Embodiment Construction
[0019] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.
[0020] Such as figure 1 As shown, a method for automatic adjustment of display brightness and color temperature of AR glasses according to the present invention comprises the following steps:
[0021] Step 1: Preset the corresponding relationship between the pupil diameter range and the brightness value displayed by the AR glasses;
[0022] Using the scheme of preset scenes, different preset scenes represent different ambient brightness, turn on the infrared camera 1 on the AR glasses, respectively measure the range of pupil diameter in different preset scenes, and user preset AR glasses in different preset scenes The display brightness value of the pupil diameter range forms a corresponding relationship with the display brightness value of the AR ...

The invention discloses a method for automatically adjusting the brightness and color temperature of AR glasses. The method comprises the following steps of presetting a corresponding relation between a pupil diameter range and a display brightness value of the AR glasses, after the pupil diameter is obtained each time, adjusting the AR glasses to the corresponding brightness value, calculating a theoretical pupil diameter Dseq of the human eyes according to a pupil diameter calculation model, acquiring the difference between the reference pupil diameter Dseq obtained through the brightness information in the view field range and the pupil diameter obtained through the infrared image at the same moment, and adjusting the color temperature of the AR glasses according to the difference value. The brightness of the AR display device can be adjusted more accurately based on the diameter of the pupil of the human eye, and the display color temperature is adjusted according to the total color temperature of the ambient light, so that a better display effect is achieved.
Description
technical field [0001] The invention relates to the field of AR glasses, in particular to a method for automatically adjusting brightness and color temperature based on pupil diameter and light environment. Background technique [0002] The usage scenarios of AR glasses usually need to see the displayed content and the external environment clearly at the same time, so there is a high requirement for the ability to automatically adjust the display brightness. The automatic brightness adjustment of AR glasses is mostly realized by sensing the ambient light brightness. However, the brightness of ambient light sometimes cannot correctly reflect people's perception of brightness. On the one hand, the position of the human eye and the position of the light sensor are generally different, which will lead to differences in the light environment in which the two are located; on the other hand The reason is that the two have different perceptions of brightness. The principle of the l...
