Abstract:
Room is the un it o f quan tity survey fo r adorn ing ma teria ls. Automa ted partition fo r room s, a fter struc ture and layout inform ation of all com ponents ( co lumn, w al,l beam, slab) and e leva tion have been recognized, is very important to achieve the targ et o f automa tion in calcu lation. M eanw hile, the effic iency and accuracy o f quantity survey w ill be greatly im proved. Accord ing to the cha racte ristics o f room, a h ie rarch icalm e thod for room pa rtition based on closure- borders is presented in th is paper and rea lized in system o f autom ated recogn ition and quantity survey. The proposed m e thod recogn izes room contours on the sam e floor using an outline- tracing procedure, and figures out room bo rders crossing seve ra l floo rs by po lygon operations. Th ism e thod so lves we ll the problem s o f autom ated recogn ition o f room s, greatly reduces the w ork load o f quan tity survey for ado rn ing m a terials, and builds the foundation o f establishing the 3D m ode l o f dig ital bu ild ing and h igh level applica tions such as arch itecture m anag em ent in fo rm ation system.
