Abstract

The invention discloses a machine vision technology based leather detection device. The device includes a support, an industrial camera, an LED lamp and a control device; the industrial camera can take pictures of leather on a conveyor belt; the LED lamp can illuminate the leather on the conveyor belt; and the control device can obtain the area and position information of the leather by taking pictures of the leather on the conveyor belt through the industrial camera, and control a nozzle to perform spraying on the leather on a corresponding position or with a corresponding area on the conveyor belt when the leather is conveyed to a spraying chamber by the conveyor belt. A leather detection method is also disclosed. The method includes the following steps: 1, performing camera calibrationon the industrial camera, and determining the position of a spray gun and the speed of the conveyor belt being V; 2, obtaining the area of the leather or the position information of the leather on theconveyor belt; and 3, controlling, by the control device, the spray gun to perform spraying on the leather on the corresponding position or with the corresponding area. Thus, the positions of the leather can be accurately detected and measured; the scope of detecting and measuring the positions of the leather is large; and the device and method are stable and reliable in operation.
