Projection driving platform and method based on wide-angle photography

Abstract

The invention relates to a projection driving platform and method based on wide-angle photography, and the platform comprises: an on-site projection mechanism which is used for executing a corresponding projection action to an automobile entity corresponding to a target region based on the relative position of each target region in a directional blurred image; a wide-angle capturing mechanism which is arranged on a cross rod above the urban road and is used for performing real-time capturing operation on the environment where the urban road is located so as to obtain a corresponding road environment image; and a pixel analysis mechanism which is used for acquiring centers of respective geometrical shapes of the two target areas, and sending out a vehicle distance over-close signal when the number of pixels occupied by the shortest path between the two centers is less than or equal to a preset number threshold. The projection driving platform and method based on wide-angle photography are easy to operate and wide in application. Due to the fact that the warning operation of on-site projection can be executed on the two automobile objects which are too close to each other on the urban road, a driver is helped to relieve emotion, and normal driving operation is recovered.

Description

technical field [0001] The invention relates to the field of projection driving, in particular to a projection driving platform and method based on wide-angle photography. Background technique [0002] The light sources used in projection equipment include traditional high-intensity gas discharge light sources (such as ultra-high pressure mercury lamps, short-arc xenon lamps, and metal halide lamps) and new light sources represented by LED light sources and laser light sources. Traditional light source projectors usually darken and turn yellow with the attenuation of light emitted by the light source after being used for a period of time (such as brightness attenuation, color saturation and contrast reduction, etc.). , even if the bulb is still glowing, the bulb has to be replaced because of it. Therefore, light decay has become a major obstacle that cannot be overcome by projectors using traditional light sources. With the development of semiconductor lighting technology ...

Traditional light source projectors usually darken and turn yellow with the attenuation of light emitted by the light source after being used for a period of time (such as brightness attenuation, color saturation and contrast reduction, etc.). , even though the bulb is still glowing, the bulb has to be replaced because of it

Therefore, light decay has become a major obstacle that cannot be overcome by projectors using traditional light sources.
