During actual implementation, the processor of terminal controllably apply electronic map including on the display screen by figure class.
Fig. 3 is the flow chart of image processing method of the embodiment of the present invention based on electronic map, as shown in figure 3, the flow
It can include：
Step 301：After determining programme path on the electronic map, programme path is segmented, draws each point
Section route.
In actual applications, the processor of terminal can determine programme path, and control according to the beginning and end of input
The programme path of above-mentioned record is shown on the electronic map, in order to which user checks.
Here, it is sequentially connected the broken line formed when programme path is considered as first by multiple line segments, Fig. 4 is real for the present invention
The schematic diagram of programme path in example is applied, as shown in figure 4, the starting point of programme path is A, programme path terminal is B, in Fig. 4, planning
Route is made up of 5 line segments, is designated as line segment C, line segment D, line segment E, line segment F and line segment G respectively.
It should be noted that after being segmented to programme path, each length of route on the electronic map that is segmented is
The length corresponding with the engineer's scale of current electronic map；
For electronic map, engineer's scale represents to scheme the physical length of the length line segment corresponding to ground of a upper line segment
The ratio between, its calculation formula can be：The ratio of map range and actual range；Engineer's scale is bigger, and the scope represented by map is smaller,
The content represented in figure is more detailed, and precision is higher；Engineer's scale is smaller, and represented scope is bigger on map, and the content of reflection is got over
Simply, accuracy is lower；In this way, by controlling scaling up chi, it can make electronic map that more detail contents be presented；Instead
It, reduces engineer's scale by controlling, makes electronic map that bigger scope be presented.
Programme path purpose in greater detail is presented in order to reach, the engineer's scale of electronic map with scaling up chi, can be made
More than certain threshold value, in this way, can make electronic map that the more details of programme path be presented.
Exemplarily, after determining programme path on the electronic map, before being segmented to programme path, control adjustment institute
The engineer's scale of electronic map is stated, the engineer's scale of the electronic map is more than the engineer's scale threshold value of setting.
Here engineer's scale threshold value can be pre-set, and when actually implementing, can pass through the user input unit of terminal
The engineer's scale threshold value pre-set to terminal input user.
When actually implementing, after being segmented to programme path, the segmentation route drawn can only include a line
Section, can also include at least two line segments；
For example, for the programme path shown in Fig. 4, in example 1, after by being segmented to programme path,
4 segmentation routes are drawn, are designated as being segmented route 1, segmentation route 2, segmentation route 3 and segmentation route 4 respectively；Wherein, it is segmented road
Line 1 is made up of line segment C and line segment D, and segmentation route 2 is line segment E, and segmentation route 3 is line segment F, and segmentation route 4 is line segment G.
For the programme path shown in Fig. 4, in example 2, the segmentation route drawn can only include shown in Fig. 4
A line segment a part, for example, the line segment 1 in Fig. 4 divides for Part I and Part II, by entering to programme path
After row segmentation, 3 segmentation routes are drawn, are designated as being segmented route 5, segmentation route 6 and segmentation route 7 respectively, wherein segmentation route 5
For line segment C Part I, segmentation route 6 is made up of line segment C Part II and line segment D, and segmentation route 7 is by line segment E, line segment
F and line segment G compositions.
Preferably, it is a line segment in each segmentation route by being drawn after being segmented to programme path, in this way,
It is easy to get the corresponding detailed information near the segmentation route in follow-up shot operation；Such as, for the rule shown in Fig. 4
For drawing route, in example 3, after by being segmented to programme path, 5 segmentation routes are drawn, are designated as being segmented respectively
Route A1, segmentation route A2, segmentation route A3, segmentation route A4 and segmentation route A5, segmentation route A1 is line segment C, is segmented road
Line A2 is line segment D, and segmentation route A3 is line segment E, and segmentation route A4 is line segment F, and segmentation route A5 is line segment G；
For the programme path shown in Fig. 4, in example 4, after by being segmented to programme path, 7 are drawn
Individual segmentation route, segmentation route B 1, segmentation route B 2 are designated as respectively, route B 3, segmentation route B 4 is segmented, is segmented route B 5, divides
Section route B 6 and segmentation route B 7, wherein, segmentation route B 1 and segmentation route B 2 collectively constitute line segment C, and segmentation route B 3 is line
Section D, segmentation route B 4 is line segment E, and segmentation route B 5 and segmentation route B 6 collectively constitute line segment F, and segmentation route B 7 is line segment G.
Step 302：Sectional drawing is carried out to each segmentation route drawn, obtains image corresponding to each segmentation route.
Here it is possible to by each segmentation route drawn be designated as the 1st segmentation route to n-th segmentation route, n be more than
1 natural number, n represent the quantity of segmentation route；In this way, after the 1st segmentation route to n-th of segmentation route is drawn, respectively
Sectional drawing is carried out to the 1st segmentation route to n-th of segmentation route, draws the image of each segmentation routes of n.
Exemplarily, after sectional drawing is carried out to i-th of segmentation route, i-th drawn is segmented image corresponding to route
Including i-th each segmentation route, i takes 1 to n.
In an optional example, the area of image corresponding to each segmentation route drawn is less than setting area
Threshold value, this way it is possible to avoid being truncated to the detailed information that user need not be known, meet actual demand；When actually implementing, eventually
The processor at end according to the length of setting area threshold and each segmentation route, can determine the sectional drawing area of each segmentation route
Domain.
When actually implementing, the processor of terminal can obtain length and the position of each segmentation route, control generation pin
To the screenshot area of corresponding segments route, so as to which the screenshot area based on generation carries out sectional drawing, to draw corresponding segments route pair
The image answered.
Step 303：According to the order of predetermined each segmentation route, by image corresponding to each segmentation route
Spliced successively, draw spliced image；Wherein, the order of predetermined each segmentation route and the planning
Route is consistent from the order of origin-to-destination, or the order with the programme path from terminal to starting point is consistent.
That is, when carrying out graphic joining, can be carried out successively from the direction of origin-to-destination according to programme path
Splicing, can also be spliced, so, it can be deduced that a width is complete successively according to programme path from terminal to the direction played
Include the image of whole programme path.
It should be noted that when carrying out sectional drawing to each segmentation route, the screenshot area of adjacent two segmentation routes
It there may be lap, that is to say, that image corresponding to the adjacent two segmentation route of above-mentioned record there may be overlapping
Part, now, image mosaic is being carried out, it is necessary to use overlapping merging algorithm for images.
When actually implementing, order that the processor of terminal can be based on programme path from origin-to-destination, or planning road
Order of the line from terminal to starting point, determine the order of each segmentation route；Afterwards, the processor of terminal is according to each segmentation road
The order of line, image corresponding to each segmentation route is spliced successively.
