2012 GMC Terrain Introducing First Single-Camera Crash Prevention System [Video]
GM is now addressing that issue with the 2012 GMC Terrain, which introduces a crash avoidance system that relies on a single camera instead of the usual camera-radar-laser army of system used until now, thus managing to cost only $295 (EUR220 at the current exchange rate).
The system uses a camera the lane departure and collision warning features, relying on image processing algorithm to estimate what is going to happen.
“The forward collision warning software examines each frame captured by the camera – about 14 frames per second – searching for shapes characteristic of vehicles. Detected vehicles are then checked over successive frames for changes in size for calculating time-to-collision. The system also uses speed, directional change, and how the accelerator and brake pedal have been applied to determine when to alert the driver,” a company statement reads, explaining how the system works.
“In order to operate in varying visibility conditions, the system combines four separate exposures to create each high-resolution image for analysis. Night time target recognition is also enhanced by looking for pairs of lights moving together that indicate taillights.”
