How to Use the HP 3D Structured Light Scanner Pro S3 (DAVID SLS-3) for Professional 3D Scanning
If you are looking for a high-quality and versatile 3D scanner that can capture both geometry and texture of objects, you might want to consider the HP 3D Structured Light Scanner Pro S3 (DAVID SLS-3). This scanner is based on the structured light scanning technology, which projects a pattern of light onto the object and captures it with one or two cameras. The software then reconstructs the 3D shape and color of the object from the images.
The HP 3D Structured Light Scanner Pro S3 (DAVID SLS-3) is the third version of their structured light scanning product with better (HD) cameras than its predecessors â and almost certainly its competitors[^1^]. It is a modular system that comes with a projector, one or two industrial grade monochrome HD cameras, a calibration panel, a turntable, and a tripod. You can also use your own tripod or mount the scanner on a desk scan lever. The scanner works with any PC that meets the system requirements and has four free USB ports (two of them must be USB 3.0).
In this article, we will show you how to use the HP 3D Structured Light Scanner Pro S3 (DAVID SLS-3) for professional 3D scanning. We will cover the following topics:
How to set up the scanner and calibrate it
How to scan an object from different angles and merge the scans
How to apply texture to the 3D model
How to export the 3D model to various formats
How to Set Up the Scanner and Calibrate It
The first step is to set up the scanner and calibrate it. This is important to ensure accurate and consistent results. Here are the steps:
Connect the projector, the camera(s), and the turntable to your PC using the USB cables. Plug in the power adapters for the projector and the turntable.
Insert the USB dongle that comes with the scanner into a free USB port on your PC. This is required to run the software.
Download and install the latest version of HP 3D Scan Software Pro from here. Launch the software and select your scanner model from the drop-down menu.
Mount the projector and the camera(s) on the aluminum rail and slide them onto the tripod. Adjust their positions so that they are roughly parallel to each other and face the object you want to scan.
Place the calibration panel on the turntable and align it with the center mark. Make sure it is perpendicular to the projector and camera axis.
In the software, go to Calibration > Structured Light Scanner Calibration. Follow the instructions on the screen to calibrate your scanner. You will need to rotate the turntable by 90 degrees four times and capture images of the calibration panel from different angles. The software will automatically calculate the calibration parameters and save them.
Congratulations! You have successfully set up and calibrated your scanner. You are now ready to scan an object.
How to Scan an Object from Different Angles and Merge
The next step is to scan an object from different angles and merge
the scans into a complete 3D model. Here are
