Reality Capture:

Capture 3D measureable images.


Use the integrated Laser EDM to add highly accurate measurements to 3D images, or to take stand-alone measurements.

Sketch & Document:

Create floorplans and attach measurable images to them. Useful for documenting construction progress over time.

Reality Capture

The BLK3D captures images and places precise measurements at your fingertips. Share images and measurements in multiple formats.

Watch Leica Geosystems Technical Specialist Andy Fontana capture a 3D image and take measurements in the field.


The BLK3D represents a new way to capture and document reality by combining measurement sensors, software, and on-device data processing. Its integrated stereo-camera captures images that provide a complete 3D record, with:

EDM accuracy of 1mm*

2D in-picture accuracy of +/- 3mm*

3D in-picture accuracy of +/- 6mm*

*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 assume normal to favourable conditions at close range and are subject to change.

Single-Shot or Multi-Shot?

The wider the baseline, the better the accuracy.

The BLK3D can extend the baseline by capturing two 3D stereographic images side-by-side.

When accuracy is paramount, use the integrated Laser EDM to attach precise measurements to an existing 3D image, or use it to draw a 2D or 3D floor plan from scratch.


In a single-shot 3D image, the baseline is the distance between the two camera lenses.

Single shot accuracy is adequate for estimation tasks like documenting storm damage or for 2D measurements at close range.


In a multi-shot 3D image, the baseline is extended by moving laterally and taking a second shot of the same object.

Multi-shot accuracy is recommended for tasks like construction progress documentation where 3D measurements at longer range are required.

Working with 3D Images

Capture an image and measure distance or area, including depth, on the device instantly.

Advanced snapping algorithms make it easier to pick the right pixel to measure from.

Share Your Work

Export 3D images in PDF or JPG format.

Send 3D images captured by the BLK3D back to the office where they can be opened and edited with the BLK3D Desktop Software.

You can also export JPGs or PDFs and send them from the BLK3D via WiFi.

Smart Room

In addition to measurable 3D images, the BLK3D creates highly accurate 2D and 3D floorplans.

Watch Andy use the integrated Laser EDM to create a floorplan using the BLK3D's on-board Smart Room feature.


Draw a rough outline of a room on the touchscreen, fill in values by hand or using the Laser EDM, and attach images.

Watch the sketch and document functions in action.


Add 3D images to specific locations in floorplans.
