Realization of kf by using c language faced on c196 in navigation computer 使用c196語言于車載導(dǎo)航計算機(jī)上實(shí)現(xiàn)導(dǎo)航計算中的卡爾曼濾波計算。
The front panel of the airplane ' s navigation computer showed the currently selected navigation fix and a course - deviation indicator 飛機(jī)導(dǎo)航儀的前部面板顯示了當(dāng)前選中的導(dǎo)航坐標(biāo)和路線偏移指示器。
Researches are mainly focused on the following aspects : developed navigation computer based on microcontroller 80c196kc , reduced the cost of the device of vehicle navigation 本文首先討論了用80c196kc單片機(jī)為核心開發(fā)出車載導(dǎo)航計算機(jī),以替代原用pc104 ,極大地降低了車載設(shè)備的成本。
A flight simulator is successfully designed in order to solve the problem that the integrate navigation system ' s core navigation computer couldn ' t perform system dynamic trial in static state 由于導(dǎo)航計算機(jī)的航空實(shí)驗難度高、耗費(fèi)大,而靜止?fàn)顟B(tài)下導(dǎo)航系統(tǒng)不能向?qū)Ш接嬎銠C(jī)提供動態(tài)參數(shù),無法滿足導(dǎo)航計算機(jī)動態(tài)仿真試驗的需要[ 1 ] 。
The paper first generalizes basic substance and mechanism layout of sins . the hardware component and function of the embedded navigation computer control system based on pc / l04 bus technique is introduced . the paper majors in designing and realizing software of the sins based on the dos operation system 本文首先簡要地分析了慣導(dǎo)系統(tǒng)的基本工作原理,給出了慣導(dǎo)系統(tǒng)的機(jī)械編排,介紹了基于pc / 104總線技術(shù)的嵌入式導(dǎo)航計算機(jī)控制系統(tǒng)的硬件組成、結(jié)構(gòu)和功能。
Image processing system is a very important part of mini unmanned helicopter , which mainly dealing with how to detect the object and supply the navigation computer with location information of the object . however , the varied background and the moving of the camera make the image processing become difficult . to solve these problems , this thesis introduces an object detection algorithm based on contour retrieving , template match and hu moments invariant 硬件組成詳細(xì)探討了系統(tǒng)結(jié)構(gòu),并對所采用的ccd攝像機(jī)、視頻采集卡等硬件單元作了描述;在軟件設(shè)計中,首先對不同操作系統(tǒng)環(huán)境下的視頻捕獲做了討論;接著,重點(diǎn)研究了針對機(jī)載攝像機(jī)拍攝圖像的目標(biāo)檢測方法,提出并實(shí)現(xiàn)了基于模板匹配和不變矩的目標(biāo)檢測算法,以及基于機(jī)器學(xué)習(xí)的目標(biāo)檢測算法。
