Problems solved by technology

[0005] In the first method and the second method, since part of the image of the projected object is projected on the finger, the projected object looks fragmented, the visual effect is not good and the characteristics of projection are not fully utilized, and the second method requires the user to The fingers make pinch and release movements, and the fingers need to be kept in the pinch state during the process of dragging the projected object. If the operation time is too long, the burden on the fingers will be heavy; the third method, because it is difficult to distinguish the floating state and confirmation state, so it is more difficult to design the operation of selecting the projected object and releasing the object

Embodiment 1

[0080] The embodiment of the present invention provides a method for operating projection objects, see figure 1 , the method flow provided by this embodiment includes:

[0081] 101: Detect whether there is an operating body in the projection area; wherein, a display interface is projected through the projection unit, and the display interface includes N projection objects; when there is a bearing surface in the projection area, the display interface is displayed on the bearing surface;

[0082] 102: When there is an operating body in the projection area, determine whether the difference between the first distance of the operating body relative to the projection unit at time T1 and the second distance relative to the projection unit at time T2 satisfies a predetermined distance;

[0083] 103: When the difference between the first distance of the operating body relative to the projection unit at time T1 and the second distance relative to the projection unit at time T2 satisfies...

Embodiment 2

[0106] The embodiment of the present invention provides a method for operating a projection object. For the convenience of description, the content of Embodiment 1 and figure 2 The shown projection system architecture diagram explains in detail the manner of operating the projection object provided by this embodiment. Before elaborating the method provided by this embodiment, the figure 2 The projection system architecture diagram is shown for illustration. The projection system mainly includes a projection unit, a camera unit, a position sensing unit and a control unit. The control unit is a computer, including CPU (Central Processing Unit, central processing unit), memory, ROM (Read-Only Memory, read-only memory), hard disk and so on. The program running on the controller obtains the required information by processing the image data from the camera unit, and then updates the content to be projected, and then projects it through the projection unit. The projection unit h...

Embodiment 3

[0157] An embodiment of the present invention provides a device for operating a projection object, which is used to execute the method provided in Embodiment 1 or Embodiment 2 above, see Figure 5 , the device consists of:

[0158] The first detection module 51 is configured to detect whether there is an operating body in the projection area;

[0159] The first determining module 52 is configured to determine whether the difference between the first distance of the operating body relative to the projection unit at time T1 and the second distance relative to the projection unit at time T2 satisfies a predetermined distance when there is an operating body in the projection area;

[0160] Executing module 53, configured to, when the first determining module 52 determines that the difference between the first distance of the operating body relative to the projection unit at time T1 and the second distance relative to the projection unit at time T2 satisfies a predetermined distanc...

Abstract

The invention discloses a method and a device for operating a projection object, belonging to the technical field of multimedia. The method includes: detecting whether there is an operating body in the projection area; when there is an operating body in the projection area, determining whether the difference between the first distance of the operating body relative to the projection unit at T1 and the second distance of T2 relative to the projection unit is Satisfy the predetermined distance; when the difference between the first distance of the operating body relative to the projection unit at T1 and the second distance relative to the projection unit at T2 satisfies the predetermined distance, perform the first operation on the first projection object on the operating body . When the present invention detects that there is an operating body in the projection area, when it is determined that the difference between the first distance of the operating body relative to the projection unit at time T1 and the second distance of the operating body relative to the projection unit at time T2 satisfies a predetermined distance, the operating body Operations are performed on the projected object, so the operation method is more intuitive, natural and simple, the visual effect is better, and the characteristics of projection are fully utilized.

Description

technical field [0001] The invention relates to the field of multimedia technologies, in particular to a method and device for operating projection objects. Background technique [0002] With the continuous development of multimedia technology, projection equipment has been widely used. When the user wants to operate a certain projection object in the projection plane, he needs to return to the terminal connected to the projection plane for corresponding processing. Therefore, in order to reduce the round-trip time spent by the user between the projection plane and the terminal, how to realize the operation on the projection object on the projection plane without returning to the terminal has become a key issue. [0003] In the prior art, three methods are generally adopted when manipulating the projection object. The first method adopts the same method as that of the touch screen. For example, when the user clicks a certain projection object on the projection plane with h...
