As the road surface display image processing device, photographed road surface display image processing manner and the road surface display

摘要

PPROBLEM TO BE SOLVED: To provide a road surface marking recognition device which can recognize a road surface marking better than a case of using a luminance image etc. even in a situation where a shadow superimposes on a part of the road surface marking. PSOLUTION: Light penetrating into a shade has a feature that a percentage of light of the blue system is more than that of a sunny place. A blue component intensity image creating module 103 creates, therefore a blue component intensity image which expresses strength of a blue component from a color image which is output by a color image acquisition module 101, and a shade corrected image creation module 104 adds the blue component intensity image to the luminance image. Thereby, in comparison with the case when using the luminance image, a value of a pixel corresponding to the shade road surface marking becomes large compared with the value of the pixel corresponding to a sunny paved road surface, and in a whole image, the value of the pixel corresponding to the road surface marking and the paved road surface comes to separate into two, and the road surface marking can be recognized with a high degree of accuracy.
