Image settings

Single parts of the simulated image. The console's IMAGE key switches them all: REALISTIC = everything on, SIMPLE = no shadows and no depth attenuation. Changing one here shows CUSTOM.

Hand Setup

Where you sit relative to the camera. Set once, then leave alone. These have no effect in PROBE or QR mode.

Needle

The ArUco needle (marker 9), printed or shown on a phone. Turn it on with the NEEDLE button or the N key. Print needle template

Marker size (black square, mm)

40 mm

Measure the black square with a ruler and set it here. This is the needle's only scale: too small and everything reads too close. Bigger is better — aim to fill the phone's width.

Needle length (mm)

70 mm

Visible slab (± mm around the image plane)

±3 mm

The needle and its path are drawn only inside this slab — as a real scan shows only what crosses the beam. Thinner is sharper and less forgiving.

Trajectory length (mm)

200 mm

Line thickness (px)

3.5

Reach per hand movement

auto

How far the needle travels while you position it. With the paper probe and Pivot on skin the needle moves exactly as far as the probe, so the two stay together (this slider is used only otherwise). Insertion depth is always 1:1 and is not affected.

Camera Calibration

Using default intrinsics (60° FOV estimate)

Print a 7×5 chessboard (25mm squares), hold it at different angles, capture 5+ frames, then Compute. Print chessboard

Volume Transform

Probe Debug

In PROBE input (the default), show the probe to the camera. Green outlines are faces the tracker is using; dark red are seen but ignored (edge-on, or disagreeing with the others). The beam leaves from the bottom lid (marker 10).
