positioning and navigation solution Outdoor positioning based on GPS or Beidou signals cannot be used. At the same time, due to the heterogeneity of the environment and technical maturity, as well as hardwa...
