The invention is suitable for the technical field of intelligent automobiles, and provides an intelligent adjusting method and system for the irradiation angle and luminous flux of a headlamp of a motor vehicle, and the method comprises the following steps: obtaining the human eye real coordinates of a driver of an opposite coming vehicle during meeting through a vehicle-mounted front-facing camera based on a machine vision technology, and calculating the sight height and the meeting distance; the sight line height and the meeting distance are calculated according to the real coordinates of the eyes of the driver, the optimal irradiation deflection angle of the headlamp is calculated, and the irradiation angle of the headlamp is adjusted; and when the irradiation deflection angle of the headlight is adjusted to the minimum angle, the luminous flux is linearly adjusted according to the meeting distance. According to the method, the optimal irradiation deflection angle and luminous flux of the headlamp are calculated by using an intelligent control algorithm, manual operation of a driver is not needed, and the adjusting speed and precision are remarkably improved. And according to an output result of an intelligent control algorithm, the irradiation angle and the luminous flux of the headlamp can be accurately adjusted, the risk that eyes of a driver on the opposite side are directly irradiated is effectively avoided, and the driving safety is ensured.
