Real-time image transmission system and method for unmanned flight platform

Abstract

The invention relates to a real-time image transmission system of an unmanned flight platform, comprising: a picture dividing device arranged on the unmanned flight platform, for receiving a high-definition aerial photograph image, and dividing the high-definition aerial photograph image into a plurality of pixel blocks of 50x50 pixels; a pixel block selecting device arranged on an unmanned aerialplatform, configured to draw an Archimedes curve in the high-definition aerial photograph image from a center pixel point of the high-definition aerial photograph image as a starting point, and takea pixel block passing through the Archimedes curve in the high-definition aerial photograph image as an error detection pixel block to obtain a plurality of error detection pixel blocks; a picture analysis apparatus provided on the unmanned flight platform for performing picture analysis processing for each error detection pixel block. The invention also relates to a real-time image transmission method of an unmanned flight platform. Through the invention, the number of windows of the target building can be accurately obtained in real time, and valuable reference data can be provided for the construction of the adjacent buildings which are not started in the follow-up.

Description

technical field [0001] The invention relates to the field of real-time image transmission, in particular to a real-time image transmission system and method for an unmanned aerial platform. Background technique [0002] With the development of aerial photography technology, unmanned aerial vehicles, especially quadcopters, have been developed and applied considerably. In a professional environment, this kind of aerial reconnaissance takes a long time to find a view, has high requirements for shooting, and is operated by a professional operator. Therefore, it is generally used to shoot repeatedly, and then edit and splice in the later stage to obtain the best presentation effect that users can enjoy. Way. Therefore, in a professional environment, those skilled in the art are concerned about the improvement of shooting effects, such as: anti-shake, stabilization, etc. [0003] Most of the existing video image returns are based on analog video signals, and the images are not ...

Problems solved by technology

However, the current research on 3D reconstruction of UAV sequence images is still in its infancy, and there are mainly the following problems: (1) Compared with ground images, 3D reconstruction based on UAV sequence images is generally a 3D reconstruction of a large amount of data and a large scene; (2) Most of the mature algorithms in computer vision are directly applied to the 3D reconstruction of UAV sequence images; (3) The auxiliary information with low precision is not fully utilized

[0004] However, these prior art calculations are too large, especially the calculations in three-dimensional image processing often lead to excessive power consumption in the image processing and data transmission of the aircraft
