DigiSewer in Action

DigiSewer converts an analog video signal into a digital scan for higher-resolution screen presentation than conventional CCTV.

DigiSewer: Similarities to CCTV

• Same equipment, similar workflow• No special setup, deployment or operation• Data easily integrates with inspection reporting software, asset databases• Same steerability and crawler performance as conventional CCTV.• Inspection results available immediately.

DigiSewer: Advantages Over CCTV

• DigiSewer is faster than conventional CCTV (70 fpm vs 30)• DigiSewer uses digital storage more efficiently (16,000 ft on a single DVD)• No stopping or panning/tilting for defects• Accurate and detailed annotation• Lower cost of ownership• Consumes less digital capacity/bandwidth for archiving and sharing

System Components: Crawler

A versatile platform:

• Steerable• Multi-function: perform traditional pan/tilt inspection and DSS

interchangeably• Low-maintenance

System Components: Camera

• DigiSewer’s wide-angle lens and LED light array allow 3 levels of illumination intensity.

• Camera captures evenly lit cross-sectional images in pipes of varying diameter (6-60”).

System Component: Computer

• The CPU digitally unwraps cross-sectional images and stitches them together into one long scan whose height corresponds to pipe diameter, and whose length corresponds to the length of the pipe.

System Component: Software

• Ability to view Scan Data in three different views: Sidescan View, Front View and Thumbnail View.

System Components: Software

• Accurate location and measurement using 2D and 3D measurement

System Components: Software

• Zoom and measure from 50-150%. (Scan captured at 70 fpm.)

System Components: Software

• Quick review using software• Defects highlighted can be seen on the thumbnail view.

System Components: Software:

Color-coded to highlight PACP classification of observations in thumbnail view.

• Yellow: Construction• Red: Structural• Green: Operational/Maintence• White: Misc.

System Components: Software

• On-Screen Inclination is captured during scan

System Components: Software

• Automatic recognition of joints and taps

System Components: Software

• WinCan v8 exports projects to freeware WinCan viewer for a quick yet detailed analysis.

• No installation of software is needed, simply insert DVD or flash drive into any PC.

• Export data in WRC, PACP and ASCII formats.

Data Integration

DigiSewer data easily integrates with the following GIS/work order software:

• Arc View• GBA• Hanzen• Maximo• Citiworks/Azteca

Future of Digisewer

• Digisewer with Manhole Inspections.
