■智能偏心检测
▪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0.5~l.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比捡测理念
▪ 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偏心理念
▪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%
▪上/下/左/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)
