Abstract: A light source module 100 for use with a multi-camera array 130 in a video surface inspection system includes a first light emitter 104 which extends lengthwise across the entire width of a sheet 106 to be inspected. Light from the first light emitter 104, which preferably comprises one or more fluorescent lamps, is received by a light guide 110 and carried by the guide to uniformly illuminate a band extending entirely across the width of the moving sheet. The light guide comprises a transparent thermoplastic such that the light receiving end 118 of the guide can be bent to define a plurality of sections which can be axially aligned with a corresponding plurality of fluorescent lamps. The light source module can also assist the inspection system in overcoming redundant data processing problems by providing second light emitters 134 which illuminate the sheet in overlapping portions 132 of the fields of view of adjacent cameras of the multi-camera array 130 to define data dividing points. Accordingly, duplicated data generated by the video cameras can be divided among the cameras at the defined data dividing points such that duplicated data is only processed once by the video surface inspection system.

Abstract translation: 与视频表面检查系统中的多摄像机阵列130一起使用的光源模块100包括：第一光发射器104，其沿着待检查的片材106的整个宽度方向延伸。 来自第一光发射器104的光，其优选地包括一个或多个荧光灯，被光导110接收并由引导件携带，以均匀地照射整个穿过移动片的宽度延伸的带。 导光体包括透明的热塑性塑料，使得引导件的光接收端118可被弯曲以限定可以与相应的多个荧光灯轴向对准的多个部分。 光源模块还可以通过提供在多摄像机阵列130的相邻摄像机的视场的重叠部分132中照亮片材的第二发光器134来辅助检查系统克服冗余数据处理问题，以定义数据分割点 。 因此，由摄像机生成的复制数据可以在定义的数据分割点处的摄像机之间进行划分，使得仅由视频表面检查系统处理一次复制的数据。
