From Saturday, road workers start photographing and scanning streets. On their basis, a three -dimensional model of Warsaw roads will be built. This will allow officials to carry out precise measurements without going out of the desk and identify all facilities, including road signs and advertising.
From Saturday, February 8, on the capital's roads you will be able to meet a car with cameras and a roof scanner. Over the next few weeks, he will photograph and scan 800 kilometers subject to streets and an adjacent area up to 21 meters from the edge of the road.
Orthophotomapa and three -dimensional road model
– With the help of these photos and scans we will create an orthophotomap and three -dimensional road model – your own and definitely more precise equivalent of Street View. This is a pioneering solution not only in our native yard, but probably also in Europe – said the spokesman for the Municipal Road Administration Jakub Dybalski.
He also explained what the Warsaw model would differ from Street View from Google, which allows you to look around the road from the road.
– First of all, Street View are ordinary spherical photos of standard quality. Often, photos of individual roads are not valid. There are also different breaks between one and the other photo that is used when creating a continuous image. As a result, we do not always have the opportunity to set ourselves exactly where we would like – noted Dybalski.

In turn, photos for the needs of orthophotomaps prepared by road workers will be taken in resolution enabling reading from a distance of 15 meters of inscriptions from a font with a height of five centimeters. The entire 800 kilometers of roads will be photographed at a certain time.
– Thanks to this we will have a current picture for all streets. In turn, the distance between taking subsequent photos will not exceed five meters. In addition, each photo will have to be associated with geographical coordinates with an accuracy of 10 centimeters – explained ZDM spokesman.
The algorithm will recognize objects on the road
Roads will also be scanned in three dimensions, which will create so -called Points clouds. Thanks to them, not only the streets and the road lane will be thoroughly reproducing, but also all scanned objects with an accuracy of two centimeters.
A special algorithm will recognize objects – road signs and horizontal marking, poles, signaling devices, technical boxes, but also ads and other facilities placed on the road.
The detected objects will be additionally illuminated, and after clicking, detailed data about them will be displayed. Each of these objects will be properly described – the algorithm will recognize, for example, the content of the road sign.

– Hence the straight path to control, which ads operate without permission. Such a model also greatly facilitates design, shortening the time needed to inventory the current state. The model will also allow quick verification of the road cross -section, including the height of the curb, decrease and direction of water outflow or unevenness in the surface – noted Dybalski.
He said that the scanning of Warsaw roads would last until March. Its effect will be an orthophotomap. It will be prepared by a Polish-Dutch consortium selected in the tender consisting of the Warsaw company Smart Factor and Cyclomedia, whose offer was PLN 1.2 million.
