近年来，多种自由立体显示技术的实现手段如视差壁障、柱状透镜、多层投影技术等被提出。虽然其市场产品众多，然而，对于自由立体显示的效果测试方法和评价指标方面的研究现仍处于起步阶段，如何有效地判断自由立体显示技术的效果优劣，评价显示设备的质量，是自由立体显示技术发展的关键问题之一。本文首先论述了自由立体显示的常规测试方法，包括主观测试、客观测试、统计测试3类，进而对几种最新的基于亮度分析的典型自由立体显示效果测法和指标进行了技术分析;最后总结了自由立体显示测试的发展方向，指出其会向主观与客观测试结合，仿生人类视觉的信息采集、信息处理方向发展，以使对其显示效果的测试更全面，结果更接近人的真实感受。

In recent years, many techniques have been proposed to achieve stereoscopic display, such as parallax barrier, lenticular lens and multiprojector technology. There are many products of AS3D, but the method of testing and evaluating the AS3D equipments is still in initial stage. How to effectively determine the effect of AS3D equipments becomes one of the important issues of AS3D development. This paper firstly elaborated the conventional testing methods, including the subjective testing, objective testing and the statistical testing. Secondly, several latest measuring methods and index of AS3D based on brightness information have been analyzed. Finally, we discussed the development trendency of the AS3D measuring system and noted that the methods of the subjective and objective testing might be combined, while bionic information collection and processing will replace conventional tests. So the test results will be much closer to the people's true feelings.
