This type of mixed content display is commonly used in applications, such as aircraft refueling boom control stations and UVS Ground Station controls, where a live video feed is shown with additional data to give the operator more details on distances or other operating parameters.
Running on the Wind River VxWorks Real-Time Operating System (RTOS), this application shows how easily third-party code can be integrated in a VAPS XT application through the use of custom coded objects.
After declaring the object’s properties and events, the VAPS XT Code nGEN is used to generate a template for the new object. The developer can then insert the appropriate function calls in this template to implement the desired functionality; in this case, the code to render images from the incoming video stream. For trade show purposes, the video frames are coming from a video source stored on disk but this video would be easily replaced by a live video feed in the final product. You might recognize the output of our Vega Prime Sensors tool as the background video in the above picture.
In terms of hardware, this demo is shown on an XMC-710 embedded computing platform and SkyQuest display device, both provided courtesy of Curtiss-Wright.
Many thanks to our partners for their support with these demos and at the show!
