三维形貌及颜色纹理的快速获取方法

为了在黑白摄像机中快速获取场景的三维形貌与颜色纹理, 提出了绝对相位测量结合主动彩色照明的方法.首先向物体投影并拍摄两幅相移为1/3周期的条纹和一幅周期有微小差别的条纹图;然后分别向物体投射光强为给定强度的白、红及绿照明光, 并拍摄图像.用改进的相移法求解第四幅图像与第一、第二幅变形条纹图中的相位;用改进的傅里叶变换法求解第四幅图像及第三幅变形条纹图中的相位;然后得出绝对相位值.最后利用第四幅图像与第五和第六幅图像求出场景反射的蓝色分量, 并根据色度学原理恢复出场景的颜色纹理.实验表明, 该方法在保证三维测量准确度的同时获得了高质量的颜色纹理, 实现了30fps的三维数据及颜色纹理采集速度.

Abstract

A method for fast capturing three-dimensional shape and color texture with the black and white camera was proposed based on the absolute phase measuring and active color lighting. First, two stripes with 1/3 period phase shift and one stripe whose period is slightly different with the two stripes are projected. The deformed stripes are captured simultaneously. Then, patterns with the specific color of white, red and green are projected on the objects respectively and the images are captured. Second, by using the fourth image, the first and the second deformed stripes, phase distribution of the stripe is obtained with improved phase shifting method. The phase distribution of the other stripe is obtained with improved Fourier transform method by using the fourth image and the third deformed stripe. Then, the absolute phase distribution is obtained. Finally, by using the fourth image, the fifth and sixth image, the reflected green component of scene is obtained. According to the principle of the colorimetry, the color texture of scene is retrieved. The experimental results show that the high quality color texture and the high measurement accuracy for three-dimensional shape can be achieved simultaneously with the proposed method. The recording speed of the three-dimensional data and the color texture can reach to 30 fps.
