摘要：【中文】本发明公开了一种高性能的车辆动态三维建模与轨迹实时渲染方法及装置，先截取视频画面为图片，记录每张图片中车辆的屏幕坐标和车辆类型，并存储在txt文件中；预先设置好的道路模型以及车辆模型导入到MapGIS数据库中；在MapGIS桌面软件里构建三维场景，添加导入后的道路模型，并保存为地图文档；手动采集视频截图和三维场景中的四个控制点对；调用桌面二次开发接口在场景中预先添加不同类型的车辆模型，不设置模型的位置和角度信息，显示状态设为不可见；设置一定时间间隔顺序读取txt文件，根据坐标转换方法计算出车辆的三维坐标，根据车头车尾坐标，计算出车辆的角度，动态更新场景中预先添加的小车坐标、行驶角度，并设置模型的显示状态设为可见。 【EN】The invention discloses a high-performance vehicle dynamic three-dimensional modeling and track real-time rendering method and a device, wherein a video picture is firstly captured as a picture, the screen coordinate and the vehicle type of a vehicle in each picture are recorded and stored in a txt file; importing a preset road model and a preset vehicle model into a MapGIS database; constructing a three-dimensional scene in the MapGIS desktop software, adding the imported road model, and storing the road model as a map document; manually collecting four control point pairs in a video screenshot and a three-dimensional scene; calling a desktop secondary development interface to add different types of vehicle models in a scene in advance, setting no position and angle information of the models, and setting the display state to be invisible; setting a certain time interval to sequentially read the txt file, calculating the three-dimensional coordinates of the vehicle according to a coordinate conversion method, calculating the angle of the vehicle according to the coordinates of the head and the tail of the vehicle, dynamically updating the coordinates and the running angle of the trolley added in advance in the scene, and setting the display state of the model to be visible.
