The invention relates to the technical field of radar imaging, in particular to an automobile radar imaging system, which is characterized in that hardware such as a camera is arranged, an image is reasonably connected and controlled with a radar processing unit and an ultrasonic radar module, and pictures shot by the camera are spliced and processed. The image processing module establishes a coordinate system, a focal length, a distortion coefficient and external parameters: a translation matrix and a rotation matrix are used for representing the relative position between the two cameras, and the image processing module processes the initial position information and then sends the initial position information to the processor; the processor adopts binocular stereo vision to obtain position information of an object in a complete image, the position information is transmitted to a computer, and each object model of the image is reconstructed by software, so that a three-dimensional digital model is established, and an accurate model effect is achieved.
本发明涉及雷达成像技术领域,具体涉及一种汽车雷达成像系统,通过设置摄像头等硬件,将图像与雷达处理单元与超声波雷达模块之间进行合理的连接与控制,将摄像头所拍摄的画面进行拼接与处理,能够将画面在显示器上进行清晰的展示,图像处理模块建立坐标系,焦距、畸变系数,外参数:用一个平移矩阵和一个旋转矩阵来表示两相机之间的相对位置,图像处理模块将初步位置信息处理后发送给处理器,处理器采用双目立体视觉获取完整的图像中物体的位置信息,传输到电脑上,由软件重建出图像各物体模型,从而具有建立三维数字化模型,得到精确的模型效果。
