Abstract - There have been several studies done to
The data is recorded along with the stepper motor on the SD card, which is inserted in the SD card module. The scanning mechanism is performed well to get the objects precise distance measurements through the scanning region. The main control unit of the project is the Arduino Nano, which directs the movement of the starter motor and organises the data collected on the SD card. The data is collected as a 3D point cloud, which is then uploaded to the mesh LAB using it to reconstruct it as a 3D model.
improve the technology of 3D scanning, like the source used to scan or the scanned 3D model, which undergoes several rectification procedures before being made into a complete error free model, but there are very few projects that automate the 3D scanning process. Here, we use the Arduino NANO along with a distance sensor to automate the 3D scanner on a small scale. This can be used in many industries to reduce the time consumed to re-design a product or to create a 3D model of an existing object. With this project, we can reduce or increase the time needed to scan based on the number of details needed. Key Words: 3D Scanning, Design, Point cloud
1.INTRODUCTION The current market for 3D scanning in India is growing, with various types of 3D scanners on the market. But the only issue with them is that they require human labour, and their cost is high. This 3D scanner project uses an Arduino NANO and an IR distance sensor to digitalize physical objects. It uses triangulation principles and mesh software. The open-source nature and affordable components of the project exemplify innovation with purpose, demonstrating the potential of 3D scanning in the Indian context.

Fig -1: Working block diagram
The 3D scanner has a simple working mechanism that comprises an Arduino Nano, an IR distance sensor, an SD card module, and a stepper motor. The Arduino Nano is uploaded with the program, which is used to coordinate the hardware components in the 3D scanner. The stepper motor serves as the scanning mechanism, with the Arduino controlling the movement across the area of activity. The stepper motor movement is controlled by delivering a certain pulse sequence that causes it to rotate progressively. This enables fine angular control, allowing the scanner to collect detailed data about the object's surface geometry. The stepper motor is controlled by the Arduino to increase in small increments during the scanning process. The IR distance sensor gathers the information by reflecting on the form and contours of the item and measuring the distance between the sensor and the object.

3. METHODOLGY We faced difficulties throughout our project, especially in the sensor's calibration phase and the last steps of achieving the design. We had trouble during the sensor calibration stage since the sensor was positioned incorrectly, which resulted in warped 3D point models. We verified the accuracy of our scanned data by contrasting the reconstructed 3D model with the actual object in order to reduce such mistakes. We enhanced the scanning performance and fidelity by repeatedly adjusting the calibration and design settings, guaranteeing more accurate outcomes. The final design acquisition process was less of an issue we had to deal with head-on and more of an approach. We were now finished with all the required steps. However,
