Aiming　at　the　problems　of　large　work　intensity,　low　intelligence　level　and　low　efficiency,　the　production　date　intelligent　recognition　algorithm　was　designed.　The　algorithm　optimizes　the　image　preprocessing　algorithm,　combines　the　grid　statistical　method　and　the　projection　density　method　to　extract　the　feature　vector,　and　uses　the　support　vector　machine　algorithm　to　identify　the　production　date.　The　experimental　results　show　that　the　algorithm　can　accurately　identify　the　production　date　and　achieve　the　expected　recognition　effect.　Has　practical　significance.
