INVESTIGATION DEVICE, INVESTIGATION PROGRAM AND INVESTIGATION METHOD

摘要

PROBLEM TO BE SOLVED: To suppress comparison of images of different lanes.SOLUTION: A determination unit 33e determines whether a photography position of each of images of video data 32a obtained by photographing a road to be investigated at different periods is within an allowable value on the basis of a photography position of one image for each of the images that the photography position corresponds to. A generation unit 33f generates screen information on a screen where images determined to be within the allowable value are synchronously displayed when it is determined that the photography position is within the allowable value. Further, the generation unit 33f generates screen information on a screen where images determined not to be within the allowable value are not displayed when it is determined that the photography position is not within the allowable value.
