The ZED CHOP reads positional and plane tracking from the ZED camera.
Parameters - ZED Page
active - When 'On' data is captured from the ZED camera.
camera - Selects which ZED camera to use.
cameraposition - Returns the camera position relative to the intial position of the camera. A
tz triplet of channels will be output for the position of the camera in meters. An
rz triplet will be output for the orientation.
resetcameraposition - Zeros out the current camera position, effectively makes the current postion the new origin.
planeatpoint - Enables plane at point, which returns the position of the plane corresponding the UV coordinate.
referenceframe - ⊞ - Selects the reference frame for plane position.
world- Plane position outputs are relative to the initial position of the camera.
camera- Plane position is relative to the initial position of the camera.
u - Sets the U coordinate of the point in the image to extract plane position.
v - Sets the V coordinate of the point in the image to extract plane position.
normal - Returns
nz normal channels of the plane.
center - Returns
tz position channels of the center of the plane.
extents - Returns width and height of the bounding rectangle of the plane.
Parameters - Common Page
timeslice - Turning this on forces the channels to be "Time Sliced". A Time Slice is the time between the last cook frame and the current cook frame.
scope - To determine which channels get affected, some CHOPs use a Scope string on the Common page.
Sample Rate Match
srselect - ⊞ - Handle cases where multiple input CHOPs' sample rates are different. When Resampling occurs, the curves are interpolated according to the Interpolation Method Option, or "Linear" if the Interpolate Options are not available.
- Resample At First Input's Rate
first- Use rate of first input to resample others.
- Resample At Maximum Rate
max- Resample to the highest sample rate.
- Resample At Minimum Rate
min- Resample to the lowest sample rate.
- Error If Rates Differ
err- Doesn't accept conflicting sample rates.
exportmethod - ⊞ - This will determine how to connect the CHOP channel to the parameter. Refer to the Export article for more information.
- DAT Table by Index
datindex- Uses the docked DAT table and references the channel via the index of the channel in the CHOP.
- DAT Table by Name
datname- Uses the docked DAT table and references the channel via the name of the channel in the CHOP.
- Channel Name is Path:Parameter
autoname- The channel is the full destination of where to export to, such has
autoexportroot - This path points to the root node where all of the paths that exporting by Channel Name is Path:Parameter are relative to.
exporttable - The DAT used to hold the export information when using the DAT Table Export Methods (See above).
