Abstract

For a multiview autostereoscopic three-dimensional display based on the lenticular lens, the manufacturing errors and inhomogeneities of the lenticular sheet can deteriorate the view image quality. A calibration method is proposed by filtering the pixel mapping of all view images. Each view is first sequentially turned on to show a white test image, and the intensity distribution of every view will be analyzed. Then individual filter functions are derived and applied to the corresponding view images to correct the subpixel value. Experimental results show that the proposed method can solve view image loss and significantly improve the quality of stereoscopic images.

Data Availability

The images of the eight views were analyzed in the optimization to calculate the filter functions. The camera images were captured with the LMK Camera and have been included in Fig. 5. The raw LMK data may be obtained from the authors upon reasonable request.
