Detailed Description
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in further detail below.
According to the control scheme of the display terminal provided by the embodiment of the invention, the characteristics of strong laser signal directivity and high light source brightness can be utilized, and after the laser signal irradiates on the screen of the display terminal, the screen can perform diffuse reflection on the laser signal. Diffuse reflection represents a phenomenon in which light is reflected in all directions when it is projected onto a rough surface. The image collector captures the laser signals of diffuse reflection, positions the positions of the laser signals and transmits the positions of the laser signals to the display terminal. And the display terminal determines a corresponding target control according to the position of the laser signal and moves the cursor to the target control. And after the user confirms the target control, namely the control to be controlled, the user sends out a control signal through the remote controller. And the display terminal executes corresponding control operation according to the control signal and the target control.
Referring to fig. 1, a flowchart illustrating steps of an embodiment of a method for controlling a display terminal according to the present invention is shown, where the method may be applied to a display terminal, and the display terminal may be communicatively connected to an image collector and a controller, respectively. The method specifically comprises the following steps:
and 101, receiving a laser signal from a controller, and diffusely reflecting the laser signal to an image collector.
In the embodiment of the invention, a laser emitter may be disposed in the controller, and the controller may emit a laser signal to the screen of the display terminal through the laser emitter. The display terminal can diffusely reflect the laser signal from the controller. The image collector can be arranged above the front of the display terminal, and not only can collect images containing the display terminal, but also can capture laser signals diffused and reflected by the display terminal.
The image collector determines target coordinate information indicating a position of the laser signal on a screen of the display terminal using the collected image and the captured laser signal.
And 102, receiving target coordinate information returned by the image collector according to the laser signal, and positioning a target control of the display terminal according to the target coordinate information.
In the embodiment of the invention, the display terminal receives the target coordinate information returned by the image collector and positions the target control in the plurality of controls according to the target coordinate information. The target control is the control where the laser signal is located on the screen of the display terminal.
And 103, moving the cursor to the target control, receiving a control signal from the controller, and executing corresponding control operation according to the control signal and the target control.
In the embodiment of the invention, the display terminal moves the cursor to the target control, so that a user can confirm whether the control to be controlled is correct or not according to the cursor. If the user confirms that the control to be controlled is correct, a control signal can be sent out through the remote controller. And the display terminal executes the control operation aiming at the target control according to the control signal. If the user confirms that the control to be controlled is wrong, the position of the controller can be adjusted to change the position of the laser signal on the screen of the display terminal, and then the target control is repositioned.
In a preferred embodiment of the present invention, since the screen of the display terminal itself may emit the light signal, the light signal emitted from the screen may also generate the diffuse reflection phenomenon. The light signal sent by the screen is captured by the image collector after being subjected to diffuse reflection, and can interfere with the laser signal, so that the target coordinate information is inaccurate. Thus, a laser transmitter in the controller may emit a laser signal in a preset pattern (e.g., a special symbol, a bar code, etc.). On one hand, the laser signals of the preset patterns can be distinguished from the optical signals sent by the screen, and interference between the optical signals sent by the screen and the laser signals is avoided. On the other hand, the laser signal of the preset pattern may reduce damage to the eye compared to the laser signal of a single beam.
A matte film is arranged in front of a screen of the display terminal, a laser signal of a preset pattern is emitted onto the matte film, and the laser signal is diffusely reflected through the matte film. The image collector captures laser signals of preset patterns of diffuse reflection of the matte film.
The image collector can capture not only a laser signal of a preset pattern, but also an image of a screen containing the display device. And identifying the area where the screen is located from the image, and establishing a coordinate system in the area where the screen is located. For example, a coordinate system is established with the center point of the screen as the origin of the coordinate system, the long side of the screen as the abscissa axis, and the wide side of the screen as the ordinate axis. And mapping the laser signal to a coordinate system to obtain target coordinate information.
In a preferred embodiment of the present invention, the display terminal may establish a coordinate system in advance when positioning the target control. The coordinate system established by the display terminal and the coordinate system established by the image collector can correspond to each other. Namely, the coordinate information of the same coordinate point in the coordinate system established by the display terminal is the same as the coordinate information in the coordinate system established by the image collector. The plurality of controls in the display terminal have respective coordinate ranges in the coordinate system. And the display terminal compares the target coordinate information returned by the image collector with the coordinate range of each control, and if the target coordinate information belongs to the coordinate range of a certain control, the control is the target control.
After the display terminal positions the target control, the cursor on the screen can be moved to the target control. After confirming that the cursor moves to the correct control, the user can send an infrared signal to an infrared receiver in the display terminal through an infrared transmitter in the controller. The display terminal can implement the received infrared signal on the target control to execute the control operation corresponding to the target control. Or, a Bluetooth signal is sent to a Bluetooth module in the display terminal through the Bluetooth module in the controller. The display terminal can implement the received Bluetooth signal on the target control to execute the control operation corresponding to the target control.
In practical applications, the target control may be a number, a letter, a symbol, a function key, and the like. The infrared signal or bluetooth signal emitted by the controller typically indicates a confirmation operation. If the cursor moves above the target control "c", the controller transmits an infrared signal to the display terminal, the infrared signal indicating confirmation of selection of the letter "c", and inputs the letter "c" in the input field of the screen.
The user changes the position of the laser signal on the screen of the display terminal by adjusting the direction and the angle of the controller, and the image collector determines different target coordinate information according to the laser signals at different positions. And the display terminal positions different target controls according to different target coordinate information and executes control operation aiming at the different target controls.

As shown in fig. 2, a schematic diagram of a method for operating a television according to the present invention is shown.

The remote controller may include a laser transmitter, an infrared transmitter, an acceleration sensor, a bluetooth module, and a Micro Control Unit (MCU). The camera can be provided with a Bluetooth module. The bluetooth module in the television can communicate with the bluetooth module in the camera and/or the bluetooth module in the remote controller. An infrared receiver in the television may communicate with an infrared transmitter in the remote control. Matte films in televisions are used to diffusely reflect laser signals. And a laser transmitter in the remote controller is used for transmitting a laser signal to the matte film. An infrared transmitter in the remote controller is used for sending out an infrared signal. The Bluetooth module in the remote controller is used for sending out Bluetooth signals. And the MCU in the remote controller is used for taking charge of the operation of the laser transmitter, the infrared transmitter, the acceleration sensor and the Bluetooth module. An acceleration sensor in the remote controller is used for detecting the movement condition of the remote controller. Because the power consumption of the laser emitter is high, the laser emitter needs to be turned off when the laser emitter is not used, but the manual turning off of the laser emitter is inconvenient. Therefore, an acceleration sensor is provided for the remote controller, and whether the remote controller is moved is detected using the acceleration sensor. And if the remote controller is detected not to move within a certain time, the MCU automatically turns off the infrared transmitter. The certain time may be 10 seconds, and the like, and the numerical value, the unit, and the like of the certain time are not particularly limited in the embodiment of the present invention. The camera is used for collecting images of a television screen, capturing diffuse reflection laser signals, converting positions of the laser signals into coordinate information, and sending the coordinate information to the Bluetooth module of the television through the Bluetooth module.
In actual operation, when the acceleration sensor detects that the remote controller moves, the MCU is informed to wake up the laser transmitter, and the laser transmitter transmits a laser signal. The user adjusts the position of the laser signal on the television screen by adjusting the direction, the angle and the like of the remote controller. The laser signal is projected on the matte film, and the laser signal is diffusely reflected by the matte film. The camera captures the laser signals subjected to diffuse reflection, and maps the laser signals to the established coordinate system to obtain coordinate information of the laser signals. The camera sends the coordinate information to the Bluetooth module of the television through the Bluetooth module. And the television moves the cursor according to the coordinate information and moves the cursor to the control corresponding to the coordinate information. Therefore, the user can position a certain control on the television through the remote controller. Similarly, the user can adjust the direction, the angle and the like of the remote controller, and adjust other positions of the laser signal on the television screen, so as to position other controls on the television. Finally, the television receives the triggering operation of the remote controller for the plurality of controls, and the control corresponding to the plurality of controls is completed.
The embodiment of the invention provides a control method of a display terminal, and relates to the display terminal, an image collector and a controller. The display terminal can be in communication connection with the image collector and the controller respectively. The controller sends a laser signal to the display terminal, the display terminal diffusely reflects the laser signal to the image collector, and the image collector returns target coordinate information to the display terminal according to the laser signal. And the display terminal positions the target control according to the target coordinate information and moves the cursor to the target control. And executing corresponding control operation according to the target control and the control signal from the controller.
