A Monocular Camera Calibration Method for Extrinsic Parameters under Traffic Environment

According to the characteristics of traffic camera calibration, a method for extrinsic parameters calibration is proposed based on four control points. The initial value of the iterations is solved by pinhole camera model equations. Then, the constraints of the orthogonal matrix are added to amend the result using generalized least squares (GLS) and the Newton-Raphson method. Measured on a simulated setting, tests showed that this method -- compared with the traditional method and considering no nonlinear constraints -- uses less control points to achieve higher calibration accuracy and reduces the outdoor workload.
