摘要：

In　this　paper,　a　test　system　of　book　quality　is　designed　for　book　binding　machines,　folder　machines　and　book　leaf-gathering　machines.　And　this　system　with　an　external　camera　of　NTSC　or　PAL　standard　uses　digital　signal　microcomputer　processor　of　high　speed　to　gather　and　process　images.　Synchronous　dynamic　random　access　memory　circuits,　Flash　memory,　RS232　serial　communication　circuits,　video　decoding　and　external　signal　serving　circuits　are　developed　for　this　test　system　of　book　quality,　and　CPLD　chip　is　a　controlling　unit　of　this　system.　Algorithms　of　gray　correlation　and　gray　average　are　also　derived　to　obtaining　image　information　for　this　test　system　of　book　quality,　and　these　methods　make　the　system　running　fast　and　recognizing　more　categories　of　books.　Experiments　show　that　precision　of　this　test　system　of　book　quality　is　about　99%.
