Creative BlasterX Senz3D

For the previous camera model, the Creative Senz3D module provides a module to specifically communicate with the camera. In the later model, BlasterX, this module is NO longer required. Instead you should install the DirectShow drivers provided by Creative which will install drivers that will make the camera appear like a regular camera. Once this is done, you can press the Camera button on the main RoboRealm GUI and select a particular image using the Options Button->Video Tab->Camera Source->SR300 Depth. To capture a particular image select the Video Format button and one of the Color Space / Compressions. The following indicates what these modes mean:
  • YUY2 - Produces a single green image. This mode appears to be a test function that we believe is provided to allow for a compression mode that is well recognized. There is no functional propose for this mode.
  • INVZ - Produces just the Depth/Distance map the camera is sampling. Brighter / higher intensity values are closer.
  • INZI - Provides both the IR image and Depth map. The Driver combines these two images into a single image which RoboRealm is breaking into two individual images. In order to show both using the same image dimensions, RoboRealm will reduce the image sizes to 1/2 the actual size just for preview. At the same time two Marker images are created which are from the full resolution images called CAMERA_IR and CAMERA_DEPTH. These marked images can then be displayed using the Marker module or referenced by other modules like the Display Image, Math, etc. modules.
  • INZC - Provides both the IR image and a confidence image. The Driver combines these two images into a single image which RoboRealm is breaking into two individual images. In order to show both using the same image dimensions, RoboRealm will reduce the image sizes to 1/2 the actual size just for preview. At the same time two Marker images are created which are from the full resolution images called CAMERA_CONFIDENCE and CAMERA_DEPTH. These marked images can then be displayed using the Marker module or referenced by other modules like the Display Image, Math, etc. modules.
  • INVI - Produces just the IR image that the device uses to detect depth (time of flight). If you point the camera outside in full sunlight you will understand why the device does not work in sunlight. The sun produces a lot of IR light that will confuse the camera.
  • PAIR - Appears to switch between the IR Image and another unknown image.

As all formats provide 12 bit data precision, RoboRealm will use the Options Button->Application-> Higher Bit Images to convert that value into an 8 bit value. You can access this interface and change how the precision is mapped to utilize which part of the 12 bit range is ideal for your application. The default 'High' will use the upper 8 bits of the provided value. For the IR images, 'Normalize' helps to bring out the details.

This page describes the formats for the Depth Camera Source. One can also select the RGB camera source to gain access to the regular RGB source.
