Document Type and Number:
Japanese Patent JP2989744
Kind Code:
B2
Abstract:
A measurement face extraction apparatus extracts a measurement face such as a road area in three-dimensional space. The measurement face is continuously located in the three-dimensional space. In the apparatus, two cameras input two images each of which includes the measurement face. A conversion unit calculates an equation of a projection plane corresponding to the measurement face and projects each position of each image onto the projection plane. A memory stores image information of each position of the two images by unit of projected position on the projection plane. An extraction unit, extracts each projected position for which the image information of the two images are similar from each projected position of the memory as the measurement face on the projection plane.
