The landmark list lists at least one landmark material in the road map data of the planning route. The camera device captures the image in front of the moving object as a video image during the navigation process, and the navigation interface prompts the planning path in a guiding mode. The moving object is carried along the planned path. The comparison module compares the image captured by the camera with the landmark data to be traveled on the planned path. If there is a feature in the image that matches the landmark data, the navigation interface is The way to include information about landmark information suggests a planning path. [0007] For the purpose of the present invention, a navigation method for guiding a navigation system is provided for guiding a mobile object to a destination via a planning path, which includes the steps of: providing a road map database to store a plurality of road map data and a plurality of landmarks Data; use the landmark list to list at least one of the landmark data in the road map data; use the camera to capture the image in front of the moving object in the navigation 099137385 Form No. A0101 Page 4 / Total 16 Page 0992065175-0 201217753 The image captured is - the image map m is compared with the (4) group according to the image of the camera device and the landmark data to be passed on the planning path; when there is a feature in the image image that matches the landmark data Then, the second interface: the navigation interface prompts the planning road scale with the information related to the landmark information [_ where the 'S comparison module determines the image picture + does not have the feature of the landmark finger bow I, then the navigation interface does not contain The planning route for the relevant information of the landmark information. 1 闺 巾 , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , [0010] wherein, if the comparison module determines that the features of the image image and the landmark data do not match, the navigation interface displays the planned path without the relevant information of the landmark information [0011] wherein the comparison module Furthermore, the image recognition unit is included, and the image recognition sheet _ is included in the outline, color or image image of the image image to achieve landmark recognition. [0012] wherein, the image processing unit further includes the processing of the image image in a large and clear manner to facilitate clear display in the navigation interface. [0013] With the 'navigation system of the present invention and its navigation method, one or more of the following advantages: It may have [0014] (1) by means of the navigation system and its navigation method, with landmarks Whether the feature is 099137385 Form No. Α0101 Page 5 of 16 〇992〇65175-〇201217753 It can be determined by the user to determine whether to provide relevant information about the landmark information of the intersection to the user. Let the user avoid the doubt that the information does not match when making a turn at the intersection. [0017] [0017] 099137385 (2) at the intersection of 4 road junctions, using the image capture navigation system and its navigation method, in order to achieve the effect of the complex multi-junction quasi-breaking prompts to enhance the user's multiple routes The clarity of the mouth and the shock, and then increase the safety of driving. [Embodiment] Hereinafter, the same components as in the following embodiments will be described with the same reference numerals in order to facilitate understanding of the embodiments of the navigation system and the navigation method thereof. 1 is a block diagram of a navigation system of the present invention. As shown in the figure, the road map database 11, the landmark list 1 2, the camera device 13, the comparison module 14, and the navigation interface 15 are included. The navigation system is used to guide the moving object to a destination via a planning route. The road map resource library 11 has a plurality of road map materials and a plurality of landmark materials. The landmark list 12 extracts at least one landmark in the planned route from the road map database 11 and arranges the order of the landmark data according to the planned road control. The camera device 13 captures an image in front of the moving object during the navigation process as an image picture 21. The image recognition unit 141 in the comparison module 14 compares the outline or color of the image image 21 with the landmark data to be traveled on the planned path according to the camera device 13 to achieve landmark recognition. The navigation interface 15 prompts the planning path in a guided mode to cause the moving object to proceed along the planned path, such as "front 7-11 right turn". Based on the above, the camera unit 13 will continue to capture the planning route during the navigation process. Form No. Α0101 Page 6 of 16 0992065Π5-0 [0018] 201217753 影像 The image in front of the moving object is the image picture 21. Therefore, when the user of the navigation system 1 approaches a slogan or an intersection, the image recognition unit 141 first confirms whether the captured image 21 is a landmark guide feature (such as a convenience store, a fast food restaurant, a traffic light, a traffic sign). , advertising signs, store signs, etc.). If it is not a landmark feature, the navigation interface 15 will prompt the planning path in a manner that does not include information about the landmark information. Moreover, if the comparison module 14 does not complete the recognition of the image feature within a predetermined time (if the time point at which the landmark guidance feature should appear is not recognized), the navigation interface 15 does not include the intersection landmark. The way of information related information prompts the planning path. (In the present embodiment, the predetermined time may be a short period of time before the time point when the landmark guiding feature should appear, but the present invention is not limited to such an embodiment in actual implementation). [0019] If the image recognition unit 141 confirms that the captured image image 21 is a landmark guiding feature, the comparison module 14 determines whether the landmark guiding feature in the image image 21 and the planned path listed in the landmark list 12 are about to pass. The landmark information is consistent. If the matching feature matches, the comparison module 14 sends a first guiding signal to the navigation interface 15, and the navigation interface 15 prompts the planning path according to the first guiding signal to include the relevant information of the landmark information, for example, "the front 7-11 turns right. ". If the matching feature does not match, the comparison module 14 sends a second guiding signal to the navigation interface 15, and the navigation interface 15 prompts the planning path according to the second guiding signal without including the related information of the landmark information, for example, "300 meters ahead" Please turn right." In further detail, in this embodiment, the navigation interface 15 further includes a display interface 151 to display a planned path, and when the comparison module 14 compares the image picture with the upcoming 099137385, the form number is Α0101, page 7 / total 16 pages 0992065175-0 [0020] When the landmarks of 201217753 are marked, the image processing unit 142 enlarges and clears the image 21, and the display interface 151 includes the information related to the landmark information according to the first guiding signal or the processing by amplification and clarity. At least some of the image images 21 suggest a planning path. As shown in Figures 2 and 3, the display interface on the right side of Figure 2 has a landmark data associated with Λ (e.g., 7-11); and the display interface on the right side of Figure 3 has at least a portion of the image. The way of the two embodiments is to prompt the planning path. When the comparison module 14 does not match the image data of the upcoming landmark image, the display interface 151 prompts the planning according to the second guiding signal without including the landmark breeding related information or at least a part of the image image 21. path. In addition, the navigation interface 15 also includes a 152 audio playback device for guiding the path by sound. When the comparison module 14 matches the image feature of the upcoming image, the sound playback device 152 includes the first guide signal according to the first guide signal. The way the landmark information is related to the sound guide planning path. When the comparison module 14 does not match the image feature of the upcoming image, the sound playback device 152 vocalizes the planned path according to the second guidance signal without including the landmark information related information. [0021] When the user of the navigation system 1 approaches a complex multi-junction, if the image captured by the camera device 13 is confirmed as a landmark guiding feature, the comparison module 14 determines the landmark indication in the image 21 Whether the feature matches the landmark data to be traveled by the planned path listed in the landmark list 12, if the matching feature matches, the comparison module 14 further determines that the landmark guiding feature is at the turning point, and then displays the interface 151 to include the landmark information. The information or at least part of the image 21 indicates how the user of the navigation system makes a turn at the turning point, and the sound playback device 丨52 will also make a relative 099137385 Form No. 1010101 Page 8/16 pages 0992065175-0 201217753 [0022 〇[0023]〇[0024] Prompt for Reaching; Complicated Multipathing FIG. 4 is a schematic flow chart of a navigation method of the navigation system according to the first embodiment of the present invention. The navigation method of the navigation system is used to guide the moving object to a destination via a planned path. Please refer to FIG. 4, firstly, as shown in step S31, the user uses a navigation system, which provides a road map resource library, a landmark list, a camera device, a comparison module, and a navigation interface. The road map database stores a plurality of road map data and a plurality of landmark materials. The landmark list lists at least one landmark data in the road map data of the planned route. The camera device captures the planning road control during the navigation process, and the image in front of the moving object is the image peripheral film. The comparison module applies the image recognition unit according to the camera device to capture the outline or color of the image image and the planning path is about to pass. The landmark information is compared to achieve the identification of the landmark. The navigation interface prompts the planning path in a guided mode to move the moving object along the planned path. Then, as shown in step S32, the camera device captures the image image during the navigation process. Then, as described in step S33, when the user approaches a τ word, an intersection or a complex multiple intersection, the navigation system first confirms whether the image captured by the camera is a feature of a landmark (such as a convenience store, fast food). Shop, traffic lights, traffic signs, advertising signs, store signs, etc.), if not a landmark feature, proceed to step S34. S34: The navigation interface prompts the planning path in a manner that does not include information about the landmark information of the intersection. In this way, the user will not hear the landmark information of the turning point originally built in the navigation system, and eliminate the change of the location of the landmark identifier or the accurate prompt of the ground. 099137385 Form Α Α 0101 Page 9 of 16 0992065175-0 [0025] 201217753 The subject is obscured, the user can't see the landmark identifier but hears the information that the navigation guide does not match. [0028] [0032] [0033] [0033] If the content of the image captured on the right is confirmed as a landmark guiding feature, then step S35 is performed. 535 ‘The matching module determines whether the landmark guiding feature in the image image matches the landmark data to be traveled by the planning path listed in the landmark list. If the matching feature matches, step S36 is performed. 536: The comparison module sends a first guiding signal to the navigation interface, and the navigation interface prompts the planning path according to the first guiding signal to include information related to the mantle data. Thereby, the user can receive the landmark data guidance of the turning point provided by the navigation system, and the landmark guiding feature of the turning point can be clearly identified by the image recognition unit in the comparison module, so that the user can Clearly seeing the landmark guiding features and hearing the clear guidance of the navigation system will be able to know the direction of the travel in the -T word, the intersection or the complex, and then travel the route to be driven. However, if the comparison module judges that the features do not match, step S37 is performed. 537: The comparison module sends a second guiding signal to the navigation interface navigation interface to indicate the planning path according to the second guiding signal without including information related to the landmark information.
