A compact, all-in-one 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.
Measure in picture for fast, accurate results.
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.

A smart, simple, and easy-to-use tool for photogrammetry.
The BLK3D—similar to a smartphone in shape, size, and operation—uses advanced algorithms for edge detection and measuring within 2D pictures. The touchscreen interface is user-friendly and powerful with precise photogrammetry at your fingertips.
Multiple functions with advanced technology.
As part of an everyday kit, professionals can make faster decisions within their daily workflows—whether measuring inaccessible locations, creating floor plans, estimating building installations, documenting construction site progress or creating measurable, as-built documentation.
Access, organize, share, and store images.
Store images on the device or use USB-C or WLAN to transfer images and data to your computer. Organize your projects by tagging measurable images with searchable keywords for easy recall and share them in multiple formats.

1) Wi-Fi® off, Bluetooth® off, flash off, screen brightness 50%.
2) Multi-shot with recommended baseline length (all except 2.5 m 2D).
3) Measurement precision, accuracy, and reliability are dependent upon various factor including distance and position to object, baseline length, texture of object, light conditions, ambient temperature, calibration etc. Figures quoted assume normal to favorable conditions at close range and are subject to change.
4) Applies to 100 % target reflectivity (white painted wall), low background illumination, 25 ºC.
5) Applies to 10 to 100 % target reflectivity, high background illumination, - 10 ºC to + 50 ºC.
6) Tolerances apply to ranges from 0.05 m to 10 m with a confidence level of 95%. The maximum tolerance may deteriorate to 0.1 mm/m between 10 m to 30 m, to 0.20 mm/m between 30 m to 100 m and to 0.30 mm/m for distances above 100 m.
7) After user calibration. Additional angle related deviation of ±0.0.1° per degree up to ±45° in each quadrant.
8) A single-shot is only recommended up to a distance of 2.5 meters to the target object
9) 2D distances
10) Long 2D distances (corner to corner measurements in a 3D Image) and 3D distances
11) Multi-shot with recommended baseline length of 10% of the distance to the target object
12) Measurement precision, accuracy, and reliability are dependent upon various factors including distance and position to object, baseline length, texture of object, light conditions, ambient temperature, calibration etc. Figures quoted are subject to change.
