In a specific embodiment, the system of described comprehensive reduction road accident image can be shown on other equipment through the information that influences that a video output module 7 will obtain and generate.
As shown in Figure 1, the present invention provides a kind of comprehensive reduction road accident image method, may further comprise the steps:
During the S100 vehicle launch, car body is carried out whole detection, obtain the initial three-dimensional appearance data of car body; Described initial three-dimensional appearance data comprise following data: the first overall appearance image data of the initial deformation data of car body and car body.
When automobile starting; This system also starts voluntarily, and system is through adopting the principle of space exploration things such as ultrasound wave/radar, to the outward appearance of automobile; Comprise that top and chassis carry out that an omnibearing deformation is surveyed and scanning, and get up the initial deformation data storing of scanning car load.Meanwhile start camera; Take and store the formation first overall appearance image data to the overall appearance of car (comprising roof and chassis); Generate initial three-dimensional appearance data through the reorganization of image that camera is taken and the processing of deformation data; At first restore the three-dimensional appearance picture A of this automobile before setting out, and all mark out the deformation data of car outward appearance.
Said deformation data are through space instruments such as ultrasound wave/radars, and the outward appearance of car is carried out entire scan, thereby draw the detailed spatial data of car load.These deformation data combine camera to photograph the processing of car load picture and image algorithm again, can draw the tri-dimensional picture of the present truth of automobile.
In the S110 vehicle ' process, be the center, obtain the surrounding enviroment three-dimensional data of car body with the car body;
Wherein, utilize camera road pavement situation to take, utilize velocity radar that the speed of a motor vehicle and the spacing of nearby vehicle are monitored simultaneously.Data such as the speed of a motor vehicle that image that system photographs camera and detections of radar arrive, spacing, through the processing of image algorithm, Intelligent Recognition and combination, restoring with this car is travel situations and the video image of road conditions of vehicle of the three-dimensional at center.
S120 detects when having an accident, and car body is carried out whole detection, obtains the accident conditions three-dimensional appearance data of car body, and the surrounding enviroment three-dimensional data of mark current vehicles;
Compare analysis according to initial three-dimensional appearance data, surrounding enviroment three-dimensional data and accident conditions three-dimensional appearance data, generate the image of reduction road accident.
Wherein, If traffic accident situation such as the friction of this car generation vehicle or collisions, the strength sensor on the car has been sensed, and carries out the judgement that accident takes place through detecting the vehicle stressing conditions; Said being judged as: the size through detecting the power of external action on car body is judged; If acting force greater than preset threshold value, then is judged as have an accident, otherwise be the accident free generation.Note exterior object to the impulsive force that receives of this car then; The intellectual analysis main frame just starts the instrument that camera and ultrasound wave/radar etc. can the space exploration things then; As step S100 is said; Note the second overall appearance image data of the second deformation data and car body, and comprehensive accident conditions three-dimensional appearance data, and the outward appearance deformation situation of automobile is showed through tri-dimensional picture B.Tri-dimensional picture A when smart host combines automobile starting then; Tri-dimensional picture B during with traffic accident also has the automobile 3 D video of embodiment two image that goes, through the processing and the Intelligent Recognition of image algorithm; Restore this car when getting into an accident; The three-dimensional pavement situation of this car and nearby vehicle/object, the speed of a motor vehicle of each vehicle, spacing, and also be labeled in impulsive force and the deformation situation that vehicle receives on the image simultaneously.
Comparing analysis through initial three-dimensional appearance data, surrounding enviroment three-dimensional data and accident conditions three-dimensional appearance data mainly is to come image and data are put in order, contrast, extract, analyze, synthesized through image algorithm; Generate video playback form commonly used at last, carry out video output.
The initial deformation data are record automobile space situation before setting out, and comprise the overall appearance of automobile and the depression situation of automobile, and the second deformation data are to have write down the space situation of automobile when accident takes place.Through analysis to this two picture groups sheet, to the damaged condition of vehicle, also be the intellectual analysis unit when clearly understanding accident takes place, to analysis, reorganization, the merging of scene of the accident video, sufficient algorithm data foundation is provided.
General vehicle running recording instrument device can only write down other traveling state of vehicle except that this car, like a shelf of propping up camera, is the situation of taking less than shelf itself.And the camera on the road surface also just photographs the situation on road surface, not very detailed data.Through the present invention, just can clearly recognize Ben Che and the situation of other vehicle/objects on the road surface, and the data of each item.Method of the present invention, like being to be the center with this car, the situation and each association of other vehicle/objects on this car and the road surface can monitored and measure to the intelligent monitoring pick-up head that this car of follower moves in all directions.
