System and method for providing traffic light ROI parameters to autonomous vehicle

A sequence of images and a vehicle location associated with each image are received at a traffic light ROI management system. At least one traffic light is detected in each image. An ECS traffic light ROI is defined for each image. The ECS traffic light ROI surrounds the detected traffic lights. A visual feature template is generated for each image. The visual feature template is based on the image ECS traffic light ROI. Each visual feature template is mapped to a vehicle location associated with the image on a high definition (HD) map. The HD map is sent to the autonomous vehicle to enable the autonomous vehicle to identify a real-time traffic light ROI in the real-time image according to a match between the first visual feature template and real-time visual features of the real-time image at a vehicle location associated with the first visual feature template. 在交通信号灯ROI管理系统处接收图像序列及与每幅图像相关联的车辆位置。在每幅图像中检测至少一个交通信号灯。为每幅图像定义ECS交通信号灯ROI。ECS交通信号灯ROI包围检测到的交通信号灯。为每幅图像生成视觉特征模板。视觉特征模板是基于图像的ECS交通信号灯ROI的。将每个视觉特征模板映射到高清晰
