Software
Drag and Bot robot software integrates Basler drivers Basler’s Pylon camera software for Linux has been integrated into graphical robot programming software Drag and Bot. Te functionality means it is now possible to
operate Basler 2D cameras in robotic applications through Drag and Bot’s graphical user interface. Drag and Bot is a spin-off from the Fraunhofer
Institute for Manufacturing Engineering and Automation (IPA) in Stuttgart. Te company’s vision is to make programming industrial robots as easy as using a smartphone. Drag and Bot software is independent of robot
manufacturers, and designed to simplify setting up, programming and operation of industrial robots. Users are able to drag and drop function blocks in the GUI, such as a robot movement, closing the gripper, or locating a workpiece. Te company also offers services around
planning and development of robotic solutions. Te work between Basler and Drag and Bot has
also resulted in an improved driver for Basler 2D cameras for the open source framework ROS. An enhanced version of the Pylon ROS driver
is available for download via github and means Basler 2D cameras can be integrated into ROS projects. ROS is an open source framework for building
robot systems. It was originally developed for service robots, but is increasingly being used for solutions in industrial robotics. Te ROS driver supports both USB and GigE 2D cameras, and allows the use of a variety of camera functions and parameters.

Common Vision Blox 2019 Common Vision Blox 2019, from Stemmer Imaging, introduces new APIs: CVB Image Manager and CameraSuite 2019 feature three new object-oriented APIs, supporting C++, .Net and Python. Te CVB Foundation Package
2019 now benefits from a communication framework for OPC UA and polarisation functionality, as well as improvements to speed and stability of 3D calibration in Metric. Te OPC UA framework allows OPC UA server and client functionality. Te software’s new polarisation
VisualApplets 3.2 Silicon Software has released version 3.2 of its VisualApplets graphical development environment. Te new version has a scalable operator for Jpeg compression of greyscale and colour images, and has further developed the automation of the software by a Tcl console. Te Jpeg operator is freely scalable to
any image input data rate, which is only limited by available FPGA resources. Tis makes it a future-proof solution for the latest FPGA technologies and VisualApplets-compatible hardware, such as frame grabbers, cameras and vision sensors. Limitations by the bandwidths of interfaces such as Camera Link HS and CoaXPress and by the DMA transfer bandwidth can be compensated by Jpeg compression. Tis allows current high-performance camera sensors to be used at full bandwidth. Additional image pre- and post-processing at Jpeg compression can be integrated into the VisualApplets design. Te operator compresses 8-bit greyscale
images and 24-bit RGB colour images with variable image compression rates in real-time on the FPGA. It has flexible setting options, such as those for image quality, compression rate and header information. Te Jpeg operator can be used effectively wherever continuously high image data volumes are created, for example, by long image sequences or high- performance camera interfaces. Te Jpeg operator is available as a separate
license within the extension VisualApplets libraries, and runs on the MicroEnable 5 frame
grabber series. It is also possible to continue using the previous version of the operator. Te Tcl console with built-in Tcl interpreter
simplifies script-based work with VisualApplet designs. More than 80 commands are available for direct input or creation of Tcl scripts. Te command set allows the creation, manipulation and simulation of designs. For example, complex processes such as the simulation of thousands of images with different parameter settings can be performed automatically via script. In addition, external image processing
software can be connected to transfer design parameters or images. Script Collection makes it possible to build libraries of self-defined Tcl scripts, parameterise them and execute them from the user interface. Te Tcl console is part of the extension VisualApplets Expert. Te new version of the VisualApplets
Embedder extension supports vision platforms using Ultrascale or Ultrascale+ FPGAs.

toolbox allows easy access to the data from polarisation sensors from Teledyne Dalsa and Sony. De-mosaicing, minimum reflection images, Stokes’ parameters, and the angle/degree of polarisation can be handled, enabling reflectivity and surface-normal calculations. CVB Spectral is a new tool for acquiring and preparing hyperspectral data from hyperspectral cameras and ENVI files, so traditional image processing tools can be used on results. A hyperspectral data cube, which can also be acquired, saved and loaded using CVB Spectral, can be

corrected for optical and lighting effects to create wavelength-correct RGB or LAB colour data. Tis gives real area colorimetry information far more accurately than with three- chip cameras. Te data cube can be sliced to produce 2D images.
Te software release also makes
it possible to develop machine learning solutions on embedded platforms. Object recognition speeds have been increased, as have video sequence recording speeds.
