Fruit.
General principle
The present invention exists with the proportional principle Design enlargement chi of similar triangles corresponding sides as measuring tool, the person of drawing a picture
(viewpoint refers to that the person's of drawing a picture eyes are relative for sighting distance (distance of the person's of drawing a picture eyes to border face) distance determined by bar and viewpoint position
In the locus residing for minute surface), by seeing depending on being connected to the structure image reflected in mirror reflection mirror border face before drawing board simultaneously
By the isosceles triangle pantograph for being connected to vertical small end (can left and right, move up and down and 360 degree rotate) smooth border face, with
The shorter base of two similar triangle amplification chis is measurement (chi), to the length of the body profile of building, width, height in mirror image
Degree and angle of inclination are measured respectively, and the result measured is fixed by fixing screws and auxiliary fix bar, then its is right
The long base (chi) that should amplify, along the horizontal slide rod movement set by drawing board forward position after rotating vertical straight connecting rod 180 degree, and will
It turns to drawing board drawing paper patterning positions (also can be in conjunction with auxiliary ruler), will measure profile line segment along chi side with pencil and draw
Go out, by that analogy.Due to the back side setting-out of the chi after steering, thus drawn building reduces the normal visual effect (mirror of people
As " the anti-figure " for normal vision image).
Why mirror reflection mirror mirror-reflection building is used, then measured by the smooth minute surface of similar triangles pantograph
Amplification is without allowing it directly to measure and amplify again against building outdoor scene, because by isosceles triangle pantograph against the straight of building
When line profile measures, it is unstable that the own activities of the automatic swing in gauger head and eyes easily causes sight, double
Eye depending on thing has dual, fuzzy image phenomenon, in addition, see the actual distance sense for regarding outdoor scene, make the chi straight line of pantograph with
The outline of straight line of building is difficult to determine to overlap, scene outline especially farther out, and mirror reflection effect is then different, and it will
Building outdoor scene is reflexed in mirror, can determine the plane relation of building and speculum, it is determined that viewpoint, sighting distance is with similar
The smooth minute surface in chi face of triangle amplification chi measures contour of building in mirror, thus its chi side and contour of building can be clear, steady
Fixed, accurately coincidence.
Application method
<1>When generally painting from life, easel, the person of drawing a picture all are buildings drawn by " towards ".And built using drawn by present invention selection
After building thing, building drawn by the person of drawing a picture and easel " backwards ", and according to practical adjustments easel height, minute surface in the position of drawing board and
The positioning mark of minute surface, the angle of inclination (mirror tilt angle degree) of drawing board, allow structure image to reflex in mirror and tighten fixed anti-
Penetrate the fixing screws of cell mount.
<2>Need to regulate isosceles triangle pantograph exaggerated (short chi) according to composition and amplify (long chi) two chi side
The proportionate relationship of relation, while according to the angle of inclination of minute surface, (track, short handle) mobile regulation before and after making to horizontal slide rod,
Make the smooth minute surface of isosceles triangle amplification related scale and tighten its fixing screws.
<3>Sighting distance bar upper end T-bar (left side or the right) is against the forehead for the person of drawing a picture, to represent viewpoint and sighting distance position
Put, should keep viewpoint and sighting distance relatively stable during amplification and fixed, and with screening rose plate block another eye (left eye or
Right eye eyeball), the person of drawing a picture is with building mirror image in simple eye eyeball viewing-mirror, to reach more preferable effect.
<4>It is determined that viewpoint sighting distance position, with the short chi side of isosceles triangle pantograph (angle ∠ eaf are supportted big or reduced)
Measure the profile (big height, width, length) of building in mirror, after measurement to keep measurements by triangle amplification chi and
Fixing screws, eccentric fixing card in auxiliary fix bar are tightened, then by isosceles triangle pantograph together with vertical link rotatable 180
Degree (allowed during rotation vertical connecting rod (person of drawing a picture) inclines backward, allow isosceles triangle pantograph to avoid drawing board) is simultaneously sliding along level by it
Lever slides (its position is just opposite with mirror position), while unscrews eccentric fixing card, pantograph is made up or down movement
To drawing board drawing paper patterning positions (such as by triangle amplification chi place drawing board drawing paper on when, its chi face can not smooth drawing board, can lead to again
Cross unscrew short handle fixing screws in slotting square tube, allow short handle to make elastic regulation in square tube so as to reach triangle amplification
The smooth drawing board of chi --- triangle amplification related scale is parallel with drawing board, then tightens fixing screws) determine position after tighten bias again
Fixing card, then along chi side draw determined by measure line segment, by that analogy.The friendship between line segment is found during outline line as far as possible
Point, intersection point can represent the start position of drawn another line segment, thus another line segment of picture since intersection point, as can not find line segment
Intersection point, except directly measuring can also find the start position of drawn line segment by increasing boost line；Such as draw same height on building
Spend the several windows of size identical, after having drawn one and representing that these windows are in the lines of same straight line height, from this
Building certain point is determined under bar straight line, measures inclining from this point to the starting point of each window breadth line segment from this point
Rake angle, the start position of the line segment of window breadth is found by angle of bank measurement, so as to draw the position of each window.And
(circular arc line two-end-point and highest can be determined by the track put on short straight line or arc for circular, circle circular arc line
Point), then connected by hand-drawing line.
<5>In viewing-mirror picture in position determined by sighting distance bar, the scenery Chang Chao showed due to the limitation needs of minute surface size
, can be by changing viewpoint position for beyond minute surface but needing the scenery part that shows outside appearance --- sight is raised or dropped
It is low so as to seeing the scenery part outside super mirror and then measure；Also eyes (viewpoint) can such as be allowed closer to minute surface by changing sighting distance,
So as to allow eyes to see bigger field of view, then adjust the short chi of pantograph and the proportionate relationship of long chi and then measure amplification.
Drawn scenery can remove mirror at speculum behind position, be resetted again according to positioning mark after finishing.
<6>After drawn building contour line paints, amplifier is turned to, the person of drawing a picture is facing generally towards building by becoming " backwards "
Thing simultaneously makees necessary adjustment to institute's outline, applies light and shade, completes paintings.
In addition, present invention design can be rotated by 360 ° isosceles triangle pantograph, in order to measure the inclination angle of building
Degree.Placed when triangle amplification chi rotates 180 degree after smooth minute surface is measured by cylinder one on drawing board, former positive chi
Face turns to drawing board (drawing paper), now towards the fixation spiral shell connected by triangle amplification chi and vertical connecting rod of drawing board (drawing paper)
Nail, pantograph now have a distance with drawing board.To enable chi face after triangle amplification rotates 180 degree to keep flat with drawing board
OK, the rear end (right dead slot one end) at similar isosceles triangle pantograph base bar bc both ends and auxiliary foot bar ag can be increased
One height, make 3 points of height for peak and highly roughly the same；Or add the auxiliary scale of a smooth drawing board again, by auxiliary scale
Chi side be close to the hold-doun nut for connecting pantograph bc and two waists, then along the setting-out of auxiliary scale side, width=(amplification of auxiliary scale
Chi bc width ﹣ head diameters) ÷ 2).In addition, similar triangles pantograph can design it is multiple, such as large, medium and small specification, big chi can
For drawing big contour of building lines, and medium and small chi can be used for the medium and small profile of picture, so using more convenient.
