FIELD: physics. ^ SUBSTANCE: distance from traffic mark line to vehicle and angle of vehicle departure from said line are measured by one optical locator. Motorway surface digitised images are processed. Two identical points R1 and R2 closer to vehicle are selected in image field at apices of traffic mark dotted line. Coordinates of said points are defined on light-sensitive matrices (Yà,Zà), m, where à=1, 2 is number of points R1 R2, respectively. Lateral departure from dotted line and angle between vehicle lengthwise axis and traffic mark line are determined. ^ EFFECT: distance from traffic mark line to vehicle and angle of vehicle departure from said line are measured by one optical locator. ^ 3 dwg |
