For the image capturing and processing, as well as Computer Vision algorithms, the open source OpenCV C++ library was used. 2-android-sdk missing build. 4. Road Lane Detection requires to detection of the path of self-driving cars and avoiding the risk of entering other lanes. Canny edge detection identifies an obstacle's edges through uncomplicated steps. I suggest beginning with manual thresholds, moving to histogram-based matching, and only using a full-fledged machine learning classifier (such as Obstacle detection is a critical component of modern vehicle safety systems. Brief steps involved in Road Lane Detection. If program detect some obstacle that train must stop, program gives you warning sign. Now I just have to find a similar discussion based on 'obstacle detection' JC. This impelementaion is based on Free Space Computation Using Stochastic Occupancy Grids and Dynamic Programming with some modifications.
