Mechanical Design for Stable and Robust Total Color Appearance Capture: Advancements and Implementation

With the escalating demands for rendering technology, exclusive reliance on rendering programs is no longer sufficient. The collection of surface information pertaining to real-world materials has become a crucial aspect of computer graphics. The acquisition of material surface information is pivotal in the fields of digital reconstruction and virtual reality. In this article, we introduce a material acquisition device that employs multiple cameras and lights. This device utilizes a combination of multiple cameras and lights to capture objects from various angles and lighting conditions, resulting in more comprehensive and realistic material surface information. Specifically, the device features multiple cameras and strategically placed lighting. Four cameras are positioned at 10∘, 35∘, 60∘, and 85∘ to capture various aspects of the surface of the object while 24 point lights are placed in three layers of the hemisphere at 10∘, 35∘, and 60∘ with eight lights per layer spaced 45∘ apart. This approach facilitates the acquisition of rich and diverse material surface information by integrating multiple perspectives and lighting conditions.
