Wykorzystanie techniki światła strukturalnego do trójwymiarowej inwentaryzacji obiektów naturalnych
Using structured light technique to three-dimensional inventory of natural objects

Summary/Abstract: The article presents the possibility of a three-dimensional inventory of natural objects using structured light technology. In this work tested the first Polish mobile scanner MantisVision which is used to work with small and hardly accessible objects in variable lighting conditions. The article describes in details the process of accurately reproducing the bone elements of farm and marine animals. The method used in this work is non-invasive, it allows to increase the level of details and accuracy of digital documentation with high spatial resolution generated model. The scanning does not require good lighting, and allows off-road control the quality of the data. Fast data acquisition facilitates measurements of dozens positions within few minutes, what reduce the residence time of the measurement team on the site. Scanners using a structural light formed on the initiative of replacing one of the cameras in stereoscopic scanner by an active element, which is a projector or laser. This solution makes it easier to find the corresponding image points, which is a serious problem for passive systems. This technique is widely using for 3D scanning, in many areas of life. Devices that using a structural light fill the gap between cheap commercial scanners with insufficient precision, and exclusive ones, where the very high price stops the possibility of their use.
