  • Leica BLK3D Portable Photogrammetry Tool

The BLK3D combines a calibrated stereo camera, measurement sensors, software, and on-device edge detection capabilities to make in-picture measurements with professional-grade accuracy. Every image captured is a complete and precise 3D measurement record. 

The BLK3D is designed to make your measurements faster and easier to take within any picture you can capture with the device. It will help you fully document your work, including as-built conditions and project progress.

Minimum system requirements Windows 8.1, 10 with 64-bit; 6 GB RAM

1) Wi-Fi® off, Bluetooth® off, flash off, screen brightness 50%.

2) Applies to 100 % target reflectivity (white painted wall), low background illumination, 25 ºC.

3) Applies to 10 to 100 % target reflectivity, high background illumination, - 10 ºC to + 50 ºC.
