Embodiment three
In order to bore hole 3D module corrects efficiency, present embodiments provide the bearing calibration of a kind of bore hole 3D module, as shown in Figure 4, main processing steps comprises:
Step S41: the red green light splitting composite diagram play in bore hole 3D module to be corrected is projeced on projection screen;
Step S42: capture the image that projection screen shows;
Step S43: the image of crawl and the red green spectroscopy scheme preset are contrasted.
In step S42, capture the image that projection screen shows, comprising: capture the image that projection screen shows according to set frequency.
In step S43, the image of crawl and the red green spectroscopy scheme preset are contrasted, comprising: the mode that the image of crawl grows from weak to strong according to sharpness according to sort algorithm is sorted; According to the result of sequence, image the strongest for sharpness and the red green spectroscopy scheme preset are contrasted; Result according to contrast determines that whether bore hole 3D module to be corrected is qualified.
Below in conjunction with Fig. 2, Fig. 3 and Fig. 5, the process that the utility model bore hole 3D module means for correcting carries out bore hole 3D correction is discussed in detail.
Bore hole 3D module means for correcting of the present utility model is utilized to carry out bore hole 3D timing, a projection screen 4 is placed at the fixed range place, dead ahead of bore hole 3D module 3 to be corrected, the row of utilization figure software (or 3D player) plays red green light splitting composite diagram on bore hole 3D module 3 to be corrected, be positioned at the projection screen 4 forward anchoring position place camera 5 be connected in work computer and capture red green image that curtain maps (for strengthening the quality of image of capturing and arriving, shading curtain can be added in curtain surrounding and enclose the environment building darkroom), the image grabbed is stored in the specified folder of work computer, capture quantity and can be set to the number of image frames that in the unit interval, camera 5 is captured, as frame p.s. 30.Sort algorithm (as bitmap ordering algorithm) is utilized the mode that the figure film size figure of storage is grown from weak to strong according to sharpness to be arranged, because of the red green image that image is row figure software process quality, therefore every width image all can show the parameter value of this image when showing, as Cot value, Pitch value etc., during candid photograph, these data synchronously can be extracted by special image data processing software (as OpenCV software) and store with image one_to_one corresponding that (3D module to be corrected is connected in work computer, in arranging, 3D module to be corrected is set to basic display unit, therefore data be can synchronous transmission and store), OpenCV software is utilized to be carried out by the parameter value of the image extracted after process and design load carries out exhaustive comparison, it is more clear that comparison result is more then judged to close to design parameter value, finally contrast with the strongest parameter value of a width figure of sharpness and the parameter value of design, it is qualified to be then defaulted as in rational fluctuation area, underproof product is then rolled off the production line etc. in time pending, it is made not flow into next production station, whole correction work flow process is as Fig. 3.
In Fig. 3, a, b, c, d are four connecting rods that can slide, the area size of groove 7 can be adjusted in actual applications according to the size of produced module, middle groove 7 part is the backlight 1 of Chang Liang, 3 is bore hole 3D modules to be corrected, 4 is projection screens that map image needs, and 5 is the cameras capturing image, and 6 is that image received device is specifically as follows computer.First get by operating personnel the bore hole 3D module 3 to be corrected that upper station flows down in production, put into the groove 7 in correction station after taking-up and connect wire rod, the shading curtain of projection screen 4 surrounding that hangs down encloses starts working, after personnel to be operated detect that correction completes on the monitor of work computer, raise shading curtain to enclose, disconnect the connection wire on bore hole 3D module and bore hole 3D module put into the lower station of production line inflow.
Can further Optimizing Flow when the automated production of small size 3D module, because the inclination angle designing grating is constant, it is constant for can being defaulted as its Cot value, therefore can judge separately the quality of 3D module according to the value condition of Pitch value or the sharpness situation of image.
This kind of bearing calibration that the utility model proposes can be dissolved in the whole production procedure of bore hole 3D module, and can complete the correction of 3D panel fast.The method can judge the quality (used time is in 10S clock) of a 3D panel fast, can also reject defective products timely makes it not flow into down in one production process, greatly improve production efficiency, reduce material loss and cost of labor, particularly to the making of undersized 3D panel advantageously.
The above; be only embodiment of the present utility model; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; change can be expected easily or replace, all should be encompassed within protection domain of the present utility model.Therefore, protection domain of the present utility model should described be as the criterion with the protection domain of claim.
