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。
Already the industry-leading 3D camera tracking and matchmoving application, PFTrack 2012 introduces innovative solutions to the diverse challenges of advanced matchmoving faced by independent artists, and large visual effects teams working within complex creative pipelines. From extensive plate preparation tools and renowned lens distortion management, through single-camera and stereoscopic 3D camera tracking, image-based modelling and scene reconstruction, PFTrack 2012 sets a new benchmark as the most complete toolset available, with unprecedented levels of power, precision, flexibility and control over every aspect of the matchmoving process.
Featuring The Pixel Farm’s distinctive node-based flowgraph architecture, PFTrack 2012 introduces revolutionary approaches to camera and object motion calibration, scene preparation, project management and data flow, opening new doors to how the information generated by matchmoving can be utilized and exploited facility-wide. With fully-integrated Python scripting and workflow customization tools, facilities can access the underlying metadata management core of PFTrack 2012 and tightly integrate the software to their own unique workflow.
PFBarrel for Nuke
Significantly enhances the lens workflow between The Pixel Farm’s products and The Foundry’s Nuke compositing application. Lens data exported from PFTrack can be imported into Nuke through the PFBarrel plugin, allowing all calibrated lens data to be manipulated and utilized in a number of ways. The most obvious use of PFBarrel is to apply the dynamics of the original lens to rendered CG layers when compositing them with the live action plate.
Z-depth
The Z-depth node now allows Z-depth to be calculated for a single frame, and then tracked through the sequence to significantly accelerate the creation of depth data. The Merge tool may then be used to analyze the calculated Z-depth, merge it across multiple frames, and produce a smoother transition of depth values frame-to-frame.
Reporting UI
An integrated web browser has been included which provides direct access to Software Maintenance and Operational Support subscriptions from within the application. When support is required, the web UI will transmit information about the workstation, along with the software log, to assist with diagnosis of problem. Bug reports and feature requests may also be made, the status of which will be reported back throughout the development cycle.
