Hello CD!
My team and I have created a vision code and we wanna check it. We’ll know if it works by using the Imgproc.rectangle() on the image and if the rectangle is on the retroreflective lines we’ll know if the processing worked. Problem is: Imgproc.rectangle() returns a Mat image. So we’d like to know if you can put a Mat in the SmartDashboard and if so, how do we do it?
Have you looked into WPILib’s CameraServer code (cscore)? I would try that.
