Abstract

The invention discloses a billet counting device based on a machine vision technology. The billet counting device comprises a laser marker, a laser transceiver, a camera and a laser reflector, the laser marker and the laser transceiver are installed on one side of the conveying roller way, the camera is installed on the other side of the conveying roller way and opposite to the laser marker, and the laser reflector is installed on the other side of the conveying roller way and opposite to the laser transceiver. The laser marker obliquely irradiates the conveying roller way downwards, and the irradiation direction is perpendicular to the moving direction of the conveying roller way. The camera is additionally provided with an optical filter, and the optical filter is matched with the wavelength of the laser marker. The invention further discloses a steel billet counting method based on the machine vision technology, the width value of the steel billet is obtained based on the machine vision technology, the number of the steel billets is accurately counted, and the requirements for accurately metering the number of the steel billets and accounting the steelmaking cost of a steelmaking plant can be met.
