Technical Specs

The rc_visard provides time-stamped disparity, error, and confidence images over the GenICam interface (see
Chunk data, Section 8.1.1). Live streams of the images are provided with reduced quality in the Web GUI (Section
4.5).
6.2.4 Parameters
The stereo matching component is called rc
_
stereomatching in the REST-API and it is represented by the Depth
Image tab in the Web GUI (Section 4.5). The user can change the stereo matching parameters there, or use the
REST-API (REST-API interface, Section 8.2) or GigE Vision (GigE Vision 2.0/GenICam image interface, Section
8.1).
