线束顺序检测

通过电缆颜色检查多线电缆的正确管脚分配。位置和颜色由每根导线决定。每根电缆的目标颜色都是通过鼠标点击图像中的每根线缆单独设定的。无需指定RAL表格中的颜色值。

CIE LAB颜色空间描述了三维颜色空间中所有可感知的颜色,其中亮度值L垂直于颜色平面(a,b)(参见https://en.wikipedia.org/wiki/CIELAB_颜色空间).

彩色图像可以在我们的图像分析软件中使用CIE-LAB对象进行分析。每个对象确定任意可参数化区域的LAB值。LAB值是三维色彩空间中的一个点。每种颜色都有一个独特的坐标。为了便于说明,该坐标也可以显示为三维坐标。

在图中,7种有线颜色(红色、蓝色、紫色、棕色、绿色、粉色、黄色)在颜色空间中显示为直线。由于电缆绝缘或光学影响的颜色变化,LAB值存在偏差。因此,所确定的颜色值通常略偏离于示教的颜色值。如果计算了一个LAB值到所有示教的颜色线的距离,则可以将LAB值指定给距离最短的颜色线。

相机系统可以管理任意数量的产品型号变体。通过型号和相应的示教入系统的颜色顺序可以检查出正确的颜色顺序。

The correct pin assignment of multi-wire cables is checked by means of the cable colour. The position and colour are determined for each individual wire. The target colours of each cable are taught-in individually, using a type of construction and clicking on each individual cable in the camera image with the mouse. It is not necessary to specify colour values from RAL tables.

Functionality

The CIE LAB colour space describes all perceivable colours in a three-dimensional colour space in which the brightness value L is perpendicular to the colour plane (a, b) (see https://en.wikipedia.org/wiki/CIELAB_color_space).

Colour images can be analysed in the V60 image analysis software using the CIE-LAB object. The object determines the LAB values of an arbitrarily parameterisable area. The LAB result value is a point in the three-dimensional colour space. Each colour has a unique coordinate. For illustration purposes this coordinate can also be displayed as a 3D coordinate.

In the figure, 7 taught-in cable colours (red, blue, violet, brown, green, pink, yellow) are shown as straight lines in the colour space. There are deviations in the LAB values due to production-dependent colour variations in the cable insulation or optical influences. The determined colour value is therefore usually slightly off the taught-in colour. If the distance of a LAB value to all taught-in color lines is calculated, the LAB value can be assigned to the colour line with the shortest distance.

The camera system manages any number of variants. The correct sequence is checked by means of a type specification and the corresponding taught sequence.
