outline drawing
2.In the process of the image projection, match and splicing, the current image splicing technology is studied, the shortcoming and excellences of each kind of image splicing algorithm are analyzed. The paper adopts the color image becoming directly the gradation outline drawing, filtering the chromatic aberration disturbance and after sampling the sketchy match and precise matches to complete joining two images.
3.first calculation method : doing horizontal projection drawing on drawing piece, K value is introduced by area equation of projection drawing, K value is obtained by area equation , along outline of projection drawing to add K value, that is , outline shape of blank drawing, principle area-equal and shape similar are used .
9.In addition, the painter uses sketch ably on canvas neatly, the idea that passes through combinative west sketch and Chinese traditional line drawing in traditional ink and brush style, outline way waiting for ability, development goes the artistic trait of confluence of a kind of Chinese and Western.
10.In order to speed up the design of plough bottom surface, we have established the computing and drawing FORTRAN program. On the computer DJS-8 we have computed for the outline, the horizontal trace, the performance templet curves of plough surface. On the drafting machine DC300 we have drawn the graphs.
