上記実施の形態では、撮影箇所の所在を示す情報として、撮影対象の画像に撮影箇所をマーキングした画像を生成しているが、撮影箇所の所在を示す情報の形態は、これに限定されるものではない。撮影箇所を特定できる情報であればよい。
撮影対象が複数の区域に区分けされ、かつ、各区域に番地が割り当てられている場合、その番地の情報を利用して、撮影箇所の所在を示すことができる。
撮影対象が、橋梁のような構造物である場合、撮影箇所として指定された箇所のGPS情報(地球上の位置の情報)を所在情報として用いてもよい。
撮影箇所の所在を示す情報として、撮影対象の画像に撮影箇所をマーキングした画像を生成する場合、当該画像を規定のサイズに縮小した画像を生成して、マーキング画像としてもよい。これにより、デジタルカメラ100に当該データを送信等する際の負荷を軽減できる。縮小するサイズは、撮影装置に備えられる表示部の解像度等を考慮して設定することが好ましい。
撮影箇所の所在を示す情報として、番地情報を使用する場合、デジタルカメラ100は、当該番地情報を取得し、背面モニタ122に表示する。この場合、撮影対象の画像も同時に取得し、番地情報と共に背面モニタ122に表示してもよい。
上記実施の形態では、撮影装置をデジタルカメラで構成しているが、撮影装置の構成は、これに限定されるものではない。スマートホン、タブレット型コンピュータ、ノート型コンピュータ等の撮影機能を備えた携帯式の電子機器で構成することもできる。
[構成]
図26は、本発明に係る撮影システムの第2の実施形態のシステム構成を示す図である。
撮影箇所設定装置10で行われる処理については、上記第1の実施の形態の撮影システムと同じである。したがって、ここでは、無人航空機212を用いた撮影方法について説明する。
[構成]
本実施の形態の撮影システムは、指定された撮影箇所を無人航空機で自動撮影するシステムとして構成される。自動で撮影する点以外は、上記第2の実施の形態の撮影システムと同じである。したがって、ここでは、自動撮影を実現するための構成についてのみ説明する。
撮影箇所設定装置10で行われる処理については、上記第1の実施の形態の撮影システムと実質的に同じである。したがって、ここでは、無人航空機212を用いた撮影方法について説明する。
[撮影対象の画像]
上記実施の形態では、撮影箇所設定装置が、撮影対象の画像として、パノラマ合成した画像を取得する構成としているが、撮影対象の画像は、これに限定されるものではない。1枚の画像として撮影された画像を撮影対象の画像として取得することもできる。
上記実施の形態では、撮影箇所設定装置をタブレット型コンピュータで構成しているが、撮影箇所設定装置の構成は、これに限定されるものではない。この他、スマートホン、パーソナルコンピュータ等で構成することもできる。
上記実施の形態では、無人機として、無人航空機を使用して撮影する場合を例に説明したが、本発明で使用可能な無人機は、これに限定されるものではない。無人で地上を走行する無人地上車両、無人で水上を航行する無人水上艦、無人で水中を航行する無人潜水艦、及び、無人で宇宙空間を飛行する無人宇宙機等を使用して撮影する場合にも、本発明は適用できる。また、本発明の無人機には、ロボットの概念が含まれる。
撮影箇所設定装置を実現するハードウェアは、各種のプロセッサ(processor)で構成できる。各種プロセッサには、プログラムを実行して各種の処理部として機能する汎用的なプロセッサであるCPU(Central Processing Unit)、FPGA(Field Programmable Gate Array)などの製造後に回路構成を変更可能なプロセッサであるプログラマブルロジックデバイス(Programmable Logic Device;PLD)、ASIC(Application Specific Integrated Circuit)などの特定の処理を実行させるために専用に設計された回路構成を有するプロセッサである専用電気回路などが含まれる。点検支援装置を構成する1つの処理部は、上記各種プロセッサのうちの1つで構成されていてもよいし、同種又は異種の2つ以上のプロセッサで構成されてもよい。たとえば、1つの処理部は、複数のFPGA、あるいは、CPUとFPGAの組み合わせによって構成されてもよい。また、複数の処理部を1つのプロセッサで構成してもよい。複数の処理部を1つのプロセッサで構成する例としては、第1に、クライアントやサーバなどのコンピュータに代表されるように、1つ以上のCPUとソフトウェアの組み合わせで1つのプロセッサを構成し、このプロセッサが複数の処理部として機能する形態がある。第2に、システムオンチップ(System On Chip;SoC)などに代表されるように、複数の処理部を含むシステム全体の機能を1つのIC(Integrated Circuit)チップで実現するプロセッサを使用する形態がある。このように、各種の処理部は、ハードウェア的な構造として、上記各種プロセッサを1つ以上用いて構成される。更に、これらの各種のプロセッサのハードウェア的な構造は、より具体的には、半導体素子などの回路素子を組み合わせた電気回路(circuitry)である。
