Other AbstractUnder the unstructured outdoor lighting environment, robust recognition and accurate interpolation of structured laser light were still challenging in the application of road flatness measurement. For obtaining more robustness to the disturbance of shadow and landmarks, a laser line recognition method was proposed by utilizing rigid item constraint active contour model. To reduce the sensitivity of the initialization of the active contour model, the cubic spline algorithm was employed for more accurate curve interpolation. A rigid item constraint described by the second derivative of arc length was appended to the energy functional definition to ensure the smooth curve evolution and effectively restrain the curve stretch. With fixed parameters, the experimental results of real images that included the extreme disturbances of shadows, white indicator line and poor road flatness validated the efficiency and robustness of the proposed method.
