Measurement device and method of visible equipment imaging brightness

Abstract

The embodiment of the invention relates to the technical field of the electronics, and discloses a measurement device and method of visible equipment imaging brightness. The measurement device of thevisible equipment imaging brightness comprises camera equipment co-line with a principle optic axis of the visible equipment, and a processor; the processor is in communication connection with the camera equipment; the processor is used for the camera equipment to capture a testing image displayed by the visible equipment and taking the captured image as a reference image, wherein the testing image is a pure white image; the processor is further used for acquiring color brightness of each pixel point of the reference image, and acquiring the real imaging brightness information of the visible equipment according to the color brightness of each pixel point and the brightness function of the real brightness, wherein the brightness function is a mapping relation of the color brightness and theactual brightness. The embodiment of the invention further provides a measurement method of visible equipment imaging brightness. By adopting the measurement device disclosed by the embodiment of theinvention, the imaging brightness of the visible equipment can be objectively measured, and the device is low in cost, fast and efficient and high in accuracy.

Description

technical field [0001] The embodiments of the present invention relate to the field of electronic technology, and in particular to a measuring device and method for imaging brightness of a visual device. Background technique [0002] Virtual reality VR (Virtual Reality, referred to as "VR") and augmented reality AR (Augmented Reality, referred to as "AR") are visual devices. The basic principle of imaging is to project two virtual images on the corresponding parts of the left and right eyes of the user through the camera. , and divide the field of vision into three dimensions: far and near, deep and shallow, and front and back, and form a 3D visual virtual effect through the integration of multi-source information. VR devices and AR devices are emerging products that rely on optical imaging. The brightness of their imaging will directly affect the user experience: if the imaging brightness of VR and AR devices is too low, the picture will feel dim, which will make it difficu...

Problems solved by technology

[0003] The inventors have found that there are at least the following problems in the prior art: the luminance measuring instrument in the prior art can only be used for point measurement, and cannot measure the luminance of a surface. Therefore, the luminance measurement of visual devices in the prior art mainly remains In the subjective test link, that is to judge the brightness and darkness of the image subjectively through human observation, the cost is high, that is, it is not objective and efficient
