PFTrack 是 Pixel Farm 研究開發(fā)的成象物體跟蹤軟件(人工智能在圖象處理中研究應(yīng)用)。是一種攝像機反求,使其得到真實攝像機的參數(shù),使3D物體和實際拍攝物體完美的結(jié)合的軟件，它包括一些獨特的功能，如：光場流分析(Optical Flow analysis)工具, 先進的物體跟蹤, 幾何形體跟蹤, 基于場景分析的物體建模, 自動景深(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.
