The improvement of transport on the road arteries presupposes, first of all, the best possible quality of the asphalt carpet. In this sense, they developed standards regarding the quality of practical asphalt carpets on road arteries and created a series of systems and devices placed on vehicles to determine the asphalt carpets' compliance with these standards. These systems are made, more recently, with lasers that illuminate the asphalt carpet, in the form of lines perpendicular to the direction of movement of the vehicles intended to control the quality of the asphalt carpets, and with the help of cameras, the images reflected by the asphalt carpet are applied, following a further processing of the images. Selected A problem, very important in the development of this process, is the triggering of the time-lapse cameras, determined by the speed of movement of the control vehicles, which means a very precise sampling of the distances of the road arteries. In this, we do not propose to implement a dedicated software in a microcontroller, theoretically study and practically determine a non-conventional search camera triggering system at the very well-established time interval with an error of less than 10-4..
