Dark Mode vs Marker Mode - Miraco

Hi! I have the Miraco Pro and I’ve been practicing for some time.

I often scan dark objects and have had decent success with the common techniques (scan spray, manually setting the exposure setting to the max, etc)

I’m seeing inconsistent behavior when comparing feature scanning in “Dark Mode” vs Marker scanning.

The dark mode feature scanning by far works the best for dark objects and I’m quite pleased with its results. But if I switch to marker mode to scan featureless objects the level of black I can pickup seems to be far less. Significantly so, even after setting exposure to max.

(I want to clarify that when I was comparing the two modes I was scanning the exact same object, same distance, same environmental lighting, and the object had enough features to be feature scanned)

This means I’m fairly limited on options when I’m scanning featureless objects that I can’t spray with scan spray (sensitive objects).

Why does marker mode have a lesser ability to scan dark objects than feature mode?

I don’t understand what would cause this from a software perspective as the Miraco should be able to apply the same parameters as dark mode while doing a marker scan.

Hi @MatthewK1

Dark mode has nothing to do with Marker mode

Marker mode uses markers to replace object features , so you are able to scan any object regardless of its features .

Dark mode only increase exposure what allows dark materials to be captured better , yet the object needs features to be able to be tracked.
The exposure it increased internally on top of the manual settings

Laser mode do have additional brightness for the lasers and exposure that why it allows to scan darker objects
Laser mode do not use feature scanning due to its very small individual frames.

Completely 2 different scanning technology here.
Impossible to apply the same rules as feature scanning have only one setting for sensors .
The power limitations of infrared or blue light is limited due to consumer safety and other factors that don’t allows to increase it’s power.
