Safety - Cameras



Suppliers are currently having at least as much trouble as car manufacturers. A feverish competition has broken out among them as to which of them will first seize a particular e-mobility theme cluster. Certain specializations are already visible. Continental has taken care of cameras, but radar sensors are also produced in such quantities that they may soon exceed the 100 million mark (bottom picture).


Do you still have the overview, where everywhere in the car cameras are usefully applicable. It all started with the view to the rear. There can meanwhile also be two of them, if e.g. a trailer coupling is present. Then the view through the windscreen at the front, besides traffic sign recognition and accident avoidance also helpful for partial shutdowns with matrix light. Next is the replacement of the rear-view mirrors (picture below). For large vehicles, a lateral overview is important, e.g. when turning off to protect cyclists.


Drivers of off-road vehicles may also want to know what is being to come under their wheels or what is threatening their underbody in general. At Continental, they call this the transparent engine compartment. With so much information at once, computer analysis is particularly important. Artificial intelligence is perhaps said too much, but first of all from pictures e.g. people are to interpret what they are doing or perhaps still doing.

The software for this is probably integrated into the camera behind the interior mirror, which is therefore hardly larger than with previous cameras with significantly lower resolutions and a lower viewing angle. State of the art, from 2020 probably in series production for the first time, 2.5 megapixels, 8 are in preparation. For normal drivers, the 360° view is probably the most spectacular. Here, the quite wide-angle images of the four cameras are first rectified and then assembled. If you hold your hand in front of one of them, you can observe its part in the overall picture.


Only the vehicle is truly three-dimensional. It is added in the middle of this arrangement. The wide-angle images are projected onto a large, bowl-shaped surface around the car, which is a bit 3D. pretended. For off-road vehicles the underground under the car will be added in the future (picture above). What is important about the software is that it can also become active if it detects a certain danger potential. Examples would be the correction of the tracking and the emergency brake assistant.


So far so good. However, the special feature of Continental's software seems to be that it can evaluate the images of several cameras whose images have been linked in this way. One announces there, for example, the vehicles will in future be able to be braked automatically even when reversing. Imagine camera systems equipped with this technology, which also replace the rear-view mirror and thus also can better warn of incidents that, for example, make a lane change appear inadvisable at the moment. 12/19
