Abstract

The invention relates to the field of image processing techniques and provides an illuminant surface luminescence uniformity detection apparatus, method and system. The illuminant surface luminescence uniformity detection apparatus comprises an illuminant fixing support, an image acquisition device and an image processing device. The illuminant fixing support is used for fixing an illuminant. The illuminant fixing support is provided with several reflective prisms arranged around the illuminant. The image acquisition device is used for carrying out image acquisition on light emitted by the illuminant fixed on the illuminant fixing support. The acquired images include a front image and several side images. The image processing device is used for carrying out processing on the front image and the several side images to obtain the uniformity parameter values of the illuminant so as to realize detection of illuminants in various intensity scopes. The detection speed is fast and the cost is relatively low.

Description

technical field [0001] The invention belongs to the technical field of image processing, and in particular relates to a device, method and system for detecting uniformity of light emission on the surface of a luminous body. Background technique [0002] Luminous bodies include spheres, cubes, cones, polygons, and arc-shaped luminous surfaces, which are widely used in electronic products such as toys, business office supplies, and electronic games. Since the luminous body has certain requirements and standards for the uniformity of the luminous body, a corresponding detection device for the uniformity of the luminous body has emerged as the times require. [0003] At present, for the detection of the uniformity of luminescence on the surface of luminous bodies, integrating spheres and other equipment are mainly used for detection. This detection method has low detection efficiency and is only suitable for the measurement of small batches of samples such as laboratories, and i...
