BTM one – Compact Industrial 3D Scanner

Bluelynes technology is the advanced, patented, optical technology for 3D-scanning developed by IDloop. The technology allows for a fast, high-resolution 3D-scan by using structured light. The light is projected onto a surface in a known pattern and deformed by the surface structure. By imaging the deformed light pattern with a camera, the 3D-surface is reconstructed via triangulation.

Bluelynes technology is highly customizable for different uses and can capture 3D surface details from a wide variety of capturing distances and with numerous variations in field-of-view. The resulting 3D-point cloud consists of millions of data points for the high resolution of surface details. Because bluelynes technology offers a fast scan of almost any surface, the object can even be in motion during the scan. With such flexibility in the range of parameters, it is not surprising that bluelynes technology has applications in many sectors. It has been successfully used in the high-security sector to scan biometric features, and it is also used for industrial 3D imaging–in surface inspection, reverse engineering, quality control, and inline and offline inspection.

The scanability depends on the optical properties of the surface and the measurement setup.

Reflective surfaces: Depending on the surface, changing the measurement angle may improve the measurement results. For more challenging surfaces, measurements from multiple angles or the use of a scanning spray may be required.

Transparent surfaces: Transparent surfaces typically require a scanning spray to obtain valid measurement data.

Dark surfaces: Dark surfaces can generally be scanned by adjusting the projector brightness to compensate for the lower amount of reflected light.

The scanning time depends on the selected scan mode and the computer or tablet used. A complete scan includes image acquisition, 3D data calculation, and data transfer to the connected device.

Image acquisition takes less than 0.1 seconds up to 2.1 seconds, depending on the scan mode. The longer scan mode uses more structured light patterns to achieve higher depth resolution and more detailed 3D data. The time required to calculate and transfer the 3D data depends on the performance of the connected device.

IDloop provides a range of output options, including point clouds and images. These formats are generally not directly compatible with standard CAD software and may require additional processing or conversion before they can be used in a CAD workflow.

The BTM Capture software application is provided with the scanner and can be downloaded after purchasing the device. It is designed for capturing 3D scan data and provides a range of settings, including scanning mode, projector brightness, camera gain, filter options, and output formats.
