随着LED灯的出现和灯本身的附加功能，正在制造的汽车前照灯的数量正在增加。需要测量制造的前照灯的光分布特性，以确保其质量。然而，传统方法需要大量的测量时间和较大的空间。因此，出现了无法及时完成前照灯生产的光分布测量的问题。为了解决这个问题，我们提出了一种基于光场的复杂光分布特性测量方法。我们的方法是在距离光源一定距离处测量平面的光强，然后估计光源的光分布特性。 与传统方法相比，该方法能够在较窄的范围内和较短的时间内测量光分布特性。

With the advent of LED lights and the added functionality of the lights themselves, the number of automobile headlights being manufactured is rising.  Manufactured headlights need to be measured for light distribution characteristic to assure their quality. However, the conventional method requires a lot of measurement time and a large space. As a result, problems arise where light distribution measurement cannot be completed in time for headlight production. We propose a measurement method for complex light distribution characteristic based on light fields to solve this problem. Our method is to measure the light intensity of planes at a certain range distance from the light source and then estimate the light distribution characteristic of a light source. This method would enable the measurement of the light distribution characteristic in a narrower range and in a shorter time than the conventional method.
