Troubleshooting

The application will not launch / crashes / crashes my computer.

  • Maybe your system doesn't support the toolkit. You'll need a computer with accelerated graphics no more than 4 or 5 years old.
  • Make sure you have not moved the data/ folder in relationship to the DepthKitCapture or DepthKitVisualize applications
  • If you are using the Asus Xtion Pro, make sure you've installed the Sensecast drivers.)
  • If you are still experiencing problems... search the DephtKit Forum.

My depth camera feed is not showing up in the Calibrate Lenses tab.

  • Try disconnecting and reconnecting your depth camera, then restarting the application.
  • If you are using Kinect, make sure that you are running the appropriate Kinect capture application (1414 vs 1473), based on the model number on the bottom of the device
  • Occasionally fully restarting the computer has helped with sensors that fail to pick up.

My depth camera's field of view / principal point don't match the figures given in the video.

  • If they are only slightly different, don't worry!
  • Try the process again from scratch by disconnecting devices and relaunching the application.
  • Make sure there is information in the scene that falls within the range visible to the sensor (~3'-12').
  • Check that there is variation in the scene; information in the foreground, middle and background.

I'm getting high error numbers on the calibrate lenses page.

  • High error may occur when the checkerboard is too close or too far away.
  • Make sure there is no glare on the checkerboard from lights. Even one hot spot from a nearby light could throw off the reading.
  • Make sure that the exposure is set properly on the camera - if the whites of the checkerboards are too bright sometimes you need to shoot it again at a slightly darker exposure.
  • Make sure you refocused on the checkerboard at every stage and that your aperture is no too low, making the depth of field shallow.

My correspondences are not detecting or way off.

  • Confirm that you have a low error on the first stage.
  • Make sure that your set up is totally stable when capturing the correspondence images. A wobbling checkerboard or camera tripod will throw things off.
  • Often this will happen if there is not enough ambient IR light, get closer to a window
  • Conversely if there is too much or uneven lighting it'll also blow out your checkerboard
  • Try different depths from the camera, being wary moving it too close or too far.

My recordings are dropping frames.

  • Close any other apps.
  • Make sure you are plugged into wall power
  • If writing to an external hard drive make sure it's USB 3.0 or FireWire 800.

The application crashes when I try to load movie files from the HD camera.

  • Makesure your video files are compatible with the toolkit, H.264 or ProRes MOV's.
  • Make sure you have the latest version of Quicktime installed
  • Make sure you are running the application from a location where you have write access

My texture alignment is way off.

  • Try using the X & Y shift and Scale in the Texture Alignment tab to accommodate for slight inaccuracies.
  • You may want to recalibrate, which is fine to do after you've shot as long as the relationship with the camera is still fixed.

My time alignment/synch is way off.

  • Delete any markers on the 3rd "Alignment" track on the timeline to start over.
  • Look for a very decisive temporal moment to align to, meaning that there is a specific fast movement which allows for precisely selecting a depth and video frame from close times. Because the cameras have different frame rates and clocks, the alignment will never be perfect but should not drift over time.
