COMMON VISION BLOX

To stay in line with recent developments in the GenICam standard, the acquisition engine of CVB has been modified to accommodate some of the recently introduced use cases:

• Acquisition from devices that provide more than just one data stream
• Acquisition from devices that provide a structured buffer with multiple distinct parts
• Acquisition from devices that do not send a “traditional” image buffer but data like 3D point clouds or HSI cubes
• Acquisition into buffers that have been allocated by the user (as opposed to buffers that have been allocated by the driver itself)

The new 3rd Generation image acquisition interfaces, introduced in Common Vision Blox 2021, are now also available in the object oriented wrappers C++, CVB.Net and CVBpy.

Using the CVB Web Streaming Library camera images could be displayed or processed on multiple applications and multiple machines or devices absolutely independent of the operating system. Images are streamed as JPEG or RAW data over http and can be displayed or processed on any client without the need of a CVB installation on the clients.

The new MultiStream support enables cameras that stream multiple datasets such as prism-based cameras with colour and IR datasets, while MultiPart acquisition supports cameras that deliver complex data such as 3D cameras where separate and different formatted data needs to be transmitted, for example 3D point cloud, RGB surface and information about data integrity at the same time.

DNC is a CAD-based 3D-object recognition tool. It allows to locate objects described by a CAD file in point clouds. Only the geometric properties of the object are taken into account, its color and texture do not matter. This is where the name of the tool comes from: Depth No Color. It is aimed at pick and place and 3D object tracking applications

Linux support has been extended to include Ubuntu 20.04.
