机器视觉布料色差检测设备原理
Principle of machine visual cloth chromatic detection equipment

布料由变频器控制传送系统传送,在布料上方沿幅宽方向平行放置一个高强度线性光源,照亮布料表面,线阵CCD视觉检测设备横向置于布料上方,采用工业镜头完成布料的二维扫描。布料连续传送,线阵CCD视觉检测设备的相机将连续采集到的布料表面图像数据传输至计算机,在计算机中应用色差公式完成色差的计算与评分。

The cloth is transmitted by the transmission system controlled by the frequency converter. A high intensity linear light source is placed parallel in the width direction above the cloth and illuminates the surface of the cloth. The line array CCD visual inspection equipment is placed above the cloth horizontally, and the two dimensional scanning of the cloth is completed by industrial lens. The material is transmitted continuously. The camera of the linear CCD visual inspection device transfers the data of the surface of the material to the computer. In the computer, the color difference formula is used to calculate and score the color difference.

器视觉布料色差检测设备由光源模块、线阵CCD视觉检测成像模块及计算机色差计算模块组成,所以,要求光源光强可调。这样子才能满足颜色测量的光谱分布的LED线性白色光源,配备控制器,可调节亮度。
The color difference detection equipment of the visual fabric is composed of the light source module, the linear CCD visual inspection imaging module and the computer color difference calculation module, so the light intensity of the light source is adjustable. Only in this way can the LED linear white light source of the spectral distribution of color measurement be satisfied, equipped with a controller and adjustable brightness.

线阵CCD视觉检测成像模块,一般布料的幅宽都在1m以上,采用单一面阵CCD视觉检测成像受视场限制,采用基于线阵CCD视觉检测扫描成像,不受线阵帧转移频率的限制,布料副宽方向和布料运行速度方向都能够获得很高的检测分辨率。
Linear array CCD vision detection and imaging module, the width of the general fabric is more than 1m, and the single array CCD vision detection imaging is restricted by the field of view. The scan imaging based on the linear array CCD vision is used to detect the scan imaging, which is not limited by the frequency of the line array frame transfer. The wide direction of the cloth pair and the direction of the speed of the cloth can be detected to be very high detection resolution. The rate of.

计算机色差评分模块,色差检测是纺织品质量控制的一项重要内容,但是传统人眼检测效率低下,有时候还容易漏检,而使用计算机色差评分,不仅提高了生产效率,降低了工人劳动强度,还帮助企业在产品质量控制的问题上发挥着巨大的作用。
Computer color difference scoring module, color difference detection is an important content of quality control of textiles, but the traditional human eye detection efficiency is low, and sometimes it is easy to leak, and the use of computer color difference score, not only improves the production efficiency, reduces the labor intensity of the workers, but also helps the enterprise to control the quality of the product. It plays a great role.
