These machines should visually recognize surrounding objects and machines and finally decide which manufacturing disciplines, to be applied on the object. The present work is an effort to accelerate achieving this purpose. In this paper we focused on the 3D recognition process using VUDJOOD algebra theory. 3D Rotary Raster Photogrammetric Scanner (3D RRP Scanner) is designed and built at the Machine Tools Control lab of IUST. This scanner is used to generate the points-cloud of objects. Then these points-clouds are checked in the VUDJOOD equations. Finally the object which has the most overlapping with the points-cloud is recognized as the desired object. Objects identifying Algorithm has been studied for a few objects with simple geometry using the experimental tests. Dimensional accuracy of detection results is acceptable.

Introduction In recent years, many researchers have presented different methods for identifying three-dimensional objects. The ultimate goal of identifying three dimensional objects is access to technology of making robot eyes that acts Similar to the human eyes. Most studies are based on image processing of 2D image and artificial neural networks [1,2,3,4,5]. Alternatively, it is possible to estimate the 3D object shape from its already available various 2D views. Moreover, the object can be viewed from any angle regardless of the acquisition process, and displayed through standard rendering techniques. Another source of information to capture 3D object shape is the direct 3D information acquired actively by laser range scanners or other coded light projecting systems. Such 3D data acquisition systems can be very precise, but have several drawbacks [7-19]. VUDJOOD algebra is a mathematical method that describes a domain or region. The application of visual artificial intelligence in manufacturing will be the next developmental step in production technology. Operators in this field will be universal humanoid robots that can visually recognize surrounding objects and machines. These robots will work with mathematical models of the surrounding objects and machines. VUDJOOD algebra can accelerate the development of autonomic-acting machines and provide a tool for shape manufacturing [6]. It has been shown that body can be described by mathematical operations. We know that all machine parts are information carriers programmed to perform a designer-defined task. Machines are mechanical computers, and the manufacturing process is a method of programming. The human environment is full of bodies that can be influenced and changed by other humans or machines. Every small relative movement or change must be calculated by brain internal virtual reality. Because of this internal virtual reality, a person knows what would occur. The result of this calculation capability is visual intelligence. To create intelligent machines that are like humans, the mathematical laws of imagination must be fully understood. VUDJOOD algebra provides a fitting mathematical tool for comprehension and can be applied to different manufacturing disciplines. Shape manufacturing is not a human invention. Since the beginning of time, nature has created bodies with the characteristic laws of VUDJOOD algebra [6]. In this paper, we present our opinions on VUDJOOD algebra theory from the viewpoint of 3D object identification. Firstly, we analyze characteristics of VUDJOOD algebra that are adapted to the study of object identification. Secondly, we present our opinions on object identification. Finally, we introduce our work on the points- cloud of three-dimensional scanning device which is used for identification i.e. Coordinates of points checked out in the VUDJOOD algebra equations of geometrical models. 2.
