The image capturing unit 122 is, for example, a complementary metal-oxide semiconductor (CMOS) image sensor or a charge coupled device (CCD), and can be used to take an environmental photograph. The first communication module 124 can transmit the environmental photos obtained by the image capturing unit 122. The 'in the foot server'' is used to press the HS: the first photo of the communication module m. The transmission of the polar communication photos by the first communication module 124 and the second communication module 132 can be achieved by. For example, the positioning system of the present embodiment may further include a multimedia message server 14G, between the first communication module 124, and a multimedia information UVMultimedia Messaging Service (MMS). In respect, the image feature comparison 134 is consumed = and the database 110. The image feature comparison mode is used to capture the image of the environment after the 4 2 communication module (3) receives the environment photo, and the image features of the environment photo 7 201024674 xal, u»uzu4.TW 29780twfdoc/n, and can be based on the image of the environment photo The feature map is compared to the panoramic map database 110 to find geographic information of the environmental photos. Since image recognition and comparison technology is a major technology of today's artificial intelligence, it is the focus of current people's attention and investment, such as fingerprint recognition, portrait recognition, eye recognition and other fields. Therefore, the present embodiment can be matched with the existing image recognition comparison technique to match the environmental photo and panoramic map library 110. When the geographic information of the environmental photo is found, the second communication module 132 can establish and send another multimedia message back to the first communication module 124 of the handheld device 120 according to the geographic information of the environmental photo. 2 is a flow chart of a positioning method according to an embodiment of the present invention. The flow of the clamping method will be described below in conjunction with the positioning system 100 of Fig. 1 and steps S2〇2 to S2〇6 of Fig. 2. Please refer to Figure 2 and Figure 2 at the same time. First, the user can find a typical representative image in the environment in which he is located, and take an environmental photograph by the handheld device 120 (step S2〇2). Next, the characteristic capture of the environmental photograph is performed by the fixed server 130 (step S204). Thereafter, the position feeding device 130 performs a feature comparison between the environmental photos and the typical climbing images in the panoramic map database 11〇. When the location server 13 finds the corresponding photo, it returns the geographic information corresponding to the photo to the user, so that the user can get the location of the month J or the surrounding traffic, food and other information (step s) . Face 3 is a flow chart of the positioning method of another embodiment of the present invention. The following two brothers, the positioning system 1〇〇 of Fig. 1 and the steps S310 to S374 of Fig. 3, go into the flow of the positioning method. Please refer to Figure i and Figure 3 at the same time. έ p first 'creates a panoramic map database 110 as in step S310'. Details, ,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,, 8 201024674 IAC080204.TW 29780twf.doc/n First, step S312 is performed to obtain a panoramic map corresponding to a map range. For example, many map sites on the Internet today offer full-map services. In these map websites, the building appearance, the location of the building, the street name and the house number are all linked together. The information volume of the map is large, and the data is also very detailed. Therefore, the step of obtaining the panoramic map in the embodiment can be completed by using the existing map data, and can be widely applied. Then, in step S314, a plurality of typical images are obtained from the panoramic map. For example, in the panoramic map corresponding to the map range (in the figure, there are a plurality of typical images, such as the building 410, the bank 420, the police station 43〇, the appearance of the stadium 440, the house number, the location, the street name) Then, step S316' is performed to store the correspondence between these typical images and the geographic assets in the map range (step S316) to establish a panoramic map database ho. ' For example, the panoramic map database 110 may correspond to these typical The image records the latitude, longitude, surrounding traffic, food and other information of the location of the typical image to establish a complete map database. After completing step S310, step S320 can be performed to pass through a handheld device 120. The image capturing unit 122 captures an environmental photo. The handheld device 120 is, for example, a mobile phone having a camera function. When shooting, a typical image of a building, such as a house number plate, a building name plate, an appearance, a company store, can be found. Brand name or other typical image, etc. Then turn on the camera function of the handheld device 120, and adjust the distance or use the zoom to make the decision mark For example, FIG. 5 is a schematic diagram of an environmental photograph taken by the handheld device according to the consistent embodiment of the present invention. When taking the environmental photograph of FIG. 5, it may be outside the building. As a typical image, 9 201024674 1ACU «U^U4.TW 29780twf.doc / n try to fill the entire building as much as possible. After that, the first communication module 124 in the handheld device 120 can take the photo taken The 81-piece attachment is included in the Multimedia Message and sent to a multimedia message server 14 (step s33〇). After receiving the message, the multimedia message server M0 determines that the multimedia message is =--special format This special format can be used when transmitting multimedia messages to 'enter specific text or symbols in the message content to distinguish other media messages sent by the sender. For example, m is input from the branch at the end of the message: ΑΡ, Different from the multimedia message. When judging that the multimedia message format %•' multimedia message server 140 turns the multimedia message to the fixed server 130 (step S340), the positioning server 130 The f group 132 can receive the ΐ photos transmitted by the multimedia message server 140. In this embodiment, the multimedia message is used as the transmission environment, and the first, 'but the actual application is not limited thereto, and the 匕 也 can also be utilized. &=, to the purpose of transmission, for example: EmaU. ❹ Photo ^ 疋 ^ feeding machine, please receive the environment taken by the handheld device 120 to take the day position Wei 1 ^ 13G in the image feature set module 134 will be two = image feature (steps, for example, in Figure 5), the second communication module 132 in the positioning server 130, the second image feature comparison module 134 can capture the image 5 characteristics of the built-in table. For example, in the upper part of the building, there is a step = "--square, and the existing shirt image processing is used to complete the construction, and will not be described here. For example, in step S360, the image feature comparison module 134 According to the image features of the environment 201024674 IAC080204.TW 2978〇twf.doc/n photos, the panoramic map database 11 is compared to find the geographic information of the environment..., the slice. In detail, step S360 may include step S362 and Step S364 and other two sub-steps. First, step magic 62 is performed, and the image feature comparison module 134 compares the environmental photos with the typical images in the panoramic map database 11〇. When the comparison module 134 compares the ambient photo with at least one of the typical images, the image feature comparison module 134 can find a typical image similar to the ambient photo in the panoramic map database 11 Corresponding geographic information (step S364). For example, comparing the typical image of the building 410, the bank 42〇, the police station (4), the stadium 440, and the like in FIG. 4 with the buildings in the environmental photo of FIG. 5, Figure 41 in the building in Figure 4 The buildings in Fig. 5 all have a square shape in section, and a feature of the stage difference in the upper part of the building. Then, the image feature comparison module 134 can find the geographic information corresponding to the building 41. For example, The website server is used to mobilize the map search system to find the relative position of the building 410 and its typical image, as well as the adjacent street name, etc. Then the 'positioning server 13 〇 returns the geographical information of the environmental photo to the handheld device 120 (step S37〇). In detail, after the geographic information of the environment photo is found, the second communication module 132 in the location server 130 can establish another multimedia message according to the geographic information of the environment photo (step S372), and Another multimedia message is sent to the handheld device 12 (step S374). In addition, the present invention can achieve a simple navigation function through cooperation between the positioning server 14 and the website server. For example, it can be used as a starting point 11 201024674 iacu»u ^U4.TW 29780twfdoc/n, route planning, find the nearest arrival route. For example, in Figure 4, to find out from the building 410 The shortest path of the 44-inch building can be used to transfer the surrounding map of the building 44〇 and related traffic information by the full-site map server, and then packaged by the second communication module 132 in the positioning server 13〇. For the mobile phone user, the hand-held household receives the replying multimedia message, and can understand the location and related geographic information. In summary, the present invention can be combined with the detailed database of the panoramic map website=the existing image recognition comparison The technology can make the user's mobile phone have a simple navigation and positioning function. The timely identification of the user's location can well guide the user's travel.
