Description
Technical field
The present invention relates to technical field of image acquisition, specially a kind of highway bridge image acquiring method.
Background technique
Country is huge to the investment of the infrastructure in China, especially builds bridge and repairs the roads, will also be to bridge after the hypothesis of bridge
Health monitored in real time, several many bridges are being open to traffic in use process, and crack, vehicle occurs to some extent in bridge floor
Rut gathers around the diseases such as packet, pit slot, causes comparable economic loss, traffic accident is also occurred that when serious.Therefore, to bridge floor quality
Monitoring, assessment and routine servicing it is extremely important, the most of detection modes in China still use the judgement at artificial scene at present, this
Kind of mode is found the problem not in time, inefficiency, and due to needing artificial scene judgement, can only in wagon flow few, highway
Road surface, which occupies, just can be carried out live judgement under few opportunity, this necessarily causes real-time judge difficult, cannot remove detection highway in time
Road surface.
Secondly, also there is part, bridge machinery is to set on bridge surface using the detection mode of modernization in the prior art
Monitoring camera is set, shooting is carried out by camera and obtains image, analyzes image then to find disease, but it is often schemed
It is influenced as unintelligible, and by weather and light factor.
Further, since it only has found disease in picture, but before the highway in the display of picture and reality
Position is not so easy correspondence, generally requires to go the position of careful corresponding picture according to picture, this causes even if knowing disease
True disease position is searched on practical road surface later and positions still difficulty, accordingly, it is desirable to be able to locating module is provided,
It may be implemented to position and shooting combine, how in the image of shooting location data is included in, so as to pass through picture
With regard to the specific location that quick search goes wrong, positioned, so as to quickly find the practical disease position of highway, into
Row highway maintenance, to improve the timeliness of maintenance.
In addition, in the prior art, picture how much is shot, then by manual analysis picture, to go to search, detect and sentence
Breaking face whether there is disease, and find out out position, but the Defect inspection frequency of bridge is relatively high, is here necessarily required to clap
Many pictures are taken the photograph, in order to analyze, these shooting pictures are required to manual analysis, then, due to artificial human nature low efficiency, and shoot
Picture it is again more, this necessarily leads to road surface detection, judges very difficult, and low efficiency；Accordingly, it would be desirable to provide one kind
The display of virtual reality may be implemented, i.e., display system, which can be shown, shoots problem area, and shows on map, thus
Increase the effect of visualization of the image-taking system, to increase new technical effect.
In addition, when obtain highway bridge image when, due to inevitably, exist on the road the automobile moved back and forth and
Other vehicles in use, these automobiles moved back and forth and vehicle in use will necessarily block the road surface of shooting, therefore lead to road surface
There is not detectable blind area in the perfection that cannot be shot, this necessarily causes pavement disease to find incomplete situation, therefore, it is desirable to
It can be carried out the picture comparative analysis and splicing of more Intelligent fine, while reducing the defect being blocked.
Based on above-mentioned technical problem, it is desirable to provide a kind of significantly more efficient highway bridge image-taking system and method, with
Just overcome drawbacks described above.
Summary of the invention
The purpose of the present invention is to provide a kind of highway bridge image acquiring methods, pass through positioning device and camera system
Synergy, realize shooting image and outdoor scene position combine, so as to help maintenance personnel quickly find out disease letter
Specific location is ceased and obtained, and can obviously highlight the disease of acquisition system acquisition by display module, reduces people
The simple and many and diverse labour that work is judged according to picture, in addition, the system is drawn by carrying out gridding to the region of shooting
Point, and by judging whether there is the moving objects such as automobile, the picture for finally carrying out obtaining without motion object merges, and is formed without fortune
The automobile of animal, so as to solve the problems mentioned in the above background technology.
