Two low-cost methods of estimating the road surface condition are presented in the paper, the first one

based on the use of accelerometers and the other on the analysis of images acquired from cameras installed

in a vehicle. In the first method, miniature positioning and accelerometer sensors are used for evaluation of

the road surface roughness. The device designed for installation in vehicles is composed of a GPS receiver

and a multi-axis accelerometer. The measurement data were collected from recorded ride sessions taken

place on diversified road surface roughness conditions and at varied vehicle speeds on each of examined

road sections. The data were gathered for various vehicle body types and afterwards successful attempts

were made in constructing the road surface classification employing the created algorithm. In turn, in the

video method, a set of algorithms processing images from a depth camera and RGB cameras were created.

A representative sample of the material to be analysed was obtained and a neural network model for classification

of road defects was trained. The research has shown high effectiveness of applying the digital image

processing to rejection of images of undamaged surface, exceeding 80%. Average effectiveness of identification

of road defects amounted to 70%. The paper presents the methods of collecting and processing the

data related to surface damage as well as the results of analyses and conclusions.
