Abstract
The invention relates to a mapping system for a traffic accident scene. The mapping system comprises a first image gatherer, an image recognizer, a second image gatherer, an image mosaicking processor, a central processor, an image drafting device, a color printer and a wireless transmitting device. The first image gatherer is connected with the central processor through the image recognizer; the second image gatherer is connected to the central processor by the image mosaicking processor; the central processor is respectively connected with the wireless transmitting device and the image drafting device; and the image drafting device is connected with the color printer. The mapping system has the advantages of simple structure and reasonable design, provides on-site data processing and scene drafting, greatly shortens the scene handling time, improves work efficiency, and ensures safety.
Description
Technical field
The invention belongs to survey field, particularly relate to a kind of scene of a traffic accident mapping system.
Background technology
Current China traffic accident situ mapping method is mainly based on manual measurement, and floor photo, video recording are auxiliary.Not only workload is large, spended time is long in artificial mapping, mapping precision is low, also can affect normal traffic order because the road occupying time is long, cause secondary traffic hazard etc.In recent decades, China's economy develops rapidly, and the total recoverable amount of motor vehicle progressively increases progressively, and road traffic flow increases thereupon, and road traffic condition go fromes bad to worse.The reasons such as driveship is comparatively low in addition, control of traffic and road is not good at, China's road traffic accident grows with each passing day, and directly results in huge casualties and economic loss.In the world, road traffic accident is also cause death and disabled one of the main reasons.In recent years, along with the development of digital camera and digital image processing techniques, utilizing photogrammetric technology to carry out scene of a traffic accident exploration becomes possibility.Photogrammetric technology, because of particular advantages such as equipment cost are low, easy to use, is being carried out application in the U.S., Japan and some countries of Europe, and is being achieved obvious effect.But the difficult point applying photogrammetric technology in China is: according to the Ministry of Public Security of China standard, traffic accident scene diagram must be drawn in the scene of the accident, and to be signed accreditation by accident litigant.Existing photogrammetric technology, comprise the photogrammetric software of the various scene of a traffic accident and equipment, although can greatly shorten scene of the accident data acquisition time, follow-up data process and drawing course more complicated and time-consuming, be difficult to meet the requirement of drawing in the scene of the accident and exporting scene photo.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, a kind of scene of a traffic accident mapping system is provided, this mapping system structure is simple, design science is reasonable, can on-site data processing be provided and draw scene photo, substantially reduce the site disposal time, improve work efficiency, ensure safety.
The present invention solves its technical matters and is achieved through the following technical solutions:
A kind of scene of a traffic accident mapping system, it comprises the first image acquisition device, image recognizer, the second image acquisition device, image mosaic processor, central processing unit, image plotting device, color printer and wireless launcher, first image acquisition device connects central processing unit by image recognizer, second image acquisition device connects central processing unit by image mosaic processor, this central processing unit connects wireless launcher and image plotting device respectively, and this image plotting device connects color printer.
Above-mentioned wireless launcher is cdma wireless transmitter module.
The first above-mentioned image acquisition device is high-definition camera.
The second above-mentioned image acquisition device is high definition camera.
Advantage of the present invention and beneficial effect are:
This a kind of scene of a traffic accident mapping system, it comprises the first image acquisition device, image recognizer, second image acquisition device, image mosaic processor, central processing unit, image plotting device, color printer and wireless launcher, first image acquisition device connects central processing unit by image recognizer, second image acquisition device connects central processing unit by image mosaic processor, this central processing unit connects wireless launcher and image plotting device respectively, this image plotting device connects color printer, structure of the present invention is simple, design science is reasonable, can on-site data processing be provided and draw scene photo, substantially reduce the site disposal time, improve work efficiency, ensure safety.
Accompanying drawing explanation
Fig. 1 is anatomical connectivity schematic diagram of the present invention.
Embodiment
Below by specific embodiment, the invention will be further described, and following examples are descriptive, is not determinate, can not limit protection scope of the present invention with this.
A kind of scene of a traffic accident mapping system, it comprises the first image acquisition device, image recognizer, the second image acquisition device, image mosaic processor, central processing unit, image plotting device, color printer and wireless launcher, first image acquisition device connects central processing unit by image recognizer, second image acquisition device connects central processing unit by image mosaic processor, this central processing unit connects wireless launcher and image plotting device respectively, and this image plotting device connects color printer.Wireless launcher is cdma wireless transmitter module.First image acquisition device is high-definition camera.Second image acquisition device is high definition camera.The present invention utilizes image processing techniques to carry out site disposal and analysis to the scene of the accident photo that traffic police takes, thus accurately obtain physical dimension and the relative position of the object be positioned on same road plane, and then in the auxiliary of image information and the real-time mapping realizing scene of the accident relevant information under guiding.
Above to invention has been exemplary description; should be noted that; when not departing from core of the present invention, any simple distortion, amendment or other those skilled in the art can not spend the equivalent replacement of creative work all to fall into protection scope of the present invention.
