Problems solved by technology

At present, the video acquisition and video processing technologies of automatic monitoring technology are becoming more and more mature. Therefore, the state detection of rails, sleepers and their connectors can be carried out based on image recognition. However, in the actual detection process, it is found that the collected images may have certain This kind of deflection makes the direction of the rails and sleepers in the image used in the image recognition process inconsistent, so it needs to be processed

Embodiment 1

[0062] The embodiment of the present invention discloses a method for intelligently processing railway video data, such as figure 1 As shown, the method includes:

[0063] S101. Acquire an inspection video image taken by an inspection robot, where the inspection video image includes railway rails.

[0064] S103. Construct a plane Cartesian coordinate system, and generate a grayscale image corresponding to the inspection video image in the plane Cartesian coordinate system.

[0065] S105. Generate an edge image according to the grayscale image.

[0066] The embodiment of the present invention obtains the adjusted angle based on the analysis of the edge image, so the accuracy of the edge image is crucial to the effect of the embodiment of the present invention. To this end, the embodiment of the present invention first discloses a method for generating an edge image based on the grayscale image, such as figure 2 As shown, the method includes:

[0067] S1051. Acquire the gra...

Abstract

The present invention provides a method and device for intelligently processing railway video data. The method includes acquiring an inspection video image taken by an inspection robot, wherein the inspection video image includes railway rails; constructing a plane Cartesian coordinate system, and Generate a grayscale image corresponding to the inspection video image in a Cartesian coordinate system; generate an edge image according to the grayscale image; analyze the edge image to obtain an adjustment angle, and rotate the grayscale counterclockwise according to the adjustment angle degree image to obtain the target image, so that the railway rail in the target image is parallel to the Y-axis of the plane Cartesian coordinate system. The invention processes the inspection video image, and adjusts the direction of the rail by rotating the image, so as to facilitate the positioning and analysis of other related components based on the position of the rail in subsequent image recognition.

Description

technical field [0001] The invention relates to the field of data processing, in particular to a method and device for intelligently processing railway video data. Background technique [0002] Railway track, referred to as rail, rail, track, etc. It is used on the railway and cooperates with the switch, so that the train can walk without turning. The track usually consists of two parallel steel rails. The rail is fixed on the sleeper, and the ballast is under the sleeper. Rails made of steel can withstand greater weight than other materials. Sleepers, also known as sleepers, or road sleepers, function to separate and distribute the weight of the rails, keep the rails fixed, and maintain the gauge of the rails. [0003] The status detection of rails, sleepers and their connectors is an important part of railway inspection. At present, the video acquisition and video processing technologies of automatic monitoring technology are becoming more and more mature. Therefore, ...
