Proportion- and perspective-based shape corrector for framing for art painting

Abstract

The invention provides a proportion- and perspective-based shape corrector for framing for art painting. The shape corrector comprises a framing board, of which a surface is a transparent glass, wherein a proportion- and perspective-based shape correcting device I and a proportion- and perspective-based shape correcting device II are arranged respectively at the upper end and the lower end of theframing board. When proportional adjusting is performed on a piece of drawing paper on the framing board, an upper gear is rotated; and when a first upper proportional adjusting board retracts, a second upper proportional adjusting board can extend out due to a transmission direction difference between the second upper proportional adjusting board and the first upper proportional adjusting board,set in the movement process. Thus, the opposite movements of the first upper proportional adjusting board and the second upper proportional adjusting board as well as the opposite movements of a firstlower proportional adjusting board and a second lower proportional adjusting board can be represented as proportional retraction or extension by any point on the drawing paper; and thus the first upper proportional adjusting board and the first lower proportional adjusting board simultaneously retract along a diagonal line, and a part for which correction is formed is calibrated by proportional scales of the second upper proportional adjusting board and the second lower proportional adjusting board, so that proportional calibration and correction can be achieved.

Description

technical field [0001] The invention relates to a device for framing an art painting, in particular to a proportional perspective correction device for framing an art sketch. Background technique [0002] Sketches and color sketches have been introduced to China from abroad for more than a hundred years. However, problems such as framing composition, proportional relationship, perspective changes, and structural shapes in sketching have always been difficult problems, which plague many artists, especially beginners. Due to the difference in angle, distance and height between the position of the painter and the painting object, there will be different or even subtle changes in proportion and perspective, which makes it difficult for many art workers to accurately grasp it, identify it, and draw it in the drawing. Colonel checked and corrected it. Correct observation, proper composition, exact outline, and correct physical structure are the beginning of painting. If this step...

[0005] Among the above, it has obvious defects. For beginners, the above adjustment ruler cannot be adjusted in equal proportions at any position, so it can only play a role of correction and assistance.
