VisionCommandGroup
Bases: ModuleCommandGroupBase
This command group contains functions for working with SENTIO's vision module. You are not meant to instantiate this class directly. Access it via the vision attribute of the SentioProber class.

|
The alignment threshold. |
0.05

A tuple with the x, y and theta offset in micrometer. |
align_wafer(mode)
Perform a wafer alignment.
Parameters:
| Name | Type | Description | Default |
|---|---|---|---|
mode |
AutoAlignCmd
|
The alignment procedure to use. |
required |
Returns:
| Type | Description |
|---|---|
Response
|
A Response object. |
auto_focus(af_cmd=AutoFocusCmd.Focus)
Perform an auto focus operation.
Parameters:
| Name | Type | Description | Default |
|---|---|---|---|

AutoFocusCmd
|
The auto focus command to execute. |
Focus
|
Returns:
| Type | Description |
|---|---|

|
coords |
DetectionCoordindates
|
The coordinates to use for the returned detection results. |
Roi
|
Returns:
| Type | Description |
|---|---|
list
|
A list of detected tips. Each detection result is a tuply of 6 values: x, y, width, height, score, class_id. |
enable_follow_mode(stat)
Enable or disable the scope follow mode.
If scope follow mode is active the scope will move in sync with the chuck. This is useful for keeping the image in focus while moving the chuck.
This function wraps the "vis:enable_follow_mode" remote command.
Parameters:
| Name | Type | Description | Default |
|---|---|---|---|
stat |
bool
|
A flag indicating whether to enable or disable the follow mode. |
required |
Returns:
| Type | Description |
|---|---|
Response
|
A Response object. |
find_home()
Find home position.
This function uses a pre-trained pattern to fully automatically find the home position.
Returns:
| Type | Description |
|---|---|
Response
|
A Response object. |
find_pattern(name, threshold=70, pattern_index=0, reference=FindPatternReference.CenterOfRoi)
Find a trained pattern in the camera image.
Parameters:
| Name | Type | Description | Default |
|---|---|---|---|
name |
str
|
The name of the pattern to find. |
required |
threshold |
float
|
The detection threshold. The higher the threshold, the more certain the detection must be. |
70
|
pattern_index |
int
|
The index of the pattern to find. In SENTIO each pattern may have up to 5 alternate patterns. This is the index of the alternate pattern. |
0
|
reference |
FindPatternReference
|
The reference point to use for the pattern detection. |
CenterOfRoi
|
has_camera(camera)
Check wether a given camera is present in the system.
This function wraps the "vis:has_camera" remote command.
Parameters:
| Name | Type | Description | Default |
|---|---|---|---|
camera |
CameraMountPoint
|
The camera mount point to check. |
required |
Returns:
| Type | Description |
|---|---|
bool
|
True if the camera is present, False otherwise. |
match_tips(ptpa_type)
For internal use only! This function is subject to change without any prior warning. MPI will not maintain backwards compatibility or provide support.
remove_probetip_marker()
Remove probetip marker from the camera display.
Returns:
| Type | Description |
|---|---|
Response
|
A Response object. |
snap_image(file, what=SnapshotType.CameraRaw, where=SnapshotLocation.Prober)
Save a snapshot of the current camera image to a file.
