CleverScan – manhole inspection

CleverScan – manhole inspection

The CleverScan manhole inspection system was developed for one-man operation, mobile use and high productivity. Even manholes that are difficult to access can be easily detected with this system. At the push of a button, CleverScan performs a fast, fully automated manhole inspection in less than 1 minute. This means that up to approx. 50 manholes can be inspected per day by a single person. 

A high-resolution scan of the manhole is created, capturing image details of every centimeter of the manhole wall. The inspection results are photos and videos, a 3D representation and the unwinding of the shaft wall. Furthermore, a dense point cloud is generated, which is used to measure the manhole and can be easily exported to CAD programs. All inspection reports and inspection data can be transferred in the usual data interfaces with all provided characteristic values, e.g. in ISYBAU XML as well as in DWA M-150 format.


Often manholes are difficult to access. In this case, inspection with a camera system installed in a large vehicle is not possible. CleverSan is very well suited for mobile use due to its low weight of only approx. 18 kg. Due to the low overall height of approx. 110 cm, it can also be accommodated in small vehicles (e.g. VW Caddy) – it can also be carried by just one person. The camera system is very light and easy to use, because the software has been perfectly integrated.
