For example, if the zoom optical element captures the image of the target, in addition to uploading the image of the target and its second coordinate to the cloud server, as shown in Figure 4, the electronic device 14 will The image and the second coordinate are transmitted to other electronic devices via the cloud server 24, such as the second electronic device 34 of another user, and the image of the target 20 is shared with other users for viewing. Other users may look at the image of the target 20 first. If they are interested in this target 20, they may search the name and related information of the target 20 from the cloud server 24 according to the second coordinate.

The way for other users to obtain the target image and the second coordinate is as follows: the first electronic device 14 uploads the second coordinate (xt, yt) to the cloud server 24, and at least one application program can be installed in the first electronic device 14. (Such as the Facebook application), the first electronic device 14 leaves a message or marks the second electronic device 34 on a website (such as a Facebook website or other social networking site) or an application, and the second electronic device 34 receives After commenting or marking, the second coordinate and target image can be obtained through the cloud server 24. For example, the first electronic device 14 uploads a photo of the target object 20 and the second coordinate to Facebook through the internally installed Facebook application, and leaves a message or marks another user of the second electronic device 34. The sharing target object 20 is A beautiful-looking building. At this time, if the user of the second electronic device 34 is interested in seeing the image of the target, he will download and save the second coordinate. If he is not convenient, he will search for the target on the Internet based on the second coordinate. Relevant information of the object 20 or go in person to find the target object 20 according to the second coordinates stored in the second electronic device 34.

If other users want to see the target with their own eyes after watching the image, they can find the specific position of the target 20 according to the second coordinate. In Figure 4, the second electronic device 34 of another user receives After the second coordinate of the target object 20, the search for the target object 20 is started. Since the second electronic device 34 also has a positioning function, it is known that the coordinates of the second electronic device 34 are (x ₂ , y ₂ ) and the first coordinate of the target object 20 Two coordinates (x _t , y _t ), the distance d ₂ between the second electronic device 34 and the target 20 can be calculated, and the second deflection angle detecting element 32 can provide a steering angle, so the second electronic device 34 You can give a reminder when you are close to the target 20, and tell how many angles θ ₂ should be rotated to see the target 20. For example, remind the user to turn 20 degrees to the right, and 100 meters in front is the target. In this embodiment, other users do not need to be equipped with the second zoom optical element 30, and only need the second deflection angle detecting element 32 and the second electronic device 34 to find the target object 20.

If other users are far away from the target 20, such as another city, they may not search the target 20 first, and then start the program in the second electronic device 34 after the user has also reached the city of the target 20 To guide the user to the target 20, and the second electronic device 34 will issue a reminder to the user after the target 20 has appeared in the visible range.

There can be more than one zoom optical element in the present invention. When there are two optical zoom elements, for example, a liquid crystal lens is installed on the left and right lenses of the glasses, the two optical zoom elements can be sensitive to two targets at the same time. An image is generated on a component (such as a CMOS sensor). The imaging of a distant target overlaps with a closer target, and the approximate distance can be determined. In this way, it was necessary to scan from 0V all the time before capturing multiple images to find The image with the strongest contrast is the image with the sharpest focus. The use of two optical zoom elements can greatly reduce the range of voltage detection. For example, if the approximate position of the target is 50 meters away, a 20-30V The voltage can be used to focus, instead of starting from 0V.

In summary, the present invention provides a zoom optical system for calculating the coordinate position of a target and a method for sharing information of the target. The zoom optical system, the deflection angle detection element, and an electronic device are used to obtain a user and a target respectively. Distance, included angle, and positioning coordinates. The coordinates of the target are calculated based on these parameters. It does not require multiple zoom optical elements to calculate the target coordinates in a triangular positioning method, which can greatly save costs, and detect deflection angles such as electronic compass or gyroscope. Components are components built into most electronic devices and generally do not need to be purchased separately. In addition, the present invention shares the coordinates of the target with other users, so that other users can find the target based on the coordinates. If the user is not able to go there, he can also use the coordinates to check the information about the target online, eliminating the need to In order to speed up the search of target information, it can also avoid finding similar objects instead of the target itself.
