Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail below with reference to the accompanying drawings and examples.
Fig. 1 is a schematic flowchart of a method for locking and unlocking a screen of a touch screen device in an embodiment. As shown in fig. 1, in one embodiment, the present application provides a method for unlocking a lock screen of a touch screen device, including:
s101, when the screen of the equipment is locked, receiving a collection instruction sent by a user through a preset operation of a preset physical key;
in this step, when the device is in the screen locking state, the user can enable the device to send out a collection instruction through the preset operation of the preset physical key. It should be noted that the above process does not conflict with other unlocking methods adopted by the user. In short, the user can directly implement the unlocking method of the present invention through the present step, and can also unlock the lock screen through other conventional manners.
S102, triggering a preset image acquisition device to acquire a target image according to the acquisition instruction, wherein the target image is a real image drawn by a user according to a preset rule;
in this step, the user needs to draw the target image, and the target image is acquired by using a preset image acquisition device by adopting an image recognition technology. The predetermined rule needs to be determined according to image characteristics acquired by an image recognition technology, for example, whether the characteristic attribute of the target image needs to include a color or a background of the image, and the like, and if the characteristic attribute of the target image needs to include the attribute of the color or the background, the content of the image, such as the color or the background, should be rendered during rendering.
S103, comparing the target image with a comparison image prestored in the equipment to obtain similarity;
in the step, the target image and the pre-stored contrast image are compared to obtain the similarity of the target image and the pre-stored contrast image, and a plurality of contrast algorithms of the similarity are available. For example, the similarity calculation result may be a value between 0 and 1, which represents the percentage of the same feature parameter between the target image and the contrast image, and a higher similarity percentage represents that the two images are closer to each other. Conversely, the greater the difference between the two figures. It should be noted that the similarity algorithm provided herein is merely illustrative and not a specific limitation on the similarity algorithm.
And S104, judging whether the similarity meets a preset condition, if so, unlocking successfully, and if not, unlocking unsuccessfully.
In this step, the obtained similarity value needs to be judged, a threshold value can be set under specific preset conditions, and when the similarity value is greater than the threshold value, the target image and the comparison image are considered to be matched with each other, and the unlocking is successful. Otherwise, the unlocking fails. It should be noted that the threshold in this step is only an example of the predetermined condition in this step, and is not specifically limited.
When the device in the embodiment locks the screen, the user may unlock by using a conventional unlocking method, or may unlock by directly using the method of the present application. That is to say, the conventional unlocking method does not conflict with the unlocking method of the present application, but if the conventional unlocking method is found to be impossible due to damage of the touch screen, the unlocking method of the present application may be directly adopted, specifically, a collection instruction may be issued when a predetermined physical key of the device is subjected to a predetermined operation. The preset operation can be an operation of pressing a single preset physical key or an operation of simultaneously pressing a plurality of preset physical keys, then the acquisition instruction triggers the preset image acquisition device to acquire the target image, the target image is compared with a contrast image prestored in the equipment to obtain the similarity of the target image and the contrast image, finally the similarity is judged according to the preset condition, if the preset condition is met, the unlocking is successful, otherwise, the unlocking is failed. By the method, when the touch screen is damaged, a user can bypass the operation on the touch screen and complete screen locking and unlocking through the operation of the preset physical key. The technical problem of when the touch screen of touch screen equipment can't normally work, the user can't smoothly separate the screen, even can't realize separating the screen at all is solved.
In one embodiment, when the device is locked, before the step of receiving a collection instruction sent by a user through a predetermined operation on a preset physical key, the method further includes:
s201, receiving a preset operation of a key of a user, setting the preset physical key, and the preset operation corresponding to the preset physical key, wherein the preset physical key is one or more of physical keys on equipment.
In this embodiment, the preset physical keys may be set through key setting operation of a user, and it should be noted that the preset physical keys may be a plurality of physical keys on the device, and besides the setting of the preset physical keys, a specific operation mode of the preset physical keys, that is, a preset operation, may also be set. For example, the home key and the volume key of the touch-screen mobile phone device are pressed simultaneously, or the home key is pressed first and then the volume key is pressed. Of course, the default setting of the present field can also be used for the preset physical key and the predetermined operation corresponding to the preset physical key.
Fig. 2 is a schematic flowchart of a method for locking and unlocking a screen of a touch screen device in an embodiment. As shown in fig. 2, in one embodiment, the present application provides a method for unlocking a lock screen of a touch screen device, including:
s301, extracting feature points of the target image and the comparison image;
in the step, the feature points of the target image and the comparison image are extracted, and the feature points are extracted for comparison analysis in the subsequent step.
S302, comparing the characteristic points of the target image with the characteristic points of the comparison image to obtain similarity.
In the step, the feature points provided in the previous step are compared to obtain the similarity, the numerical value of the similarity can objectively reflect the matching relation between the target image and the comparison image, actually, the target image can be understood as the password input by the user, the pre-stored comparison image can be understood as the stored unlocking password, and unlocking is realized through the matching of the target image and the comparison image.
The embodiment provides a specific technical means for obtaining the similarity between the target image and the pre-stored contrast image after the feature point comparison, and the adoption of the above method for extracting the feature point can parameterize the comparison of the image, quantify the matching degree between the target image and the pre-stored contrast image, and provide a calculable parameter basis for the subsequent processing.
Fig. 3 is a schematic flowchart illustrating a method for locking and unlocking a screen of a touch screen device in an embodiment. As shown in fig. 3, before the step of extracting the feature points of the target image and the comparison image, the method further includes:
s401, graying the target image;
in this step, the target image is grayed, and the storage space of the grayed target image is greatly compressed.
S402, performing smooth filtering on the grayed target image;
in the step, important information in the target image can be reserved, and in addition, noise points in the target image can be stripped, so that the storage space is further reduced, and noise is reduced.
And S403, denoising the target image after smooth filtering.
In this step, the interference noise points in the target image can be removed.
In the embodiment, a series of processing including graying, smoothing and filtering, and noise point removal is performed on the target image. It is possible to compress the storage space of the target image and remove unnecessary image disturbance noise points.
In one embodiment, the contrast image is a trace map with a connected point background.
In order to accurately perform similarity comparison between the target image and the contrast image in this embodiment, the contrast image may be a trace diagram with a background connected to a point. For example, fig. 4 is an exemplary diagram of drawing a contrast image in one embodiment. As shown in fig. 4, the contrast image is a trace diagram with three rows and three columns of connected dots background, also called a squared figure. When the features are extracted, the feature points of the connection points need to be extracted simultaneously, so that the connection points should be drawn together when the target image is drawn, the number of the feature points is increased, obviously, the greater the number of the feature points, the greater the difficulty of matching between the target image and the contrast image, and the security during unlocking is improved. Since the trajectory graph with the background of the connection points requires the same connection trajectory drawn by the target image and the contrast image on the one hand, and also requires the same positional relationship between the trajectory and the connection points.
Basic principle and working process:
the steps of the present invention are further described below by taking a touch screen mobile phone as an example, and it should be noted that the touch screen mobile phone is only an example for better describing the present invention, and is not a specific limitation of the present invention.
The user can firstly set the preset physical keys of the mobile phone through the key preset operation, and can also set the preset operations of the preset physical keys, such as simultaneously pressing a home key, a power-on key and a volume reduction key. In the above example, the home key, the power-on key, and the volume-down key are preset physical keys, and pressing three preset physical keys simultaneously defines the preset operation.
When the mobile phone enters the screen locking mode, a user can try a traditional screen locking and unlocking mode and can adopt the unlocking method provided by the method. When a user finds that the traditional unlocking method cannot realize unlocking, the unlocking method can be started to realize unlocking, because the traditional unlocking method is implemented through man-machine interaction through a touch screen, and if the touch screen has problems, the traditional screen unlocking operation cannot be realized.
After the user operates the preset physical key of the mobile phone according to the preset operation, the mobile phone can send a collection instruction and trigger an image collection device such as a camera and the like to collect a target image according to the collection instruction, it needs to be pointed out that the target image is an image drawn by the user in reality, and a scanning mode can be used for collecting the target image.
And extracting the feature points of the target image and the comparison image, wherein the feature point extraction is to obtain data of similarity through comparison, and the specific numerical value of the similarity can be calculated after parameterization of the feature points of the target image and the comparison image. The feature point extraction is only one specific example for obtaining the similarity between the target image and the contrast image, that is, the similarity may be obtained in other ways.
And then judging whether the similarity meets a preset condition, wherein the preset condition can be a threshold value of the similarity, if the similarity is greater than the threshold value, the target image is matched with the contrast image, the screen locking and unlocking are successful, otherwise, the unlocking is failed. For further illustration, the similarity may be represented by a value from 0 to 1, and a value closer to 1 indicates a higher similarity between the target image and the contrast image. In order to ensure the matching accuracy in the application, the threshold value may be set to be above 0.95, because if a two-dimensional image is used for the acquired target image and the pre-stored contrast image, the feature points extracted compared with the three-dimensional image are less, and therefore, a high matching degree between the two-dimensional images needs to be ensured by a high threshold value. Before the comparison, the target image can be subjected to operations such as graying, smooth filtering, denoising and the like, so that the target image has the effects of small storage space, less interference, reduced computation amount and the like. In addition, a specific embodiment of a contrast image is provided, namely a trace diagram with a background of connecting points, also called a grid diagram. The classification is carried out according to the difference of the number of the connecting points in the drawing, such as common nine-grid, sixteen-grid and the like. The nine-square grid shown in fig. 4 is a widely applied screen lock, and the connection points in the background of fig. 4 can form a plurality of different images through artificially defined track connection. When the method extracts the characteristic points of the target image and the comparative image, the characteristic points of the track and the characteristic points of the connecting points are extracted, so that the method not only can extract the characteristic points of the image of the track, but also can extract the characteristic points of the background of the connecting points, and can extract the position relation between the track and the connecting points as the characteristic points. By adopting the method, the more the extracted feature points are, the higher the matching accuracy is and the higher the safety is relatively under the preset condition of a certain similarity threshold value. In addition, the user can directly set the track graph with the connection point background in the conventional screen locking mode as the contrast image, and the user does not need to additionally memorize the pre-stored contrast image.
