Imager Motion Data Viewer

(Last revision: DOS: Imager.exe, version 1.52k,  25 November 2007;

Windows: Imager98.exe, version 1.13, January 2008)

This page provides access to software for the display, edit, conversion and analysis of motion data obtained from various digitization systems. The program can handle various file formats, including Biomech .DG, .CN and .KM files, Ariel (APAS) .1T and .3D files and Peak Performance .CDA files. In addition, a utility is provided for converting several ASCII file formats to a form suitable for Imager and the Biomech Motion Analysis System. Note, these systems are for planar motion analyses, although three-dimensional data can be viewed one plane at a time.

Files:

  • im152.exe (574 Kb) Self-extracting archive, containing the DOS program, IMAGER.EXE, the installation file, READMEIM.TXT, and sample data for testing the Imager system. The program, CONV2DG, may be used to convert ASCII data files to a form suitable to the Biomech Motion Analysis System.
  • NewIMAGER.EXE (250 Kb) Imager program only. The latest version permits the display of up to 600 frames of data.
  • imager.pdf (999 Kb) Imager User's Manual in PDF format (needs Acrobat Reader). Note, when used with the Biomech system this file should be placed in the MANUALs subdirectory of the BIOMECH directory (e.g., C:\BIOMECH\MANUALS).
  • SAMPLES.ZIP (512 Kb) Self-extracting archive of data files suitable for analysis by Imager and the BIOMECH system.
  •   dg_file.txt (8 Kb) Biomech/Cinedata .DG file format
  • NewImager98.exe (196 Kb) Windows interface to Imager.exe.

    • How to install the system:

    To install, download the IM152.EXE file to a hard disk subdirectory, such as, C:\TEMP. Then execute the following command:

    IM152 -n path

    where "path" is the name of the subdirectory where the software will be installed. If you plan to use this sotware with the Biomech Motion Analysis System (recommended), install them to the same subdirectory, e.g., C:\BIOMECH. You will need, approximately, 1 Mbyte of disk space.

    How to install the data files:

    To install the sample data, download the file Samples.EXE (see above) then dearchive the files to a suitable drive. Note, the archive is divided into many subdirectories so only provide a drive letter, e.g., C: or D:. The archiving software will automatical create the subdirectories. The main directory is called SAMPLES.

    The following activities are included in the archive:

  •  basketball layup and free-throw
  • cart pushing up an incline
  • hurdling and sprinting (male and female)
  • jumping (various)
  • lifting
  • rowing (Gjessing ergometer and on water)
  • running
  • swim starting
  • walking (prosthetic, pathological and normal)
