The invention relates to the technical field of vehicle positioning systems, and discloses a vehicle visual positioning system based on a specific scene. The system comprises a parking lot, a vehicledetection unit, a scene database, an image acquisition unit and a server side. The server side is provided with a target parking space configuration module, a specific identification module and a posecalculation module; when the vehicle detection unit detects that the vehicle is driven to the entrance of the parking lot, the target parking space configuration module configures a target parking space for the vehicle; the server side obtains to-be-compared image information from the image acquisition unit and determines corresponding reference image information; the pose calculation module calculates three-dimensional position information and relative pose information of the vehicle through a PNP pose algorithm, calculates position information and orientation information of the vehicle relative to a geodetic coordinate system according to the relative pose information of the vehicle, generates actual position information according to the position information and the orientation information, and sends the actual position information to a vehicle end.
本发明涉及车辆定位系统技术领域,公开了一种基于特定场景的车辆视觉定位系统,包括:停车场、车辆检测单元、场景数据库、图像采集单元以及服务器端,服务器端配置有目标车位配置模块、特定识别模块以及位姿计算模块,当车辆检测单元检测到车辆驶入至停车场的入口处时,目标车位配置模块车辆配置目标车位;服务器端获取来自图像采集单元的待比对图像信息,确定对应的基准图像信息;位姿计算模块通过PNP位姿算法求出车辆的三维位置信息和相对姿态信息,根据车辆的相对姿态信息计算得到车辆相对于大地坐标系的位置信息与朝向信息,根据位置信息和朝向信息生成实际位置信息,并将实际位置信息发送至车辆端。
