# Enhancing Furniture Manufacturing with 3D Scanning
## 2 An Up-To-Date Review of 3D Scanning in the Furniture Industry  
[PERSON] et al. (2023) reviewed 3D scanning in Industry 4.0 applications [10]. Similar research is presented in the study by [PERSON] et al. [11]. These studies highlighted that 3D scanning is essential for manufacturers who need accurate dimensional inspection, virtual image analysis, and fast physical prototype manufacturing. Both studies discussed the potential of 3D scanning for the industrial sphere with the development of the workflow process of 3D scanners for industrial requirements. [PERSON] and co-authors identify and discuss sixteen main applications of 3D scanning from an industrial perspective but do not give specific furniture industry applications. Three-dimensional scanning of furniture in scientific documents involves the use of technologies such as Terrestrial Laser Scanning (TLS) [12], custom trolley-based systems with laser scanners [13], and advanced methods such as reversible jump MCMC for structural element identification [14]. Additionally, repositories such as 3D-FUTURE provide richly annotated 3D furniture shapes for research purposes [15]. Recent advances include Mesh_CA, a method that combines neural networks and differentiable rendering for 3D object reconstruction without 3D supervision data [16]. These approaches enable the generation of accurate 3D furniture models, aiding in tasks such as furniture classification, structural element identification, and texture recovery for comprehensive research in areas like 3D modeling and object pose estimation. [PERSON] and [PERSON] [17], [PERSON] [18], and [PERSON] [19] described 3D scanning technology for restoring and protecting ancient furniture. These studies concluded that digitalization significantly enhances restoration quality when combined with modern manufacturing methods. Three-dimensional scanning also has technological applications in the furniture industry. [PERSON] et al. [20] used 3D scanning to measure the instability of pinewood. In this study, 3D scanning was used as a metrology tool to evaluate the sustainability of wooden furniture elements for robotic montage. [PERSON] et al. [21] explore the relationship between cutting parameters, material properties, and part geometry in CNC machining and its impact on the quality of furniture parts. Two methods are presented to evaluate surface flatness and roughness, including manual and automated measurement techniques. The authors confirmed that 3D scanning helps automate manufacturing processes to improve the quality of components. [PERSON] et al. [22] present a digital close-range photogrammetry method as an inexpensive digitization technique used for abstract-shaped real objects, with the ultimate goal of being unique or mass production of the object using CNC machining. Although photogrammetry is a type of 3D scanning, it is generally not used in industrial applications. However, because of the growing need to digitize real-world objects for manufacturing in the shortest time and at a price as low as possible, such as ornamental objects or various components of furniture where the precision of the resulting 3D model is less demanding, it can be used for this purpose and only for large objects. Photogrammetric methods cannot be used to scan small and precise objects [23]. [PERSON] et al. [12] conducted one of the first studies focusing on 3D scanning challenges for various complex surfaces of furniture using hand-held and stationary scanners. This is one of the first papers to research problems for 3D scanning different complex furniture surfaces using hand-held and stationary 3D scanners. Different materials were selected as experimental objects through the hand-held laser three-dimensional scanner mapping experiment, and three-dimensional scanner measurement technology was used to quickly transform the scanned image into one data point after another.
