detection: pcb board cable color.
2, testing requirements: judgment cable color
3, the detection process: on-line "trigger" camera detection output
visual detection system consists of a ccd camera, lens and light source.
1, the light source
the ring led lighting
the high resolution ccd sensor. model: 110s
total pixels: 9,000,000 pixels
effective pixels: 900 million pixels
optical zoom: 10x optical zoom
sensor type: ccd sensor
sensor size: 1/2.3-inch
maximum resolution: 3456 × 2592
3, the computer system
acquisition of signal and image processing.
learning template for grayscale or geometric images and image positioning.
learn and locate objects and patterns in your images.
2, color detection
color recognition of: detecting an image area inside the color type and the quantity of each color, it is judged whether or not the set value.
color matching quantifies which colors and how much of each color exist in a region of an image and uses this information to check if another image contains the same colors in the same ratio.
3, the output
output test results: pass or ng, and location of the error.
control the industrial digital i / o lines on the device to communicate inspection results to other industrial devices such as plcs or pcs.
