有色物体视觉检测如何选择光源?

How to select light source for visual inspection of colored objects?

机器视觉检测中,经常有碰到产品有多种颜色的。如果是做颜色检测,通常选用白光;在不做颜色检测的情况下,如果用白光照射,取得照片在黑白情景下可能几个颜色的灰度值都很接近,那么会影响到结果的判断错误。这种情况下,就要采取有色光源来打光,消除这种干扰。

In visual inspection there are often a variety of colors encountered in the product. If you are doing color detection usually white in color; do not detect cases if the white light made several pictures may gray color values are very close in the black and white scenario it will affect the error of judgment. In this case take the color light to light eliminating the interference.

不透明物体的颜色是由它反射的色光决定的,使用互补色(互补色就是色环中正好相对的颜色)光源进行照明待测物体,则物体呈现深黑色,方便后期对图像进行运算判断。若照射到物体的色光的颜色不同,它反射的色光也不同,也就是说我们见到的物体颜色也不同。

Opaque object color is determined by its light reflection the use of complementary colors (complementary color is the color ring in opposite color) lighting object the object appears dark the image of convenient operation and judgment. If the color of the object light is different it reflects the color of light is different that is to say we see the object color is also different.
