Embodiment 1
[0020] Embodiment 1: a kind of method of sorting timber according to color and grain, it comprises the following steps:
[0021] a) Create category data: According to the factors of wood color, wood grain inclination angle and color spot ratio, create a category data of wood images to be classified. The color factor distinguishes three levels of color difference, and selects three representative wood samples and calibrates them with a video imaging device. The calibration colors are: FF9900 (R=255, G=153, B=0), F8CC34 (R=248, G = 204, B = 52), E3CF63 (R = 227, G = 207, B = 99); the inclination angle of wood grain is divided into two levels, the inclination angle is less than or equal to 5° for straight grain, and the angle is greater than 5° for twill grain; The factor of spot ratio is divided into three levels, the proportion of stain (wood grain color) is less than or equal to 1% of the board surface, the proportion of stain is 1-10% of the board surface, and the proportion ...
Embodiment 2
[0032] Embodiment 2: as figure 1 As shown, a device for sorting wood according to color and wood grain, it includes a wood conveyor belt 1, a wood video imaging device 2, several wood sorting devices 3 and a program control system, and the video imaging device 2 is installed at the beginning of the wood conveyor belt 1 At the end, a number of wood sorting devices 3 are equidistantly installed on the side of the wood conveyor belt 1 downstream of the video imaging device 2, and the video imaging device 2 and a number of wood sorting devices 3 are respectively connected to the program control system circuit. Such as figure 2 Shown, described video imaging device 2, it comprises a base 21, and a door font frame 22 is installed on one side of base 21, slideway 24 is arranged on the two columns of frame 22, and a shading cover 29 is slidably installed on the slideway 24 Lighting lamp 28 is installed on the inside of hood 29, a support 27 is fixed above the hood 29, a camera 26 is...
