How the multi-camera system works
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.
A new technical feature of the multi-camera system is the seamless, distortion-free stitching together of the camera images in real-time. Depending on the selected perspective, the system dynamically adjusts the borders of the images. The result is a homogeneous picture with no distracting frames or overlaps, and object visibility is always at an optimum.
