A method and device for determining an illumination angle

Abstract

The invention relates to a method and device for determining an illumination angle. The method includes the following steps that: illumination intensities measured by each photoelectric sensor in a sensor array are acquired; an illumination intensity matrix is determined according to the positions of the photoelectric sensors in the sensor array and the illumination intensities measured by the photoelectric sensors; the direction of a light source is determined in a plane where the sensor array is located according to the illumination intensity matrix; an included angle between illumination and the normal of the plane is determined according to the illumination intensities, a pre-stored corresponding illumination intensity of the light source and a pre-measured distance from the light source to the sensor array; and the illumination angle is determined according to the direction of the light source and the included angle. According to the method and device for determining the illumination angle, complicated and expensive devices are not required, and the illumination angle can be measured through devices such as the sensor array, and therefore, the illumination measurement method is simpler and more convenient compared with an illumination angle measurement method in the prior art.

Description

technical field [0001] The present application relates to the field of information technology, in particular to a method and device for determining an illumination angle. Background technique [0002] At present, optoelectronic informatics has become an important symbol of the development of science and technology in the information society. In many practical applications, people hope to be able to measure the angle of illumination, and even hope to be able to locate the position of the light source. [0003] However, in the prior art, the method for measuring the illumination angle generally needs to be implemented based on complex and expensive equipment, which makes it difficult to popularize the illumination angle measurement method in the prior art, and cannot be applied on a large scale in people's daily life . [0004] Therefore, how to measure the illumination angle simply and conveniently has become an urgent problem to be solved. Contents of the invention [0...
