立体印刷用柱镜光栅线数检测方法研究
|
摘要
目的研究一种快速准确检测立体印刷用柱镜光栅线数的方法。方法柱镜光栅固定在测试平台上,测头基座沿水平方向移动,同时保证测头上的触头在垂直方向始终保持与光栅表面接触;然后由计算机实时采集测头水平方向和垂直方向的位移,把数据保存到数据库,并在计算机屏幕上显示柱镜光栅表面曲线;最后把测头水平方向和垂直方向的位移数据代入数据处理算法,计算出被测光栅线数。结果以100线的柱镜光栅作为被测光栅进行测试,测试结果与传统方法检测的线数非常接近,并且能在60 s内完成测试。结论该方法避免了传统人工观测带来的误差,并把测试时间由300 s降至60 s,具有高效率、高稳定性和高可靠性的优点。
Objective To study a detection method of grating scalar lines in stereoscopic printing. Methods First, a lenticular grating was fixed on the test platform. The base of a probe moved along the horizontal direction, and at the same time the terminals of the probe always kept contacting with the surface of the lenticular grating in the vertical direction. Then the horizontal and vertical displacements of the probe were acquired by a computer in real time and the displacements data were saved to the database. The measured curve of the lenticular grating surface was displayed on a computer screen. Finally the horizontal and vertical displacements of the probe were substituted into the data processing algorithm and the line number of the tested grating was calculated. Results A lenticular grating with 100 lines was measured by this method as a test grating. The experimental results showed that the number of lines tested by this new method was very close to the number of lines tested by the traditional method and the test could be finished within 60 seconds. Conclusion The error of the traditional artificial measurement was avoided in the new method and the test time was reduced to 60 seconds from 300 seconds. The method showed the advantages of high efficiency, high stability and high reliability.
