(1)可簡化導航畫面的複雜度，使得使用者更容易判斷目前行駛狀況。 (1) The complexity of the navigation screen can be simplified, making it easier for the user to judge the current driving situation.
(2)可規劃出使用者較熟悉的導航路徑，增加行駛時的安全感。 (2) The navigation path familiar to the user can be planned to increase the sense of security during driving.
請參閱第1圖，其係為本發明之可顯示參考點之導航系統之方塊圖。圖中，可顯示參考點之導航系統1包含一儲存模組11、一定位模組12、一輸入模組13、一導航模組14及一顯示模組15。儲存模組11係儲存複數個電子地圖111及至少一參考點112。其中，參考點112係為使用者所熟悉的地點，使用者可使用輸入模組13自行輸入，或是從電子地圖中的景點(POI)選出作為參考點。 Please refer to FIG. 1 , which is a block diagram of a navigation system capable of displaying a reference point according to the present invention. In the figure, the navigation system 1 that can display the reference point includes a storage module 11, a positioning module 12, an input module 13, a navigation module 14, and a display module 15. The storage module 11 stores a plurality of electronic maps 111 and at least one reference point 112. The reference point 112 is a location familiar to the user, and the user can input it by using the input module 13 or select a point of view (POI) in the electronic map as a reference point.
定位模組12係提供一當前位置121。定位模組12較佳的是包含一全球定位系統(GPS)模組、一電子羅盤或是一陀螺儀，而當前位置121係為包含經緯度之座標資料。輸入模組13係接收一目的地131。輸入模組13較佳的是包含一鍵盤或是一觸控模組。導航模組14係根據從儲存模組11中選擇複數個電子地圖111之其一，例如選出包含當前位置121及目的地131之間的電子地圖111。接著導航模組14根據所選電子地圖111規劃出一可到達此目的地131之導航路徑141，並根據導航路徑141及當前位置121產生一導航訊息142，例如”前方路口請左轉”或是”此路段速限為時速50公里”等等。導航訊息142可包含訊息影像或訊息語音。其中，由於參考點112是使用者所熟悉的地點，所以參考點112視需要可設定具有較高的路徑規劃權重，使得導航模組14規劃出接近參考點112的導航路徑141。如此，可增加使用者行駛導航路徑141的安全感。 The positioning module 12 provides a current position 121. The positioning module 12 preferably includes a global positioning system (GPS) module, an electronic compass or a gyroscope, and the current position 121 is a coordinate data including latitude and longitude. The input module 13 receives a destination 131. The input module 13 preferably includes a keyboard or a touch module. The navigation module 14 selects, for example, one of the plurality of electronic maps 111 from the storage module 11, for example, an electronic map 111 including the current location 121 and the destination 131. The navigation module 14 then plans a navigation path 141 that can reach the destination 131 according to the selected electronic map 111, and generates a navigation message 142 according to the navigation path 141 and the current location 121, for example, "turn left at the front intersection" or "The speed limit of this section is 50 kilometers per hour" and so on. The navigation message 142 can include a message image or a message voice. Wherein, since the reference point 112 is a location familiar to the user, the reference point 112 can be set to have a higher path planning weight as needed, so that the navigation module 14 plans the navigation path 141 close to the reference point 112. In this way, the sense of security of the user driving the navigation path 141 can be increased.
顯示模組15係顯示所選電子地圖111、導航路徑141及參考點112，且導航路徑141及參考點112的顯示方式係比所選電子地圖111的顯示方式更為顯著。 The display module 15 displays the selected electronic map 111, the navigation path 141, and the reference point 112, and the navigation path 141 and the reference point 112 are displayed in a more prominent manner than the selected electronic map 111.
在實施上，顯示模組15較佳的是以明顯顯示(highlight)的方式來顯示導航路徑141及參考點112，例如以較明顯的顏色，或是以尺寸較大的圖案顯示導航路徑141及參考點112；亦或顯示模組15較佳的是淡化顯示所選電子地圖111，例如以較淡的顏色顯示所選電子地圖111，如第2圖所示，導航路徑141及複數個參考點112以較大尺寸來明顯地顯示；亦或顯示模組15較佳的是不顯示所選電子地圖111，僅顯示導航路徑141及參考點112，如第3圖。藉由上述明顯顯示(highlight)的方式，讓使用者一看到螢幕便可觀看到導航路徑141與子幾熟悉的參考點112的相對位置，此外，參考點112附近的一地圖資料視需要亦可以明顯顯示(highlight)的方式來顯示，例如將電子地圖淡化顯示，而將參考點112及其在預設距離內的街道明顯顯示，如第4圖所示。 In practice, the display module 15 preferably displays the navigation path 141 and the reference point 112 in a highlight manner, for example, in a more obvious color, or in a larger format, the navigation path 141 and Reference point 112; or display module 15 preferably fades the selected electronic map 111, for example, displays the selected electronic map 111 in a lighter color, as shown in FIG. 2, the navigation path 141 and the plurality of reference points 112 is displayed in a larger size; or the display module 15 preferably does not display the selected electronic map 111, only the navigation path 141 and the reference point 112 are displayed, as shown in FIG. By means of the above-mentioned highlight, the user can see the relative position of the navigation path 141 and the familiar reference points 112 as soon as the user sees the screen. In addition, a map data near the reference point 112 is also needed. The display can be displayed in a highlight manner, such as dimming the electronic map display, and the reference point 112 and its streets within a preset distance are clearly displayed, as shown in FIG.
此外，當參考點112的數目過多時，若是顯示模組15顯示全部參考點112，則導航畫面可能會過於複雜而讓使用者困擾。因此，當參考點112的數目超過一第一門檻值113時，則顯示模組15係根據導航路徑141將所選電子地圖111分為複數個顯示區域，例如將導航路徑141有經過的電子地圖111橫向切分或是縱向切分。而顯示模組15於每一顯示區域顯示出數目低於一第二門檻值114的參考點。其中，顯示模組15係優先顯示較接近導航路徑15之參考點112。如第5圖所示，圓圈501係表示的是未顯示的參考點，而實點502係表示有顯示的參考點。由於參考點112 的數目有30個，超過第一門檻值113，因此根據導航路徑141將電子地圖111分為4個顯示區域51~54，且每一區域係顯示4個較接近導航路徑15之參考點。如此，可適度地簡化導航畫面的複雜度，又可讓使用者行經導航路徑141時可根據畫面上的參考點112來確認行駛方向是否正確。此外，當導航路徑的長度過長時，例如超過一預設值，亦根據上述方式顯示電子地圖及參考點。 In addition, when the number of reference points 112 is too large, if the display module 15 displays all the reference points 112, the navigation screen may be too complicated to be bothered by the user. Therefore, when the number of reference points 112 exceeds a first threshold value 113, the display module 15 divides the selected electronic map 111 into a plurality of display areas according to the navigation path 141, for example, an electronic map through which the navigation path 141 passes. 111 transverse split or longitudinal split. The display module 15 displays a reference point whose number is lower than a second threshold value 114 in each display area. The display module 15 preferentially displays the reference point 112 that is closer to the navigation path 15 . As shown in Fig. 5, circle 501 represents a reference point that is not shown, and solid point 502 represents a reference point that is displayed. Due to reference point 112 There are 30 numbers, which exceed the first threshold 113. Therefore, the electronic map 111 is divided into four display areas 51-54 according to the navigation path 141, and each area displays four reference points that are closer to the navigation path 15. In this way, the complexity of the navigation screen can be simplified moderately, and the user can confirm whether the driving direction is correct according to the reference point 112 on the screen when the user navigates through the navigation path 141. In addition, when the length of the navigation path is too long, for example, exceeding a preset value, the electronic map and the reference point are also displayed according to the above manner.
其中，若導航模組14判斷當前位置121已經接近目的地131時，可觸發顯示模組15僅顯示目的地131附近的地圖，並且顯示出所有的參考點，顯示畫面係從第5圖轉變為第6圖，讓使用者可觀看到較詳細的資訊，以順利到達目的地。 If the navigation module 14 determines that the current location 121 has approached the destination 131, the display module 15 can be triggered to display only the map near the destination 131, and all the reference points are displayed, and the display screen is changed from the fifth image to the Figure 6 allows the user to view more detailed information to reach the destination smoothly.
請參閱第7圖，其係為本發明之導航方法之實施例之步驟流程圖。圖中，導航方法包含下列步驟，由開始展開。在步驟61設定至少一參考點及一目的地。此參考點係為使用者所熟悉的地點。接著，在步驟62根據一電子地圖規劃一可到達此目的地之導航路徑。其中，參考點視需要可設定具有較高的路徑規劃權重，使得規劃出的的導航路徑係接近參考點，以增加使用者行駛導航路徑的安全感。 Please refer to FIG. 7, which is a flow chart of steps of an embodiment of the navigation method of the present invention. In the figure, the navigation method consists of the following steps, starting with the expansion. At step 61, at least one reference point and a destination are set. This reference point is a location familiar to the user. Next, at step 62, a navigation path that can reach the destination is planned based on an electronic map. The reference point may be set to have a higher path planning weight as needed, so that the planned navigation path is close to the reference point to increase the security feeling of the user driving the navigation path.
接著，在步驟63提供一當前位置，例如全球定位系統(GPS)所計算出的具有經緯度之座標資料。接著，在步驟64根據導航路徑及當前位置產生一導航訊息。 Next, at step 63, a current location, such as coordinate data with latitude and longitude calculated by the Global Positioning System (GPS), is provided. Next, at step 64, a navigation message is generated based on the navigation path and the current location.
最後在步驟65，顯示電子地圖、導航路徑及上述參考點 ，且導航路徑及至少一參考點的顯示方式係比電子地圖的顯示方式更為顯著，例如，以明顯顯示(highlight)的方式來顯示導航路徑及參考點；亦或淡化顯示電子地圖，如第2圖所示；亦或不顯示電子地圖，僅顯示導航路徑及參考點，如第3圖所示。接著結束此流程。 Finally, in step 65, the electronic map, the navigation path, and the reference point are displayed. And the display manner of the navigation path and the at least one reference point is more prominent than the display manner of the electronic map, for example, displaying the navigation path and the reference point in a highlight manner; or dimming the display of the electronic map, such as 2); or not showing the electronic map, only the navigation path and reference point are displayed, as shown in Figure 3. Then end this process.
此外，當參考點的數目過多時，若是顯示全部參考點，則導航畫面可能會過於複雜而讓使用者困擾，因此，可在顯示導航畫面之前先減少顯示的參考點，以維持較簡化的導航畫面。請參閱第8圖，其係為本發明之導航方法之參考點顯示之另一實施例之步驟流程圖。圖中，此流程係為上述步驟65之另一實施例，由開始展開。在步驟651判斷參考點的數目是否大於一第一門檻值，若是，則在步驟652根據導航路徑將電子地圖分為複數個顯示區域；若否，表示參考點的數目在接受的範圍內，尚不會造成導航畫面過於複雜，因此執行步驟658顯示導航路徑，接著再執行步驟657。在步驟653確認每一顯示區域內所包含的參考點。在實施上，可將參考點的座標位置與顯示區域的範圍定義座標點逐一比對，以確認每一參考點係落在哪一個顯示區域範圍內。接著，在步驟654分別從每一顯示區域內所包含的參考點中選出數目為第二門檻值，較接近導航路徑的參考點，例如，若是顯示區域內包含的參考點多於4個，則在此顯示區域內選出較接近導航路徑的4個參考點，若是顯示區域內包含的參考點少於或等於4個，則選擇所有參考點。在步驟655，顯示導航路徑及所選之參考點，而其他參考點則隱藏不顯示，如 第5圖所示。在步驟656，判斷當前位置是否已經接近目的地，若是，則在步驟657顯示所有參考點。其中，當判斷當前位置已經接近目的地時，亦可放大(zoom-in)電子地圖，讓使用者可更清楚地觀看目的地附近的地圖及參考點，如第6圖所示。 In addition, when the number of reference points is too large, if all the reference points are displayed, the navigation screen may be too complicated and troublesome for the user. Therefore, the reference point of the display may be reduced before the navigation screen is displayed, so as to maintain a simplified navigation. Picture. Please refer to FIG. 8, which is a flow chart of the steps of another embodiment of the reference point display of the navigation method of the present invention. In the figure, this flow is another embodiment of the above step 65, which is started from the beginning. In step 651, it is determined whether the number of reference points is greater than a first threshold, and if so, the electronic map is divided into a plurality of display areas according to the navigation path in step 652; if not, indicating that the number of reference points is within the accepted range, The navigation screen is not too complicated, so step 658 is executed to display the navigation path, and then step 657 is performed. At step 653, the reference points contained in each display area are confirmed. In practice, the coordinate position of the reference point and the range defining coordinate point of the display area may be aligned one by one to confirm which display area the reference point falls within. Then, in step 654, the number of reference points included in each display area is selected as a second threshold value, which is closer to the reference point of the navigation path. For example, if there are more than four reference points included in the display area, Four reference points closer to the navigation path are selected in the display area, and if the reference points included in the display area are less than or equal to four, all reference points are selected. In step 655, the navigation path and the selected reference point are displayed, while other reference points are hidden and not displayed, such as Figure 5 shows. At step 656, it is determined if the current location is already near the destination, and if so, all reference points are displayed at step 657. Wherein, when it is judged that the current location is close to the destination, the zoom-in electronic map may be zoomed in so that the user can more clearly view the map and the reference point near the destination, as shown in FIG.
以上所述僅為舉例性，而非為限制性者。任何未脫離本發明之精神與範疇，而對其進行之等效修改或變更，均應包含於後附之申請專利範圍中。 The above is intended to be illustrative only and not limiting. Any equivalent modifications or alterations to the spirit and scope of the invention are intended to be included in the scope of the appended claims.
