According　to　convenience　and　accuracy　problem　of　clinical　wound　area　measurement　method,　the　wound　area　measurement　software　is　designed　based　on　the　Android.　The　wound　image　is　photographed　by　the　Android　device　and　is　cut　out　and　converted　to　the　grayscale　image　and　the　binary　image.　The　invalid　area　is　eliminated　and　the　valid　area　is　extracted.　The　pixels　of　wound　area　are　counted.　According　to　the　pixel　ratio,　the　wound　area　is　calculated　and　displayed　on　the　Android　device.　Results:　The　wound　area　can　be　marked　automatically　by　wound　area　measurement　software.　According　to　the　proportion　of　wound　area　and　1cm2　reference　object　on　the　same　distance,　the　wound　area　data　are　calculated　and　displayed.　The　error　of　the　software　measurement　is　within　±1.112%.　The　software　can　complete　the　measurement　of　irregular　wounds　accurately.　The　wound　area　is　measured　by　the　wound　area　measurement　software　based　on　Android　using　Non-contact　method　such　as　taking　picture,　calculating　and　processing.　It　avoids　the　problem　of　wound　infection　and　substitutes　for　direct　measurement　method　widely　used　on　clinic.　©　2014　IEEE.
