This paper presents a new approach of a path planing algorithm applied in an indoor environment. Path planning or motion planning is an essential part of navigating mobile agents. The goal of path planning is to specify a collision-free trajectory between the start state and the goal state for a mobile agent. The estimation of the absolute position inside the testing environment is performed based on visual ground patterns and image processing technique. A graph search algorithm, A*, find the shortest path considering not only a distance cost but also an additional cost function for controlling the safety. An illustrative example of a quadrotor is used to evaluate the robustness of algorithm.
