【摘要】：图案几何形态决定了产品的视觉效果,形态变换是图案创新设计的重要途径之一.本文从图像视觉变换技术出发,利用图像控制点的坐标位置信息,实现服饰图案的快速变形.首先确定图案的中心点,根据角度和距离确定像素点相对于图案中心点的位置;然后依据该像素点、对应相同角度的原图像边缘点和新图像边缘点分别到中心点的距离,计算出像素点坐标变换的比例系数;再据此系数和极坐标与直角坐标的转换关系以确定该像素点新坐标的位置;遍历原图中每一个像素点,最终实现图案的几何形态变换.结果表明:该方法的实现有利于提升传统图案设计、加工效率和视觉效果,满足快速时尚的行业设计需求.
[Abstract]:Pattern geometry determines the visual effect of the product, and shape transformation is one of the important ways of pattern innovation design. In this paper, based on the image vision transformation technology, the coordinate position information of the image control point is used to realize the rapid deformation of the dress pattern. Firstly, the center point of the pattern is determined, and the position of the pixel point relative to the center point of the pattern is determined according to the angle and distance; then, according to the pixel point, the distance from the edge point of the original image and the edge point of the new image to the center point respectively, the proportional coefficient of the coordinate transformation of the pixel point is calculated, and then the position of the new coordinate of the pixel point is determined by the transformation relationship between the coefficient and the polar coordinate and the rectangular coordinate. Traversing each pixel in the original image, and finally realizing the geometric transformation of the pattern. The results show that the realization of this method is beneficial to improve the traditional pattern design, machining efficiency and visual effect, and meet the needs of fast and fashionable industry design.
