Algorithm to extend detecting range for AVM stop line detection

Abstract

A system and method on a vehicle for providing extended detection range of a stop line on a roadway. The system and method includes a front view camera on the vehicle that provides images of the roadway in front of the vehicle and a controller that receives images from the front view camera. The controller is programmed to extract an upper portion of a front view image that is remapped onto an extended bird's eye view image such that the detection range of the stop line is detected.

[0001] Cross References to Related Applications [0002] This application claims the benefit of the priority date of US Provisional Patent Application Serial No. 62 / 027,953, entitled "Algorithm for Extending Detection Range for AVM Stop Line Detection," filed July 23, 2014. technical field [0003] The present invention relates generally to extended stop line detection ranges in vehicles, and more particularly to systems and methods for extracting the upper portion of a forward view image and remapping the upper portion of the image to an extended bird's eye view image. Background technique [0004] Modern vehicles are becoming more and more autonomous, that is, modern vehicles are able to provide driving control with less intervention from the driver. Cruise control systems have been on vehicles for many years, where the vehicle operator can set a specific speed for the vehicle, and the vehicle will maintain that speed without the driver operating the throttle.

Problems solved by technology

For example, known edge detectors such as Sobel and Canny edge detection may be inaccurate when detecting candidate lines against dirt, lighting changes, and other noise, thereby creating a security risk

Furthermore, algorithms are known to be complex with or without associated lane markings
