The digital camera is used for taking photos and shooting on the accident scene, the photos and the videos are sent to the central processor for image processing, the graphic process software has digital watermark encryption technology that adds marks on original photos. Planar graphs that conform to regulations are drawn according to the graphs. The utility model has the advantages of high degree of precision and automation, easy to be manufactured, easy to be operated, high working efficiency and easy to be supervised and managed.
Description
One, technical field
The utility model relates to photogrammetric and computer vision, is a kind of photogrammetric scene of a traffic accident of surveying of utilizing, and draws measurement, the rendering apparatus of scene photo.
Two, background technology
At present, carry out scene of the accident exploration in the domestic relevant photogrammetric technology of being understood of using, and go out in the relevant report of scene photo, employed technology all is to use two cameras to measure, and all is to use vehicle to measure and draw as important assistant tool.Technically, its drawback is: measuring accuracy is lower, and can't fully guarantee the authenticity and the validity of the scene photo of drawing; From preparation, when being to measure, its drawback must be equipped with special-purpose vehicle through repacking, not only use inconvenience, and cost is very high.
Three, summary of the invention
The purpose of this utility model is to overcome the shortcoming of above-mentioned prior art, and a kind of measuring accuracy height is provided, and cost is low, true, objective, the reliable scene of a traffic accident surveying device of data.
For achieving the above object, the solution that the utility model adopts is: comprise casing, be characterized in, be provided with central processing unit, digital camera, power supply and object of reference template in the casing, central processing unit and power supply link, digital camera is connected with central processing unit by USB interface, and central processing unit contains digital watermarking encrypted image process software.
Another characteristics of the present utility model are: also be provided with the printer that links with central processing unit in the casing.
The utility model uses one camera, utilizes technology such as coupling in the computer vision, conversion, correction to reach the purpose of position, range observation, its measuring accuracy height; And the authenticity and the reliability of accident image scene have been protected in the application of anti-tamper digital watermarking effectively; thereby make result have certain legal effect; and automaticity height; easy operating; it is reusable to be convenient to grasp, high efficiency, data; be convenient to supervision and management, make every effort to reduce interference from human factor from start to finish, reach objective and fair, purpose with low cost.
Four, description of drawings
Fig. 1 is a connection block diagram of the present utility model;
Fig. 2 is the schematic diagram of the utility model housing 1 and template 5.
Five, embodiment
Below in conjunction with accompanying drawing structural principle of the present utility model and principle of work are described in further detail.
Referring to Fig. 1,2, the utility model is measured the scene of a traffic accident and draw the needed central processing unit 2 of planimetric map, digital camera 3, power supply 4, object of reference template 5 and printer 6 and is integrated in the casing 1, central processing unit 2 links with power supply 4, digital camera 3 links by USB interface and central processing unit 2, and digital camera 3 is used for carrying out the photograph taking of the scene of the accident; Also be provided with object of reference template 5 for shooting in the casing 1, object of reference template 5 is used for using as the object of reference of measuring distance, measured line segment must with object of reference template 5 in same plane; And central processing unit 2 is used to receive and handle the photo after the shooting, digital camera 3 is imported central processing unit 2 with photo and is carried out Flame Image Process, central processing unit 2 contains " digital watermarking encryption " image processing software, on-the-spot original image is encrypted, image processing software is according to encrypted picture, form accident situ map, and calculate after the actual value of testing distance its Automatic Logos on accident situ map, simultaneously measured result is marked on the realistic picture of drawing." digital watermarking encryption " image processing software is a new technology in the secret and safe field now, and it joins in the picture that needs protection after with the certain computing of information via.The adding of these information visually can not influence any composition of protected picture, has only through after the inverse operation, information hiding in this picture could be extracted.Also be provided with the printer 5 that links with central processing unit 1 in the casing 1, printer links with power supply 4 again, and realistic picture the most up to specification is printed by printer 6.
Concrete running program is as follows:
Every group that supposes each scene of the accident processing comprises 2 people at least, is respectively first, second.
1. behind the arrival scene of the accident, first is responsible for the image scene collection, and content comprises: utilize digital camera 3 to take the above panoramic pictures of at least two width of cloth; Comprise at least one width of cloth of the local picture in each testing distance or position; In shooting process, be placed in the same plane with reference to thing template 5 and measured line segment;
2. second starts the utility model, concrete steps: first energized 4 in first work, open central processing unit 2, enter system interface, set up a newly built construction, select to draw accident situ map, add corresponding road shape, vehicle symbol, determine the orientation, define position to be measured and distance, and the corresponding document information of typing, as time, place, litigant's name and identification card number, driving license, and when thing vehicle number, vehicle etc.;
3. work as first and finish image acquisition, USB interface by central processing unit 2, view data is imported central processing unit 2, form accident situ map, second then is responsible for setting up the corresponding of testing distance and real pictures in the accident situ map, finish after the coupling of corresponding point, then select to calculate, to calculate the actual value of testing distance, and with testing distance line segment Automatic Logos on accident situ map, simultaneously measured result is marked on the realistic picture of the scene of the accident, can put on record by related personnel's signature with scene of the accident realistic picture by printer 6 outputs.
