Virtual Surround View (VSV) Parking
The VSV function, available on compatible ATOTO S8 (Gen2) Android car stereos, uses the AC-HD03LR camera to create a simulated bird's-eye view of your vehicle's surroundings. This feature significantly enhances parking safety by providing a comprehensive overhead perspective.
- To activate VSV, ensure your ATOTO S8 (Gen2) head unit has the necessary firmware and image stitching algorithm.
- The system will process the camera's 180-degree input to generate a dynamic, simulated 360-degree view on your car stereo screen.
- Your vehicle's position and surrounding obstacles will be clearly distinguished on the display.
