Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
The embodiment of the invention aims to provide a topic searching method of intelligent equipment, and solves the problems that in the prior art, when topics are searched, operation is troublesome and searching efficiency is low. In the prior art, when a learning machine or other learning equipment is used for searching, an application program for searching topics needs to be opened first, a camera is started in the opened state of the application program, a picture including topic contents is shot by the camera, then the topic contents in the picture are subjected to character recognition by a character recognition program, a user selects the required topic contents, or the recognition result is directly sent to a server or a local topic database, and the corresponding topic results are displayed in the equipment. To describe in detail how to solve the above problems, the present invention will be described in detail below with reference to the accompanying drawings.
The first embodiment is as follows:
fig. 1 shows an implementation flow of a title search method for an intelligent device according to a first embodiment of the present invention, which is detailed as follows:
in step S101, in the black screen state, cursor display is turned on, and the cursor is displayed on the screen acquired by the camera.
Specifically, in the embodiment of the present invention, the cursor display is started, a hardware switch may be set in the learning machine and other devices, and the hardware switch is switched to the on state, so that the learning machine and other devices can be quickly switched to the title search state in the standby state of shutdown.
In a preferred embodiment, the hardware switch for turning on the cursor display is different from the switch of the device. When the screen is in a black screen state, when a switch of the equipment is turned on, the system enters a main interface, and different application programs can be operated on the main interface. When a hardware switch for starting cursor display is opened, the system starts the camera, and displays the cursor in a picture acquired by the camera.
The picture acquired by the camera can be displayed in a full-screen mode or in a window mode in a designated area of the screen. The cursor may be displayed in a middle position of the screen in a default display manner, or may be preset to be displayed in another position of the screen.
The user can change the position of the cursor by touching or moving the mouse, for example, the cursor is moved to the position of the title in the screen by touching.
In step S102, it is detected whether the cursor is in a stationary state in the screen.
Specifically, after the cursor display is started, the picture aligned with the camera may not be the picture of the topic, and the user is required to adjust the picture aligned with the camera, or adjust the position of the topic to be identified by adjusting the cursor. After the user adjusts the picture where the title to be searched is located, in the picture, the position of the cursor in the picture is in a static state, which indicates that the user is aligned with the title to be searched, and if the cursor is in a relative motion state in the picture, which indicates that the user is currently moving the camera or moving the cursor, the position where the title is located cannot be determined.
Therefore, in the embodiment of the present invention, detecting whether the cursor is in a static state in the picture may include detecting whether the picture acquired by the camera changes, and detecting whether the cursor receives a movement instruction.
When a user determines that the current picture of the camera includes the topic content to be searched, the user needs to adjust the device to be in a static state, keep the picture acquired by the camera unchanged, and further adjust the position of the topic content through a cursor.
If the user is in a still state, and the time that the cursor is still reaches a certain duration, for example, the time in the still state exceeds 500-.
In step S103, if the cursor is in a static state in the screen, the title content in the screen is searched according to the position of the cursor.
Specifically, if the cursor is in a static state in the screen, the position currently indicated by the cursor is the position where the title is located. Therefore, the invention automatically searches the position of the title content in the picture through the position of the cursor, thereby efficiently searching the title in the picture and avoiding the complicated operation of the user.
The title content in the picture is searched according to the position of the cursor, and the search of the title content can be performed according to a preset title range identifier by taking the position of the cursor as a center, for example, a line feed character is usually generated between titles, or the distance between titles is usually larger than the normal distance, and the size of the content of the title is determined.
After the title content is found, a voice prompt or a display prompt mode can be sent to prompt the currently found title content in the picture, prompt the user to confirm whether the found title content is correct, if the found title content is correct, the user can continue to keep the state and wait for returning a search result, and if the found title content is incorrect, the position of a cursor can be changed, or the picture obtained by a camera is changed, and the title content is obtained again.
In step S104, the searched topic content in the screen is identified, and a search is performed according to the identified topic content.
After the position and the size of the title content in the picture are determined, the title content in the region can be identified through a character identification program, and in terms of identification efficiency, the method only needs to identify a part of the picture where the title is located, so that the efficiency of identifying the title in the picture can be improved.
In the embodiment of the invention, when a user starts cursor display, a cursor is displayed in a picture acquired by a camera, a system detects whether the cursor in the picture is in a static state, when the cursor is in the static state, title content is searched according to the position of the cursor, and searching is carried out according to the identified title content, so that the method can automatically search after the cursor is opened to display an aligned title, the convenience of user operation is greatly simplified, the efficiency of title searching is improved, and the interference caused by the fact that other application programs can be operated when the user enters a system interface can be avoided due to the fact that the cursor is opened and the image is acquired in a black screen state, and the convenience in use is improved and the improvement is facilitated.
Example two:
fig. 2 shows an implementation flow of a title search method for an intelligent device according to a second embodiment of the present invention, which is detailed as follows:
in step S201, in a black screen state, a cursor display is started, and a first cursor pattern is displayed in a picture acquired by a camera, where the first cursor pattern includes a center pattern of a cursor and a border pattern of the cursor adjacent to the center pattern.
Specifically, as an implementation manner of the cursor according to the embodiment of the present invention, as shown in fig. 3, the cursor includes a center pattern and a border pattern of the cursor, the center pattern is a cross-shaped cursor pattern, and the border pattern of the cursor is a four-corner border pattern. Of course, this is only one embodiment, and the center pattern and the border pattern of the cursor can be flexibly replaced according to the user's needs.
In the embodiment of the present invention, the cursor includes two display states, the first is a complete display state of the cursor, and the center pattern of the cursor is adjacent to the frame pattern of the cursor. Thereby determining the title content in the picture.
And in the second state, after the first state and after the cursor is detected to be in a static state in the picture, the border pattern of the cursor is automatically searched for the border of the title, and the border pattern of the cursor is displayed at the border position of the title, wherein the central pattern can be adjusted to be displayed at the central position of the border pattern of the cursor according to the position of the searched border.
In step S202, it is detected whether the cursor is in a stationary state in the screen.
In step S203, if the cursor is in a static state in the screen, the position of the title content is determined according to the center pattern of the cursor.
Specifically, in the embodiment of the present invention, the cursor is in a static state in the screen, and includes two requirements:
1) the content in the picture is in a static state, that is, the picture content acquired by the camera does not change, and the user confirms that the current picture comprises the title to be searched;
2) the cursor on the display screen of the device such as the learning machine is in a static state, and at this time, the user does not move the cursor through touch or mouse or other operation modes, that is, the user confirms that the current position of the cursor is at the position of the title.
In step S204, the boundary of the theme content is searched for according to the screen, and the border pattern of the cursor is displayed at the position of the boundary of the theme content.
In the embodiment of the present invention, the method further includes searching for a boundary of the topic content, wherein the step of searching for the boundary of the topic content according to the picture includes:
searching the boundary of the title content according to a line feed identifier included in the picture content;
or, acquiring the line spacing of the characters included in the picture content, and judging that the current position is the boundary of the topic when the line spacing is larger than a preset line spacing value in the picture.
The preset line space may be a line space set for general characters. Because the distance between the pictures changes along with the distance between the pictures, in order to improve the accuracy of the judgment, the judgment can be carried out according to the ratio of the characters to the distance, for example, when the ratio of the size of the characters to the line spacing is smaller than a preset value, the boundary position of the current action topic is judged. And displaying a border pattern of the cursor at the boundary position. In order to facilitate the confirmation of the position of the frame, the frame pattern of the cursor can be displayed in a flashing manner.
In step S205, the searched topic content in the screen is identified, and a search is performed according to the identified topic content.
As shown in fig. 4, which is a schematic display diagram of the search result, a full screen display mode may be adopted, and the search result is displayed in a black background mode, which is beneficial for the user to concentrate on the search result more, thereby being beneficial to improving the learning efficiency.
According to the embodiment of the invention, after the area where the topic content is located is determined through the border pattern of the cursor, the efficiency of identifying the topic content can be further improved, and the accuracy of searching the topic can be improved by selecting the topic content through the border pattern of the cursor.
