Description

Technical Field

[0001] The invention relates to an electronic telescope, and in particular to a method and system for superimposing content on a screen of an electronic viewing telescope. Background Art

[0002] When tourists use a telescope to view unfamiliar scenes for the first time, they often do not know what the unfamiliar scenes displayed in the telescope are, and they often want to know the name and brief introduction of each scene displayed in the telescope so that they can carefully view the specific scenes of interest in a targeted manner. Currently, the traditional telescopes on the market cannot meet the expectations of customers. Moreover, even if some introductions about the scenes can be displayed on the electronic screen of the electronic telescope, since the user will adjust the lens pointing and focal length of the telescope at any time during the use of the telescope, the position of the scene displayed on the screen of the telescope will change relatively. How to make the introduction content change with the change of the position of the scene, so that the text (picture) is closely attached to the scene, is also a problem that needs to be solved. Summary of the invention

[0003] In view of the deficiencies of the prior art, the present invention discloses a method and system for superimposing text or picture content on the screen of an electronic viewing telescope.

[0004] The technical solution adopted by the present invention is as follows:

[0005] A method for superimposing text or picture content on a screen of an electronic viewing telescope, comprising:

[0006] Step 1: The horizontal rotation angle sensor installed on the horizontal platform and the pitch rotation angle sensor installed on the pitch platform transmit the recorded tilt angle parameters and coordinate information of the electronic viewing telescope to the central processing unit;

[0007] Step 2: The central processing unit combines the landscape position parameters with the focal length and focus data parameters output by the telescope lens, and uses character overlay technology to match the characters input on the mobile phone and display them at the corresponding position on the telescope screen;

[0008] Step 3: The central processing unit automatically locks the scene and the character position according to the built-in software algorithm and the change in scene size caused by the change in the focal length of the telescope lens, ensuring that the character position will not shift as the user moves the electronic viewing telescope.

[0009] A system for superimposing content on the screen of an electronic sightseeing telescope comprises an electronic sightseeing telescope and a mobile phone; the electronic sightseeing telescope comprises a column; a horizontal pan head is installed on the top of the column; a horizontal rotation angle sensor is installed in the horizontal pan head; a telescope screen is installed above the horizontal pan head; a pitch pan head is fixed to the rear side of the telescope screen; a telescope lens is fixed to the rear side of the telescope screen through the pitch pan head; a pitch rotation angle sensor is installed in the pitch pan head; a QR code is fixed on the column; the mobile phone can display a text input interface on the screen; the electronic sightseeing telescope is installed with a Bluetooth device and a WIFI device; the mobile phone is installed with a Bluetooth device and a WIFI device; and a central processing unit is also arranged in the electronic sightseeing telescope.

[0010] The beneficial effects of the present invention are as follows:

[0011] 1. The present invention provides a method for superimposing and marking text or pictures at the exact position of the scene displayed on the screen of a fixed variable focal length electronic viewing telescope. During use, a simple text or picture introduction of the scene can be displayed on the screen of the electronic telescope while the picture is displayed, thereby improving the user experience quality.

[0012] 2. The text superimposed on the screen of the fixed variable focal length electronic viewing telescope of the present invention can automatically move with the movement of the camera lens and zoom in / out, and can be accurately superimposed on the corresponding scene, and its display position will not deviate from the position of the scene;

[0013] 3. You can directly use your mobile phone to input the characters that need to be superimposed on the screen of the fixed variable focal length electronic viewing telescope, which is easy to use;

[0014] 4. When the user moves the telescope to view a scene, whether rotating or zooming, as long as the scene does not leave the picture, the text will automatically move with the scene and always "stick" to the scene, so that the user can quickly find and identify the scene.

[0022] The present invention obtains the three-dimensional geographic coordinates of landscapes and scenes through the data parameters output by the horizontal rotation position sensor and the pitch rotation position sensor installed on the horizontal platform / pitch platform of a fixed variable-focal-length electronic viewing telescope and the zoom lens magnification / zoom position data parameters, and uses a mobile phone to mark the names of the landscapes and scenes and other static or dynamic information text / pictures on the telescope screen in combination with special software and algorithms.

[0023] The specific implementation of the present invention will be described below in conjunction with the accompanying drawings.

[0024] Figure 1 It is a schematic diagram of the system of the present invention. Figure 1 As shown, a system for superimposing text or picture content on the screen of an electronic sightseeing telescope includes an electronic sightseeing telescope and a mobile phone. The electronic sightseeing telescope includes a column 6. A horizontal pan head 4 is installed at the top of the column 6. A horizontal rotation angle sensor 5 is installed in the horizontal pan head 4. A telescope screen 7 is installed above the horizontal pan head 4. A pitch pan head 3 is fixed to the rear side of the telescope screen 7. The telescope lens 1 is fixed to the rear side of the telescope screen 7 through the pitch pan head 3. A pitch rotation angle sensor 2 is installed in the pitch pan head 3. A QR code 8 is fixed on the column 6. The mobile phone can display a text input interface on the screen. The electronic sightseeing telescope is equipped with a Bluetooth device and a WIFI device. The mobile phone is equipped with a Bluetooth device and a WIFI device. A central processing unit is also provided in the electronic sightseeing telescope. The Bluetooth device of the electronic sightseeing telescope and the Bluetooth device of the mobile phone can match each other. The WIFI device of the electronic sightseeing telescope and the WIFI device of the mobile phone can match each other.

[0025] The present invention also discloses a method for superimposing content on the screen of an electronic viewing telescope, comprising the following steps:

[0026] Step 1, the horizontal rotation angle sensor 5 and the pitch rotation angle sensor 2 installed on the horizontal pan / tilt head 4 transmit the recorded tilt angle parameters and coordinate information of the electronic viewing telescope to the central processing unit;

[0027] Step 2, the central processing unit combines the landscape position parameters with the focal length and focus data parameters output by the telescope lens 1, and uses character overlay technology to match the characters input on the mobile phone and display them at the corresponding position of the telescope screen 7;

[0028] Step 3: The central processing unit automatically locks the scene and the character position according to the built-in software algorithm and the change in scene size caused by the change in the focal length of the telescope lens 1, ensuring that the character position will not shift as the user moves the electronic viewing telescope.

[0029] Figure 2 to Figure 7 The method of operation of a practical embodiment is shown.

[0030] Figure 2 This is a diagram of using a mobile phone to scan the code and enter the settings interface. Figure 2 As shown, use an authorized mobile phone to scan the QR code 8 on the column 6 of the fixed variable focal length electronic viewing telescope and enter the user name and password. The mobile phone will enter the setting interface of the fixed variable focal length electronic viewing telescope after scanning the code, and characters can be entered in the setting interface through the mobile phone.

[0031] Figure 3 This is a schematic diagram of the initial state of the telescope LCD screen after it is turned on. Figure 3 As shown, after the telescope is turned on, the initial state is at the widest angle end of the zoom telescope lens 1.

[0032] Figure 4 This is a schematic diagram of the telescope pointing at the scene. Figure 4 As shown, rotate the horizontal platform 4 and the tilt platform 3 of the telescope, and align the white cross mark in the center of the image of the telescope screen 7 with the scene (Oriental Pearl Tower) to be superimposed with text or pictures.

[0033] Figure 5 Figure 1 is a schematic diagram of locking the scene and character positions. Figure 5 As shown, input text on the mobile phone interface and press the "+" button 9 on the telescope handle to lock the scene and the character position.

[0034] Figure 6 This is a schematic diagram of character superposition. Figure 6 As shown, a character overlay interface will pop up on the mobile phone App interface, fill in the name of the scene, such as "Oriental Pearl Tower", in the box, and the corresponding scene on the telescope screen 7 will be marked with the same characters. After confirming that the input characters are correct, press the "Upload" button on the App setting interface, and the characters will be uploaded to the correct position of the telescope screen 7 of the fixed variable focal length electronic viewing telescope.

[0035] Figure 7 This is a schematic diagram of the completed character setting. Figure 7As shown, after repeated multiple times, all the scenes to be marked are marked with characters. When the user moves the telescope to view the scene of interest, such as the Oriental Pearl Tower, no matter the telescope is turned or zoomed, as long as the scene, such as the Oriental Pearl Tower, does not appear on the screen, the characters will "follow" the scene, such as the Oriental Pearl Tower, and move automatically, and always "stick" to the scene, so that the user can quickly find and carefully zoom in to view the scene, such as the Oriental Pearl Tower.

[0036] In this specific embodiment, the central processing unit in the electronic viewing telescope ensures that the characters input on the mobile phone match and are displayed at the corresponding position on the telescope screen 7 through the above steps 1 to 3, and can automatically lock the scene and character position according to the built-in software algorithm and the change in scene size caused by the focal length change of the telescope lens 1, ensuring that the character position will not shift as the user moves the position of the electronic viewing telescope.

[0037] The above description is an explanation of the present invention, not a limitation of the present invention. The scope of the present invention is defined in the claims. The present invention may be modified in any form without violating the basic structure of the present invention.
