The　digital　image　correlation　method　is　a　high　precision　and　non-contact　ground　deformation　monitoring　method,　which　is　widely　used　in　surface　deformation　monitoring.　However,　according　to　its　principle,　different　surface　characteristics　have　great　influence　on　the　monitoring　results.　In　this　paper,　a　regional　digital　image　slope　monitoring　method　is　established　to　meet　the　monitoring　requirements　of　different　areas　of　the　same　slope.　Firstly,　the　features　of　different　regions　in　the　image　are　identified　according　to　the　optical　region　detection,　and　then　the　deformation　calculation　method　is　matched　according　to　the　features　of　different　regions.　Finally,　according　to　the　binocular　vision　principle,　the　three-dimensional　displacement　of　the　slope　is　obtained.　Taking　a　highway　slope　in　Qinhuangdao　as　an　example,　we　realised　all-weather　and　full-field　deformation　monitoring　of　slope,　and　verified　the　applicability　and　feasibility　of　regional　digital　image　slope　monitoring　method.　The　applicability　of　digital　image　correlation　method　in　slope　monitoring　is　improved.
