【摘要】：平面度測量是指對待測平面的平面度誤差值的測量。平面度測量廣泛應用在機械工程安裝、建筑業(yè)施工過程以及大地測量等領域。特別是在建筑施工過程中的內部裝修中,隨著施工要求的提高,越來越需要一個可以實時提供的共同施工基準。平面度測量的傳統(tǒng)手段,或者由于結構過于復雜,或者由于測量范圍有限,或者由于測量效率太低,已經(jīng)不能滿足我們的實際需求。因此本文旨在開發(fā)一種結構簡單、中等精度、可以實現(xiàn)快速測量的嵌入式平面度測量系統(tǒng)。本文調研了平面度測量的原理和常規(guī)方法,分析了工業(yè)現(xiàn)場對平面度測量的需求和常規(guī)測量手段的不足,在此基礎上提出了一種基于點陣結構光的平面度測量方法,設計了一種結構簡單、成本低廉、精度在0.2mm以內、在1m工作距離處測量范圍為0-48.79mm的嵌入式快速平面度測量系統(tǒng)。主要工作分為三個部分：第一,介紹了測量系統(tǒng)的總體設計方案,并進行了嵌入式快速平面度測量系統(tǒng)的搭建。測量系統(tǒng)以激光器和正交光柵為點陣結構光生成器,以USB相機為圖像采集單元,以ARM開發(fā)板為控制處理單元。第二,介紹了基于點陣結構光的平面度測量方法的原理,建立了測量方法的數(shù)學模型。在此基礎上,設計了圖像處理算法和數(shù)據(jù)處理算法。然后,進行了算法的實現(xiàn)和嵌入式軟件的開發(fā)。第三,設計并進行實驗,對測量方法的準確性和測量系統(tǒng)的精度進行了驗證。進行計算機仿真實驗,驗證光斑中心的定位算法的準確性；進行基于PC平臺的,標準平面位移的測量、白板平面和紙板平面平面度的測量等實驗驗證測量中近似方式的合理性,測量方法的有效性和測量方法對不同表面特性的待測平面的適用性；進行基于嵌入式快速平面度測量系統(tǒng)的,標準平面、白板平面和紙板平面平面度的測量實驗,驗證測量系統(tǒng)的測量精度和準確性。
[Abstract]:Flatness measurement is the measurement of flatness error. Flatness measurement is widely used in mechanical engineering installation, construction process and geodesy. Especially in the construction process of interior decoration, with the improvement of construction requirements, there is an increasing need for a real-time common construction benchmark. The traditional methods of flatness measurement either because the structure is too complicated or because the measurement range is limited or because the measurement efficiency is too low can not meet our actual needs. Therefore, the purpose of this paper is to develop an embedded flatness measurement system with simple structure, medium precision and fast measurement. In this paper, the principle and conventional method of flatness measurement are investigated, and the demand for flatness measurement and the shortage of conventional measurement methods are analyzed. On this basis, a flatness measurement method based on lattice structured light is proposed. An embedded fast flatness measurement system with simple structure, low cost, precision within 0.2mm and measuring range of 0-48.79mm at 1 m working distance is designed. The main work is divided into three parts: first, the overall design of the measurement system is introduced, and the embedded fast flatness measurement system is built. The measuring system uses laser and orthogonal grating as lattice structure light generator, USB camera as image acquisition unit and arm development board as control processing unit. Secondly, the principle of flatness measurement method based on lattice structured light is introduced, and the mathematical model of measurement method is established. On this basis, image processing algorithm and data processing algorithm are designed. Then, the implementation of the algorithm and the development of embedded software are carried out. Thirdly, the accuracy of the measurement method and the accuracy of the measurement system are verified by designing and carrying out experiments. Computer simulation experiments were carried out to verify the accuracy of the algorithm for locating the center of light spot, and the measurement of standard plane displacement based on PC platform, the measurement of white board plane and paperboard planeness, and so on, were carried out to verify the reasonableness of the approximate method in the measurement. The validity of the measurement method and the applicability of the measurement method to the plane to be tested with different surface characteristics, the measurement experiments of the standard plane, white board plane and paperboard planeness based on the embedded fast flatness measurement system are carried out. Verify the accuracy and accuracy of the measurement system.
