ExternalChampion_7202022-101145 AM-CHANDLER MANCHESTER

  • The beginning of the video, there is a footage when the camera is lowing into the manhole
  • The distance is reset to zero after the camera is lowered into the manhole successfully
  • The camera is not traveling in the center of the pipe due to obstacles
  • no clock position
  • the annotation occurs when camera is looking at the defect area and not from the perspective view of the defect (with exception of frame that broken got annotated)
  • The distance can be decreasing (locate at the bottom left)
  • The annotation places above where the distance is located
  • at distance 30.0ft, the camera is appeared to get stuck (abandoned survey)
  • The annotation of code is fully written out (e.g: Broken, Crack Multiple, Obstacle Construction Debris, Abandoned Survey)
  • ft appears next to distance when there is annotation
  • There is no access database associated with the video, it will be hard to capture continues defect
  • frame:
    • At the top:
      • Manhole name 1 to Manhole name 2
      • Data (under manhole name 1)
      • Time (under manhole name 2)
    • At the bottom:
      • distance (left)
      • speed (right)
      • annotation appears above distance when code is annotated

  • There are sudden frame jump:
    • at 00:37 from 0.0 ft to 8.0 ft
    • at 5:19 from 52.1 ft to 58.3 ft
    • at 8:35 from around 68.5 ft to 74.0 ft because the camera was caught by root ball
    • at 10:58 from 74.0 ft to 76.9 ft because the camera could not move (was caught by root ball)
    • at 11:22 from 83.5 ft to 244.3ft. The camera started to reverse from the manhole (reverse inspection?) from 244.3 ft to 8.4ft.
  • The camera is not centered most of the time. There are a lot of camera movement.
  • Camera got caught by root balls at 7:51
  • There is no defect annotation appear on the screen.
  • A lot of continuous defects
  • frame:
    • At the top left:
      • Distance
      • Time
      • Date

  • the inspection began at 01:28 at 0.1 ft
  • The distance suddenly change from 4.0 ft to 0.0 ft then to 8.1ft at 01:35
  • There is no defect annotation appear on the screen
  • frame:
    • distance at the top

front-camera/rear-camera

  • upside down
  • no annotation
  • camera moving at fast speed (need to capture more frame in a second)
