Waterschap Vechtstromen wants an attractive living environment for people, plants and animals. To achieve this, the water board works daily on safe dikes, clean and sufficient surface water and treated wastewater for 800,000 residents and businesses of 23 municipalities in the Dinkel, Regge and Vecht river basin (East and Northeast Netherlands).

Demand

As part of the 'Smart Vecht' project, Waterschap Vechtstromen is looking for a smart camera system that can support enforcers in supervising recreational boating on the Vecht in particular. In practice, it appears that motorboats in particular cause a lot of nuisance on the water.

The process

With the development of the MowHawk we had already built up the necessary experience with smart camera systems. Based on this, we trained a model capable of registering speeding tickets. From this followed the development of a camera system that we installed along a busy shipping point on the Vecht near Hardenberg with the aim of registering speeding violations, as well as the number of boats at certain times, in order to transmit them, for further administrative processing, privacy-proof, to the cloud.

Data

The data comes from camera images. To achieve an accurate velocity determination, we calibrated the images and related them to the position in the real world.

Services

We have developed a tool based on computer vision and sensor technology. With this, the algorithm is able to process camera images and then convert them to the speed at which a boat is traveling via our calibration.

Feedback

The results are displayed through a combination of a Power BI (a dashboard that shows statistics and recent data) and a notification system, which ensures that enforcers receive immediate notification when a speeding violation occurs.

The result

The result is a speed camera for boats that gives enforcers more insight into what is happening in the area (The Vecht) they are tasked to monitor. Based on the statistics, it is also possible for enforcers to act proactively. If the statistics show that the same vehicle commits a speeding violation on the same day of the week and/or at a certain time each time, enforcers can anticipate this. Currently, 1 section control takes place along the Vecht near Hardenberg. In the future it will be possible to work with mobile versions, which will make it possible to check at multiple locations along the river.
