Problems solved by technology

In the outdoor environment, the unmanned platform is generally controlled by sending GPS coordinates through the planned route, or manually controlled; while in the indoor environment, due to space constraints and signal attenuation or shielding, the unmanned platform cannot receive GPS coordinates, and its positioning and navigation scheme Outdoor positioning methods based on GPS or Beidou signals cannot be used
At the same time, limited by the diversity of the environment and the maturity of technology, as well as hardware and cost issues, the positioning scheme of indoor unmanned platforms, especially in the application of professional fields, lacks a versatile technical solution

Embodiment Construction

[0028] The present invention will be described in detail below with reference to the drawings and embodiments.

[0029] This embodiment provides an unmanned platform indoor positioning system, such as figure 1 As shown, it includes a visual dynamic capture unit 1, a signal processing unit 2, and a GPS analog signal unit 3.

[0030] The visual dynamic capture unit 1 includes eight motion capture cameras, a data switch and a motion capture data processing module. The motion capture cameras are respectively connected to the corresponding data switch, and the data switch is connected to the capture data processing module. The motion capture camera is based on the principle of passive optics and supports simultaneous capture of multiple target objects. It has the characteristics of enhanced infrared illumination, full scene coverage, high-speed acquisition and high image resolution. The three-degree-of-freedom position accuracy of the target object obtained by the visual dynamic captur...

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...
