鑒於此,本文給出了一種全新的測量方案:採用車輛段普遍使用的轉輪器實現被測輪對的定位;採用車軸基準探尺測定被測輪對的軸線;採用並聯式伸縮機構和旋轉測頭作為傳感器的執行機構,測定輪輞斷面的輪廓線。Abstract : in fourier transform profilometry, because of the nonlinear relationship between the irradiant incident upon a ccd dete ctor andthe voltage it outputs, it will cause phase evaluation errors. here, we ex plain the errorsource by theoretical deducing, then make a simulation. at last, a method to decrease thiserror is put forward
文摘:在傅里葉變換輪廓術中,由於ccd探測器光電響應的非線性,將在測量中引入高次項,從而對相位的求解造成較大誤差,通過理論的推導定性地解釋了誤差的來由,並用計算機進行了模擬計算,最後提出了減小誤差的方法。Secondly, in phase unwrapping to overcome the spread of wrong point, changing the patch of unwrapping phase is done to improve the correctness of it. then, the relation between the unwrapping phase and the height of reconstructed object is discussed detailedly. the data processing, algorithm analysis and reconstructing object are done for the collecting fringe image which are all based on matlab language, in all these achievements, the improvement and innovation aspect are following : a ) in order to stabilize the interference fringe, a new equivalent shifting object method is presented by using fringe stabilizing device to stabilize the interference fringe though moving object and ccd camera which fixed on a precise moving platform together, the experimental result shows the fringe drift is less than a / 20 in five minutes, and the equivalent phase shifting precision is x / 100
論文在全面闡述了光學三維輪廓位相測量術的發展、應用現狀、研究熱點及未來發展趨勢的基礎上,簡要介紹了傅立葉變換和相移位相輪廓測量術的基本原理,對兩種測量方法存在的問題及誤差進行詳細分析和比較;針對位相解包裹錯誤點的傳播問題,作者通過改變解包裹路徑來提高位相解包裹的正確性;分析討論從解包裹位相( x , y )到再現物體的高度h ( x , y )物理量之間的關系,研究相應的演算法,利用matlab平臺,對實際採集的條紋圖像進行處理和輪廓重構,其中改進及創新工作主要表現在以下兩個方面: ( a )針對干涉型結構光場干涉條紋出現的漂移抖動對相移的影響,提出了一種用條紋穩定器穩定干涉條紋,用精密移動平臺使物體和ccd攝像頭同步移動實現等效相移的方法,建立了相應的測量系統,系統的條紋穩定可以達到。The contacting measurement method with a double probe is put forward after the detailed analysis of the state - of - the - art measuring methods of the thickness of wall. firstly, the theory - profile generatrix is built, and then the movement curve of the track of joint center is constructed, which aims at making the joint center move along the movement curve and keep the fixed sensor touching the wall. the measuring sensor examines the line in its normal direction of the interior wall all the time, the data from the sensor is the thickness value of the wall
論文通過分析國內外變曲率回轉體壁厚測量的現狀,提出了雙測頭接觸式測量方案:通過構造理論輪廓母線,建立鉸鏈中心的運動曲線,使鉸鏈中心始終沿運動曲線運動,以保證固定觸頭與傳感器測頭的連線始終在內壁法線方向上,從而傳感器測頭所得的數值即為壁厚值,該方案經模擬測試實驗取得了預期效果。The result shows this measure system is very simple, performance reliable, operating convenience, and its precision approaches to 1 %. it takes an important role in large - scale measurement and in practice the new method shows stronger practicality and popularly application prospect
