Patent ID: 8280105

Claim:
An imaging position analyzing device that analyzes an imaging position of each of multiple frames constituting an image, where the image is captured at preset imaging timings during traveling with a substantially fixed attitude angle relative to ground surface, and each of the multiple frames of the image includes a predetermined continuum captured commonly in at least one of adjacent frames immediately before and after the each frame, the imaging position analyzing device comprising: an input module that inputs image data of the multiple frames; an initial path input module that inputs an initial path of the traveling as an initial value of analysis; and an imaging position analyzer that tentatively set imaging positions of the respective frames corresponding to the preset imaging timings along a moving direction of the initial path and correct the tentatively set imaging positions in a perpendicular direction intersecting with the moving direction of the initial path based on a positional misalignment of the predetermined continuum captured in the each frame and at least one adjacent frame of the image, so as to implement analysis of the imaging position of each frame.
