Zusammenfassung: | To provide a new surface inspection system that is inexpensive.SOLUTION: Provided is a surface inspection system comprising: an image sensor and an image processing device 3. The image sensor images the surface of an inspection object and includes a transmission unit for transmitting a pixel value 2111 to the image processing device 3. The image processing device 3 includes an integrated pixel generation unit 4 for integrating a plurality of adjacent pixels 211 to generate one integrated pixel 41 in accordance with the size and shape of an assumed defect 95 having been assumed in advance, an allocation unit 5 for calculating one representative value 511 from the pixel values 2111 of a plurality of pixels included in the integrated pixel 41 on the basis of the pixel value 2111 sent from the image sensor and allocating as an integrated pixel value 52, an integrated image reconstruction unit 6 for reconstructing an integrated secondary image 61 from the integrated pixel value 52, and an assessment unit 7 for assessing the size and shape of the defect on the basis of the integrated secondary image 61 and the integrated pixel value 52.SELECTED DRAWING: Figure 2
【課題】コストのかからない新たな表面検査システムを提供する。【解決手段】イメージセンサと画像処理装置3を備え、イメージセンサは、被検査物の表面を撮像し、画素値2111を画像処理装置3に送る送信部を有し、画像処理装置3は、あらかじめ想定した想定欠陥95の大きさおよび形状に合わせて、隣接する複数の画素211を統合して1つの統合画素41を生成する統合画素生成部4と、イメージセンサから送られた画素値2111に基づき、統合画素41に含まれる複数の画素の画素値2111から1つの代表値511を算出し、統合画素値52として割り当てる割当部5と、統合画素値52から統合2次元画像61を再構成する統合画像再構成部6、統合2次元画像61および統合画素値52に基づき、欠陥の大きさおよび形状を判別する判別部7を有することを特徴とする表面検査システム。【選択図】図2 |
