## 1 Introduction  
Three-Dimensional scanning is a process of collecting digital data on the shape and appearance of a real-world object or environment. These data can then be used to create a highly accurate and detailed digital replica, or 3D model, of the original object or environment. Three-dimensional scanning has a wide range of applications, from manufacturing and product design to entertainment, healthcare, and cultural heritage [1; 2; 3; 4; 5; 6; 7; 8]. One of the key benefits of 3D scanning is the ability to quickly and accurately capture the geometry of real-world objects and environments, allowing for the creation of digital models that can be used for a variety of purposes. Three-dimensional scanning can be used in a variety of industries, including manufacturing, architecture, and film and game development, among others, to create detailed and accurate digital representations of objects, spaces, and people. Another advantage of 3D scanning is its ability to automate and streamline various processes and workflows. For example, in manufacturing, 3D scanning can be used to quickly and accurately inspect and measure parts for quality control, reducing the need for manual inspection and improving efficiency. In the entertainment industry, 3D scanning can be used to create digital assets for films, games, and virtual and augmented reality experiences, allowing for more efficient and cost-effective production [9; 10; 11]. However, there are also some disadvantages to 3D scanning. One of the main limitations is the cost and complexity of the equipment and software required for 3D scanning, which can make it difficult for some individuals and small businesses to adopt the technology. In addition, the accuracy and quality of 3D scanning can be affected by factors such as the type of object being scanned, lighting conditions, and the environment. Moreover, there may also be privacy and security concerns associated with 3D scanning, particularly when scanning people, and it is important to be aware of and address these issues when using the technology [12; 13]. Cultural heritage is an important area where 3D scanning is being used. Many museums and historical sites use 3D scanning to create digital replicas of valuable artifacts and historical structures. This can help to preserve these objects and make them more accessible to the public. Additionally, 3D scanning can be used to create virtual tours and interactive exhibits, which can be a valuable educational tool. The process provides a complete and immersive representation of heritage objects, allowing for virtual exploration, analysis, and preservation. It also enables sharing of cultural heritage with a wider audience, making it accessible for research, education, and promotion purposes. Furthermore, it serves as a valuable backup in case of natural disasters, theft, or degradation of physical artifacts [14; 15; 16]. Three-dimensional scanning technology has come a long way in recent years, and there are now many different types of scanners available on the market. Some of the most common types of scanners include structured light scanners and laser scanners. Each of these types of scanners has its own advantages and disadvantages, and the choice of scanner depends on the specific application and the type of object or environment being scanned. The recent introduction of portable, handheld, 3D scanners adds even more abilities to successfully utilizing these devices in field applications [17]. The benefits of portable 3D scanners include versatility, as they can be used in various settings and environments. They are also portable, allowing for easy transportation and use on-site. In addition, these scanners often provide high accuracy results, making them suitable for use in industries such as engineering, construction, and product design. They are also efficient, capturing detailed 3D data quickly and increasing productivity. Portable 3D scanners are often cost-effective, providing a good return on investment compared with traditional 3D scanning methods.
