Automatic Exposure Control of Line Structured Light Sensor Based on Fuzzy Logic

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.
