  • In order to improve the data collection efficiency of traffic accidents, the properties of traffic accidents and camera calibrated methods were analyzed, a extended-two-step camera calibrated method applied in traffic accident scene measurement was put forward. In the method, camera was calibrated according to linear model, then its nonlinear parameters were modified based on considering lens aberration, at last image was emendated according to new parameters, full camera calibrated steps and procedure were put forward, and an experiment of accident scene photogrammetry was done. The calibration results of the extended method and linear method show that the maximum values of absolute errors and relative errors are respectively 10.9 and 1.7%, and the least values of them reach respectively 4.1 and 1.0%. Obviously, the extended method has high precision and stability.
