ACE Sight Sequence Description The ACE Sight Sequence is an object in the ACE Workspace Explorer. The Sequence object shows the list of tools that will be executed as part of the sequence, the order in which they will be executed, and the Index associated with each one. The Index is the execution order of each tool. A sequence maps a V+ sequence number to the “top-level” vision tool. "Top-level" means the vision tool with the highest number in the sequence, which will be the last tool executed. This enables you to access an ACE Sight sequence with the sequence_id parameter from a V+ program instruction or function. Note that the sequence cannot be modified from the Sequence Display window.
It just shows the order in which the tools will be executed, based on the parent tool specified in each tool. The actual order of a sequence is determined when you specify the Related To parameter for each of the tools to be included in the sequence. When you add a Sequence object to the workspace, the Vision Tool parameter determines the Top-Level tool, and all the tools you spe- cified as the Related To parameter in the chain under that will automatically show up as mem- bers of the sequence, in the order you set up. In a sequence, you specify a robot-to-camera calibration (Default Calibration). The calibration is applied to any result accessed by a VLOCATION transformation function.
NOTE : V+ can access the results of intermediate (not only top-level) tools when a sequence is executed, because each tool has an index that can be accessed through V+. The Default Calibration is applied to all results, even if they are not the top-level tool.
