这次理想上架的L系列流媒体后视镜的主要特点为： 1.不涉及车辆外部设备改装合规上路，同样的车规级可靠性。 2.60度广角视野比普通内后视镜优秀。 这位群友明确认为很多改装用户实际体验下来会满意的，可以 解决用户开后排屏幕后无法观察车位的痛点，并且夜晚视野更清晰。 有预算额外买摄像头 模组，上嘉立创打板自己做。 中国国家法规中对于内部后视镜的要求驾驶员可以看到80米后20米宽的范 围假设后部有一个流媒体摄像头安装这个等效的摄像头的视角是30度。 3.对标24款MEGA,估计没有多少⼈体验过高亮清洗防眩､ 夜间夜视也超清晰 50Hz的刷新率对于高速的画面清晰流畅。 25款纯电和24款MEGA的最大区别就是60度广角升级为120度视野更宽。 关于200万像素 本身60度的流媒体后视镜已经比传统后视镜相比有碾压的⽤户体验了。 200万像素的摄像头传感器对应后视镜的显示器的像素是73万1920*384像素，考虑画面是长条状，截取画面的尺寸和显示的像素基本上可以映射。 简单说这个200万像素的摄像头像素是完全足够的，还多出很多像素得到的数据可以做环境光的感光计算以及画面质量的算法优化｡ 关于电子后视镜的清晰度 人眼到后视 ...

Core Viewpoint - The article discusses the development and features of the new streaming rearview mirror for the L9 model, highlighting its advanced technology and user-centric design [1][4]. Group 1: Product Features - The streaming rearview mirror has an 8-megapixel independent camera, providing high clarity with a resolution matching the central control screen and a PPI of 212 [1]. - It features a wide field of view of 120 degrees, allowing visibility of up to five lanes, significantly reducing blind spots compared to traditional mirrors [1]. - The mirror incorporates dual anti-glare technology, with the camera designed to prevent exposure and the LCD screen treated to minimize reflections [1]. Group 2: Development Process - Initial discussions questioned the necessity of a dedicated streaming rearview mirror due to the introduction of a 21-inch screen that could obstruct the physical mirror [1][2]. - The decision to proceed with the streaming mirror was influenced by the desire to maintain user habits and avoid a cramped driving experience when the second-row screen is deployed [1][2]. - The development faced challenges in sourcing video feeds, initially attempting to reuse the AD camera, which proved inadequate due to frame rate and color accuracy issues [2][3]. Group 3: Technical Challenges - Attempts to utilize the 360-degree surround view camera were also unsuccessful due to low resolution and significant distortion when adjusting the field of view [3]. - Ultimately, the decision was made to create a dedicated 8-megapixel camera with a 120-degree field of view, ensuring high quality and compliance with regulations [3][4]. - The design process included considerations for integrating the camera with the high-mounted brake light, leading to a decision to redesign the brake light for aesthetic and functional purposes [4]. Group 4: Market Positioning - The new streaming rearview mirror aims to enhance safety, comfort, convenience, and aesthetics, positioning the L9 as a leader in innovative automotive technology [4]. - The company plans to implement similar upgrades for the MEGA model, indicating a commitment to maintaining high standards across its product line [4].
