Abstract

A non-contact morphology system for 360° object surface measurement, involving a CCD camera, a line-structured light source and a rotated platform has been developed based on the triangulation method. The system parameters have been optimized to meet the requirement of system specification, such as range scope, range resolution, measurement accuracy and the shadow effect. For sampling the whole object surface, the CCD camera captures one frame after the motor rotates every step of 1.5° under the control of a computer. The mapping relationship among the 2-D images and 3-D surfaces from the different views and orientations can be developed by means of the spatial geometric correspondence. Moreover, the intensity, color and texture information from the CCD intensity image can be affixed to the entire 3-D surface with OpenGL. The system records more than 160000 facial coordinates with a dynamic resolution of approximately 1 mm in 60s. Examples of application of the system are given.
