Abstract

An array light projection device with adjustable images comprises an infrared camera (1), a microprocessor (2), an array lamp (3) and an infrared light source (4). The array lamp (3) comprises a lamp control system (5) and array type distributed lamps (6). The infrared light source (4) lights a moving target object. The infrared camera (1) records the image of the target object. The microprocessor (2) is used for analyzing images so as to obtain the outline of the target object. The luminance value of each lamp (6) is calculated according to the mapping relationship of the recorded position of the outline of the target object and the light spot position corresponding to the array lamp (3). The luminance of each lamp (6) is controlled through the lamp control system (5). The image of the target object is finally projected on a wall.

Description

【Technical field】 [0001] The invention relates to a light projection device, in particular to an image-adjustable array light projection device. 【Background technique】 [0002] There are currently two techniques used to achieve interactive light and shadow effects on walls. The first technology uses a projector to project images onto the wall to achieve interactive light and shadow effects. This technology can project precise and delicate images, but it is generally not used in outdoor systems due to the limitations of the brightness, projection distance and price of the projector. The second technology is to use LED display screens to achieve interactive light and shadow effects. The brightness of each LED on the LED display screen can be controlled, and one LED corresponds to one display pixel. This technology can be used for outdoor advertising with image display. CN201110451227.4 announces a LED lighting interactive system, including an LED display screen composed of a ...
