Abstract

The invention provides a linear scanning camera device which integrates bar code recognition and volume detection as a whole. The device comprises a gantry frame. The gantry frame is fixed above a conveyor belt of a conveyor. The top of the portal frame is provided with a linear camera, a light supplementing lamp and a reflector unit. The camera collects pixel rows perpendicular to the plane of the conveyor and forms a right angle with the advancing direction of the conveyor. A sensor is arranged at the inlet of the conveyor. The conveyor is provided with an incremental encoder. The sensor, the incremental encoder and the camera are connected with an image processing industrial computer. The pulse of the encoder directly controls the triggering of the image shooting of the camera, whereinthe triggering interval is determined in such a manner that the imaging of a square is not deformed during the object height calibrating process. The industrial computer carries out bar code recognition on collected images, and calculates the length, the width, the height and the volume of a regular object.

Description
