Description
図1に示すように、本例の映像監視システムは、複数の被監視サイト11〜1n、管理サーバ6及び複数の監視サイト131〜13mが、ネットワーク回線2に接続されて構成されている。ここで被監視サイト11〜1nは、通常駅舎やビルなどの建物を指しており、被監視サイト11〜1nを総称して述べるときには、被監視サイト1という。または図1に示す実施の形態例に合わせて単にビル1ということもある。また、複数の監視サイト131〜13mを総称して述べるときには監視サイト13という。 As shown in FIG. 1, the video monitoring system of this example is configured by connecting a plurality of monitored sites 1 1 to 1 n , a management server 6 and a plurality of monitoring sites 13 1 to 13 m to a network line 2. ing. Here, the monitored sites 1 1 to 1 n refer to buildings such as normal station buildings and buildings, and the monitored sites 1 1 to 1 n are collectively referred to as monitored sites 1. Alternatively, the building 1 may be simply referred to in accordance with the embodiment shown in FIG. The plurality of monitoring sites 13 1 to 13 m are collectively referred to as the monitoring site 13.
また、制御部8は、複数のカメラ4からの画像データの中で、同じ値となる2点が重なりあう際の時間差によって、フレームレートを変更する。例えば、1fps(flame per second)の場合、1秒毎に1フレームの映像を表示するのであるが、ネットワーク要因などにより、2秒毎に表示する必要がある場合には、合成処理するフレームは、2fpsに変更されることになる。 Further, the control unit 8 changes the frame rate according to the time difference when two points having the same value overlap in the image data from the plurality of cameras 4 . For example, in the case of 1 fps (flame per second), one frame of video is displayed every second. However, when it is necessary to display every two seconds due to network factors, the frame to be synthesized is It will be changed to 2 fps.
CPU21は、本例の映像監視システムに関係する管理サーバ6の各部の機能を実現するソフトウェアのプログラムコードをROM22から読み出して実行する。RAM23には、管理サーバ6内で行われる演算処理の途中で発生した変数等が一時的に書き込まれる。CPU21がROM22に記録されているプログラムコードを実行することにより、管理サーバ6内の各種機能が実現される。 The CPU 21 reads out the program code of the software that realizes the functions of each unit of the management server 6 related to the video monitoring system of this example from the ROM 22 and executes it. In the RAM 23 , variables and the like generated during the arithmetic processing performed in the management server 6 are temporarily written. Various functions in the management server 6 are realized by the CPU 21 executing the program code recorded in the ROM 22.
図4は、画像合成用カメラ4aからの画像データを管理サーバ6内で処理した後のデータ構造のテーブル例を示す図である。
図4には、画像データフィールド12c、現地時間フィールド12dの他に、管理サーバ6における画像の合成処理が完了した時間を記す合成完了時間フィールド12eが示されている。この合成完了時間フィールド12eは、図1に示すデータベース12の合成完了時間エリア12eに相当するものであり、図4でも図1の合成完了時間エリア12eと同じ記号を用いている。なお、図4では、カメラ4a画像のみを示しているが、カメラ4b画像及びカメラ4c画像についても同様な処理が行われることは言うまでもない。
FIG. 4 is a diagram showing a table example of the data structure after the image data from the image composition camera 4a is processed in the management server 6.
4 shows, the image data field 12c, in addition to the local time field 12 d, synthetic completion time field 12e mark the time the composition processing is completed in the image are shown in the management server 6. The synthesis completion time field 12e corresponds to the synthesis completion time area 12e of the database 12 shown in FIG. 1, and the same symbols as those in the synthesis completion time area 12e of FIG. 1 are used in FIG. In FIG. 4, only the camera 4a image is shown, but it goes without saying that the same processing is performed for the camera 4b image and the camera 4c image.
また図6Aには、画像合成釦16Eが設けられ、この画像合成釦16Eにタッチすることにより、画像合成用カメラ4a〜4cからの3つの画像が合成されて、図6B、図6Cに示すような全画面16F表示に切り替えられる。 In FIG. 6A, an image composition button 16E is provided. By touching the image composition button 16E, three images from the image composition cameras 4a to 4c are synthesized, as shown in FIGS. 6B and 6C. Can be switched to the full screen 16F display.
被監視サイト1の通信装置3は、管理サーバ6からの送信要求を受信し(ステップSC1)、画像合成用カメラ4a〜4cに現地の画像データを取得させるか、あるいは予め取得されて記録装置5に記憶されている画像データを現地の画像データとして取得する(ステップSC2)。
そして、被監視サイト1(ビル1)内の通信装置3から、ネットワーク回線2を介して、現地の画像データが管理サーバ6に送信される(ステップSC3)。
The communication device 3 of the monitored site 1 receives the transmission request from the management server 6 (step SC1), and causes the image composition cameras 4a to 4c to acquire local image data or is acquired in advance and recorded by the recording device 5. Is acquired as local image data (step SC2).
Then, local image data is transmitted from the communication device 3 in the monitored site 1 (building 1) to the management server 6 via the network line 2 (step SC3).
