M8 – 170° – 2mm M8 mount, 2mm focal length, 170° horizontal field of view. These are the standard lenses on the DUO M. Focal Length: 2.0mm Aperture: F2.0 Horizontal Field of View: 170° Mount Type: M8x0.5 Back Focal Length 2.8mm External Dimensions (mm): ø10 x 7.4 (L) M8 – 170° – 2mm (IR) M8 mount, […]
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 […]
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 […]
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. […]
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 […]
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.
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.
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 […]
With the DUO M/MLX sensors; each image sensor outputs 8-bit linear image data in RAW format.
