Integrated video software can take it to the next level   

 

While data acquisition has proven to be vital in reducing elapsed times, increasing speed and race car reliability, the introduction of low cost video cameras has changed the data analysis process.    

No longer is data confined to a one dimensional set of squiggly lines on a computer display. Instead, the ability to import and sync video, in conjunction with those squiggly lines, has added a third dimension to the data analysis process.

To explain the process, let’s first take a look the process for downloading and graphing data from a Racepak data logger. Upon completion of the run, the vehicle is returned to the pit area. The Racepak data is downloaded through a download cable or cartridge (V300, V500 or UDX logger dash products). The third method is to remove the SD memory card from the data logger (V300SD or Sportsman logger), insert the memory card into the user’s PC, at which time the data is downloaded and converted into a runfile.

The last step in the process is to open the runfile, graph a data channel (typically driveshaft or accel G) and “zero” the run. This “zero” process allows the customer to accurately overlay data from various runs, with all data starting from the 0 time point (when the vehicle leaves the starting line).

Racepak’s integrated video software is designed for use with any type of video camera recording to a removable memory card. The video formats can be mpeg4, avi, mov or any other video formats associated with removable memory cameras.  Once the Racepak runfile is downloaded, and the zero point set, the customer simply removes the video camera memory card, inserts the card into the PC card reader, and with the Racepak runfile still open, select the IMPORT VIDEO button in the Racepak runfile


Tim Anderson, general manager at Racepak is always happy to provide  teams with technical advice  

Once imported, a video window is opened in the Racepak runfile. The video is easily synced to the runfile, by simply moving the video to the initial movement of the car from the starting line, moving the data cursor to the zero point in the data (which is the initial move of the car from the starting line) and selecting the ACCEPT button.

This action then ties the video to the runfile and the cursor position in the graphed data. As the cursor is moved across the graph area, the video moves in sync with the cursor, allowing frame by frame analysis of the video, in conjunction with the data.  If the runfile is closed and reopened, the video file can be recalled, with the sync point always saved.

To further simplify the video process, Racepak offers a camera sync V-Net module. Plugging into the V-Net cable the same as any Racepak V-Net sensor, this module connects to the new Replay HD video camera, sending at start record signal to the camera at the same instant as the data logger begins recording. This action eliminates the necessity of manually syncing the video with the runfile, inside the Racepak software.

Racepak’s integrated video, Replay HD camera and Replay V-Net trigger module will be available in early 2012.  Racepak’s integrated video software. See data in an entirely different dimension.

I wish You all happy Christmas holiday and look forward staying in touch 2012!
