Fixture3D

The Fixture3D function Functions are tools that are available in Spreadsheet for processing and analyzing acquisitions or other results. You can add functions to your Spreadsheet job to create tool chains and produce results for specific applications. allows you to set up fixturing coordinates that can be used by other 3D Vision Tools.

It returns a Fixture3D structure containing the configured fixture A fixture is a coordinate location on the image that keeps the tool in the place determined by the fixture. coordinates.

Inputs

The Fixture3D function has the following syntax:

Fixture3D(PointCloud A point cloud is a 3D structure that consists of the data points collected by a 3D vision system during acquisition.,Fixture3D,Show)

Parameter

Description

PointCloud

Reference to a cell containing a point cloud A point cloud is a 3D structure that consists of the data points collected by a 3D vision system during acquisition.. The default value is $A$0.

Fixture3D

Specifies the point cloud coordinate system in which the 3D fixture is defined. It is offset from the PointCloud origin in the following format with the following arguments:

{X, Y, Z, Rotation, Tilt, TiltDirection}

X	Offset on the X-axis from the PointCloud origin.
Y	Offset on the Y-axis from the PointCloud origin.
Z	Offset on the Z-axis from the PointCloud origin.
Rotation	Specifies the in-plane rotation in degrees around the PointCloud Z-axis. The value range is -180 to 180. The tool normalizes external references with values outside the allowed range to the allowed range.
Tilt	Specifies the tilt angle in degrees from the PointCloud Z-axis after rotation. The value range is 0-180. External references with values outside the allowed range result in an error.
Tilt Direction	Specifies the direction of tilt in degrees from the rotated PointCloud X-axis of the tool, around the PointCloud Z-axis of the tool. The value range is -180 to 180. The tool normalizes external references with values outside the allowed range to the allowed range.

Note: The Fixture3D parameter is only available if you set External Fixture to 0.

Note: You can use the Fixture3D parameter to set the ROI fixture.

Show

Selects the type of graphics to overlay on the image.

0 = hide all (default)	All graphics will be hidden, except when the cell containing the function is highlighted in the spreadsheet.
2 = input graphics only	The input data will be displayed at all times.

Outputs

Returns

A Fixture3D structure containing the parameters of the configured fixture coordinates, or #ERR if any parameter has been configured incorrectly.

Results

When initially inserted into a cell, the following functions are automatically inserted into the spreadsheet to create a result table.

	X	Y	Z	Rotation	Tilt	TiltDirection
❒Fixture3D	GetX(Fixture3D)	GetY(Fixture3D)	GetZ(Fixture3D)	GetRotation(Fixture3D)	GetTilt(Fixture3D)	GetTiltDirection(Fixture3D)

Vision Data Access functions

The following Structures 3D Vision Data Access functions are automatically inserted into the spreadsheet to create the result table:

Function	Description
GetRotation(Fixture3D)	Returns the rotation of the Z-axis in degrees, also known as the in-plane rotation.
GetTilt(Fixture3D)	Returns the tilt angle of the Fixture3D structure in degrees on the Z-axis.
GetTiltDirection(Fixture3D)	Returns the tilt direction angle of the specified Fixture3D structure in degrees. The angle is measured in the X-Y plane of the original reference coordinate system, and specifies the direction for the projection of the tilted Z-axis onto that plane.
GetX(Fixture3D)	Returns the X-axis coordinate of the fixture's center point.
GetY(Fixture3D)	Returns the Y-axis coordinate of the fixture's center point.
GetZ(Fixture3D)	Returns the Z-axis coordinate of the fixture's center point.
