In order to further understand the objects, structures, features and functions of the present invention, the following embodiments are described in detail.
Certain terms are used throughout the description and following claims to refer to particular components. As one of ordinary skill in the art will appreciate, manufacturers may refer to a component by different names. The present specification and claims do not intend to distinguish between components that differ in name but not function. In the following description and in the claims, the terms "include" and "comprise" are used in an open-ended fashion, and thus should be interpreted to mean "include, but not limited to.
Referring to fig. 1 to 2, there are shown schematic structural diagrams of a light carving projection system and a method according to a first embodiment of the invention. The light carving projection system 1 includes an intelligent projection device 10 and a mobile terminal 20. The smart projection device 10 includes a projection module 11, a scene capture module 12, a content processing module 13, and a communication module 14.
The projection module 11 is responsible for projecting the canvas image onto the projection area S. The projection module 11 may adjust the projection quality of the canvas image, such as brightness, sharpness, contrast, gamma value, etc. The projection area S includes at least one projected object (S1, S2, S3, S4 \8230;), which is an object with a real shape and surface (S1, S2, S3, S4 \8230;), which can be, but is not limited to, a wall background, a geometric block, a tree model, a model, etc.
The scene capturing module 12 is used for capturing the projection area S, and the scene capturing module 12 may employ, but is not limited to, a camera. Preferably, the scene capturing module 12 employs a high-definition camera to capture a higher-definition image, for example, a resolution of 1080p or 4K, for the projection module 11 to adjust the projection quality as a reference and create the light-carving projection content. Preferably, the position of the scene capture module 12 is the same as, and almost coincident with, the position of the projection module 11, so as to minimize the difference between the two fields of view. The position of the scene capturing module 12 and the position of the projecting module 11 may be different, and coordinate mapping is performed by an equal-scale setting method, or each position in the projection area S may be mapped into the image obtained by the scene capturing module 12.
The content processing module 13 is configured to perform light carving content creation according to the picture of the projection area S obtained by the scene capture module 12 as a template. For the projected object (S1, S2, S3, S4 \8230;) within the projection region S, an accurate geometric model is obtained by image processing. The geometric model may coincide fully or partially with the projected object and its specific location. For example, from the model projected in the projection region S, a geometric model of the face contour thereof is obtained, which may be a partial region in the entire head contour; the geometric model of the face outline is saved in the light carving interactive interface as an object, and the object can be presented as the geometric model of the face outline or the object name "model 1 face" S2'. For another example, a geometric model of the clothing outline is obtained according to the model projected in the projection area S, and the geometric model of the clothing outline is saved in the light carving interactive interface as an object, which may be represented as the geometric model of the clothing outline or the object name "model 1 clothing" S2". In addition, the geometric model of the background from which at least a part of the objects are removed is named "background", the geometric model of the background from which the objects are not removed is named "panorama", etc., and the like, and the invention is not limited thereto.
Preferably, when an image to be matched with an object is to be obtained, the image is processed by taking the object as a mask, so that the image is projected only on the projected object and does not exceed the range of the projected object. When more than one image is projected onto the projection target, for example, when a composite image is repeatedly formed from the same image, the composite image is processed using the target as a mask, and the composite image is projected within the range of the corresponding projection target. The images may also be dynamic video content. The plurality of objects may be respectively matched with the plurality of images, a canvas image may be generated by superimposing the positions of the objects on the canvas, and the canvas image may be sent to the projection module 11 and projected into the projection area S by the projection module 11.
The communication module 14 is used for establishing a wireless communication link with the mobile terminal 20 and the internet to perform data interaction with the mobile terminal 20 and the internet. Preferably, a two-dimensional code is used to facilitate the quick establishment of a wireless communication link between the mobile terminal 20 and the intelligent projection device 10. The communication module 14 may be a wireless hotspot, and the two-dimensional code corresponds to link information of the wireless hotspot. The communication module 14 may also be used to establish a wireless communication link with a WLAN (wireless local area network) and, via the WLAN network, with a mobile terminal 20 that also has access to the WLAN network. The invention is not limited thereto. The two-dimensional code can be displayed in the form of a planar real object, attached to or erected in or near the projection area S. The two-dimensional code can also be displayed by projection through the projection module 11 of the intelligent projection device 10.
The user may operate his/her mobile terminal 20 to scan the two-dimensional code, so as to establish a wireless communication link with the intelligent projection apparatus 10 and obtain the light carving interactive interface 21 from the intelligent projection apparatus 10. The mobile terminal 20 includes a communication module 22 for establishing a wireless communication link with the intelligent projection device 10, and the communication module 14 is described in detail herein. The light carving interactive interface 21 may be presented in a display screen of the mobile terminal 20, and may also be presented in a display screen of the content processing module 13. The light carving interactive interface 21 may be an application program (APP), an applet that does not need to be installed, or a web page, which is not limited by the invention. The light carving interactive interface 21 presented in the display screen of the mobile terminal 20 may be the same as or different from the light carving interactive interface presented in the display screen of the content processing module 13; preferably, the light carving interactive interface 21 presented in the display screen of the mobile terminal 20 includes a part of functions of the light carving interactive interface presented in the display screen of the content processing module 13, in other words, the light carving interactive interface presented in the display screen of the content processing module 13 has more functions, and the light carving interactive interface 21 presented in the display screen of the mobile terminal 20 may select an object established in the earlier stage without editing the function of the object, and select and match an image to be matched with the selected object.
After the mobile terminal 20 presents the light carving interactive interface 21, the user operates the light carving interactive interface 21 to obtain an object and a corresponding image which need to be newly projected, and matches the corresponding object with the image.
In the light carving interactive interface 21, the objects may be presented in the form of, but not limited to, geometric models and object names, wherein representations of a plurality of objects may be presented in the form of, but not limited to, drop-down lists, alternate selection lists, distribution graphs, and the like, and a user may perform switching and selection of the objects to be selected by dragging, sliding, clicking, and the like in the light carving interactive interface 21; in another embodiment, the user may also input the object name of the object (e.g., "model 1 clothes", "background"), or input the voice corresponding to the object name of the object (e.g., long press the voice input button in the interface and issue a voice indication "background").
The user can select a picture from a picture library in the light carving interactive interface 21, and the picture is stored in the intelligent projection device 10; preferably, the picture is presented in the form of a thumbnail in the light carving interactive interface 21, so as to reduce the burden of communication transmission and display. The user can also obtain the pictures stored in the mobile terminal 20 through guidance of the light carving interactive interface 21. The user may also obtain pictures in the internet via guidance of the light carving interactive interface 21, at which time it is necessary to download to the mobile terminal 20 or obtain a network link thereof in order to provide the intelligent projection device 10 for processing.
After the picture (or image) is selected, in a preferred embodiment, the light carving interactive interface 21 further includes an image setting interface for performing parameter setting on the selected image, including but not limited to: the size of the image, the number of the distributed images, the direction of inclination (or the angle of inclination) of the image, the direction of movement (or the angle of movement) of the image, and the like. After the picture to be projected is selected and processed in a default image processing mode, the problem that the size of the picture is not appropriate to the size of the geometric model of the object still exists, and at the moment, the picture can be adjusted by adjusting the size of the picture so as to achieve a better matching effect with the projected object. And the dynamic effect can be formed by setting the image distribution number, the inclination direction, the moving direction and the like in the geometric model range of the same object. For example, in a "panoramic" scene in which snowflakes are falling, the entire projection area S includes projected objects that are projectable dynamic snowflakes on each of the projected objects. As another example, a scene with snowflakes falling is superimposed on the "background", and other projection areas outside the respective projected objects are used as projected objects of dynamic snowflakes. For another example, an image of a dynamic flame is superimposed on the "campfire stack" to create a warm atmosphere effect in winter.
After the user operates the mobile terminal 20 to match the object with the corresponding image according to his will, the adjusted matching relationship may be sent to the intelligent projection apparatus 10, the intelligent projection apparatus 10 updates the canvas image based on the adjusted matching relationship, and projects the canvas image to the projection area S through the projection module 11, and the corresponding image is projected onto the corresponding projected object in the projection area S.
In a preferred embodiment, the light carving interactive interface 21 further includes a preset matching relationship for indicating the matching relationship between the preset object and the image, so as to conveniently provide a special projection effect with respect to the whole scene or a partial scene. The preset matching relations can be superposed with the matching relations of manual operation, so that richer and more convenient interaction modes are provided for users, and the interestingness of interaction between a viewer and a scene is increased.
In summary, the light carving projection method provided by the invention can obtain the light carving interactive interface through the mobile terminal of the user by scanning the two-dimensional code, and modify and control the content of the light carving projection, thereby increasing the interest of interaction between people and scenes.
The present invention has been described in relation to the above embodiments, which are only examples of the implementation of the present invention. It should be noted that the disclosed embodiments do not limit the scope of the invention. Rather, it is intended that all such modifications and variations be included within the spirit and scope of this invention.
