Overlay Object
Live Video Display Affected by Overlay Object
If you configure and display a large number of Overlay items, the OMI live video display
frame rate can be reduced.
MVS-8110/CVM1 and XC-55: Moving Box Overlay
Hangs OMI
The following combination of steps has been found to hang OMI 2.3.
1. Set up Image object with Format=5: "Sony XC55BB 640x480."
2. Create Overlay object with Type=4 "Box".
3. Set the Show mode to "Interactive."
4. Start live video.
5. Randomly move and resize the box.
After approximately 10-20 seconds, OMI locks up.
PMPattern Object
PMPattern Cannot Be Trained with Nonlinear
Calibration
If you train a PMPattern using a training image whose World coordinates have been
calibrated using a nonlinear grid of dots calibration, any attempt to locate that pattern
using the PMTool object will return the wrong pattern location, regardless of how the
search image is calibrated.
You can use the PMTool object with nonlinear calibration by following these steps:
1. Acquire an image of the calibration plate and perform a linear calibration.
2. Acquire the training image and train the PMPattern object.
3. Recalibrate the image from step 1 using the desired nonlinear calibration.
4. Acquire the search image and run the PMPattern tool as you would normally. The
PMTool search results are returned in the current nonlinear World coordinate
space.
