Operating Mode#

The Operating Mode feature determines the working range of the blaze-101 camera. You can choose between Short Range and Long Range.

The operating principle of the blaze-101 camera is based on using two exposures with different frequencies and combining the data from both exposures. The result is highly accurate depth data. This approach ensures that interferences from objects outside of the camera's working range are minimized. The other advantage is that working ranges of up to 10 m are possible. The downside is that this introduces a certain amount of motion blur.

Using the Feature#

By selecting an operating mode, the values of the WorkingRangeMin and WorkingRangeMax parameters change accordingly. These parameters are read-only. To adjust the working range, use the DepthMin and DepthMax parameters.

Info

Changing the operating mode also affects the exposure time. When changing to Long Range, the exposure time is set to the maximum value (1 ms). When changing to Short Range, the exposure time is set to the minimum value (250 µs). This is done in order to avoid overexposure in Short Range or underexposure in Long Range. Using the [Exposure Time] parameter, you can adjust the exposure time as desired.

Selecting an Operating Mode#

  1. Set the OperatingMode parameter to one of the following values:

    • ShortRange: Enables the Short Range operating mode.
    • LongRange: Enables the Long Range operating mode.

Available Operating Modes#

Short Range Long Range
Range 0.3–1.5 m 0.3–10 m
Accuracy ±5 mm (0.5–5.5 m) ±5 mm (0.5–5.5 m)
Temporal Noise <2 mm (up to 1.5 m) <5 mm (up to 5.5 m)

Increasing the Frame Rate#

In normal operating mode, the blaze-101 camera achieves a frame rate of 20 fps. This frame rate can be increased by enabling the Fast Mode feature. However, there is a trade-off between the accuracy of the depth data and the speed, i.e., frame rate. The general recommendation is to leave Fast Mode disabled unless you require a higher frame rate or if you want to reduce motion artifacts.
