First embodiment
Fig. 2 is a basic flowchart of a method for recording a motion trail provided in this embodiment, where the method for recording a motion trail includes:
s201, acquiring a matrix block of the current loading map, and storing according to a unique path.
In the step, all matrix blocks of the current loading map are acquired, each matrix block is stored according to a unique path, the matrix blocks comprise matrix pictures and matrix coordinates, and the matrix pictures are obtained by dividing the loading map according to preset rules.
S202, recording motion trail points and storing the motion trail points into a cache queue.
In the step, track points generated in the motion process are recorded, and the track points are stored in a buffer queue, wherein the motion track points are positioning points of a user recorded at intervals in the motion process.
S203, drawing the track points in the buffer queue into corresponding matrix pictures and connecting the track points in sequence when the preset conditions are met.
In the step, when a preset condition is met, drawing track points stored in a cache queue on a corresponding matrix picture; and drawing the track points stored in the buffer queue into corresponding matrix pictures when the preset condition is a trigger condition and the preset condition is met, sequentially connecting the track points to form a motion track, and finally storing the motion track in a picture form.
S204, updating the drawn matrix picture to the corresponding storage path.
In this embodiment, step S201, obtain a matrix block of a current loading map, and store the matrix block according to a unique path; in the step, all matrix blocks of the current loading map are obtained, and each matrix block is stored according to a unique path; in the embodiment of the invention, the matrix pictures and the matrix coordinates are connected together to form a matrix block, the matrix block is stored in a storage process, and the matrix block is stored in a storage process according to a unique path to avoid the problem of map display errors caused by the fact that a plurality of matrix pictures appear in the same storage path.
In this embodiment, when dividing the picture into matrix blocks in step S201, the matrix blocks need to be stored according to a unique path, and the storing process includes: acquiring matrix coordinates of a matrix block in a current loading map, and establishing a unique storage path for the matrix block by utilizing the matrix coordinates; storing the matrix blocks into storage paths corresponding to the matrix coordinates; and establishing a matrix storage catalog according to the matrix coordinates and the corresponding storage paths. When the map is divided, the map is divided in a matrix block mode, one matrix block comprises matrix coordinates and matrix pictures of the matrix block, the coordinates of the matrix only exist in one map, and only one corresponding matrix picture exists under the matrix coordinates, so that a storage path can be established according to the matrix coordinates when a unique storage path of the matrix block is determined; after a unique storage path is established, storing a matrix picture and a matrix coordinate corresponding to the matrix block under the path, and jointly storing the matrix coordinate and the corresponding matrix picture under the same path has the advantages that the matrix picture can be checked with the coordinate of the picture when the matrix picture is required to be displayed, and whether the matrix picture required by the current coordinate is required or not is judged; after the unique storage path of the matrix block is established according to the matrix coordinates, a matrix storage directory is established according to the coordinates of the matrix and the corresponding storage paths, and the matrix storage directory is established so as to be convenient for quickly finding the storage path of the needed matrix block through the matrix coordinates.
In this embodiment, after the map currently loaded is divided into matrix blocks and stored, the stored matrix blocks need to be displayed according to display requirements. Therefore, before the motion trail point is recorded and stored in the buffer queue in step S202, the method further includes: determining the matrix coordinates of a matrix picture to be displayed currently according to the size of the screen display content; finding a corresponding storage path from the matrix storage directory according to the matrix coordinates, and reading out a matrix picture from the corresponding storage path; and displaying the read matrix picture on the corresponding matrix coordinate to form a map.
When the currently displayed map is zoomed or moved, the matrix picture contained in the map is obtained again; when a corresponding storage path cannot be found from the matrix storage directory according to the matrix coordinates, inquiring a corresponding matrix picture from the database according to the matrix coordinates, and taking out the matrix picture according to the specification of the same size as other matrix pictures to form a map together with other matrix pictures; and simultaneously, storing the matrix picture taken out of the database and the corresponding matrix coordinates in a cache.
In this embodiment, when the map is moved or scaled, the map content needs to be displayed newly, so that coordinate information on the map needs to be acquired again, the map information is then the matrix coordinates, the storage path of the corresponding matrix picture is queried from the matrix catalog according to the acquired matrix coordinates, the matrix picture under the corresponding storage path is read according to the storage path, when the matrix picture is read, the acquired matrix coordinates and the matrix coordinates stored under the storage path can be compared for two times to confirm whether the matrix picture is the required matrix picture, after confirming, the matrix picture stored under the path is read out, and the matrix picture is displayed on the corresponding matrix coordinate to form the map together with other matrix pictures.
In other embodiments, when a corresponding storage path cannot be found in the matrix memory directory according to the acquired matrix coordinates, that is, when a matrix picture corresponding to the matrix coordinates is not stored locally, the corresponding matrix picture is queried from the database according to the acquired matrix coordinates, and the corresponding matrix picture is read from the database according to the specification of the same size of other stored matrix pictures, and is displayed on the corresponding matrix coordinates, and forms a map together with other matrix pictures, and meanwhile, the matrix picture read from the database and the corresponding matrix coordinates are stored in the cache for temporary storage.
In this embodiment, when the buffer queue is full, if the preset condition is not satisfied yet, the trace point stored in the queue is stored in the database, and the buffer queue is emptied; drawing track points stored in a database and a cache queue into corresponding matrix pictures until a preset condition is met, and sequentially connecting the track points to form a motion track; updating the drawn matrix picture to the corresponding storage path, and simultaneously emptying the buffer queue. In the embodiment of the invention, the motion trail is initially recorded in the buffer queue, and the trail points stored in the buffer queue are drawn into the corresponding matrix pictures only when the preset condition is met, so that in some cases, when the buffer queue is full, the preset condition is not met yet, and in order to avoid the problem of emptying the queue or moving the trail points caused by memory overflow, when the buffer queue is full, the trail points stored in the buffer queue are transferred into data for storage.
In this embodiment, step S203, when a preset condition is met, the track points in the buffer queue are drawn on the corresponding matrix pictures. In the embodiment of the invention, the preset conditions are not limited, and can be reasonably changed according to actual situations in the actual application process, for example, the preset conditions can be set when the time reaches the preset time, the movement of the map can be set as the preset conditions, the scaling of the map can be set as the preset conditions, the preset conditions can also be set when the buffer queue is full, and the like.
For convenience of description of the present embodiment, the present embodiment is described assuming that the preset condition is map refresh, and map refresh includes map movement and scaling of the map as the preset condition. Under the preset condition, executing step S203, satisfying the preset condition, drawing the track points in the buffer queue into the corresponding matrix pictures, and sequentially connecting the track points to form a motion track; while also encompassing several different situations, some of which are described below with respect to common situations.
First case: when the map is refreshed, when matrix pictures contained in the formed map do not contain matrix pictures taken out of the database, track points stored in the buffer queue are drawn into corresponding matrix pictures, and the track points are sequentially connected to form a motion track; and updating the drawn matrix picture to the corresponding storage path, and simultaneously emptying the buffer queue.
Second case: when the map is refreshed, when matrix pictures which are contained in the map are obtained again and contain matrix pictures which are taken out of the database, track points stored in the buffer queue are drawn into the matrix pictures which are stored in the buffer and taken out of the database, and the track points are connected in sequence to form a motion track; establishing a new storage path through the corresponding matrix coordinates, storing the matrix picture after drawing the track points under the newly established storage path, and simultaneously clearing a cache queue and a matrix picture cache; and updating the matrix storage catalogue according to the corresponding coordinate points and the corresponding storage paths. In this case, since the matrix picture read from the database is not directly set up a storage path, but is temporarily stored in the buffer memory, only when it is determined that the track point has been drawn into the matrix picture, a corresponding storage path is set up for the matrix picture, so that the problems of speed reduction and excessive memory occupation caused by storing the matrix can be reduced.
The beneficial effects of this embodiment are:
