According to the structure, the automobile headlamp is arranged in front of an automobile, when the automobile runs, the spotlight assembly 1 of the automobile headlamp projects infrared stripes to a running road surface, when an object appears on the running road surface, the infrared stripes can irradiate the surface of the object, the irradiated object can diffusely reflect the infrared stripes, and the infrared stripes can be modulated along with the change of the outline of the object, so that the shape of the infrared stripes is distorted and deformed, and the distorted stripes corresponding to the outline of the object are formed. Meanwhile, the camera 2 of the automobile headlamp can shoot the shape of the real-time distorted stripe projected on an object on a driving road surface, and then the image processor 3 calculates the shape of the distorted stripe, so that the image information of the distorted stripe can be obtained, and the image information can calculate the information such as the undulation and the pothole of the road surface, the distance, the position, the shape, the size, the height and the like of an obstacle. The image processor 3 can generate a headlamp control command according to the image information, and the first controller can adjust the starting number and the brightness change of the LED light sources according to the headlamp control command so as to project different light types, so that the purpose of adaptive illumination of the headlamp is achieved, and the intelligence of the headlamp is realized. Different light types are that the matrix headlight 4 lights, darkens or closes some LED light sources according to the road surface condition of difference, can realize functions such as anti-dazzling, pedestrian remind, bend illumination from this.
Further, in the embodiment of the present invention, the infrared stripe is formed by a horizontal stripe with a light and shade interval. Or the infrared stripes are formed by light and shade spaced vertical stripe-shaped stripes. Or the infrared stripes are formed by horizontal stripe stripes and vertical stripe stripes which are arranged in a light and shade interval; the horizontal stripe and the vertical stripe are arranged in a staggered mode.
Therefore, the light and dark spaced stripe projected by the spotlight assembly 1 can be a single horizontal stripe or a single vertical stripe, and of course, a pattern of light and dark spaced infrared stripes with a superimposed effect can be emitted by combining two or more spotlight assemblies 1. Preferably, the two spotlight assemblies 1 are combined to emit a pattern of superimposed alternating bright and dark horizontal stripes and vertical stripes. The pattern formed by the horizontal stripes is advantageous for calculating the front and rear conditions of the road surface, and the pattern formed by the vertical stripes is advantageous for calculating the left and right conditions of the road surface. The coexistence of horizontal stripes and vertical stripes can improve the resolution of road surface monitoring.

Therefore, when the matrix headlamp 4 is switched on to the high beam mode, the camera 2 monitors the variation of the infrared stripes on the driving road surface, and when the infrared stripes become distorted stripes, the image processor 3 feeds back the calculated road surface condition to the matrix headlamp 4. For example, when the image information includes vehicle image information, the image processor 3 may generate a headlamp control command according to the image information, and the first controller may adjust the turn-on number and the brightness change of the LED light sources according to the headlamp control command, so that the matrix headlamp 4 turns off a part of the LED light sources, and a small number of LED light sources operate to prevent a high beam from dazzling other vehicles, thereby achieving an automatic anti-dazzling effect of the headlamp.
Further, in an embodiment of the present invention, the image information includes pedestrian image information, and the headlight control command includes a flicker adjustment command corresponding to the pedestrian image information;
the first controller is in data connection with the matrix headlamp 4 and the image processor 3 and is further used for obtaining and controlling the LED light source to be turned on to flicker according to the flicker adjusting command.
Therefore, when the matrix headlamp 4 is switched on to the high beam mode, the camera 2 monitors the variation of the infrared stripes on the driving road surface, and when the infrared stripes become distorted stripes, the image processor 3 feeds back the calculated road surface condition to the matrix headlamp 4. For example, when the image information includes pedestrian image information, the image processor 3 may generate a headlight control command according to the image information, and the first controller may control the LED light sources to be turned on or to blink a part of the LED light sources at a certain frequency according to the headlight control command, so as to prompt pedestrians to pay attention to the vehicle, thereby implementing a headlight and pedestrian protection function.
