Image-Processing Algorithm with auto pilot project view...

it is based on the leading line concept used by manual pilots when guiding a ship toward the berthisng region within the harbor. In the proposed approach, the leading line is formed by pre-arranging two canvas targets on the quayside, namely a rear green target measuring 145 cm * 100 cm and a front blue target measuring 100 cm * 175 cm. The targets are acquired by a CCD camera mounted on the bow of the boat and the resulting image is transformed from the RGB color space into an equivalent HSV space which more closely resembles the human perception of color. The color space transformations are performed using the following correlations where H, S and V are the hue, saturation and value, respectively, and MAX and MIN are the normalized maximum and minimum values of the R, G and B components. The computed values of H, S and V all lie in the range 0 to 1, and are therefore converted to equivalent values in the range 0~255 in order to enable a greater versatility in specifying suitable threshold values for each component.
