OpenPnP: Multi-Shot Bottom Vision

Align parts that are too large for the camera view, or not rectangular, and more.

OpenPnP: Nozzle Tip Changer Vision & Z Calibration, Part Height Sensing

Made a new OpenPnP Pull Request that adds Nozzle tip changer XY and Z calibration using vision and probing. Used to calibrate the nozzles and nozzle tips to be able to precisely contact probe part heights, feeder heights and placements. Also adds Auto-Focus based part height sensing for parts with …

OpenPnP: Camera light actuators and more

There is a new testing version available featuring new built-in camera light actuation (no more scripting). It can support new Profile actuators, so you can control multi-channel lights like RGB etc. A pipeline can optionally control the light actuation, so different light profiles can be used on different pipelines. In …

Camera FPS, CPU load and Lighting/Exposure

I’ve just confirmed an old suspicion of mine. Camera frames per second (fps) depend on lighting or rather on the exposure you need to set for the given lighting situation. This is at least true for the ELP FullHD camera and the new 720p 120fps global shutter camera I’m evaluating. …

OpenPnP: Advanced Camera Settling

Made a new Pull Request to OpenPnP. When the Camera needs to take a picture for Computer Vision, it needs to be stable, i.e. all machine motion, vibrations etc. must have ceased. For the machine to be fast, this should be adaptive tho the motion that the camera observes. The …

OpenPNP: New ReferencePushPullFeeder

Made a new Pull Request for the ReferencePushPullFeeder class in OpenPNP (Update: the PR is now merged into OpenPNP 2.0). This is the software side of the all 3D-printed PushPullFeeder: Generic implementation for a feeder that can feed parts by performing push and pull (and other) motions using a head-mounted …
