CRACK ANALYZER, CRACK ANALYSIS METHOD, AND CRACK ANALYSIS PROGRAM
To provide a crack analyzer, a crack analysis method, and a crack analysis program capable of improving the efficiency of crack analysis processing.SOLUTION: A crack analyzer according to the embodiment has a captured image acquisition part, a camera information acquisition part, a crack detection part, an alignment part, and a crack ratio calculation part. The captured image acquisition part acquires a captured image and position information in association with each captured image. The camera information acquisition part acquires camera information. The crack detection part performs processing for generating an ortho image by performing alignment processing based on the captured image and position information and the camera information, and processing for detecting a crack on the road surface from the captured image. The alignment part performs alignment processing based on a structure on the road surface or the background that is reflected in each captured image. The crack ratio calculation part calculates the crack ratio based on the ortho image and the cracks on the road surface detected from the captured image.SELECTED DRAWING: Figure 1
【課題】ひび割れ解析処理の効率化を図ることができるひび割れ解析装置、ひび割れ解析方法及びひび割れ解析プログラムを提供することである。【解決手段】実施形態のひび割れ解析装置は、撮影画像取得部と、カメラ情報取得部と、ひび割れ検出部と、位置合わせ部と、ひび割れ率算出部とを持つ。撮影画像取得部は、撮影画像と、位置情報とを撮影画像毎に対応付けて取得する。カメラ情報取得部は、カメラ情報を取得する。ひび割れ検出部は、撮影画像及び位置情報と、カメラ情報とをもとに、位置合わせ処理を行うことによってオルソ画像を生成する処理と、撮影画像から路面のひび割れを検出する処理とを行う。位置合わせ部は、撮影画像毎に映っている路面上の構造物、又は背景に基づいて位置合わせ処理を行う。ひび割れ率算出部は、オルソ画像と、撮影画像から検出した路面のひび割れとに基づいてひび割れ率を算出する。【選択図】図１
