Research and Simulation of an Efficient Circular Interpolation Algorithm

Abstract

During the process of conventional DDA circular interpolation, the synthesis feed rate fluctuations often, the machining errors are large also. A new efficient arc interpolation method is proposed in this paper, which uses the principle of DDA circular interpolation, it’s function is optimized and improved, Radius is used as the basis of interpolation feed, the left normalized data and pre-loaded are used also. The simulation result of VB program show that efficient circular interpolation method not only has high efficiency,but also has high accuracy.

The Segmentation Method Based on Fusion Algorithm of Transition Region Extraction for Coronary Angiograms

“…Local Complexity Method. Local complexity is used to extract transition region [8]. Let ( , ) f i j be gray distributed function defined on M N × image size, ( , ) i j S ∈ , S represents the integer set of spatial coordinates of the pixels.…”

A Comparison of Standard One-Step DDA Circular Interpolators with a New Cheap Two-Step Algorithm

“…Finally, Figures 4,5,6, and 7 present numbers of correct bits as a function of , for = 2 and = 2 2 +3 and for = 24 and = 32, respectively. Presented figures clearly show that the proposed algorithm (26) yields greater number of correct bits in comparison to algorithm (11).…”

“…One of most popular methods for generation of circles and arcs is known as digital differential analyzer (DDA). Digital circular interpolators (or angular sweep generators) based on DDA approach are widely used [2][3][4][5][6]. There are many papers where characteristics research results of such interpolators are systematized [7,8].…”
