Optical Flow

Technical NI LabVIEW
1

Hello. I am attempting to use NIs optical flow (HS) VI. Unfortunately, I get an error: “IMAQ Vision: Incompatible image size.”

The code is using IMAQdx for image acquisition. I have found out that this is not the issue though, as other VIs, such as colorThreshold, work perfectly fine.

The vi is attached.

When I started working with this VI I received the same error. The solution I found is the fact that both your current and previous image must have the same dimensions for both the x and y directions.
