Abstract:
Data input about geometrical parameters of a processed detail is an important stage in CAD galvanic processes. The work objective is the reception of spatial coordinates of surface points of a detail from their two-dimensional image on the drawing. To solve the given task, the algorithm including the following stages: transformation of a set of coordinates of tops in the list of pieces, tracing connectivity of pieces among themselves; definition of projections; construction of rectangles describing each of three objects; finding the beginning of coordinates of three projections for the use of this point further pasting this three-dimensional model; construction of a three-dimensional model on the basis of the received two-dimensional one, is offered in the paper. It is offered to use the paralleling of calculations in order to speed up these calculations.
Keywords:
three-dimensional (3D) geometrical model; analysis of spatial scenes.
