Study of method on parking guidance based on video

Aiming at the problem that there is an urgent need for an intelligent and efficient parking management system, this paper proposes a kind of design to detect the free parking spaces. The design combines the License Plate detection algorithm with the Gray Level Changes detection algorithm in fixed parking spaces area. It optimizes this algorithm by continuously doing simulation experiments. The paper also uses an improved Dijkstra algorithm to determine the shortest path when searching for the parking space. Experimental results indicate that the system can serve as the basis for constructing an intelligent parking guidance system, which has good stability.
