3D panoramic survey and demonstration demonstration system at the scene of a traffic accidentIt is made up of 3D digital graphics software and 360-deg; Beijing Jinvision and Technology Co., Ltd. is based on graphic images and 3D simulation field of cutting-edge scientific research results, and combined with many years of traffic accident processing department research data customized development solutions.
The panoramic shooting system equipped with the 3D panoramic measurement and analysis demonstration system at the scene of the traffic accident consists of a high-end SLR digital camera, high-precision fisheye lens and fully automatic shooting head, which can take a complete set of panoramic pictures of the scene in one minute, and stitch and blend in a fully automatic way without human intervention in the stitching process. To achieve the goal of rapid panoramic reconstruction of the traffic accident scene.
In the traditional workflow, due to human, weather and other external factors interference, the accident scene is easy to be damaged and interfered with in a short period of time. In view of the special nature of the accident scene, fast, complete and accurate preservation of the accident scene, the scene of the traffic accident can not be as long as the scene of the criminal case to retain. Traffic police in the recording of the scene of the accident, mostly through sLR digital cameras, intuitive to the scene of the accident to carry out a large number of physical evidence and scene shooting, in the post-analysis of the accident scene due to the large number of photos, it is difficult to establish the image of the accident site awareness, and may even miss some key information. With the help of the 360-deg, the fully automatic robot shooting system will save the true traffic accident scene complete, and you can take screenshots, measure and analyze the panorama of the traffic accident scene at any time after the evacuation of the traffic accident site.
On-site collection of physical evidence images and multi-scene hot spot addition
In the real traffic accident scene need to take a large number of scene details images (vehicle marks, road marks, scene environment, bodies, debris and debris on the scene, blood, etc.). But a large number of on-site images can easily confuse physical evidence with technicians, which can have a significant impact on future case analysis. The hot spot add-on feature of the 3D panoramic measurement and analysis demonstration system for traffic accident sites can be hyperlinked to the scene panorama and 3D reconstruction site, and you can double-click the mouse to zoom in and highlight the detail image, as well as support for text, pictures, audio, and video to add a variety of types of files. At the same time, you can create folders to organize the classification of physical evidence images, rename and delete detailed photo resources, which is of great help to the analysis of the accident process.
At the same time in the handling of multiple traffic accident scenes, through the hot jump way of multiple traffic accident scene panorama connected, in addition, can also establish a panorama and scene orientation map, scene three-dimensional map between the location relationship, with a more three-dimensional image of the scene of traffic accidents.
3D model and real-life image augmented reality fusion
The unique augmented reality capabilities of the 3D panoramic measurement and demonstration system at the scene of a traffic accident can drag the 3D model (people, roads, vehicles, buildings, etc.) to the real scene of 360-deg, and the panoramic image can be used to blend the 3D model with the panoramic image through augmented reality technology. Field simulation of the accident process in the 360-deg/panoramic image helps field surveyors analyze the accident process more accurately.
Massive library of professional 3D models
The 3D panoramic measurement and demonstration system of traffic accident scene relies on the research data of the traffic accident treatment department, as well as its own virtual reality and 3D simulation technology, has established a huge library of professional model resources, with more than 20,000 kinds of 3D models. These include three-dimensional models of people, vehicles, roads, buildings, public facilities, etc., which can fully meet the needs of three-dimensional reconstruction of traffic accident sites.
With a vast library of 3D models and simple drag and drop operations, the 3D Panorama Measurement Analysis Demonstration System for Traffic Accident Sites creates a 3D reconstruction site site in minutes that is very close to a real-world scene.
Quickly customize site 3D rebuilds
The 3D panoramic survey and demonstration system for traffic accident sites has a powerful rapid modeling capability that allows users to reconstruct the traffic accident site in minutes through simple drag and drawing, depending on the needs of the different field environment (intersections, neighborhoods, parks, roads, etc.).
The traditional method of restoring traffic accidents, technicians can only be achieved by drawing and text description, but this method is not intuitive, and can not fully display the details, which will be biased in the handling of the accident, quickly customize the scene of 3D reconstruction function subverts the traffic accident scene traditional hand drawing or flat drawing way, On the basis of flat drawing, the scene 3D stereoscopic map is immediately generated, and the scene of traffic accident is restored very close to the real by the precise ruler and scale, as well as the massive library of 3D model resources.
The 3D panoramic measurement and analysis demonstration system for traffic accidents has a powerful 3D animation engine built into the system, which can create and edit models such as vehicles and characters. Rich 3D model resource library can really restore a variety of road environment, realistic character action resource library and vehicle animation, can be extremely realistic to restore the occurrence of the accident process. Unique key frame animation creation method, can create a variety of simulation animation in a short period of time, such as a human-car collision, vehicle tail-end, scraping, after-crash flip and other accident process, to help traffic accident handlers to restore and analyze the case.
For common vehicle accidents, fire site simulation recovery analysis system can also create process animation simulations. The impact, movement, flipping and other effects of the vehicle accident can also be created, and then according to the occurrence of the vehicle accident process, as well as the process of fire formation quickly create accident simulation animation.
Traffic accident site data measurement, dimensioning and brush ingress
In the reconstructed 3D panoramic scene, you can directly measure the distance between any two points in the field image, and you can create dimensions in the 3D scene based on the actual field forensic data, add the known data to the 3D field layout, and the brush label function can create instant labels and circle points anywhere in the image.
This function is particularly important for drawing the scene image of traffic accident, which avoids the problem of irreversible measurement data missing from the scene, breaks through the perspective limit of the traditional floor plan, and also adds real field data and instant brush labeling, so that the whole three-dimensional reconstruction of the traffic accident site information more rich and specific.
In the reconstructed three-dimensional scene, according to the actual on-site road conditions by drawing roads, drawing fences to restore the real scene to meet the needs of different road surfaces, while the new version of the software added the human car separation, door switches and car and door separation effect, so that the reduction effect is more real and accurate.
In order to ensure the security of the accident site data, the accident site 3D reconstruction and animation files in encrypted. JSH format save. At the same time can also output a common executable. EXE files for playback browsing. The new 3D accident scene and accident simulation reporting method can be presented with multi-directional perspective and 3D animation presentation, completely replacing the traditional PPT reporting, so that traffic accident scene has a stronger sense of generation and accuracy. Accident management department will be these intuitive accident scene and accident process issued to the community in a timely manner, will play a role in guiding public opinion, to eliminate the community's doubts about the accident, play a role in controlling public opinion, to correct audio-visual, social stability. The exE file exported at the same time allows for accurate measurementof of the distance between any two points.
