What is accuracy of the depth map?

In general we recommend using the DUO M/MLX sensors within 0.23-2.5m using the provided Dense3D and Calibration Applications. With this you should expect to receive around 0.1-0.3mm accuracy with epipolar lines that are aligned to within 0.05 pixels RMS error based on a stereo resolution of 320×240. The resulting depth map accuracy or the sensor […]

Can I customize the lenses/filters?

The DUO M/MLX both use standard M8 lens mounts which accept any M8 style lenses. On the DUO M base board we allow for either M8 or M12 lens mounts which gives users more options when selecting a lens. On the MLX specifically the lens you use must be able to fit through the lens […]

What is the wavelength of IR filters?

By default the MLX has a IR (infrared) bandpass filter installed. These help cut out any ambient lighting that may interfere with your vision algorithms. The filter we use range is 850nm +/- 20nm. As you can see in the chart above we only allow a small range of light to pass into the sensor. […]

What is the difference between M and MLX?

The key difference between the M and MLX is that the MLX comes with a top board with the programmable LED array and integrated motion sensor (6 Degrees of Freedom). Both the M or MLX have the same footprint of 52x24mm with the MLX having a slighting taller profile of 13mm. The DUO M is […]

What is the effective range of the DUO?

The DUO M/MLX sensors were purpose built as short range sensor. Depending on specific algorithms and lighting conditions the recommended range of the DUO sensor is 0.23-2.5 meters. This can be extended with a smaller FOV and/or external illuminators as well as using different algorithms/techniques for measuring depth/objects.

What is the programmable LED array?

The fully programmable LED Array allows users to “program” the sequences that control the timing, firing and brightness of the 3 IR LEDs. We use custom firmware code in conjunction with an LED driver to do this, not an FPGA.

External Trigger/Synchronization?

The DUO M/MLX both provide 3 pins on the PCB which allow for the following configurations: SYNC_IN – Allows to force camera exposure time with external device signal. TRIG_OUT – Allows the device to trigger external lighting or other devices. GPIO – General purpose PIN used for communication between linked devices. More documentation on this […]
