摘　　要：针对车载360环视应用场景对实时性的较高要求,提出了一种基于嵌入式设备的高效环视融合方案。该方案结合了环视图像矫正、俯视变换和环视融合三个步骤,建立了采集到的原始图像与最终环视图像之间的像素查找关系,并在多种车载嵌入式平台上进行了验证。结果表明:该方法相比传统方法能够有效降低图像处理的计算量,从而大幅降低嵌入式设备的环视融合延时,优化后平均每帧处理的时间可缩短至优化前的二分之一以下。Aiming at the high real-time requirements of vehicle-mounted 360-degree surround view applications, an efficient surround view fusion scheme based on embedded devices is proposed. The scheme combines three steps: Surround image correction, top-view transformation, and surround view fusion, establishing a pixel lookup relationship between the collected raw images and the final surround view images, and verifying it on multiple vehicle-mounted embedded platforms. The results show that compared with traditional methods, this method can effectively reduce the computational burden of image processing, thus significantly reducing the surround view fusion delay of embedded devices. The average processing time per frame after optimization can be shortened to less than half of the original processing time.
