Comprehensive stereoscopic display detection.The standardization test and appraisal research of bore hole stereoscopic display key parameter relatively lags behind.Cause naked at this stage
Eye stereo product quality and visual effect are very different.
For example bore hole stereoscopic display shows right and left eyes image separation over the display, then spectators couple are sent in matching respectively
Eye.The mistake of right and left eyes image can be caused to send when matching is destroyed, produce crosstalk.Crosstalk ratio as stereo display technique most
Important evaluation index, reach 5% just makes the spectators' generation vision of more than half uncomfortable enough；If crosstalk ratio exceedes
10%, it will appear from the situation that stereo-picture is difficult to merge in spectators' brain.

It is right.In addition, control cabinet 2028 is also communicated to connect with test and appraisal terminal 300, the control signal that test and appraisal terminal 300 is sent can be received.
Control cabinet 2028 is also communicated to connect with first axis motor 71, the second axial direction electric machine 61, the 3rd axial direction electric machine 43, can be according to connecing
Received control signal drives the first axis motor 71, the second axial direction electric machine 61, the 3rd axial direction electric machine 43 to rotate.
Wherein, in the present embodiment, control of the test and appraisal terminal 300 to spatial movement device 202 is realized by control cabinet 2028
System, so that adjusting image collecting device 100 moves to default locus, improves the automation of the assessment device 200.
In some other embodiments, the control cabinet 2028 can also be omitted.
In addition, 3 d display device display effect test and appraisal equipment can also include remote controler, the control cabinet 2028, treat
Survey 3 d display device 10 and test and appraisal terminal 300 is correspondingly arranged on infrared receiving module, to realize by a manner of infrared remote control
Start image collecting device 100, mechanical assessment device 200 and the test and appraisal terminal 300.Meanwhile the test and appraisal terminal 300 is according to survey
Examination needs to adjust the test and appraisal view shown by the 3 d display device to be measured 10 by control cabinet 2028.
In practical applications, can be first when needing to carry out display effect test and appraisal to a certain 3 d display device 10 to be measured
First the 3 d display device 10 to be measured is installed on control cabinet 2028, and connects control cabinet 2028 and test and appraisal terminal 300.So
Afterwards by appropriate opening ways, such as, infrared remote control, starts 3 d display device 10 to be measured, image collecting device 100, control
Case 2028 processed and test and appraisal terminal 300.Then, user inputs three axis (first axles of the spatial movement device in test and appraisal terminal 300
To second is axial, and the 3rd is axial) coordinate.According to three axis parameter input by user, test and appraisal terminal 300 is sent to control cabinet 2028
Some control instructions, including position command and idsplay order.Control cabinet 2028 will display after receiving some control instructions
Instruction is sent to 3 d display device 10 to be measured, and/or, each axial direction electric machine (first axis motor 71,61 and of the second axial direction electric machine
3rd axial direction electric machine 43) so that the display test and appraisal view of 3 d display device to be measured 10, spatial movement device 200 are adopted with motion video
Acquisition means 100 move to three-dimensional position input by user；Meanwhile terminal 300 of testing and assessing also receives image collecting device 100 and collects
Test and appraisal view, and adopt the test and appraisal rank that the 3 d display device 10 is determined according to the test and appraisal view that collects.
Through the above way as it can be seen that being different from the situation of the prior art, the 3 d display device provided in this present embodiment
Display effect test and appraisal equipment can make the image being fixedly mounted on the mechanical assessment device by control machinery assessment device
Harvester realize relative to the position of 3 d display device to be measured and the adjustment of posture so that, described image harvester can
With at diverse location with the test and appraisal view of the different Posture acquisition 3 d display devices, and by the test and appraisal view collected send
To test and appraisal terminal, so that the test and appraisal view that test and appraisal terminal is collected according to described image harvester determines the solid to be measured
The test and appraisal rank of display device, can accurately measure the stereo display effect of large-sized 3 d display device, and
The 3 d display device that can accurately test and assess corresponds to different observation postures and what different observation space position was presented includes crosstalk
The bore hole stereoscopic display overall effect of the key indexes such as rate, colour purity, evaluating result are more accurate and comprehensive.
Finally it should be noted that：Above example is only to illustrate the technical solution of the application, rather than its limitations；At this
Under the thinking of application, it can also be combined between the technical characteristic in above example or different embodiment, step can be with
Realized with random order, and many other changes of the different aspect there are the application as described above, for simplicity, they do not have
