Join Jim Jachetta along with MC Patel and find out about the top four use cases in which real-time correction of lens distortion can transform live video into a valuable addition to your live production.
Small broadcast-quality HD cameras with wide-angle or fisheye lenses are both a practical and cost-effective solution for live sports and reality TV broadcasts, as well as a host of other applications including medical, forensics/security, concerts and other live events, covert wildlife image capture, electronic newsgathering, and more. Due to their compact size and lower cost, such cameras can be deployed with much greater flexibility than larger broadcast cameras to bring viewers new or unusual perspectives. Unfortunately, the wide field-of-view lenses typically used with such “micro-cameras” give rise to lens distortion and curvilinear perspective image artifacts resulting from camera positioning. To incorporate live video from HD micro-cameras into high-quality applications, broadcasters and production companies must be able to correct for these distortions in real-time.
Join us on 22 July and get the inside scoop on:
- Removal of Curvilinear Artifacts
- Adjustment of Rotation
- Virtual Camera Off-set
- Optimization of Zoom
Geometry plays a big role in the world in which we live. Straight lines and the shapes they create are included in much of what we see before us. Geometric optical lens distortion changes the way lines appear on the screen. This is a problem facing many modern videographers as the use of fisheye and wide-angle live HD cameras become more fluent in mainstream recording.
While wide-angle cameras provide an added level of depth which standard lenses don’t capture, it does pose some problems in terms of rectilinear projection. The lines which were once straight begin to curve and distort around the edges of the shot. This optical aberration makes it difficult for viewers to determine what they’re looking at in the moment.
For videographers with the time to correct these issues during the editing process, it’s not a problem. However, live broadcasters recording sports games, local news, research for the medical industry, or even corporate AV, are unable to rectify the distortion before the image reaches viewers. This is where VidOvation’s AlphaEye becomes an asset.
