翻译： 软件版本三大功能： 1、消除镜头变形失真 视频（含图片串和视频文件）真实镜头的变形可以被还原， 并且不需要额外的参照物， 不破坏原始画面，可以将结果保存到硬盘上。 2、视频计算 可以通过自动或者半自动的方式计算出， 视频中摄象机的位置，转角，以及镜头的焦距。 特性： 跟踪匹配镜头的自由移动和推拉摇移等 可以对合成文件操作 自动或者半自动计算 可以手动微调 支持电影文件 可以输出2D或者3D的镜头轨迹（Lightwave, 3DS Max, Maya, Softimage, Houdini, Cinema-4D (via Lightwave), After Effects, Truespace, Combustion, Flame/Inferno[居然高级到支持FLAME和INFERNO]） 能够识别NTSC的分场 可以设定关键帧跟踪和全部跟踪（Garbage matte support呵呵，这个不会翻） 可以自动产生马赛克 优化跟踪轨迹 在镜头平移的画面中能分割出物体的运动轨迹片段 3、场景重建 根据计算结果重建视频场景，可以保存的场景格式为VRML97, Lightwave, 3ds Max, Maya and MGF等。（估计对简单场景有效果） 英文介绍： The current version of the software comes as three separate components: Lens Distortion Removal Geometric lens distortion may be estimated from images or video sequences, using simple interactive techniques. No calibration grids are required, and video and image sequences may be distorted/undistorted and saved back to disk. Image and Video Sequence Calibration Intrinsic and extrinsic camera parameters (e.g. camera position, orientation, focal length etc..) may be estimated using automatic and semi-automatic approaches. Features: Matchmoving for free-movement and pan/tilt/zoom camera motions Single and multiple image calibration Automatic and semi-automatic feature tracking Manual motion-tweaking facilities Cineon image file support 2D and 3D tracking export (Lightwave, 3DS Max, Maya, Softimage, Houdini, Cinema-4D (via Lightwave), After Effects, Truespace, Combustion, Flame/Inferno, and human readable text) Support for NTSC pulldown removal, multiple interlacing modes and image processing operations for building good tracking plates. Garbage matte support, including keyframing and automatic tracking Automatic mosaic generation 2D and 3D video sequence stabilization Motion segmentation to remove moving objects from panning video sequences (beta) Geometry Reconstruction Once image or video data has been calibrated, interactive techniques are used to reconstruct geometric models of environments. Surface textures may also be extracted from the image data, and models may be saved in VRML97, Lightwave, 3ds Max, Maya and MGF formats.
