Abstract


With the computer technology and the rapid development of measurement techniques , three-dimensional dynamic measurement technology in many fields of applications more widely, such as industrial automation field line detection, object deformation measurements. Existing dynamic three-dimensional measurement methods can be divided into two types , one is the only three-dimensional reconstruction of a single image , and the other is the use of multiple images of three-dimensional reconstruction . This selection of three-dimensional reconstruction of a single image , and this dynamic measurement system of the key issues were studied. This paper presents two single image applied to dynamic measurement method of three-dimensional reconstruction : based on digital camera technology and image reconstruction of single color raster -based three-dimensional reconstruction of a single image . Thesis work and research are: 1 . In the original three-dimensional measurement system based static proposed under the single color raster -based 3D image reconstruction method to solve the dynamic measurement of the key issues raised image encoding and decoding way through the most highlights and darkest points determined to achieve the cycle is divided , propose a new camera based on the most appropriate method of analysis highlights the color of the judge , resulting in all points of the phase cycle phase cycle to achieve the solution , according to the brightness achieve cycle phase main values ​​solving complete solution to complete all phases point algorithm . (2) completed a raster -based color-coded three-dimensional reconstruction of experimental single image can be realized on the object plane and the more complex the solution -phase and three-dimensional reconstruction, verified by experiment the feasibility of this method to obtain a more satisfactory experimental results and offline processing of data to achieve a dynamic measurement process. By implementing the three-dimensional reconstruction of a single image , to achieve real-time dynamic three-dimensional measurement system basis.
