Novel 3D shape measurement method with lower occlusion for the bottom of cavity Download: 818次
Abstract
Because the bottom of the cavity has the shadow and occlusion, the angle between the projection system and imaging system is limited. So the traditional fringe projection technique based on the principle of optical triangulation is inapplicable. This Letter presents a 3D shape measurement method of using the light tube for the cavity. The method can measure an object from two opposite views at the same time, which means it will obtain two different groups of 3D data for the same object in a single measurement. The experimental results show the feasibility and validity of the 3D shape measurement method.
