5.5 Function Overview
5.5功能概述

The SVS system picks up the view around the body through four cameras and the controller seamlessly stitches the images from the four cameras to form a 360° panorama, displaying a 360° image of the surroundings of the body similar to an image taken from the sky.
SVS系统通过四个摄像头拾取身体周围的视图，控制器将四个摄像头的图像无缝拼接，形成360°全景，显示身体周围的360°图像，类似于从天空拍摄的图像。

1.如果启用高速逻辑，则

Case 1: Vehicle Speed<= SVS_Speed_Thold then it will open front view based on default setting .
情况1：车速<= SVS_Speed_Thold，则将根据默认设置打开前视图。

Case 2: Vehicle Speed > SVS_Speed_Thold then it will open rear view based on default setting .
情况2：车速> SVS_Speed_Thold，则将根据默认设置打开后视图。

2. if high speed logic is disabled then
2.如果禁用高速逻辑，则

Case 1: Vehicle Speed<= SVS_Speed_Thold then it will open front view based on default setting .
情况1：车速<= SVS_Speed_Thold，则将根据默认设置打开前视图。

Case 2: Vehicle Speed > SVS_Speed_Thold then SVS screen will not open

Remarks:
备注：

1.The detection performance of the side sensor is shown in the figure below: the detection range of the ultrasonic sensor has a 20cm blind area, so when the obstacle/curb is in the color filling area, the side sensor can detect the obstacle/curb and output the distance from the obstacle/curb; when the obstacle/curb is outside the color filling area, the side sensor cannot detect the obstacle/curb.
1.侧面传感器的检测性能如下图所示：超声波传感器的检测范围有20 cm的盲区，所以当障碍物/路缘石在填色区域内时，侧面传感器可以检测到障碍物/路缘石，并输出与障碍物/路缘石的距离;当障碍物/路缘石在填色区域外时，侧面传感器无法检测到障碍物/路缘石。

2.If the height of obstacles/curb or curbs is less than 20cm, the ultrasonic sensor cannot detect them.
2.如果障碍物/路缘石或路缘石的高度小于20 cm，超声波传感器无法检测到它们。
