PFTrack 是 Pixel Farm 研究开发的成象物体跟踪软件(人工智能在图象处理中研究应用)。是一种摄像机反求,使其得到真实摄像机的参数,使3D物体和实际拍摄物体完美的结合的软件，它包括一些独特的功能，如：光场流分析(Optical Flow analysis)工具, 先进的物体跟踪, 几何形体跟踪, 基于场景分析的物体建模, 自动景深(Z)提取, 等等。
FXPHD PFT303 ADVANCED PFTRACK 3D TRACKING MASOCHISM
In this advanced PFTrack course, the focus is on complex shots, long shots, and those shots that make you lose your sleep. fxphd favorite Victor Wolansky will also be focusing on the critical details and skills that can take your tracking ability to the next level and really stand out in your job.
We’ll be covering workflows for extremely distorted footage from EPIC shoots in 5K. Wolanksy will be using user survey info to solve shots which are in other ways impossible to solve. This will include extracting information from an exclusive fxphd LIDAR shoot and scan, perfectly matching cameras to the scan. Wolansky will also cover the tracking of objects in scenes. The course will also naturally cover all the beauty and complexity now possible with the nodes and trees available inPFTrack. This brings a power never-before seen in 3D tracking, with almost infinite combinations to adapt to the artist’s needs.
Wolansky started working in postproduction 20 years ago… in Argentina, about 12 years ago and discovered what was 3D tracking, and since then he was unable to stop tracking shots, even if just for fun. He discovered that was the most fundamental skill needed to master in order to do anything on any shot. “All starts by a 3D tracking right? If you don’t have a 3D tracking,” says Wolansky, “you can’t put the CG in there. right?” Postproduction took him from Argentina to Chile in 2000 and to the US in 2005 where he has worked at E3 post since then.
