  • 3. Click “Advanced”
  • 4. Click “Download from PC…”

3. IMPORT IMAGES MANUALLY COPIED FROM CAMERA TO DISK (Using DohertyBrowser software)

<For cases where images were manually copied from the camera, rather than automatically downloaded using the DohertyBrowser. This will read the images from a specified location that is treated as if it were the camera plugged into your computer, and copy the images to the “PC Destination:” location. The images can then be used for normal analysis in the browser.>
  • 1. Open the software (as above), and navigate into the main screen
  • 2. Click the “Add” button
  • 3. Click “Browse” beside “SenseCam or Vicon Revue path:”
  • 6. Navigate to the location on disk where you manually copied the participant’s images to, and click on the “DATA” folder
  • 7. Then click “Start”
  • Note that the image directory structure should be the same as on the Vicon Autographer device. i.e.
DATA / <dateFolderContainingImages> & image_table.txt
  • Optionally, you can choose where to store the re-structured image directory too. After step 6, and before step 7, click "Browse" beside "PC Destination:", and then navigate to the desired location.
  • If you wish, you can set the browser to not delete the images from your source file structure/directory. Open the “C:\AidenDoherty\DohertyBrowser\SenseCamBrowser1.exe.config” file, and edit the <add key="autoDeleteImagesOnUpload" value="1"/>” line. The value 1 means the source images will be deleted, the value 0 means they will not be deleted.
