cvision focus assist
distance measurement is science
What is cvision focus assist?
The cvision measurement unit uses 2 cameras to create and display a stereoscopic depth map from 250,000 real-time measurement points. Various measuring and autofocus features are made possible through the live-view touch screen interface. “Single point” allows you to measure your set on the fly. “Tracking” locks onto a subject allowing you to track it through the shot, or even select your subject before entering the frame. “Nearest” allows you to select a user defined area where the closest subject to the camera is measured and kept in focus - which is a great feature to pick perfectly sharp shots even during a run and gun shoot.
In combination with a cPRO lens control system, cvision offers advanced autofocus features but also manual control at the press of a button. cvision is the ultimate focus assist on set. But, it can also be used standalone for unmanned cameras in a broadcast environment.
