The whole frame used in this paper is that, first, by using video card, we get a series of b - scan images, then delete the noise in this images. secondly, draw the outline of interesting object in each image by manual, through clicking mouse on screen. thirdly, reconstruct 3d - image using 2d contour
本文圖像處理採用的總體方案是:首先,運用圖像採集卡從b超儀獲取一系列超聲斷面圖像,然後對超聲圖像進行去噪預處理,再通過人機交互的方式,手工勾畫出各層圖像中感興趣目標的輪廓線,並運用三維重構技術進行三維重構,最後運用opengl將三維圖像顯示出來。Firstly, on the base of analyzing psk ' s theory and audio - card ' s constitute and data transfers, bdpsk and qdpsk soft - modulation and soft - demodulation systems based on audio - card are studied and implemented, including generating digital carrier sequence, synchronizing carrier, designing filter, sampling and judging, etc. the system adopts coherent demodulation method, synchronizing carrier adopts costas loop
本文首先分析了調相信號調制解調的基本理論和多媒體計算機( mpc )聲卡組成原理及數據傳輸等方面的內容,然後研究並實現了基於計算機聲卡的bdpsk和qdpsk信號軟體調制解調系統,內容包括數字載波序列的產生、載波同步、濾波器設計,信號的抽樣判決等。And in allusion to the shortcomings on the fitting of noises by least square, a new procedure is presented to modify the estimations of model parameter of the noise. it can control the effects of the correlation noise of except for first order self - correlation noise. using the model the error of gps / ins integrated navigation system is estimated
再次,針對卡爾曼濾波方程的前提條件不滿足而影響導航系統的精度的問題,應用時間序列分析理論提出了一種改進的噪聲模型參數估計演算法,對此演算法進行建模,模擬結果表明,該演算法能有效的控制一階自相關特性以外的噪聲對參數模型估計的影響,提高卡爾曼濾波精度。Then, a multi - element linear transducer array system based on the high - speed data acquisition card was designed and realized photoacoustic imaging by it firstly. compared to other existing technology and algorithm, the pa imaging based on transducer array was characterize by speediness and convenience
其次,在高速採集卡的基礎上設計研製了基於多元線性陣列探測器系統的快速光聲層析成像裝置,首次實現了基於多元陣列探測器的光聲成像。According to the principle of lower cost, higher reliability, the design completes much work. the contents of project are as follows : ( 1 ) pic micro - controller which is lower - power and lower price is the core of control device. the whole circuit realizes the functions of collecting pulse, keeping data, driving electric machinery valve, reading and writing ic, detecting power supply, sound alarm and liquid crystal display
設計依據低成本,高可靠性的原則完成了以下工作: ( 1 )用功耗低、價格便宜的pic系列單片機作為控制裝置的核心,控制裝置的硬體電路實現了脈沖採集、數據存儲、電機閥驅動控制、 ic卡讀寫、電源檢測以及聲音報警和icd液晶顯示等功能。The beijing karmel culture art development center is engaged in the domestic and foreign large - scale displays, the demonstration design manufacture, the display equipment manufacture sale and rental, the opening ceremony booth build, the opening ceremony cuts the ribbon, the etiquette service, the military band performance, the basket of flowers bouquet of flowers, the furniture rents, the celebrity manages, the dragon dance lion dance, the imposing percussion instrument, the light sound, the lift - off balloon, the balloon releases for flight, the fireworks salute, the cartoon arched entrance, the model manufacture, the sash colored flag, the scroll theater curtain, balloon printing, each kind of orchestra, the scene arrangement, the chinese dress rents, stage dance america, the video frequency projection, the sound amplifies, simultaneous interpretation and so on a series of services
