The invention provides a panoramic monitoring image generation method, a chip, a vehicle-mounted system and a vehicle. The method comprises the following steps that: a rasterization module reads vertex coordinates and texture coordinates of vertexes of each triangular patch from a memory, and projects each triangular patch into a panoramic monitoring image based on the vertex coordinates of each triangular patch, obtaining the texture coordinate of each pixel of the panoramic monitoring image based on the texture coordinate of the vertex of each triangular patch, and storing the texture coordinate of each pixel in a memory; the image digital signal processor reads texture coordinates of all pixels of the panoramic monitoring image from the memory, sampling is carried out from corresponding texture images according to the texture coordinates of all the pixels, texture values of all the pixels are obtained, the texture images are shot by a camera arranged on the vehicle, and the image digital signal processor is used for processing the panoramic monitoring image. The texture value corresponding to each pixel is used for outputting and displaying a panoramic monitoring image, the panoramic monitoring function of the vehicle is realized in a heterogeneous mode, and the performance pressure of the GPU is reduced.

    本申请提供一种全景监控图像的生成方法、芯片、车载系统及车辆。该方法包括:光栅化模块从存储器中读取各三角形面片的顶点坐标和顶点的纹理坐标,基于各三角形面片的顶点坐标将各三角形面片投影到全景监控图像中,以基于各三角形面片的顶点的纹理坐标得到全景监控图像的各像素的纹理坐标,将各像素的纹理坐标存储至存储器中;图像数字信号处理器从存储器中读取全景监控图像的各像素的纹理坐标,按照各像素的纹理坐标从相应的纹理图像中进行采样,得到各像素的纹理值,纹理图像由设置于车辆上的摄像头拍摄,各像素对应的纹理值用于输出显示全景监控图像,通过异构方式实现车辆的全景监控功能,降低GPU的性能压力。
