To make the objects, technical solutions and advantages of the present application more clear, embodiments of the present application will be described in further detail below with reference to the accompanying drawings.
In the prior art, an application takes a current time period as a theme switching basis, that is, a developer sets a theme switching time point for the application, and the application is applied to terminal devices such as a vehicle-mounted device and a handheld device. For example, taking an in-vehicle map as an example, a developer considers that the illumination intensity of the environment in which the vehicle is located is strong in the daytime during a time period from sunrise to sunset, and defaults to display a daytime theme in order to prevent a user from blinding the map, and that the illumination intensity of the environment in which the vehicle is located is weak in the night period from sunset to sunrise, and defaults to display a nighttime theme in order to prevent the user from glaring when looking at the map. Specifically, the sunset time and the sunrise time are respectively used as theme switching time points, and the daytime theme is switched to the display of the night theme at the sunset time, and the night theme is switched to the display of the day theme at the sunrise time. However, for the case that the day weather is cloudy (although the day is daytime but the illumination intensity is weak) or the case that the day is in a parking lot (although the night is night but the illumination intensity is strong), it is obvious that the theme displayed in the corresponding case by the switching scheme is not matched with the illumination intensity of the environment where the switching scheme is located, and the use experience of the user is reduced. In view of the above problem, an embodiment of the present application provides a theme switching method for an application, and the method will be described in detail below with reference to the accompanying drawings.
Fig. 1 is a schematic flowchart of a theme switching method for an application provided in an embodiment of the present application, where an execution main body of the method may be an application, and as shown in fig. 1, the method may include:
step S101, displaying a first theme of the application program.
The application program can be preset with a plurality of themes with different display brightness for switching use. For example, as shown in fig. 2a and 2b, fig. 2a is a schematic diagram of a vehicle-mounted map displaying a day theme, and fig. 2b is a schematic diagram of the vehicle-mounted map displaying a night theme.
Step S102, responding to a theme switching instruction, and switching to a second theme of the display application program, wherein the theme switching instruction is generated when the illumination intensity and the scene type of the current environment meet preset conditions, and the display brightness of the first theme is different from that of the second theme.
The scene types may include scene types divided based on various different weather conditions, urban or outdoor environments, and various visibility, for example, there may be a cloudy scene type, a parking lot scene type, and the like. It can be understood that a plurality of scene types can be preset according to requirements and actual conditions.
Specifically, the application program judges whether the illumination intensity and the scene type of the current environment meet preset conditions, if so, a corresponding theme switching instruction is generated, meanwhile, a second theme more suitable for the illumination intensity and the scene type of the current environment is determined according to the illumination intensity and the scene type of the current environment, and then the application program responds to the theme switching instruction and switches from the displayed first theme to the displayed second theme.
According to the scheme, the application program generates the theme switching instruction when the illumination intensity and the scene type of the current environment meet the preset conditions, so that the application program responds to the theme switching instruction and switches from the first theme to the second theme which is more suitable for the illumination intensity and the scene type of the current environment.
In an optional embodiment of the present application, the method may further comprise:
receiving automatic switching operation of a theme sent by a user;
responding to automatic theme switching operation, and acquiring at least two frames of environment images of the environment at intervals of first preset time;
and acquiring the illumination intensity and the scene type of the current environment based on at least two frames of environment images of the current environment.
The theme automatic switching operation may be an instruction for automatically switching themes, which is sent to the application program by the user, and the application program may switch themes according to the theme switching scheme provided in the present application after receiving the instruction. In practical applications, as shown in fig. 3, a corresponding theme automatic switching button 301 may be set on a setting page of an application program, and a user may issue an instruction to automatically switch a theme to the application program by triggering the button, and at the same time, the user may also issue an instruction to continuously display the first theme or the second theme to the application program by triggering a first theme (for example, a day theme) button 302 or a second theme (for example, a night theme) button 303.
Wherein the application program can acquire at least two frames of environment images from the corresponding image acquisition devices. The image acquisition equipment needs to be capable of shooting color images with enough definition, and for vehicle-mounted application programs, the image acquisition equipment can be a vehicle event data recorder camera positioned below the middle top end of a windshield, can also be a panoramic (360-degree view) camera positioned around a vehicle body, and the shooting content is environment information and the like near the vehicle.
Specifically, after receiving an instruction for automatically switching themes, the application program needs to acquire the illumination intensity and the scene type of the environment where the application program is located. The first preset duration can be set according to actual requirements, and can also be set according to the frame rate of the image acquisition device. That is, the program obtains the environment image of the environment without interruption, that is, at least two frames of images of the environment are obtained at each image obtaining time, and two adjacent image obtaining times are separated by a first preset time.
In an optional embodiment of the present application, the determining that the illumination intensity and the scene type of the current environment satisfy the preset condition includes:
comparing the illumination intensity and the scene type of the current environment with the illumination intensity and the scene type of the environment at the last image acquisition moment respectively to obtain a comparison result;
and if the comparison result indicates that at least one of the illumination intensity of the current environment or the scene type is changed compared with the last image acquisition time, determining that the illumination intensity of the current environment and the scene type meet preset conditions.
Specifically, at least two frames of environment images of the current environment are acquired at the current image acquisition time, the illumination intensity and the scene type of the current environment are acquired based on the at least two frames of environment images, and the illumination intensity and the scene type are compared with the illumination intensity and the scene type of the environment at the previous image acquisition time. If the illumination intensity corresponding to the current image acquisition time is changed, or the scene type is changed, or both the illumination intensity and the scene type are changed relative to the previous image acquisition time, the preset condition is met; and if the illumination intensity and the scene type corresponding to the current image acquisition moment are not changed relative to the last image acquisition moment, the preset condition is not met. If the preset condition is met, switching to displaying the second theme, and if the preset condition is not met, continuing to display the first theme.
It should be noted that in the above-mentioned scheme, the illumination intensity is changed, specifically, the illumination intensity is changed to a certain degree, for example, the illumination intensity of the current environment is 3 levels (assuming a total of 10 levels), if the illumination intensity corresponding to the previous image acquisition time is 5 levels or 1 levels, that is, the difference between the current environment and the previous image acquisition time is 2 levels, it is determined that the situation satisfies the preset condition, if the illumination intensity corresponding to the previous image acquisition time is 4 levels or 2 levels, that is, the difference between the current environment and the previous image acquisition time is 1 level, it is determined that the difference between the current environment and the previous image acquisition time is not large, in order to avoid too frequent theme switching, it is determined that the situation does not satisfy the preset condition, that is, in other words, the preset condition is satisfied only if the illumination intensity change reaches 2 levels. It is understood that the degree of the change required to determine whether the debate occurs may be set, for example, according to the preference or actual requirement of the user, which is not limited in the present application.
In an optional embodiment of the present application, in response to the theme switching instruction, switching to the second theme of the display application includes:
and responding to the theme switching instruction, and switching to display the second theme after continuously displaying the first theme for a second preset time.
Specifically, after the application program obtains the theme switching instruction, in order to provide an adaptation time for the eyes of the user, the application program may continue to display the first theme for a second preset time period, and then switch to display the second theme. Furthermore, the display of the first theme for the second preset time can be continued, and then the second theme is smoothly switched to be displayed, that is, the display brightness of the theme is slowly changed during the process of switching from the first theme to the second theme, so as to give the eyes of the user another adaptive time.
For example, for a vehicle-mounted map, a user drives into a garage with better illumination at night, and then switches to display a corresponding brighter theme (or slowly switches to a corresponding brighter theme) after continuing to display a period of darker theme in order to give the user a suitable time for the eyes of the user.
Further, the second preset time is shorter than the first preset time.
Specifically, the second preset time length is shorter than the first preset time length, so that the theme switching is completed before the next theme switching comes.
In an optional embodiment of the present application, the obtaining a scene type of a current environment based on at least two frames of environment images of the current environment includes:
inputting at least two frames of environment images of the current environment into a preset classification network model, and outputting at least one corresponding initial scene type;
voting is carried out based on at least one initial scene type to obtain a corrected scene type, and the corrected scene type is verified;
and if the corrected scene type passes the verification, taking the corrected scene type as the scene type of the current environment.
The input of the preset classification network model is an environment image, and the output is a corresponding scene type, such as cloudy days, rainy days, parking lots, tunnels and the like.
In one or more embodiments, the preset classification network model selects a lightweight model according to a specific scene applied to a vehicle-mounted end or a mobile end, and in the model, the calculation amount is reduced by technologies such as deep separable convolution and Channel Shuffle. In one or more embodiments, acceleration of certain hardware platforms is achieved through model pruning, quantization, and other methods in combination with ARM assembly.
In one or more embodiments, the specific structure of the preset classification network model is as follows: the MobileNet series or ShuffleNet and the like are selected as the front end of the model, and YOLO (young Only Look Once convolution operation) or full convolution layer with jump connection is selected as the back end of the model. And inputting the environment image into a front-end network for processing, and outputting the initial scene type through back-end operation. Through the preset classification network model structure, the accuracy of a processing result can be improved while the calculation amount is reduced.
In one or more embodiments, the output of the preset classification network model may specifically be a certain preset scene type, or may also be probability values corresponding to multiple preset scene types.
In one or more embodiments, a plurality of frames of environment images of the current environment are input into a preset classification network model, a plurality of scene types are output, the scene types are voted, the scene type with the highest vote is used as a corrected scene type, then the corrected scene type is verified, if the scene type passes the verification, the corrected scene type is used as the scene type of the current environment, and if the scene type does not pass the verification, the corrected scene type is discarded.
In one or more embodiments, the voting scheme may adopt a minority-compliant majority rule, that is, a result with the highest occurrence number in a plurality of results output by the preset classification network model is used as a result with the highest vote, in other words, a scene type with the highest occurrence number is used as a modified scene. Furthermore, in the process of voting, each result can be given a corresponding weight, and then the weighting times of each result can be calculated. It is understood that, when assigning the weight corresponding to each result, the acquiring time of the environment image corresponding to each result may be considered, specifically, the weight value assigned to the result corresponding to the environment image whose acquiring time is closer to the current time is larger, and if each result is a probability value, the weight value assigned to the result is larger as the probability value is larger.
In one or more embodiments, further checking the modified scene type includes:
acquiring position information of a current environment;
determining a scene type set in a preset geographic range based on the position information;
and if the scene type set contains the corrected scene type, determining that the corrected scene type passes the check, otherwise, determining that the corrected scene type fails the check.
Specifically, the corrected scene type is verified through other data sources, and the corrected scene type can be verified through the position information of the current environment, specifically, firstly, all scene types in the peripheral preset geographic range of the current environment are obtained through the position information (for example, GPS position information) of the current environment in combination with a map, and a scene type set is formed. And then, judging whether the acquired scene type set contains the corrected scene type, if so, checking to pass, otherwise, checking not to pass.
In one or more embodiments, the scene type result may be corrected in conjunction with information about the current environment location, weather, etc. For example, according to the position information of the current environment and the weather condition of the area corresponding to the position information, if the current weather is sunny and the illumination condition is good, it is determined that a tunnel exists in the corresponding area, and the modified scene type determined by the method is a cloudy scene, the modified scene is checked by the method and is not passed, and the current environment is determined to be possibly in the tunnel by comprehensive judgment, so that the current scene type can be corrected to be tunnel driving, and the theme switching operation of the subsequent application program is completed. By the method, the accuracy of scene recognition in specific occasions (such as tunnels) can be further overcome, and the user experience is further improved.
In an optional embodiment of the present application, the obtaining the illumination intensity of the current environment based on at least two frames of environment images of the current environment includes:
inputting at least two frames of environment images of the current environment into a preset regression network model, and outputting at least one corresponding illumination intensity;
acquiring average illumination intensity of at least one illumination intensity, and checking the average illumination intensity;
and if the average illumination intensity passes the verification, taking the average illumination intensity as the illumination intensity of the current environment.
The input of the preset regression network model is an environment image, the output of the preset regression network model is corresponding illumination intensity, the illumination intensity can be preset to be a certain value from 1 to 100, and the preset classification network model can be obtained through training of a sample image marked with the illumination intensity in advance. The regression model is preset as a regressor with the image as input. In one or more embodiments, the output of the regressor has only one-dimensional vector, and the front end of the preset regression model is similar to the preset classification network model, for example, MobileNet is adopted, so as to reduce the amount of calculation and improve the processing efficiency.
Specifically, inputting a plurality of frames of environment images of the current environment into a preset regression network model, outputting a plurality of illumination intensities, calculating average illumination intensities corresponding to the plurality of illumination intensities, then verifying the average illumination intensities, taking the average illumination intensities as the scene type of the current environment if the average illumination intensities pass the verification, and discarding the average illumination intensities if the average illumination intensities do not pass the verification.
Further, the average illumination intensity is checked, including:
acquiring an illumination intensity measured value of an illumination sensor under the current environment;
acquiring a corresponding illumination intensity range based on the illumination intensity measured value;
if the illumination intensity range contains the average illumination intensity, the average illumination intensity is checked to be passed, otherwise, the average illumination intensity is checked not to be passed.
Specifically, the average illumination intensity is verified through other data sources, and the average illumination intensity can be verified through the illumination intensity measurement measured by the illumination sensor. And then, judging whether the acquired illumination intensity range contains the average illumination intensity, if so, passing the verification, otherwise, failing to pass the verification.
It should be noted that, in the case that the average illumination intensity check is not passed, the illumination intensity provided by other data sources such as the illumination sensor may be regarded as a reference, and the current illumination intensity is corrected, for example, the calculation result is adjusted according to a difference between the illumination intensity provided by other data sources such as the illumination sensor and the calculation result, and the adjusted result is taken as the current illumination intensity, so as to complete the theme switching operation of the subsequent application program.
For a vehicle-mounted map, implementation of the theme switching scheme provided in the embodiment of the present application depends on the architecture shown in fig. 4a, and at each image acquisition time, the vehicle-mounted camera 401 acquires multiple frames of environment images and sends the acquired environment images to the vehicle-mounted application program. In the in-vehicle application, the scene analysis unit 402 and the illumination analysis unit 403 respectively analyze the input environment image to obtain a corresponding scene type and illumination intensity, and send the scene type and illumination intensity to the instruction generation unit 404. The instruction generating unit 404 analyzes whether the received scene type and the received illumination intensity satisfy a preset condition, generates a corresponding theme switching instruction if the scene type and the illumination intensity satisfy the preset condition, and sends the theme switching instruction to the instruction executing unit 405. The instruction execution unit 405 switches from displaying the second theme to the first theme based on the received theme switching instruction. Meanwhile, in the case that it is determined that the preset condition is satisfied, the instruction generating unit 404 further determines a corresponding second theme based on the received scene type and the illumination intensity, and sends the second theme to the instruction executing module 405. Fig. 4b is a schematic diagram of an implementation process of theme switching of the vehicle-mounted map in this example, where the left side in the diagram is a flow of a scene type determination process, and the right side in the diagram is a flow of an illumination intensity determination process.

Step S402, the scene analysis unit and the illumination analysis unit respectively analyze the input environment image to obtain an analysis result.
The process of the left-side scene type determination process comprises the following steps:
s4021, inputting multi-frame environment images into a preset classification network model, and outputting corresponding multi-frame scene type results;
step S4022, voting based on the multi-frame scene type to obtain a corrected scene type;
step S4023, checking the corrected scene type based on the position information of the current environment to obtain a scene analysis result.
The right side illumination intensity determination process comprises the following steps:
s4021', inputting a plurality of frames of environment images into a preset regression network model, and outputting corresponding multi-frame illumination intensity results;
