FIELD: TV methods of measurement of surface in system with computer. SUBSTANCE: examined surface is illuminated by family of light beams, one of two extreme beams in family is selected in advance for setting of start of analysis of image of beams. While analyzing position of image illuminance in columns of image is measured. Selected beam is made to correspond to one of light spots nearest to parallel planes of beams of boundaries of image. Its image is determined as sequence of light spots coupled to selected spot arranged on both sides of selected spot. Any column with maximum number of light spots is chosen from columns crossing image of selected beam. Spatial form of surface of object is determined by image of beams to both sides from chosen column as assemblage of light spots coupled to spots of this column. EFFECT: increased accuracy and authenticity of measurements of volumetric bodies with simultaneous expansion of technical capabilities. 3 dwg
