3d Scanner Advantages And Disadvantages

1. Introduction
A 3D scanner is a device that analyzes an object and its surrounding environment with the aim of collecting data related to the shape, dimensions, and other exterior features and appearance (such as color, normal map of the surface, etc.). The collected data are used to reconstruction and build of the point clouds model in a wide range of industries and applications such as design and manufacturing, reverse engineering, robotics, medicine, quality control, cinema, entertainment industry (such as Kinect sensor), etc. [1]. Generally, three-dimensional scanners are divided into two groups of contact and non-contact scanners, according to the necessity of the sensor's contact with the surface of the piece, and at the meanwhile, non-contact scanners themselves are classified into active and passive groups based on the

Based on these categorizations, we see a variety of techniques and methods to implementing a 3D scanner with its own advantages and disadvantages [2]. According to the development of three-dimensional measurement methods over the past two decades, along with the acceleration of scanning operations and the accuracy in measuring and significant development of their application in a wide range of fields such as robotics, we have seen an increase in the amount of information obtained (point clouds) from the 3D scanner as the output of the scan operation. This raises restrictions on data management, processing, data transfer, data storage, or even the development of real-time
