Sebastian Günther, Host Systems Competence Center Lead at Allied Vision Technologies, presents the "Accessing Advanced Image Processing Feature Sets with Alvium Cameras Using a V4L2/GenICam Hybrid Driver" tutorial at the May 2019 Embedded Vision Summit.
Camera device drivers are a critical component for all embedded vision systems, providing an essential interface between the camera and the application software. In this talk, Günther begins by examining the key challenges associated with camera drivers for embedded vision systems. He then introduces two approaches to camera drivers: one based on V4L2 (a popular Linux API), and one based on GenICam (a formal standard created for the industrial machine vision space).
Günther examines the pros and cons of these two approaches, and presents a hybrid solution that combines support for both V4L2 and GenICam in a single driver. Such a driver is included as part of the software stack provided with Allied Vision’s Alvium embedded vision cameras. Günther introduces these Alvium cameras and illustrates how the hybrid driver can be used to enable developers to utilize the best capabilities of both V4L2 and GeniCam APIs, while minimizing integration effort.
