Embodiment

[0069] A method for automatically positioning the coordinates of the scene in the real-time video fixed track inspection in this embodiment includes the following steps:

[0070] The first step is to obtain the MSE parameters.

[0071]MSE (Motion state of equipment) and equipment motion state, including start time, stop time, travel time, turning angle, travel direction, speed, acceleration and slope.

[0072] Obtain MSE parameters: start time T0, stop time Tn, travel time t, travel direction (forward: U, backward: D), turning angle (α, α=0-360°), velocity v, acceleration a and slope p.

[0073] One way of obtaining the MSE parameter is: obtaining from a fixed track inspection device.

[0074] One way to obtain the MSE parameters is: each time the inspection equipment is restarted, set an initial state MSE for the inspection equipment and save it, obtain the MSE parameters, and update the MSE synchronously when the inspection equipment is in motion, and record it as Current ...

Abstract

The invention discloses a method for automatically positioning the coordinates of scenes in a real-time video fixed-trace inspection tour. The method comprises the following steps: S1, acquiring MSE parameters; S2, determining the coordinates of a video display area, using a scene to be acquired as a reference object, manually calibrating the scene so as to obtain the coordinates of the referenceobject, and recording travelling time; S3, simultaneously performing steps A and B according to the acquired MSE parameters: step A, calculating a matching relation between the moving MSE of inspection equipment and the coordinates of scenes in a video on a screen, determining the coordinates of scenes in the video on the screen, marking and storing the coordinates, and continuously updating the coordinates of the scenes so as to realize tracking display of the scenes; and step B, calculating a matching relation between the moving MSE of the inspection equipment and the coordinates of displayareas in the video on the screen, calling the operation time of the inspection equipment and determining the real-time video display areas of the screen; and S4, marking and displaying the coordinatesof scenes in the video on the screen. The method of the invention has the advantages of low occupation of hardware resources, convenience for processing of mass videos, no influence by image qualityand illumination conditions, and high accuracy.

Description

technical field [0001] The invention belongs to the fields of information technology and automation technology, and in particular relates to a method for automatically positioning coordinates of a scene in real-time video fixed track inspection. Background technique [0002] Video recognition technology mainly includes three links: front-end video information collection and transmission, intermediate video detection, and back-end analysis and processing. Video recognition requires the front-end video capture camera to provide a clear and stable video signal, and the quality of the video signal will directly affect the effect of video recognition. After video recognition, determine the position of the scene on the display screen and then perform standardization. [0003] However, the existing video recognition technology has the following defects: [0004] 1. The monitoring environment, such as light and video effects, have a great influence on the accuracy of video positio...
