Updates from VisionLib – Release 2.2 Available

There is a new VisionLib Version available. Release 2.2.0 is a maintenance release introducing improvements to the performance of internal image processing, several bug fixes & enhancements and updates to external dependencies to remove known vulnerabilities.

As usual, VisionLib comes with enterprise-grade model tracking, multi object-tracking, ARFoundation integration, TextureColorMode to derive a line model from texture, and so much more. 

Good debugging options, examples scenes, direct influence on the vision system, and offsite testing with recorded sessions and image sequences make development easy. Explore the update now.

What Updates Come with 2.2.0?

  • We’ve made changes to ModelTracker.cs and TrackingAnchor.cs  which enable to load additional models (model parts) for one tracking target during runtime, or to load a dedicated model, specified by an uri.
  • The DeviceInfo.Camera now has properties (supportsDepthData and supportsSmoothedDepthData)to check for the acquisition of (smoothed) depth data, working with respective (depth-capable) cameras.
  • To remove known vulnerabilities, we’ve updated external dependencies (curl, Eigen, ffmpeg, libJPEG, libPNG, libTIFF, OpenCV, OpenSSL), and removed external dependencies entirely for: imagexx, jpegxx and pngxx.
  • The table below highlights the changes. You can also compare the current list of dependencies (2.2.0) with the list of the prior SDK version (2.1.0) to check whether this might impact you.
