Detailed Description
The present invention will be described in detail with reference to the following embodiments in order to fully understand the objects, features and effects of the invention, but the present invention is not limited thereto.
Fig. 1 is a flowchart illustrating a method of selecting a news screen and delivering a picture through a mobile terminal according to an embodiment of the present invention. As shown in fig. 1, the method comprises the steps of:
step S101, a news screen receives a service request of a user, informs a sensing device to capture a screen selection action made by the user holding a mobile terminal and measures position information of the mobile terminal so as to judge whether the screen selection action meets a preset rule.
The sending, receiving and the picture transferring in the subsequent steps of the service request all relate to data transmission between the mobile terminal and the news screen, so the step firstly comprises configuring the connection relationship between the mobile terminal and the news screen. Because the user utilizes mobile terminals with strong portability, such as smart phones and tablet computers, to make screen selection actions, the connection between the mobile terminals and the news screen in a wireless mode is more flexible. The transmission of the notification signal between the sensing device and the news screen may also occur in a manner that is determined by the specific circumstances, for example, as shown in fig. 2, the sensing device is adjacent to the news screen and is fixed in relative position, and a wired connection may be used.
Here, the wireless connection includes various wireless connection modes in the prior art, such as Wi-Fi, bluetooth, infrared connection, and the like, and can be flexibly selected according to needs. Considering that the Wi-Fi connection has a longer transmission distance and a faster transmission speed and is more suitable for the application environment of the news screen and the picture transfer requirement, the wireless connection between the mobile terminal and the news screen is configured as the Wi-Fi connection in the invention.
The user sends a service request to the news screen through the mobile terminal. For mobile terminals such as smart phones, special client programs can be provided for the mobile terminals, and users can operate the programs as required to make selections such as request sending, transmission modes, display modes and the like. Correspondingly, a special interface program is arranged at the news screen end and responds to the service request sent by the mobile terminal.
The position information in this step generally refers to the relative position information of the mobile terminal with respect to a predetermined reference object, for example, in the preferred embodiment of the present invention shown in fig. 2, the capture point of the sensing device is used as the reference object.
Any simple action or combination of actions may be used as the preset rule, such as simple limb movements, gestures, static gestures, and the like. In the present invention, a user may need to display a mobile terminal picture on a news screen, and usually hold the mobile terminal to perform a screen selection action, so that the preset rule may be set as: the mobile terminal screen is close to the target screen, and the state that the mobile terminal screen is parallel to the target screen and the distance of the mobile terminal screen is not more than the preset distance value is kept to be higher than the preset time value. For example, the preset distance value is 3cm, and the preset time is set to 3 s.
And step S102, calculating the coordinates of the mobile terminal in a pre-established coordinate system according to the position information.
The pre-established coordinate system may be selected taking into account a number of factors. For example, in fig. 2 where the news screen is located on a flat wall and the sensing device is adjacent to the news screen, the flat coordinate system coinciding with the flat surface may be selected as the pre-established coordinate system, which may require the user to make a selection action at a location closer to the news screen. If the sensing device is separated from the news screen and is far away, or the position of the news screen is not easy to be accessed by a user, the plane coordinate system can be selected as a position which can be easily accessed by the user, for example, the sensing device is arranged above an office table, the pre-established coordinate system can be a plane coordinate system which is coincident with a table top, different coordinate areas of the table top correspond to different target screens, the user holds the mobile terminal to stop at a certain distance above a certain area so as to select the corresponding target screen, and further highlights the currently selected target screen to feed back information to the commentator in real time according to the position of the mobile terminal, and if the stopping time is more than 3s, the target screen is selected. If the news screen occupies a plurality of walls of the exhibition hall, a sensing device may be mounted on the plurality of walls or a suitable three-dimensional coordinate system may be selected, and for the annular screen, a cylindrical coordinate system may also be selected.
Here, the preset rule in step S101 may be adjusted according to the position of the sensing device and a specific preset coordinate system, for example, the mobile terminal screen is close to the desktop and is kept parallel to the desktop at a distance of less than 3cm, and the duration is greater than 3S.
The sensing device in the invention comprises a sensing component for measurement and a processing component for calculating and processing data. The sensing device indirectly calculates the coordinates of the mobile terminal in the pre-established coordinate system according to the relative position information of the mobile terminal relative to a certain pre-established reference object, the coordinates of the reference object in the selected pre-established coordinate system are known or are easy to obtain, and the position information generally comprises information such as distance, angle and the like.
There are various sensing devices and corresponding ranging methods in the prior art, for example, TOF technology which combines a near infrared light sensor and a traditional camera is adopted to calculate the distance of a shot scene by calculating the time difference or phase difference between infrared light emission and reflection so as to generate depth information; adopting the optical coding technology of a common CMOS camera; and adopting an optical triangulation distance measurement technology of a PSD photoelectric device and the like. The person skilled in the art can select the above-mentioned prior art to use a separate sensor, transmitter, camera to construct the sensing device, or select the existing integrated product, such as various infrared distance measuring sensors, laser distance measuring devices, etc.
In the invention, before measuring the position information of the mobile terminal in the hand of the user, the sensing device firstly identifies the human body from the background environment and further identifies the mobile terminal, so that the sensing device also needs at least one camera component to acquire an environment picture. In the invention, a Kinect sensor is adopted as a sensing part in the sensing device, wherein the Kinect sensor comprises an RGB color camera and a 3D depth sensor consisting of an infrared emitter and an infrared CMOS sensor. The distance measurement is realized by combining a plurality of cameras, for example, an optical coding technology is adopted, an infrared emitter emits infrared light covering the visible range of the whole Kinect sensor, a camera group identifies an optical pattern on an object, the optical pattern changes along with the depth of a scene, and self-contained software analyzes depth information through the change, so that the distance of the object to be measured is obtained.
In addition, the Kinect sensor can capture the user action through the camera group, and compare the captured influence with the internal human body model, and track a plurality of parts of the human body in real time, therefore, besides the preset rules of gestures, static postures and the like in the step S101, the sensing device with the Kinect can recognize more complex human body actions or action combinations.
Fig. 2 is a schematic diagram illustrating a method for calculating coordinates of a mobile terminal according to a preferred embodiment of the present invention. In fig. 2, a news screen 400 includes 8 sub-screens, each having the same size, being regular rectangles, and having edges closely connected; the sensing device 500 is fixed directly above the center of the news screen 400 and the capture point of the sensing device is in the same plane as the news screen. The pre-established coordinate system is set to a planar coordinate system parallel to the plane of the news screen 400 with the upper left corner of the news screen 400 as the origin o. The sensing capture point h of the sensing device 500 is used as a reference point, and the vertical distance from the sensing capture point h to the news screen 400 is | hk |. The sensing device 500 acquires a distance D of a straight line segment between the screen of the mobile terminal 300 and the capture point h of the sensing device 500, an angle β between the straight line segment and a projected straight line thereof on a coordinate plane, i.e., the plane of the news screen 400, and an angle θ between the projected straight line and a horizontal axis of a plane coordinate system. The sensing device 500 calculates the vertical distance Z = dsinba from the screen of the mobile terminal to the news screen 400 in real time according to the distance and the angle. According to the preset rule of the screen selecting action in the present invention, when Z is less than 3cm and the state lasts for more than 3s, the sensing device 500 starts to calculate the coordinates of the screen of the mobile terminal 400 in the plane coordinate system: the abscissa x = | ok | -Dcos β cos θ, and the ordinate y = Dcos β sin θ - | hk |.
And step S103, comparing the coordinates of the mobile terminal in the pre-established coordinate system with the coordinate ranges of all the sub-screens of the news screen in the pre-established coordinate system to determine the target screen.
For example, in the preferred embodiment shown in fig. 2, each sub-screen has a length L and a width W, and the coordinates of the mobile terminal screen in the coordinate system are: l < x <2L, W < y <2W, then the target screen may be determined to be the second sub-screen from the bottom left.
In steps S102 and S103, the user may also continuously perform a selection action satisfying a preset rule on the multiple screens, and at this time, the sensing device sequentially calculates the coordinates of the mobile terminal in the preset coordinate system in each action according to the above method, and determines all the selected target screens.
And step S104, transferring the picture between the mobile terminal and the target screen through wireless connection.
The transfer of the picture between the mobile terminal and the target screen specifically includes the following two modes: the mobile terminal acquires a screen picture of the mobile terminal, sends the screen picture to a news screen and displays a putting-in mode on a target screen; and a taking-out mode that the news screen acquires the target screen picture, sends the target screen picture to the mobile terminal and displays the target screen picture on the screen of the mobile terminal.
In the putting-in mode, if a plurality of target screens continuously selected by a user are adjacent and spliced into a rectangular area with a proper proportion, the plurality of selected target screens are used as one screen to display a screen picture of the mobile terminal; and if the plurality of selected target screens are not adjacent or can not be spliced into the rectangular area, controlling each target screen to respectively display the screen picture of the mobile terminal.
In the taking-out mode, if a plurality of target screens continuously selected by a user are adjacent and display different sub-pictures of the same father picture, the father picture is displayed on the mobile terminal; if the selected target screens are not adjacent or do not display the sub-pictures of the same parent picture, the target screen pictures can be displayed on the mobile terminal screen together, or the target screen pictures can be displayed on the mobile terminal screen separately in sequence.
According to the method provided by the embodiment of the invention, after receiving a service request sent by a user through a mobile terminal, a news screen informs a sensing device to measure the position information of the mobile terminal and capture the screen selection action made by the user, if the selection action meets a preset rule, the coordinates of the mobile terminal in a preset coordinate system are calculated according to the position information, and the coordinates are compared with the coordinate ranges of all sub-screens in the same coordinate system, so that a target screen is determined and pictures are transferred between the mobile terminal and the target screen. According to the scheme, a reviewer does not need complex control equipment, and can select the target screen and transmit pictures by making simple selection actions through the mobile terminal. The mobile phone screen stays in front of the target screen and the mobile phone picture is transmitted to the target screen, so that the operation has a magic effect on a user, and the user experience can be improved.
