FIG. 1 illustrates a panoramic image monitoring system start-up procedure prior to optimization;
FIG. 2 is a startup flow of the panoramic image monitoring system after optimization;
fig. 3 is a schematic structural diagram of a computer device in embodiment 2 of the present invention.
Detailed Description
The invention is further illustrated by the following examples:
currently, the panoramic image monitoring system is started up by the following steps:
1. starting a host;
2. starting a panoramic process;
3. loading a drawing window;
4. initializing a camera;
5. acquiring a camera version number;
6. loading a panoramic algorithm library;
7. receiving an activation instruction;
8. and (5) drawing.
The optimization of the invention comprises the following two parts:
1. the acquisition and the transmission of the version number of the camera are not used as a starting necessary flow, and parallel processing is carried out: in order to shorten the drawing time of the cold start system, the version number acquisition is not used as a necessary starting flow, parallel processing is carried out, and the acquisition time point is after the initialization of the camera is completed.
2. Adding parallel flow, and carrying out parallel processing on camera initialization and rendering after drawing: because the time length of the map rendering process is longer than the time length of the initialization of the camera, a start sub-process is added to process the initialization of the camera and the map rendering process in parallel.
Example 1
Taking the improvement of the cold start time of the D511 model panoramic image system as an example, the specific implementation manner is described:
the original starting flow is as follows:
1. the vehicle is started for 0ms;
2. starting a panoramic image monitoring system process;
3. the system runs the signal interaction library and the life cycle until an initialization signal is received; simultaneously, the rendering main thread is started;
4. windows initialization;
5. egl initialization;
7. initializing a camera;
8. acquiring and returning a camera version number;
9. completing initialization of the looking-around ontology SDK algorithm library;
10. sending a standby state to wait for drawing, and realizing output by looking around the rendering;
11. and (5) drawing.
The optimized starting flow is as follows:
1. the vehicle is started for 0ms;
2. starting a panoramic image monitoring system process;
3. the system runs the signal interaction library and the life cycle until an initialization signal is received; simultaneously rendering a main thread starting process and an auxiliary thread starting process in parallel;
4. after the rendering main thread is started, windows initialization and egl initialization are sequentially carried out, the SDK algorithm library of the looking-around ontology is initialized, the standby state is sent to wait for drawing, and the looking-around rendering is realized to output.
5. After the auxiliary thread is started, initializing a camera, acquiring a version number of the camera and returning;
6. and (5) drawing.
The method for optimizing the calling time sequence to shorten the cold start time of the panoramic image system can greatly shorten the cold start time of the panoramic image system. The image can be output after the cold start time is 10s before optimization, and the image display time for the cold start of the system is 7.3s after optimization, so that the system start time requirement is met, and the perception of a user is improved.
