中文拼音 [lǜguāngyīnshǔ]
濾光因數
英文
filter factor-
So, in this section, a double - passage 4f wavelet filtering optical system is put forward, combining with the visual computation theory. the dog wavelet function is selected in the filter system, and the output images are just the expected, hi this part, an optical - electrical mixed system model is also mentioned, which has the advantages both in optical processing and digital processing system, such as real - time > intelligence
因此，文章在這一部分提出了一個雙通道4f小波濾波光學系統，並結合視覺計算理論，選擇了適合的小波母函數? ? dog函數製成濾被模片，對輸入圖像進行了不同尺度下的信息提取，得到了期望的輸出。But the standard mc has some shortcomings : firstly, the standard mc picks up isosurfaces by threshold, however, threshold segmentation is invalid for picking up tissues or organs from some medical images ; secondly, the standard mc pocesses cubes one by one, that is to say, all the cubes will be checked, and the algorithm spents 30 % - 70 % of time to check the null units, so we need a reasonable data structure to travel the space data and accelerate the checking or filting of null units ; thirdly, the standard mc has a large scale of triangles, normally, the tissue or organ reconstructed includes hundreds of thousands so much as millions of triangles, this means it hardly to execute real - time rendering or interaction ; lastly, the standard mc can not get the very smoothly surface mesh, and there will be some unexpected accidented cases, especially in the case of big errors in oringinal data
但是標準mc演算法存在較大的問題:標準mc演算法實質上是通過閾值分割來提取等值面，閾值分割對某些醫學圖像的組織或器官的提取難以得到較好的效果;標準mc演算法是逐個移動立方體來進行處理，就是說對所有的立方體都要進行一次檢測，演算法執行中30 % ~ 70 %的時間用在對空單元的檢測上，因此需要有一種合理的數據結構對空間數據進行有效的遍歷，以加速對空單元的檢測和過濾;標準mc演算法產生了大量的三角面片，一般重建的組織或器官包含數十萬甚至上百萬的三角面片，難以實現實時的繪制和交互操作;標準mc演算法得到的表面網格並不光滑，會有一些不期望的凹凸，特別是在原始數據有較大誤差的情況下尤其突出。Digital inputs are processed by fpga after being isolated by photocouplers. the results of digital inputs saved in fpga are read by tms320lf2407 periodically. the digital outputs being written to fpga are used to control empcs after being isolated by photocouplers and driven by darlington transistors
由於數字量的路數較多，因此採用了fpga進行擴展和簡單處理，數字量輸入通過光電隔離後送給fpga進行軟體濾波，其結果由tms320lf2407定時讀取； tms320lf2407輸出的數字量先送給fpga ，再由fpga經過光電隔離和功率驅動後去控制機電式功率控制器。And then, the different demands of position detecting on different light source and different distance are discussed. the different effects of position detecting on different circuit parameters and different center - filter frequencies are compared experimentally. after analyzing the factors that influence the speed and the precision of position detecting, the paper put forward the improving measures
本文對不同環境光照和不同測試距離下的位置測量要求進行了探討，對不同的電路匹配參數和不同濾波中心頻率的位置測量結果進行了實驗比較，認真分析了影響位置測量響應速度和精度的因素，提出了提高psd器件的抗雜光干擾能力和位置測量精度的措施。分享友人
