Embodiment 1
[0081] In order to facilitate the understanding of this embodiment, firstly, a projector that performs the object positioning method disclosed in the embodiment of the present application is introduced in detail.
[0082] Such as figure 1 Shown is a block diagram of the projector. The projector 100 may include a memory 111 , a processor 113 , an acquisition unit 115 , and an optical engine 117 . Those of ordinary skill in the art can understand that, figure 1 The shown structure is only for illustration, and does not limit the structure of the projector 100 . For example, projector 100 may also include a ratio figure 1 more or fewer components than shown in, or with figure 1 Different configurations are shown.
[0083] The aforementioned memory 111 , processor 113 , acquisition unit 115 , and optical machine 117 are electrically connected to each other directly or indirectly to realize data transmission or interaction. For example, these components can be electrically co...
Embodiment 2
[0090] see figure 2 , is a flow chart of the object positioning method provided by the embodiment of the present application. The following will be figure 2 The specific process shown will be described in detail.
[0091] Step 202, acquiring the current image of the target area.
[0092] In this embodiment, the current image includes an image of the projection area and an image of the non-projection area.
[0093] In this embodiment, the target area may be an area corresponding to the projection direction of the projector. Exemplarily, the target area may include a projection area, for example, a projection screen. Exemplarily, the target area may include a projection area, for example, a projection screen. The target area may also include a non-projection area, for example, the area around the projection screen.
[0094] Exemplarily, the above-mentioned projection area may be an area for displaying a picture projected by a projector. For example, the projection area ...
Embodiment 3
[0162] Based on the same application idea, the embodiment of the present application also provides an object positioning device corresponding to the object positioning method. Since the problem-solving principle of the device in the embodiment of the present application is similar to the aforementioned embodiment of the object positioning method, in this embodiment For the implementation of the device, reference may be made to the description in the embodiments of the above method, and repeated descriptions will not be repeated.
[0163] see Image 6 , is a schematic diagram of the functional modules of the object positioning device provided in the embodiment of the present application. Each module in the object positioning apparatus in this embodiment is used to execute each step in the above method embodiment. The object positioning device includes: an acquisition module 301, a first determination module 302, and a second determination module 303; wherein,
[0164] An acqu...
