Motor vehicle headlamp luminous intensity distribution property self-adaption detection method based on camera method

The invention discloses a motor vehicle headlamp luminous intensity distribution property self-adaption detection method based on camera method, which comprises the following steps of: performing quasi-positioning on far and near illumination; acquiring the light type of lower beams, acquiring the light type of upper beams; digitally processing light type data of upper and lower beams; judging whether the data meets a certain requirement or not; storing coordinates of movement compared with an initial position; storing images and the data; printing and displaying data; carrying out self-adaption sampling region adjustment; judging whether the sampling region surpasses a certain range or not; determining whether a product is qualified, and the like. By adopting the motor vehicle headlamp luminous intensity distribution property self-adaption detection method based on camera method, all possible measurement can be realized by performing one-step collimation of the motor vehicle headlamp luminous intensity distribution property self-adaption detection system in the prior art; and if a lamp at a collimation position is unqualified, other positions where the lamp is qualified can be searched through software without collimating or testing once again, so that the detection testing time can be shortened, and the possibility of passed inspection and the authority and accuracy of detection can be increased.
