<P>PROBLEM TO BE SOLVED: To provide a vanishing point calculation device capable of stably calculating a vanishing point even when many straight lines are included in an image in addition to straight lines passing through the vanishing point. <P>SOLUTION: Images are prepared as plural learning images, Global feature amounts are calculated from the learning images based on each category, and a discriminator is previously created by leaning the feature amounts. Scene constitution estimation means 21 calculates feature amounts from a taken input image and inputs the resultant in a previously created scene constitution discriminator, and estimates a vanishing point existing candidate area which is a candidate area where a vanishing point may exist based on the category output from the scene constitution discriminator. Vanishing point calculation means 22 detects only straight lines that pass through the vanishing point existing candidate area as a straight line group from an image which has been subjected to a straight line detection on the input image, and determines an intersection point of two major straight lines from the straight line group as the vanishing point. <P>COPYRIGHT: (C)2013,JPO&INPIT |
