Description
Technical field
The present invention relates to 3D display technical field more particularly to a kind of 3D display calibrating installations and calibration method.
Background technique
Recently as the continuous maturation of 3D technology, 3D display industry development is swift and violent, and all kinds of 3D display products are pushed to one after another
Market, naked eye 3D display technology are come into being.Naked eye 3D display technology is to control two eyes not that can not allow by any tool
See that two width have parallax, different from picture from display screen, they is reflected into brain, people will generate solid
Sense, it also utilizes the principle of parallax of human eye, by sending to different pictures respectively to viewer or so two, to reach vertical
The visual effect of body, due to naked eye 3D display observer can not wearing spectacles carry out 3D display experience, more meet the mankind
Nature experience, meet the market demand of 3D display, have biggish market and business opportunity.
However, pervious 3D display product carries out that face angle is needed to watch when 3D display, the mistake of viewing location can band
Carry out greatly dizzy sense, user experience effect is poor.At this moment the naked eye 3D display system with human eye tracking shows greatly to compete
Advantage, using the front camera and 3D display screen of high refresh rate, can real-time capture viewer's eye position, and adjust 3D in real time
It has been shown that, so that watching range with wide 3D.Specific product, the 3D mobile phone including a variety of brands, 3D plate, 3D computer,
Have using tracing type naked eye 3D display technology.
But with the elongated of time, structure aging is used, camera is shifted, display screen displacement etc. factor will lead to
The 3D display parameter and human eye trace parameters and equipment calibrated when factory mismatch, and 3D viewing effect is caused to be deteriorated.Especially,
External 3D display equipment, such as 3D pad pasting, 3D display set, if final matched equipment differs greatly, necessarily user from
Row calibration.
Meanwhile 3D cell phone manufacturer faces the obstructions such as brand recognition is low, and it is difficult that Sales Channel is promoted, and user's trial and error is at high cost,
Naked eye 3D is caused to promote slow.Apple is used in some users, and the reputable brands mobile phone such as Huawei allows him to abandon existing mobile phone,
A unknown brand 3D mobile phone is replaced, it is relatively difficult.
