Abstract

A transport system includes: an image capturer included in a transport vehicle; a positional deviation detector that detects a positional deviation between a pre-correction position at a time when the article is placed on a reference transfer destination and a reference placement position; a corresponding relationship calculator that finds a pixel deviation between a pre-correction image and a post-correction image and calculates an actual deviation amount per unit pixel, the pre-correction image being captured at an initial position of the transport vehicle by the image capturer, and the post-correction image being captured by the image capturer at a position of the transport vehicle deviated by the positional deviation; and the correction amount calculator that finds a pixel deviation between the post-correction image and a transfer destination image captured of another transfer destination and calculates a correction amount from the pixel deviation and the actual deviation amount per unit pixel.
