Description of the Invention: [Technical Field] [_1] The present invention relates to an image monitoring apparatus and method, and more particularly to a panoramic camera and a method of monitoring a panoramic image thereof. [Prior Art] 〇 ❹ [0002] When monitoring the road surface, a certain number of IP cameras are generally installed at various intersections of the road surface. Referring to Figure 1, a schematic diagram of monitoring the live condition of the road using a conventional network camera is shown. If there are four network cameras 1 being used for intersection 2 monitoring, you can read these four sets of images on the back end of the network storage server (NAS), and then use the panorama connection technology to make these four The group images are combined into a panoramic image. [00〇3] Since four network cameras 1 are respectively installed at four intersections 2 (as shown in Fig. 1), it is necessary to separately provide four power sources. In addition, the image data must first be transmitted through a network hub (HUB), and then connected to the network storage server at the back end to store image data. When the user views the monitoring screen of the intersection 2, the four groups of images are first passed through the video decoder and then combined into a panoramic image by the panoramic connection module for the user to watch. If there are a large number of users watching, the panorama connection module will be overloaded and the number of viewers available will be reduced. SUMMARY OF THE INVENTION _ In view of the above, it is necessary to provide a panoramic camera that can simplify road construction procedures, line layout, and reduce circuit and wire costs while monitoring Wang Jing images. At the same time, it can reduce the usage rate of network bandwidth and increase the use.
