Embodiment 1

[0062]figure 1 It is a schematic flow chart of this embodiment, a method for realizing GPS mapping camera screen coordinates on a mobile platform, comprising:

[0063] Step 101, obtaining the GPS latitude and longitude coordinates, direction, and altitude of the camera equipment on the mobile platform;

[0064] It should be noted that in order to accurately present the target GPS mapping coordinates on the screen, the positioning accuracy of the GPS equipment on the mobile platform, that is, the camera positioning equipment is required to be within 3 meters. Through RTK technology, the positioning accuracy is required to be less than 0.5 degrees in any direction , if the mobile platform has a rotatable pan-tilt camera, the horizontal and vertical accuracy of the pan-tilt is required to be less than 0.1 degrees.

[0065] Specifically, the acquisition process is as follows:

[0066] Use the sensor and RTK technology to obtain the initial data of the mobile platform camera and t...

Abstract

The invention provides a method and system for implementing GPS mapping camera picture coordinates on a mobile platform. The method comprises the following steps: obtaining GPS latitude and longitudecoordinates, direction and altitude of a mobile platform camera device; obtaining a position relationship between the mobile platform camera and a target GPS; and updating the coordinates G(X, Y) mapped by the target GPS on a real-time image in real time, and displaying the target GPS mapping coordinates in real time. The real-time display of the target GPS information position in the video imageof the mobile platform can be realized, and when the position of the mobile platform changes, the target GPS information position follows in real time, so that the positioning is accurate, and the technical problem that the mobile platform carrying the camera device cannot realize the actual scene and position information in the prior art is solved.

Description

technical field [0001] The invention relates to the field of real-time mapping of GPS coordinates, in particular to a method and system for realizing GPS mapping of camera screen coordinates on a mobile platform. Background technique [0002] With the development and progress of science and technology, camera equipment can be carried on mobile platforms, such as drones, vehicles and other mobile devices for mobile real-time monitoring and recording of various places. All walks of life have played an important role in personnel control, traffic monitoring, investigation and case handling, and environmental testing. [0003] At this stage, cameras carried by mobile devices can provide real-time video and play a role in real-time monitoring. However, at the same time, more background information cannot be provided for roads and buildings in the video. Video surveillance personnel need to be familiar with the scene information captured in order to make corresponding judgments a...
