Patent Images
1. A system implemented in a vehicle to detect a lead vehicle comprising:
- a camera which captures an image of the rear of the lead vehicle;
an image processing system that receives image data from the camera, the image processing system being implemented with an algorithm that includes a preprocessing layer, an image segmentation layer, and a detection layer to analyze the image data to determine the relative distance between the vehicle and the lead vehicle;
wherein the preprocessing layer reduces noise in the image data and generates vertical and horizontal edge maps; and
wherein the preprocessing layer includes a Gausses filter and a sharpening filter.
