Abstract

Exposure time is one of the important reasons that affect the accuracy of 3D vision measurement. Different exposure times need to be set to ensure the measurement accuracy for parcel volume measurement in different lighting environments. The existing exposure time setting is mainly based on manual experience and lacks scientific basis. For this reason, this paper proposes an algorithm for automatic camera exposure adjustment based on fuzzy rules. The exposure time is coarsely adjusted first and then finely adjusted to obtain a more accurate exposure time. Experiments show that the proposed camera automatic exposure algorithm using fuzzy rules is fast and reliable.

基于模糊逻辑的线结构光传感器自动曝光控制
曝光时间是影响三维视觉测量精度的重要因素之一。在不同的光照环境下,包裹体积测量需要设置不同的曝光时间,以保证测量精度。现有的曝光时间设定主要基于人工经验,缺乏科学依据。为此,本文提出了一种基于模糊规则的相机曝光自动调节算法。先粗调曝光时间,再细调曝光时间,以获得更精确的曝光时间。实验表明,基于模糊规则的相机自动曝光算法快速可靠。
