Live Reconstruction


Multiple marker rays contributing to the reconstruction of a marker.

Reconstruction tab contains a list of parameters for the real-time Point Cloud reconstruction engine.

Reconstruction in motion capture is a process of deriving 3D points from 2D coordinate information obtained from captured images, and the Point Cloud is the core engine that runs the reconstruction process. The reconstruction settings in the Application Settings modifies the engine's parameters for real-time reconstructions. These settings can be modified to optimize the quality of reconstructions in Live mode depending on the conditions of the capture and what you're trying to achieve. Use the 2D Mode to live-monitor the reconstruction outcomes from the configured settings.

Calibration Pane Options

Calibration display options.
Lens Distortion Visuals.

This section covers through the display options for the calibration features. In previous releases, these options existed in the Calibration pane.

Panel Output

Default: Standard. Decides whether the calibration process is displayed in a list format or a grid format. Grid format allows more camera progresses to be seen in the pane.

Status Ring

Default: Visualize. Enables the Status Indicator Ring to glow during calibration in order to display the wanding process.

Solver Visualizations

Default: Show. This toggles the display of wand samples and point cloud calibration visuals in the 2D and 3D view. If you're running on a lower end machine or graphics card with a large system, it is best to turn this feature off. The visual display will in fact eat up some computing power you may want reserved for getting quicker calibration results.

Lens Distortion

Default: Show. Use this to toggle the display of the lens distortion solution results in the 2D view. The lens distortion will be represented by a square grid that maps the distortion.

Cameras

Default: Show. This toggles the display of the cameras during the solve.

Wanding Projection

Default: Show. This toggles the display of wand samples projected in the 3D view. Turn this off if you're calibrating a very large system.

Projection Error

Default: Show. This toggles the display of error, reported as a color in the projected wand samples and markers. The wand samples will have a color between blue (good sample) and red (poor sample). Make sure the samples you collect are mostly good samples. As will all visual feedback, it may be a good idea to turn this off if you're calibrating a larger system.

Residual Error

Default: 6 mm. Set the tolerance for the reported error in the projected marker sample during calibration.

Wand Error

Default: 8 mm. This sets the tolerance for the reported error in the projected wand sample.

Sample Spacing

Default: 1. Use this to increase the spacing between displayed samples that are projected in the 3D view. Increasing this will skip more samples but will make the visual wand projections easier to see.

Skeletons


Skeleton Display Properties

A list of the default Skeleton display properties for newly created skeletons is listed under the Skeletons tab. These properties are applied to only skeleton assets that are newly created after the properties have been modified. For descriptions of the skeleton properties, please read through the Properties: Skeleton page.

Info2.png

Note that this is the default creation properties. Asset-specific skeleton properties are modified directly from the Properties pane.

Advanced Properties

Straight Arms

Creates the skeleton with arms straight even when arm markers are not straight.

Straight Legs

Creates the skeleton with straight knee joints even when leg markers are not straight.

Feet On Floor

Creates the skeleton with feet planted on the ground level.

Height Marker

Force the solver so that the height of the created skeleton aligns with the top head marker.

Rigid Bodies


A list of the default rigid body creation properties is listed under the Rigid Bodies tab. Thes properties are applied to only rigid bodies that are newly created after the properties have been modified. For descriptions of the rigid body properties, please read through the Properties: Rigid Body page.

Info2.png

Note that this is the default creation properties. Asset specific rigid body properties are modified directly from the Properties pane.

Cameras


This section of the application settings is used for configuring the properties for all of the cameras in the tracking group. The settings include display options, masking properties, but most importantly, the 2D Filter settings for the camera system which basically determines which reflections are considered as marker reflections from the camera view.

Filters (2D Object Filter)

AppSet Filter.png

When a frame of image is captured by a camera, the 2D Object Filter is applied. By judging on sizes and shapes of the detected reflections, this filter determines which of them can be accepted as marker reflections. Parameters for the 2D Object filter are configured in the Devices pane under the Filters section.

Info2.png

For Motive 2.0 and above. The 2D Object filter settings in the Reconstruction Settings pane have been moved over to the Devices pane.

Filter Type

Default: Size and Roundness
Toggles 2D object (Size and Roundness) filtering on or off.
This filter is very useful for filtering out extraneous reflections according to their characteristics (size and roundness) rather than blocking pixels using the masking tool or the Block Visible feature. Turn off this setting only when you want to use every 2D pixels above the brightness threshold from camera views. When there are extraneous or flickering reflections in the view, turn on the filter to specify and consider reflections only from markers. There are multiple filtering parameters to distinguish the marker reflections. Given that there are assumed marker characteristics, filtering parameters can be set. The size parameters can be defined to filter out extra-small or extra-large reflections that are most likely from extraneous sources other than markers. Non-circular reflections can be ignored assuming that all reflective markers have circular shapes. Note that even when applying the size and roundness filter, you should always Block Visible when you calibrate.
The size filter applied with a maximum size limit of 200 pixels. Any reflections bigger than 200 pixel-size is omitted from the Point Cloud reconstruction calculation.

Min Thresholded Pixels (pixels)

Default: 4 pixels
The minimum pixel size of a 2D object, a collection of pixels grouped together, for it to be included in the Point Cloud reconstruction. All pixels must first meet the brightness threshold defined in the Cameras pane in order to be grouped as a 2D object. This can be used to filter out small reflections that are flickering in the view. The default value for the minimum pixel size is 4, which means that more than 4 pixels need a group of pixels needs to be greater than 4 for a ray to be generated.

Max Thresholded Pixels (pixels)

Default: 2000 pixels
The maximum size of a 2D object, in pixels, in order for it to be included in point cloud reconstruction. Default is 2000 pixels which basically means that all of detected large reflections smaller than 2000 pixel-size will be included as a 2D object. Use this to filter out larger markers in a variable marker capture. For instance, if you have 4 mm markers on an actor's face and 14 mm markers on their body, use this setting to filter out the larger markers if the need arises.
The circle filter omitting non-circular reflections from a 2D camera view.

Circularity

Default: 0.6
This setting sets the threshold of the circularity filter. Valid range is between 0 and 1; with 1 being a perfectly round reflection and 0 being flat. Using this 2D object filter, the software can identify marker reflections using the shape, specifically the roundness, of the group of thresholded pixels. Higher circularity setting will filter out all other reflections that are not circular. It is recommended to optimize this setting so that extraneous reflections are efficiently filtered out while not filtering out the marker reflections.
When using lower resolution cameras to capture smaller markers at a long distance, the marker reflection may appear to be more pixelated and non-circular. In this case, you may need to lower the circularity filter value for the reflection to be considered as a 2D object from the camera view. Also, this setting may need to be lowered when tracking non-spherical markers in order to avoid filtering the reflections.

Intrusion Band

Default: 0.5 (Pixels)
The intrusion band feature allows cameras to recognize reflections that are about to be merged and filter them out before it happens. This filter occurs before the circularity filter, and these reflections are rejected before the thresholded pixels merge. This is useful for improving the accuracy of the tracking, because bright pixels from close by reflections may slightly shift the centroid locations. The intrusion band value is added to the calculated radius of detected markers to establish a boundary, and any extraneous reflections intruding the boundary is considered as the intrusion and gets omitted. When an intrusion happens, both intruding reflection and detected marker reflection will be filtered out.

Garyscale Floor

Default: 48
The grayscale floor setting further darkens pixels with lower brightness intensity values.

Object Margin

Default: 2 (Pixels)
The object margin adds an additional margin on top of the intrusion band for filtering out merged reflections. Lowering this value will better detect close-by reflections, but may decrease the accuracy of the centroid positions as a tradeoff.

Display Options

AppSet CameraDisplay 21.png

Name

Sets the name for the selected camera group.

Camera Color

Sets the color for camera group members as they appear in the 3D viewport. Color values are input as standard RGB triplets.

Visible Cameras

Selects whether cameras in the group are displayed in the viewport.

Show All Color Camera

By default, only the Prime Color cameras that are equipped with the IR filter switcher are shown in the 3D viewport and Prime Color cameras without filter switcher are hidden. When this setting is set to true, all of the Prime Color cameras will show up in the 3D viewport.

Show Capture Volume

Selects whether the capture volume (defined as capable of tracking a single marker) is displayed in the viewport. Enabling this will allow the volume to be displayed as a wire cage around the ground plane where multiple cameras fields of view intersect. Valid options are True, False (default).

Camera Overlap

Sets the minimum camera overlap necessary for a region to be visualized as part of the capture volume. Higher numbers represent more camera coverage, but they will tend to reduce the size of the visualized capture volume. Valid range is 1 to 25 (default 3).

Volume Resolution

Sets the resolution of the capture volume visualization. A higher number represents a more detailed visualization. Valid range is 1 to 120 (default 50).

FOV Intensity

Sets the opacity of the FOV visualization. A higher value represents a more opaque volume visualization. Valid range is 1 to 100 (default 50).

Opacity

Sets the opacity of the volume visualization. A value of 1 is transparent and 100 is opaque. Valid range is 1 to 100 (default 100).

Advanced

AppSet CameraAdvanced.png

Synchronization Control

Determines how late camera frames are dealt with. Timely Delivery will drop late frames, which is ideal for real-time applications where data completeness is secondary to timeliness. Complete Delivery will hold up processing of frames when a frame is late. Automatic, which is the default and recommended setting, runs in Timely Delivery mode until it gets a non-trivial percentage of late frames, at which point it will automatically switch to Complete Delivery.

Shutter Offset

Delays the shutter timing of selected tracking camera group for N microseconds.

Mask Regions

Mask Width (pixels)

Sets the extra pixel coverage (width) for masking visible markers when the mask visible function is used. A larger number will block a wider grouping of pixels simultaneously. Valid range is determined by the resolution of the cameras.

Mask Height (pixels)

Sets the extra pixel coverage (height) for masking visible markers when the mask visible function is used. A larger number will block a wider grouping of pixels simultaneously. Valid range is determined by the resolution of the cameras.
