Image Components#

The Basler blaze-101 camera generates three different image components. Depending on the image component, different pixel formats are available.


  • Range Map
    This is the depth image. It represents the distance between the target and the camera per pixel. Strictly speaking, it is the time that passes between sending out a light pulse and the light pulse returning to the sensor.
  • Intensity Image
    The intensity image shows the brightness of the reflected light pulses as 16-bit integer values per pixel. Technically speaking, this is an amplitude image as it only contains the near-infrared portion of the light while any ambient light is filtered out.
    Because the wavelength of the light sent out by the camera has an influence on this, the intensity image may differ from the human perception of the target scene.
    The intensity image is useful for checking the image for over-/undersaturated pixels. To avoid these, try changing the exposure time or the camera position and check whether the image improves.
  • Confidence Map
    The confidence map is a visual representation of how reliable the depth image data is. If no reliable depth data is available, a pixel is set to zero in the confidence map. If the depth data is reliable, the pixel is set to 255 (for 8-bit pixel formats) or to 65535 (for 16-bit pixel formats).
    Using the ConfidenceThreshold parameter, you can control which depth data is considered reliable.

Selecting an Image Component#

You can choose which image component you want the camera to transmit by enabling the respective component using the ComponentSelector parameter.

To select an image component:

  1. Set the ComponentSelector parameter to the desired component:
  2. Intensity: The intensity image will be selected.
  3. Range: The range map will be selected.
  4. Confidence: The confidence map will be selected.
  5. Set the ComponentEnable parameter to true.
  6. Set the PixelFormat parameter to the desired pixel format for the component.
  7. Repeat for other components if required.
