Abstract
In this study, we develop the work auxiliary carriage for the transport of crops after pick up in the greenhouse. In order to develop an carriage can introduce easily, We develop a system for steering analyzes the images from camera mounted on the carriage without any special construction and equipment in greenhouse. We intended for strawberry hydroponics greenhouse especially. In this paper, we describe in detail a method of image processing for determining the steering direction of the carriage especially. To demonstrate the effectiveness of the proposed method, we confirmed straightness using carriage for test by running test.
