Survey on Vanishing Point Detection Method for General Road Region Identification

In today’s world automobile industries are coming out with so many new features in cars. Road infrastructures are also getting much better in all over the world. Due to this, the number of road accidents has increased and more number of people are dying in it. Researchers have tried to solve this problem by using virtual driver feature in the car. A computer vision based road detection and navigation system is put in the car that can help the driver about upcoming accident and rough driving. But the major problem in development of this type of system is identification of road using computer. And also detection of the unstructured roads or structured roads without remarkable boundaries and marking is a very difficult task for computer. For a given image of any road, that may difficult to identify clear edges or texture orientation or priori known color, is it possible for computer to find road? This paper gives answer to that question. First step is to find vanishing point, which uses Gabor filters to find texture orientation at each pixel and voting scheme is used to find vanishing point. Second step is to identify boundaries from this estimated vanishing point. This paper describes the considerable work that has been done towards vanishing point identification methods so that it can be used in real time for further applications.
