Embodiment Construction
[0025] Such as figure 1 As shown, the automatic detection method of copper particles in nickel foam of the present invention is: a plurality of color image acquisition devices for collecting the surface images of nickel foam are configured on the upper and lower sides of the detection workbench of nickel foam, and these color image acquisition devices are compatible with The industrial computer is connected, and the nickel foam surface image data collected by the color image acquisition device is input into the industrial computer, and the white balance filter is first performed to eliminate the color cast effect in the image acquisition of the color image acquisition device; then the RGB (Red, Green, Blue) color The space is converted to the HSV (Hue, Saturation, Value) color space, and after the conversion, median filtering is performed based on the H channel to eliminate noise; then the detected H channel is set to distinguish the value of 80<H<180. The nickel foam surface a...
