Parking is among the activities most likely to be associated with stress and accidents. As every centimeter counts when parking, it is usually better to see than to hear. The second generation of the multi-camera system gives drivers a 360 degree surround view to ensure easy, safe and comfortable parking and maneuvering.

How the multi-camera system works.
The Bosch multi-camera system consists of four near-range cameras. One faces forward, another backward, while the two side cameras are integrated into the exterior rear-view mirrors. With an aperture of 190 degrees each, they capture the vehicle’s entire surroundings. The system also includes an ECU, which merges the camera images to form a 360 degree view and – if desired – combines them with distance information from ultrasonic sensors.
Using this data, Bosch generates a dynamic, 3D wireframe around the virtual vehicle model; the shape of that frame is adjusted to match the changing surroundings. Bosch takes the real-time images from the near-range cameras and projects them onto the wireframe. In contrast to 2D systems, this method allows objects that rise up to be represented more realistically.
The 3D surround view of the multi-camera system sets new standards and offers several advantages – thanks to a highly sophisticated video-based object detection. The 360 degree surround view and the automatic, real-time tracking shot always provide the driver seamlessly with the best perspective. In addition, the multi-camera system generates a realistic, animated 3D vehicle model that provides the driver with an impressive, detailed picture of the vehicle’s environment. Moreover, the system generates a realistic, animated 3D vehicle model, which gives an impressive, detailed image of the vehicle’s surrounding to the driver. The 3D visualization automatically adapts while maneuvering according to an environment model based on sensor data fusion to provide the best view on critical situations. This makes automated parking and parking assist functions easier and safer.
The modular approach of the new generation of the multi-camera system covers various customer requirements and performance levels with a control unit, near-range cameras with a resolution of 1 or 2 megapixels and optionally ultrasonic sensors. Lite variants of the system integrate two or four cameras depending on the camera resolution.
Automated and assisted parking functions can be realized robustly with the help of the multi-camera system as sensor data fusion increases the understanding of the vehicle’s surrounding and thus improves parking functions like the (remote) park assist or the home zone park assist. When it comes to parking and maneuvering assistance, the multi-camera system can also provide trailer assistance to the driver: It eases coupling the trailer by providing a specific view on the tow coupling and supports the driver when reversing with the trailer by taking over lateral control of the vehicle.
