Paper Abstract

Vanishing point is an important concept in the sensors’ self-calibration method. For traditional self-calibration method based on vanishing point, it's computationally intensive, real-time not high and noise sensitive. A novel method of sensor self-calibration based on rectangular vanishing point characteristics is proposed to solve all these problems mentioned above. Firstly, four template images are captured from different angles and locations. Subsequently, the vanishing points are calculated by using the coordinates of the four vertices in rectangle. Finally, the novel sensor parameter equation is proposed by using the geometry properties of rectangle and the vanishing points. Some numerical simulations are made to test the validity and robustness of the proposed algorithm.
