Abstract
The invention discloses a video-based carriage overload monitoring method. The method concretely comprises the following steps: adopting the middle gangway of a carriage as a detection area, and acquiring the video image of the detection area; selecting one frame of the video image as the current frame, and analyzing whether a face characteristic image exists in the gangway area by using the above video; determining the current carriage is not overloaded if the face characteristic image does not exist; continuously tracing the face characteristic image if the face characteristic image exists, and determining the current carriage is not overloaded if the face characteristic image still exists in a preset time threshold and the movement range of the face characteristic image does not exceed a position threshold; and directly determining whether face characteristic images exist or not if above two face characteristic images exist in the detection area, determining the current carriage is overloaded if the above two face characteristic images still exist, and repeatedly determining if not.
Description
Technical field
The present invention relates to the overcrowding method for supervising of a kind of vehicle based on video.
Background technology
Overload is the something making everyone headache always, although also have a little helpless, life-and-death matter, can not general idea.The means of existing detection overload are comparatively single, need traffic police at the outpost of the tax office, vehicle of stopping, get on the bus and carry out manual detection, hinder vehicle to advance and do not say, also consume administration cost greatly.
The development of Video Analysis Technology at any time, has occurred that the Video Detection Algorithm of being correlated with may be used for personnel or the moving Object Detection of specific region.
Summary of the invention
The present invention is directed to the proposition of above problem, and the overcrowding method for supervising of a kind of vehicle based on video of development, there are following steps:
-using the central gangway of vehicle as surveyed area, the video image in acquisition testing region;
-choose a frame video image wherein as present frame, use the image that whether there is face characteristic in video analysis aisle region;
-if there is not the image of face characteristic, then judge that current passenger vehicle is as non-overload condition; If there is face characteristic image, continue to follow the tracks of this face characteristic image, if face characteristic image still exists in the time threshold of setting, and moving range is no more than position threshold, then judge that current passenger vehicle is as non-overload condition.
If there is plural face characteristic image in surveyed area, then directly temporally whether threshold determination face characteristic image still exists; If exist, then judge Current vehicle overload; If do not exist, then repeat determination step.
Have step: when detecting overload of vehicle, remote control center assigns instruction, control vehicle automatic retarding and stop, locked engine, and searching database, notify local traffic police.
Also had before described step " using the central gangway of vehicle as surveyed area, the video image in acquisition testing region ": the video image realizing collection vehicle passageway, determine benchmark image.
Owing to have employed technique scheme, the overcrowding method for supervising of a kind of vehicle based on video provided by the invention, by the detection to vehicle passageway, achieve the full-automatic judgement to overload of vehicle situation, the technology maturation adopted, is skillfully constructed, and is extremely suitable for promoting on a large scale and using.
Accompanying drawing explanation
In order to the technical scheme of clearer explanation embodiments of the invention or prior art, introduce doing one to the accompanying drawing used required in embodiment or description of the prior art simply below, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is process flow diagram of the present invention
Embodiment
For making the object of embodiments of the invention, technical scheme and advantage clearly, below in conjunction with the accompanying drawing in the embodiment of the present invention, clear complete description is carried out to the technical scheme in the embodiment of the present invention:
As shown in Figure 1: the overcrowding method for supervising of a kind of vehicle based on video, has following steps:
-using the central gangway of vehicle as surveyed area, the video image in acquisition testing region;
-choose a frame video image wherein as present frame, use the image that whether there is face characteristic in video analysis aisle region;
-if there is not the image of face characteristic, then judge that current passenger vehicle is as non-overload condition; If there is face characteristic image, continue to follow the tracks of this face characteristic image, if face characteristic image still exists in the time threshold of setting, and moving range is no more than position threshold, then judge that current passenger vehicle is as non-overload condition.
If there is plural face characteristic image in surveyed area, then directly temporally whether threshold determination face characteristic image still exists; If exist, then judge Current vehicle overload; If do not exist, then repeat determination step.
Have step: when detecting overload of vehicle, remote control center assigns instruction, control vehicle automatic retarding and stop, locked engine, and searching database, notify local traffic police.
Also had before described step " using the central gangway of vehicle as surveyed area, the video image in acquisition testing region ": the video image realizing collection vehicle passageway, determine benchmark image.
Owing to have employed technique scheme, the overcrowding method for supervising of a kind of vehicle based on video provided by the invention, by the detection to vehicle passageway, achieve the full-automatic judgement to overload of vehicle situation, the technology maturation adopted, is skillfully constructed, and is extremely suitable for promoting on a large scale and using.
The above; be only the present invention's preferably embodiment; but protection scope of the present invention is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the present invention discloses; be equal to according to technical scheme of the present invention and inventive concept thereof and replace or change, all should be encompassed within protection scope of the present invention.
Claims (4)
1., based on the overcrowding method for supervising of vehicle of video, there are following steps:
-using the central gangway of vehicle as surveyed area, the video image in acquisition testing region;
-choose a frame video image wherein as present frame, use the image that whether there is face characteristic in video analysis aisle region;
-if there is not the image of face characteristic, then judge that current passenger vehicle is as non-overload condition; If there is face characteristic image, continue to follow the tracks of this face characteristic image, if face characteristic image still exists in the time threshold of setting, and moving range is no more than position threshold, then judge that current passenger vehicle is as non-overload condition.
2. the overcrowding method for supervising of a kind of vehicle based on video according to claim 1, is further characterized in that: if there is plural face characteristic image in surveyed area, then directly temporally whether threshold determination face characteristic image still exists; If exist, then judge Current vehicle overload; If do not exist, then repeat determination step.
3. the overcrowding method for supervising of a kind of vehicle based on video according to claim 1, is further characterized in that to have step: when detecting overload of vehicle, remote control center assigns instruction, control vehicle automatic retarding to stop, locked engine, and searching database, notify local traffic police.
