■智能偏芯检测

投影在扩散板的影像Pseudo Color转换后取得发光体中心方向的Profile测算双峰值

为了获得最大指点Scan变曲点方式来扫描360度全部范围

每一个角度对比(双峰比)当中的最小值作为偏心比率来判定良不良

▪ LED供电流及影像条件是影像的中心部位不在于爆火状态条件之下调试

▪ Lens 中心部位的影像用曲线识别看出结果会明显的减少明暗

English

▪Profile measurement double peak value obtained by projecting the Pseudo Color image of the diffuser after obtaining the center of the illuminator

▪In order to obtain the maximum pointing Scan change point method to scan the full range of 360 degrees

▪The minimum of each angle comparison (bimodal ratio) is used as the eccentricity ratio to determine the good defect.

▪LED current supply and image conditions are the central part of the image is not debugged under the fire condition

▪The image of the center of the Lens is identified by the curve to see that the result will significantly reduce the brightness and darkness.

■歪角不良检查功能

设置位置坐标要对标准试的产品中心点调试到画面的中心

▪ Lens和扩散板之间的距离0.5l.5mm Setting

在画面最亮的范围内找出中心点

▪ Center Error Offset来检查歪角不良

English

▪Set the position coordinates to be aligned with the product center point of the test and debug to the center of the screen.

▪Lens corners will form a light image beyond the central position

▪Distance between Lens and diffuser plate 0.5 ~ 1.5 mm Setting

▪Find the center point in the brightest range of the picture

▪Center Error Offset to check for bad corners

■Pola3.0双峰Al比检测理念

▪ Box 范围内A,B <= Peak Point确认检查有效性判断

▪ A,B > Peak Point的情况下双峰比来形成判定Peak不良

English

▪A, B <= Peak Point confirmation check validity judgment in Box range

▪A, B > Peak Point case, the peak-to-peak ratio is not formed, and the result is poor.

■Cross-Alens Shift偏芯理念

找出中心点(影像整体对比0.3%的大小)

从中心点有影响到偏心的外角找出Edge(影像整体对30%的区域)

画像整体大小圆设定·Max50%

///右偏心的情况下Edge部分倾向于偏移部分

这个部分是Step影像理任何大小(光亮分散)的原型检查

▪ Center&Edge30%区域距离为0.1单位算出(3600个)

长形和短形比率来算出=Sum小(1800个)/Sum大(1800个)

English

▪Find the center point (the overall size of the image is 0.3%)

▪Find the Edge from the outer corner of the center point that affects the eccentricity (the area where the overall image contrast is 30%)

▪The overall size of the screen is set to: Max 50%

▪Edge part tends to shift part when up/down/left/right eccentricity

▪This part is a prototype inspection of any size (light dispersion) of the Step image.

▪Center Edge 30% area distance is calculated as 0.1 unit (3,600)

▪Long and short ratios are calculated = Sum is small (1,800) / Sum is large (1,800
