Research on the Influencing Factors of 3D Camera Calculation Results

The 2024 version of the C-NCAP regulations has added a Farside test condition. To accurately obtain the head trajectory of the dummy during the collision experiment, this paper conducted an experiment on a certain vehicle model and used camera analysis software to study the effects of lens calibration parameters, different camera positions, and different focal lengths on the calculation results. The analysis results indicate that lens calibration can significantly improve the accuracy of calculation results; The camera calculation accuracy for the initial position of the dummy's head is highest when tilted; The lens with a focal length of 11.5mm has high and stable calculation accuracy.
