This paper will examine whether information technology solutions can contribute to the work of a road repairer. The aim of the research is to develop an algorithm for identification and volume calculation of the road pits.
The paper presents an overview of three existing methods to identify holes as objects. Recent study uses an ultrasonic sensor to determine the size of a 3D hole; special attention is paid to its noise classification and possibilities for its reduction. The authors have found a way to organize road surface scanning, convert the resulting data into binary code and calculate the volume of the object. Calculations can be made on both a mobile microcontroller-controlled device and a computer after receiving data. A worker, a self-propelled robot or a drone can be used as a sensor carrier.
Study results can be used for further development in the field of transport systems engineering, as well as for mechatronics specialists to develop algorithm realization equipment in a real environment.

The object of the study is an ultrasonic sensor type UT2F/E7-OEUL which measures the presence of a body in the range of 350 to 6000 mm. The sensor was mounted in a suitable place in the combine harvester. Experiments were conducted on three types of waste vegetation mass (WVM): wheat, beans and alfalfa in field and laboratory conditions. A database of sensor measurements was obtained. A single-factor dispersion analysis task was formulated. The results obtained using relevant specialized software showed that the sensor is operational regardless of the type of WVM.
