This new method has the capability of calculating complicated 3d grain burning surface. dealing with evolving interface of complicated material and topology change ( splitting. breaking. merging ), based on level set method and burning surface process law. this technique can get accurate area of burning surface each moment and data of geometrical structure that provide access to examination of grain change in the srm working process. 2
結合固體火箭發動機燃面推移規律，在等值面函數法基礎上開發的裝藥燃面演算法能夠成功計算任意復雜三維裝藥燃面，並且具有處理復雜物質邊界及其拓撲結構發生變化（如分裂、破碎、合併）的能力，能夠準確計算出發動機工作過程中各個時刻裝藥的燃燒面積，同時輸出裝藥幾何構形數據直觀地觀察裝藥的變化情況； 2 -
In the research, the system captures real - time images based on the sdk, and saves the image data into buffers which are created by the system. the important and primary parts are got using the programs which are designed to process and analyze the image data in the buffers, and the geometrical features such as area, perimeter, moment invariants and fourier descriptor, are measured. the parts are classified according to the threshold of each geometrical feature with the image database
課題研究中，在設計的試驗平臺上，通過攝像頭和sdk開發包對零件進行實時圖像採集，並將其存入開辟的數據緩沖區內;由設計的圖形處理模塊對緩沖區內的數據採用各種演算法進行分析處理，形成研究中感興趣的重要圖像;調用圖像識別判斷模塊，主要提取了零件的周長，面積，慣性矩，傅立葉描繪子等形狀特徵參數，根據定義的識別函數，並結合圖像數據庫，進行零件識別或缺陷檢測。
