Description
Technical field
The present invention relates to bore hole 3D technology field, in particular to for debugging controlling for bore hole 3D display device parameter
Tool and system.
Background technology
As 3D shows constantly developing for industry, the requirement more and more higher that people are shown to 3D.When traditional 3D shows
When being difficult to the constraint for breaking away from wearable device, bore hole 3D shows, receives more and more attention.The mode that bore hole 3D shows has many
Kind, but at present, either large-size screen monitors commercialization bore hole 3D shows, or smaller screen personal consumption class bore hole 3D shows, post mirror bore hole 3D
Display Technique all has larger advantage.And show that smaller screen personal consumption class bore hole 3D shows relative to large-size screen monitors commercialization bore hole 3D
(such as bore hole 3D panel computer, bore hole 3D notebook computer etc.) possesses more vast audient group, with bigger commercial value.Post
Mirror bore hole 3D panel computer will obtain good 3D display effects, it is desirable to have accurate 3D parameters.And receive to produce work at this stage
The restriction of skill, is inconsistent with the 3D parameters of a batch of post mirror bore hole 3D panel computer, and this is required in production most
Afterwards the stage 3D parameters of post mirror bore hole 3D panel computer to be debugged.At present to post mirror bore hole 3D panel computer
When 3D parameters are debugged, manual debugging is used.Test picture is shown under the 3D states of post mirror bore hole 3D panel computer
Test pictures are watched in face, tester's eyes at the viewing ratio, when tester's right and left eyes are respectively seen difference and correct
Test pictures (as left eye sees complete red picture, right eye sees complete green picture) when, write down 3D parameters, complete debugging.It is such
There are some shortcomings in debud mode：1. human eye viewing, randomness are big.Interpupillary distance (i.e. binocular interval) phase not to the utmost of different testers
Together, interpupillary distance difference causes to debug the 3D parameters for obtaining variant.Other tester eyes and tested panel computer in debugging
Luffing angle is difficult to hold, it is equally possible to cause the difference of 3D parameters.2. tester's right and left eyes watch different test charts for a long time
Picture, it is easy to fatigue, or even eyes are damaged.3. pure artificial operation, work efficiency are lower, are unfavorable for product volume
Produce.
