The　license　plate　location　is　the　basis　of　the　license　plate　occlusion　detection.　On　the　basis　of　the　positioning,　the　key　is　to　accurately　determine　the　license　plate　occlusion.　This　paper　proposes　a　license　plate　occlusion　detection　algorithm　based　on　character　jumping.　For　the　positioned　occluded　license　plate　area,　it　is　determined　whether　the　license　plate　is　occluded　according　to　the　number　of　license　plate　character　jumps.　The　number　of　jumps　of　a　normal　license　plate　is　greater　than　or　equal　to　14　times.　If　the　license　plate　is　blocked,　the　number　of　jumps　is　less　than　14　times.　The　experimental　results　show　that　the　detection　effect　of　the　license　plate　occlusion　based　on　this　algorithm　has　a　good　judgment　result.　©　2019,　Springer　Nature　Singapore　Pte　Ltd.
