Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Example (b):

referring to fig. 1-2, in a sub-pixel arrangement of intelligent lighting, An image recognition device recognizes An illuminated scene and stores a normal state picture of a normal still object, if a vehicle and a pedestrian pass through, the image recognition device finds An object similar to a human shape, the image recognition device processes a changed pixel point in An image and controls the brightness of An illumination area inside An illumination lamp, the illumination area is divided into a plurality of areas, which are respectively marked as a1 to An, and n takes a value of 2500; the area is divided into a plurality of areas, so that the areas can be conveniently distinguished, the analysis of people at a far position is facilitated, the brightness of the image in the independent area is reduced, the image in the area is compressed, the brightness similar to the face shape in the area is reduced, the illumination is carried out in a mode of combining a plurality of small bulbs, and the brightness of part of the bulbs in the area is firstly reduced; the small bulbs are used for illuminating the area, so that the brightness of the bulbs in the illuminating area can be controlled conveniently, and the illumination brightness in a certain area can be adjusted conveniently and independently.

Further, the image recognition device recognizes the color of the skin, and the upper part of the skin has hair in a capillary manner, similar to the shape of a face; the human face and other things are distinguished through the color of the skin of the pedestrian and the similar hair, so that the area around the person can be conveniently identified, and the image compression mode is that the color of the edge of the image is mixed and then the color of the image in the area is changed into the color; the size of the image is effectively reduced by changing the color, the retrieval of real objects in the image is facilitated, the color mixing mode adopts multicolor matching and is divided into five colors of red, yellow, blue, white and black, and then the real objects with similar colors are distinguished; different similar colors are classified in a multi-color matching mode, so that pure colors are filled in the image, the edges of the divided areas are convenient to distinguish, the image is compressed and then is subjected to data storage, various images are classified and recognized, and the common face shapes of the areas are distinguished; after the data are stored, the people frequently appearing in the area are identified by identifying a plurality of pieces of data, so that the accuracy of identifying the face of the people frequently appearing in the area is improved, the image is faded into black and white, is distinguished through the brightness of the image, and then is subjected to face identification; through a black-white two-color display mode, the human face in the edge area inside the image can be more favorably identified through the difference of the reflection intensity of human skin compared with that of different real objects; after the image is identified, the image is compared with objects in a normal state, and then passing pedestrians and vehicles are distinguished, and through controlling the brightness of different areas of the illuminating lamp, the illumination brightness of the face is reduced, the image data is compressed, the processed data is reduced through compression, the data space of storage and processing is reduced, the area is divided, the number of the illumination units controlled in the area is changed, the object is convenient to judge and illuminate, and the effect of the illumination intensity of the adjustment part in the sub-area is convenient to adjust.

In summary, the working principle and working process of the sub-pixel arrangement mode of the intelligent lighting are that when the intelligent lighting device is used, firstly, after an image is recognized, the image is compared with things under normal conditions, then, passing pedestrians and vehicles are distinguished, the image is divided into a number A1-A2500, image data is compressed, processed data is reduced through compression, then, the data space for storage and processing is reduced, the area is divided, then, the number of lighting units controlled in the area is changed, then, the brightness of different areas of the lighting lamp is controlled, and further, the illumination brightness of the human face is reduced.
