摘　　要：柱透镜光栅的平整性对立体图像的显示效果有很大影响,而单纯通过肉眼观察很难对平整性给出准确判定。针对这个问题提出了一种柱透镜光栅平整度的检测方法。在对最佳区域拍摄的测试图像进行分析的基础上,模拟出透镜曲面三维模型,并通过计算串扰区域面积得出透镜平整度计算公式。最后若平整度超过合理范围就对其进行平整处理。实验证明此测试方法可以较准确地检测出柱透镜的表面平整性,也对后期校正处理提供有效的判断依据。The evenness of the Lenticular Lens exerts significant influence on the image display. Whereas, it is difficuh to make an accurate judgment of the evenness simply through eye-observation. To solve the problem a kind of Lenticular Lens evenness detection method is put forward in this paper. In the best view location shooting test based on the analysis of the image, the lens surface 3D model is simulated. By calculating the crosstalk area, the formula of Lenticular Lens evenness is got. The test results as whether to provide a reference for physical correction. The experiment proves that this tes- ting method can accurately detect the Lenticular Lens surface evenness, but also provide an effective judgement basis for later correct process.
