Abstract
The invention discloses a large-size vehicle positioning method for a power transmission and distribution line channel. The method is characterized by collecting video images through a front-end camera and carrying out decompression on the collected video images to enable the video images to be decomposed into YUV pictures required for intelligent analysis; converting the YUV pictures into RGB pictures; decomposing the pictures into 25 frames of RGB pictures within a second, and randomly drawing 10 frames of pictures from the RGB pictures to carry out analysis and comparison; comparing the next frame of picture with the previous frame of picture, and updating background environment in real time by utilizing self-learning, and drawing a target object therefrom; and carrying out shape detection on the target object first, and when detecting that the target object is a large-size vehicle, then, carrying out positioning and calculating on the vehicle. The method can carry out identification on large-size vehicle conditions of the power transmission and distribution line channel conveniently and timely.
Description
Technical field
The present invention relates to the recognition methods of a kind of transmission and distribution line paths autocrane intelligent video.
Background technology
For electric power facility, how by analyzing transmission and distribution line paths oversize vehicle situation, being the target of technical staff's long-sought, not having desirable method yet so far.
Summary of the invention
The object of the present invention is to provide a kind of transmission and distribution line paths oversize vehicle localization method that can identify transmission and distribution line paths oversize vehicle situation conveniently, in time.
Technical solution of the present invention is:
A kind of transmission and distribution line paths oversize vehicle localization method, is characterized in that: concrete steps:
(1) video image is gathered by front-end camera;
(2) decompress gathering the video image of returning, and resolve into the YUV picture of intellectual analysis needs.
(3) YUV picture is converted to RGB picture;
25 frame RGB pictures can be resolved into (4) one seconds, then therefrom randomly draw 10 frames and carry out analysis contrast;
(5) a rear frame picture and former frame picture are contrasted, and utilize self study, real-time update background environment, therefrom detaches target object, first carries out body detection to target object, when determine be oversize vehicle after, calculating is positioned to it.
The present invention can facilitate, identify transmission and distribution line paths oversize vehicle situation in time; Moving target is detected, follows the tracks of, and the adventurous oversize vehicle of electric transmission line channel is identified, located., improve the performance of real-time early warning, in advance danger nipped in the bud, increased work efficiency by man-computer cooperation mode, accuracy rate.
Below in conjunction with embodiment, the invention will be further described.
Embodiment
A kind of transmission and distribution line paths oversize vehicle localization method, concrete steps:
(1) video image is gathered by front-end camera;
(2) decompress gathering the video image of returning, and resolve into the YUV picture of intellectual analysis needs.
(3) YUV picture is converted to RGB picture;
25 frame RGB pictures can be resolved into (4) one seconds, then therefrom randomly draw 10 frames and carry out analysis contrast;
(5) a rear frame picture and former frame picture are contrasted, and utilize self study, real-time update background environment, therefrom detaches target object, first carries out body detection to target object, when determine be oversize vehicle after, calculating is positioned to it.
Transmission and distribution line paths oversize vehicle localization method with intelligent image analytical technology for core, so-called intelligent image analytical technology uses computer picture Visual analysis techniques exactly, by background in scene being separated with target and then analyzing and follow the trail of the target occurred in camera scene, and need the vertical range determining that video camera distance vehicle is advanced, when determine be oversize vehicle after, calculating is positioned to it.
The picture breakdown of front-end camera collection is become picture one by one, select suitable frame to pass to core intelligence image analysis module according to actual conditions and carry out graphical analysis, the rear image of a frame and the image of former frame are contrasted, and utilize the slight change of automatic learning scene, thus set up and safeguard the background environment of a real-time update, this background environment can slight change environmentally and changing.Again the thing beyond background is therefrom detached, thus form the object on picture.Because every sample object can detach from background, and the vertical range of video camera distance vehicle always, and the pixel coordinate corresponding in picture of object also can calculate, and finally just can position oversize vehicle according to its coordinate position.
Claims (1)
1. a transmission and distribution line paths oversize vehicle localization method, is characterized in that: concrete steps:
(1) video image is gathered by front-end camera;
(2) decompress gathering the video image of returning, and resolve into the YUV picture of intellectual analysis needs;
(3) YUV picture is converted to RGB picture;
25 frame RGB pictures can be resolved into (4) one seconds, then therefrom randomly draw 10 frames and carry out analysis contrast;
(5) a rear frame picture and former frame picture are contrasted, and utilize self study, real-time update background environment, therefrom detaches target object, first carries out body detection to target object, when determine be oversize vehicle after, calculating is positioned to it.
