How to acquire depth information (DPQ) with compatible Edge Models

Depth Information Guide with compatible Edge models

DinoCapture 2.0 and selected Dino-Lite models offer an improved and more accurate functionality for the acquisition of depth information. Now, users can acquire depth information from the focus shift between two focal planes during live imaging.

This functionality applies to Dino-Lite Edge Plus and Dino-Lite Edge 3.0 AM73915MZT (R10) and AM73915MZTL (R10A) with DinoCapture 2.0 ver. 1.5.40 or newer version installed. Click here to download the latest version. Contact us for capability information.
Step Reference
1 Adjust the focus to a plane of interest.
This position will be considered the reference plane as 0.
   
2 To acquire depth information, readjust the focus by:

Middle-click (mousewheel click) on a point of interest to autofocus, if necessary, scroll the mouse wheel to re-adjust the focus.

or

Press the “Ctrl” key and scroll the mouse wheel to change focus manually. The depth information is shown as the focus shift.
or "Ctrl" +

This cursor indicates that refocus mode is active and that the focus can be readjusted. A positive focus shift refers to a plane below the reference plane.
   
3 To exit Refocus mode
Left-click anywhere on the preview window or press the “ESC” key.

Depth Acquisition maximum depth range and accuracy

When performing depth acquisitions, its maximum depth range and tolerance are determined by the magnification being used. This section shows the variations in maximum depths and tolerance at different magnifications in AM4917 models.


Maximum Depth Range

The maximum measurable depths that the device can perform is referred to as maximum depth range. Usually, the higher the magnification, the lower the maximum depth range, and vice versa.


Tolerance

The tolerance is the allowable variance in depth acquisitions. The higher the magnification, the lower the tolerance, and vice versa.
