影视软件 跟踪类 CG资源网
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。
 
PFTrack enables computer generated effects to be matched with film or video sequences no matter what their resolution. PFTrack is also a suite of analysis technologies designed to extract both detailed camera information and pixel motion data from video and film sequences and allow this data to be fully utilized within a post-production environment.
 
The unique geometry tracking system in PFTrack allows 3D geometry to be imported into PFTrack and then matched to sequences, making this an ideal tool for head and facial replacement meaning artists can now be confident that animated CG, when rendered and composited, will exactly match the live action. Complex Geometry can be imported and used to solve cameras in addition to the use of automatic or user placed features. This is perfect for problematic shots or for tracking set extension models into footage. Using motion groups it is a simple task to extract both camera and object motion. Any or all motions can be exported along with animated geometry if required. Version 5.0 includes Geometry Tracking vertex weighting this allows you to paint the influence each vertex point has on the final tracking. A simple paint tool allows you to quickly paint onto the imported 3D geometry.
