Easy to use Jupyter notebook viewer connecting Basler Pylon images grabbing with OpenCV image processing. Allows to specify interactive Jupyter widgets to manipulate Basler camera features values, grab camera image and at once get an OpenCV window on which raw camera output is displayed or you can specify an image processing function, which takes on the input raw camera output image and display your own output.

AcquisitionFrameRateAbs fails #2

Closed Resonanz closed 5 years ago

Resonanz commented 5 years ago

The features dict works if I replace GainRaw with Gain (as noted elsewhere), however we are crashing out at 1AcquisitionFrameRateAbs

Hard to believe I have spent a couple of hours trying to make this work only to find that "AcquisitionFrameRateAbs" needed changing to "AcquisitionFrameRate". There is zero documentation for this AFAICT, and it was a guess following Basler's similar dropping of "Raw" from "GainRaw". Sigh.

From the new version you will get a much nicer exception when you use the wrong name of a feature. Closing this
