Example Sentences:

	1.	Introduction of the current status and development of key technologies of the three - dimensional contour measurement . creation of the measuring means of free curved surfaces of objects , based on the passive stereo visual technology and the active liquid crystal grating encoding technology 综合结构光法和立体视觉法，在对传统视觉传感器结构统一的基础上，提出了基于被动式双目立体视差技术和主动式液晶光栅编码技术传感器，实现物体的三维形貌数字化测量。
	2.	Paper [ 76 ] provides a integer algorithm for rasterizing free curves , we need change the curve form to implicit function form , then use curve ' s positive - negative property to draw , but we ca n ' t use this algorithm when curve ' s degree is higher than 3 and this algorithm ca n ' t avoid using multiplication ; paper [ 77 ] provides a new generating algorithm , this algorithm can draw bezier very well , but for b - spline curve , we need use convert them into bernstein base form . because this process spends a lot of time , this algorithm has not a good speed and effect for rendering rational b - spline curve 现在经常采用的算法也是基于几何的算法(即线式生成算法)和基于像素的算法(点式生成算法) ;文献78 ]提供了一种有理参数曲线的快速逐点生成算法，该算法对有理b吮ier曲线的绘制，能起到很好的作用，但是对于有理b样条曲线，必须先通过多项式的代数基与bemstein基间的变换矩阵，把原式用bemstein基表示，这一过程由于计算量大，降低了曲线生成的速度和效率
