    四、白板检测方案

    img

    1.坏点检测

    基于模板图片亮度重建进行坏点检测,梯度检测。

    具体:重建理想成像时的白板图像,进而与原图进行对比,通过一定手段筛选坏点候选点,最终输出坏点区域

    2.坏团检测

    A.基于梯度角度重建的坏团检测。

    可以管控明显程度

    B.基于识别局部特征的微弱坏团检测

    具体:根据坏团区域亮度分布,变化趋势进行识别

    C.微弱曲线检测

    具体:通过多特征分析等手段来识别曲线类局部变化比较复杂的不良区域。

     

    3.色温,色彩,亮度均匀性检测

     

    五、光轴检测方案

     

    imgimg

    通过拍摄照片,检测图片的中心和Mark蓝色方块的中心的距离来检测光轴垂直度,距离越短光轴垂直度越高

     

    六、视场角检测方案

    img

    计算测试卡每个中方块边长是多少个像素,同时计算实际的色卡每个方块的长度,得出每个像素对应现实的长度,然后计算对角线长度,从而得出视场角覆盖范围

    按键检测,电机旋转检测,音频是否有声检测等功能检测,根据客户实际需求定制
