识别圆形铝条上的红色标记 应检测圆形铝条上的红色标记。此处的红色是在先前的工序中涂上的,表示铝条的冶金缺陷部位。此时应注意,这里的红色因涂法不同 (手工或自动) 可能有明显的差异,且可能在运输过程中局部受到磨损。此外,还应考虑到铝条可能受到污染,因为它部分被存放在露天,且捆绑用的钢条可能会在铝表面产生锈迹。
Detection of a red color mark on an aluminum rod
The task is to detect a red color mark on an aluminum rod (the red color mark informs about defect metallurgic domains in the aluminum rod). At this, the red paint which is used for color marking can differ and furthermore it can happen that the color mark is partly scraped. In addition an aluminum surface can be contaminated with rust (comes from a steel band, which is used for fixing the rods in a former process), which drifts also into the red color.
