Analysis of the structure material of the bronze object in 3D models point cloud

Abstract

The study deals with experimental research of the material of a bronze work of art. It characterizes the visual properties of the metallic material for perception by the human eye and lists the expected undesirable properties that may affect the quality of reproduction of the work in a 3D model of point clouds. The text also presents image capture for the use of the photogrammetry method. This method was used for 3D modelling of a real object in the exterior. The human eye is a significant environment of the perception of the object and the 3D modelling process. Lighting conditions also significantly affect the quality of the captured image and its processing into a point cloud. The results of the image quality of the original art transferred to the 3D environment reveal the essential attributes of the work when capturing the image. The experiment aims to determine the fundamental aspects influencing the image work with metallic objects and its conversion in the form of point clouds into 3D models for use in virtual reality. Attention is paid to the quality and complexity of processing the reproduction of the object into a point 3D model. And the influence of the properties of the metallic material and the surrounding exterior environment on 3D modelling by photogrammetry.
