Description
本發明係關於一種導航的方法、電腦程式及電腦可讀取媒體，特別係指一種在實境影像中執行導航的方法、程式及可讀取媒體。 The present invention relates to a navigation method, a computer program, and a computer-readable medium, and in particular, to a method, program, and computer-readable medium for performing navigation in a real image.
當人的腦部神經發展產生障礙時，或是腦部退化之後，例如自閉症或失智症的患者，常會有迷路的情況。為了避免患者迷路，最直接的方式是讓患者攜帶繪製好的地圖，並在地圖上標示出醒目的地標，以讓患者找到回家或前往特定地點的路。 When people's brain nerve development is hindered, or after brain degeneration, such as patients with autism or dementia, they often get lost. In order to prevent the patient from getting lost, the most direct way is to have the patient carry a drawn map with prominent landmarks marked on the map so that the patient can find the way home or to a specific place.
一般的地圖無法立即顯示患者的所在位置，對於患者來說可能仍較難以判讀，因此患者的家人或醫護人員可以讓患者攜帶可以實時導航的裝置，具體例如中國專利公告號第CN 102121831 B號提供的一種實時街景導航方法及設備，主要是在行駛過程中終端的採集裝置實時採集所處位置的實時街景並在顯示屏上顯示，在導航路線信息的各導航點中，實時確定與接收到的GPS信息中地理座標相匹配的當前導航點，並在顯示屏上顯示的導航路線中顯示當前導航點。 General maps cannot immediately display the patient's location, and it may still be difficult for the patient to interpret. Therefore, the patient's family or medical staff can allow the patient to carry a device that can navigate in real time. For example, China Patent Publication No. CN 102121831 B provides A real-time street view navigation method and device, mainly in the process of driving, the collection device of the terminal collects the real-time street view of the location in real time and displays it on the display screen, and in each navigation point of the navigation route information, the real-time determination and reception are carried out. The current navigation point that matches the geographic coordinates in the GPS information, and displays the current navigation point in the navigation route displayed on the display.
除了前述專利案的方式，Google於2018年也在Google Maps應用程式中推出了AR實景導航功能，用戶選擇「Live View」模式後，會切換至手機當前鏡頭拍攝的實景即時畫面，並且會顯示指示方向的AR標誌。 In addition to the method of the aforementioned patent case, Google also launched the AR real-time navigation function in the Google Maps application in 2018. After the user selects the "Live View" mode, it will switch to the real-time real-time image captured by the current lens of the mobile phone, and an indicator will be displayed. AR sign for directions.
然而，無論是前述專利案，還是Google Maps的「Live View」模式，都無法自由設定導航的路線中要經過哪些場所，使用上仍十分不便。 However, neither the aforementioned patent case nor the "Live View" mode of Google Maps can freely set which places to pass through in the navigation route, which is still very inconvenient to use.
