How to Scan 3D Objects with David Laserscanner Pro 3.0 L
David Laserscanner Pro 3.0 L is a software that allows you to scan 3D objects using a webcam, a laser and a corner as background. It is a professional solution that can capture high-resolution and accurate scans of complex shapes and textures. In this article, we will show you how to set up and use David Laserscanner Pro 3.0 L to scan your own 3D objects.
What You Need
- A PC that meets the system requirements of David Laserscanner Pro 3.0 L. You will need at least 4 free USB ports, including 2 USB 3.0 ports for the cameras.
- A webcam that can capture HD video. You can use the built-in webcam of your laptop or an external one.
- A line laser that projects a visible red or green line onto the object. You can buy a suitable laser module from the David website or use a laser pointer.
- A corner as background. You can use any corner in your room or make one with two cardboard panels.
- A tripod or a stand to mount the webcam and the laser.
- A turntable to rotate the object. You can use the TT-1 turntable from David or any other turntable that can be controlled by the software.
- A calibration panel to calibrate the camera and the laser. You can use the glass panel that comes with the SLS-3 kit from David or print your own panel from the software.
- A USB dongle to run the software. You will receive it when you buy the software license from David.
How to Set Up
- Install David Laserscanner Pro 3.0 L on your PC and insert the USB dongle into a free USB port.
- Connect the webcam, the laser and the turntable to your PC using USB cables. Make sure the webcam and the laser are on the same side of the corner.
- Mount the webcam and the laser on a tripod or a stand and adjust their positions so that they point at the corner. The webcam should be parallel to the corner and the laser should be at an angle of about 30 degrees to the corner.
- Place the calibration panel on the turntable and align it with the corner. The panel should be perpendicular to the webcam and parallel to the laser.
- Launch David Laserscanner Pro 3.0 L and select "Structured Light Scanning" mode.
- Select your webcam as the camera device and adjust its settings such as resolution, exposure and focus.
- Select your laser as the line device and adjust its settings such as brightness, contrast and threshold.
- Select your turntable as the rotation device and adjust its settings such as speed, direction and steps.
- Click on "Calibrate Camera" and follow the instructions on the screen. The software will capture several images of the calibration panel and calculate the camera parameters.
- Click on "Calibrate Laser Plane" and follow the instructions on the screen. The software will capture several images of the laser line on the calibration panel and calculate the laser plane equation.
How to Scan
- Remove the calibration panel from the turntable and place your object on it. Make sure it fits within the scanning area defined by
the corner, the webcam and
the laser.
- Click on "Start Scanning" and wait for
the software to capture
the images of
the object from different angles.
The software will project
a structured light pattern onto
the object and record
the deformation of
the pattern caused by
the object's shape and texture.
- Click on "Stop Scanning" when
the scanning is complete.
The software will process
the images and generate
a point cloud of
the object.
- Click on "Shape Fusion" to fuse
the point cloud into
a mesh model of
the object.
You can adjust
the settings such as resolution, smoothness and hole filling to improve 51082c0ec5
