Update Scene Objects

You are viewing an old version of the documentation. You can switch to the documentation of the latest version by clicking the top-right corner of the page.

Function

Update the pose and dimensions of the specified scene object via the vision service or parameter settings.

Usage Scenario

When running a Mech-Viz project, the position and dimensions of the scene object should be adjusted in order to avoid collisions in different situations.

Parameter Description

Update Info Source

This parameter specifies the information source to update the scene object’s pose and dimensions. The two supported information sources are Config Value and Vision Service.

Config Value

+: Add a new scene object.

-: Delete the selected scene object.

You can add or delete a scene object according to the actual requirement. The pose and dimensions of the scene object at the top of the Scene Object list will be updated first. For each item in the Scene Object list, you can select the scene object in the corresponding drop-down list and then specify the Target Pose and Target Size. The format of target pose should be XYZ (m) plus quaternions and the target size is the dimensions in X, Y, and Z-directions in meters.

For example, a target pose can be 1.00, 0.00, 0.00, 1.00, 0.00, 0.00, 0.00, a target size of a cuboid can be 0.40, 0.40, 1.00 (length, width, height), and a target size of a vertical cylinder can be 0.50, 1.00, 0.00 (radius, height, 0).

Vision Service

Vision Name

Select the Mech-Vision project that provides the vision service. The Mech-Vision project must be a registered one.

Once you selected a Mech-Vision project, please follow the steps below to configure the Procedure Out Step in the Mech-Vision project.

Go to the Step Parameters panel, and set the Port Type to Custom.
Click Set data type output to external communication, and the Procedure Out Setting Assistant window will pop up.
Click Insert to create 3 customized keys.
Double-click the customized keys to rename them to sceneObjectNames, sceneObjectSizes, and sceneObjectPoses.
Click OK to save the changes.
Connect the input port of Procedure Out with corresponding output ports respectively.

Customized Keys	Description
sceneObjectNames	The name should be consistent with that of the scene object in Mech-Viz.
sceneObjectSizes	Object dimensions in meters, (length, width, height) for cuboids and (radius, height, 0) for cylinders.
sceneObjectPoses	XYZ (m) plus quaternions.

Customized Keys

Description

sceneObjectNames

The name should be consistent with that of the scene object in Mech-Viz.

sceneObjectSizes

Object dimensions in meters, (length, width, height) for cuboids and (radius, height, 0) for cylinders.

sceneObjectPoses

XYZ (m) plus quaternions.

Example

In a scenario where a sensor door is used, this Step is used to update the model of the door, thus collisions in different processes can be avoided. Config Value is used to update the scene object in this example.
