Processing a video from a depth sensor
From iPiSoft Wiki
- Run iPi Studio
- Press Ctrl+O or push “Open” button on toolbar
- Choose recorded avi file
- In the “Select Video Layout” dialog select the following values:
- Depth video from MS Kinect Camera
- Number of cameras: 1
- Resolution: 640x480
- After opwning the video iPiStudio will automatically calculate background and ground plane. Please do not interrupt this calculation.
- Make sure that ground plane is detected correctly:
- Push right mouse button and drag to rotate 3d scene
- Review 3D scene
- Make sure that the virtual ground plane (marked by squared grid) matches the ground points as detected by depth sensor.
- Note that you can always get back to the camera point of view by pressing 1 key on your keyboard or pushing “Camera 1” toolbar button
- Save the project by pressing Ctrl+S or pushing the “Save” toolbar button.
- Position timeline slider to the frame where actor is in T-pose.
- Adjust actor height using appropriate slider on “Actor” tab.
- Select the “Move” tool on toolbar.
- Move actor model to match actor silhouette on depth video. You do not need to be very accurate. Note that actor model can look smaller due to its position along axis of view.
- Switch to “Tracking” tab and push “Refit pose” button.
- As a result model should be matched with actor image from video. If it does not happen then delete result using item “Edit” -> “Delete pose” from main menu and repeat above actions.
- Use sliders on “Actor” tab to morph arms/torso/legs of the model to better correspond to the actor body shape.
- Set the beginning of Region-of-Interest (ROI) to the current frame with T-pose by pressing I key on keyboard or by double-clicking on the left edge of ROI bar under timeline.
- Switch to “Tracking” tab, check “Enable foot tracking” and “Enable shoulders tracking” checkboxes.
- Push “Track Forward” button to start tracking.
- Wait for iPiStudio to process the video.
