specific Embodiment approach

[0110] According to another specific implementation manner of the present invention, step S13 specifically includes the following steps:

[0111] S131. Establish a node matrix, wherein the row and column coordinates represent node numbers, and the matrix data is node geographic location information; according to the prediction results, the nodes are divided into two types: important nodes and non-important nodes; wherein important nodes include line start and end nodes and intersection nodes; Non-essential nodes are internal nodes that belong only to a single line;

[0112] S132. For important nodes, construct an adjacency list of important nodes;

[0113] S133. For non-important nodes, perform matrix structure storage, where the row coordinates of the matrix indicate the lines to which they belong, and the column coordinates indicate the node numbers.

[0114] In step S132, for important nodes, due to the large amount of node data, considering the algorithm storage space and...

Abstract

The invention discloses an automatic inspection and real-time image acquisition transmission method of a railway line unmanned aerial plane. Through the method, automatic track plan inspection can be realized, visual navigation, image identification and obstacle avoidance are supported, parameters can be properly changed as no transmission delay influence is exerted, so the image identification rate is improved, a satellite communication network mode is fused with a traditional communication mode, high speed exchange for high-capacity image data can be realized, and the method further has an advantage of relatively high security.

Description

Technical field [0001] The invention relates to the field of unmanned aerial vehicle investigation, in particular to a method for automatic inspection and real-time image acquisition and transmission of aerial unmanned aerial vehicles on railway lines. Background technique [0002] Railway line inspection is the basic work of daily maintenance of railway lines. Inspection methods can be divided into manual inspection, manned helicopter inspection and drone inspection. Although manual inspection is the most commonly used inspection method, there have always been disadvantages such as slow efficiency and constraints by the climate and geographical environment. The machine inspection method is being widely studied and applied, especially the safe and efficient characteristics of UAV inspection. Man-machine has more and more application value. [0003] At present, most of the task planning for aerial drone inspections on railway lines adopts manual planning. Although this metho...
