Detailed Description
The present invention will be described in further detail with reference to the drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not to be construed as limiting the invention. It should be further noted that, for the convenience of description, only some structures related to the present invention are shown in the drawings, not all of them.
Example one
The projector is a device that can project images or videos onto a curtain, and can be connected with a computer, a VCD, a DVD, a BD, a game machine, a DV, etc. through different interfaces to play corresponding video signals. Projectors are now widely used in homes, offices, schools and entertainment venues.
In the early education stage in the growth process of the children, in order to arouse the learning interest of the children and enable the children to remember more deeply, the story of the children is directly displayed in a projection mode, and the sound of the people's attraction, namely the frequency of the opposing of the. The camera device and the artificial intelligence module are added, so that interaction between a person who watches the projection story and the story line can be realized, and the idea can be expressed.
Fig. 1 is a flowchart of a method for processing a projected image according to an embodiment of the present invention, where the embodiment is applicable to a case of processing a projected image, and the method may be performed by a projected image processing apparatus, and the apparatus may be configured in a terminal, for example. As shown in fig. 1, the method specifically includes:
and S110, identifying the action of the first object.
The first object is a person who views the projection image or video, and may be a child or an adult. Specifically, an image and/or a video of the first object can be captured by the camera and uploaded to the processor. Then, the processor carries out pattern recognition on the acquired image and/or video of the first object, and whether the first object carries out drawing or not is judged.
S120, when the first object drawing is determined, a first image drawn by the first object is obtained.
When it is determined that the first object is drawing, the first image may be extracted in the captured image and/or video. Specifically, the first image can be separated from the original picture or image into an individual image layer by using a matting method, the main function is to prepare for image synthesis in the subsequent steps, and the method can be specifically realized by extracting a filter, extracting an external filter, a channel, calculating, applying an image method and other algorithms.
And S130, replacing the current projection image with the target projection image according to the first image.
Acquiring a current projection image and determining a second image to be replaced in the current projection image; and replacing a second image in the current projection image with the first image to obtain the target projection image.
Wherein the current projection image is an image projected by the projector when the first object is identified to be drawn. The determination of the second image is determined based on the properties of the first image. Specifically, when the first image is acquired, the category and the specific content of the first image are further analyzed, and the category of the first image may be contents such as cartoon characters, buildings, animals and plants, fruits, natural landscapes and the like. For example, after the first image is identified as a big tree, whether a tree or a plant exists in the current projection image is matched, if so, the tree or the plant in the current projection image is determined as a second image and is extracted from the current projection image, namely, the same type of substitution of the first image as the second image is carried out, the appearance presented by the original projection image is replaced by the appearance presented by the projection image in the eyes of a child or a big person who watches the projection, and therefore the output of the idea of a projector and the interaction with the projection content are realized.
Further, before the target projection image is finally obtained, the projection image processing method further includes the steps of: comparing the first image with the second image to determine whether the contours of the first image and the second image match; if not, smoothing the difference between the first image and the second image according to the pixel information of the current projection image; and coloring the first image according to the pixel information of the current projection image.
Specifically, the purpose of the above steps is to make the fusion of the first image and the current projection image more natural, so that the finally obtained target projection image has no sense of incongruity. When the color difference exists between the first image and the current projected image or the first image and the second image are not matched completely, interpolation can be adopted to correct the target projected image. The interpolation method can be a nearest neighbor interpolation method, a bilinear interpolation method, a bicubic interpolation method of a 4 x 4 pixel neighborhood, a Lanczos interpolation method of an 8 x 8 pixel neighborhood and the like according to the characteristics of the image data.
Preferably, the projection image processing method further comprises saving the target projection image, and generating a new story set. The idea of the viewer can be recorded, memory points are formed, and the rich imagination and learning interest of the viewer are stimulated.
According to the technical scheme, the action of the projection viewer is identified, the drawing of the projection viewer is collected during drawing, the drawing of the projection viewer replaces the content in the projection image, the problems that the projection viewer cannot output own ideas and interacts with the projection content are solved, the combination of the drawing drawn by the projection viewer and the content of the projection image is realized, the viewing and learning interests of the projection viewer can be stimulated, and the projection viewer can actively express own ideas.
