摘要
为了研究投影机光学性能测量方法,建立一个精度高、操作方便且成本低的投影机光学性能自动测量系统。利用该系统的逐像素扫描的特点,在全面扫描、9点和13点方法下对多种投影机进行了数据测量并得到投影机的性能指标。经过对9点和13点测量方法得到的性能指标与全面扫描得到的数据的比较分析,提出了更为合理的5点测试方法。
For researching the measure method of the characterization of protector, a high precision, cheap and convenient measure system was set up, which can automatically measure data. The system can scan the test image of projector. By analyzing the measured data, 9 positions method and 13 positions method were compared. By discussing the advantages and disadvantages of the traditional measure method, the better 5 positions method was advanced.
