Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The embodiment of the invention discloses a projection control method, the flow of which is shown in figure 1, comprising the following steps:
step S101: obtaining a holographic projection image, and generating a coordinate system corresponding to the holographic projection image, wherein each coordinate axis of the coordinate system corresponds to at least one attribute of the holographic projection image;
after obtaining the holographic projection image, the properties of the holographic projection image, such as size, brightness, etc., are analyzed. When generating the coordinate system, each coordinate axis is assigned to at least one property of the holographic projection image. The coordinate axes and the attributes of the hologram projection image may be in a one-to-one correspondence relationship or in a one-to-many relationship, that is, one coordinate axis corresponds to two or three attributes.
Coordinate axes on the coordinate system have a certain proportional relationship with the corresponding attributes. The proportional relationship is generated in advance when the coordinate system is generated, and specifically, the adjustable range of each coordinate axis and the adjustable range of the corresponding attribute have a first proportional relationship. For example, as shown in fig. 2, the coordinate system is a two-dimensional coordinate system, in which the adjustable range of the X coordinate axis is-10 to 10cm, the image size is corresponding to the adjustable range, the adjustable range of the size is-10 to 10 times, wherein a positive value represents a multiple of enlarging to an original size, a negative value represents a multiple of reducing to the original size, the unit variable on the coordinate axis is 1cm, and the corresponding adjustment amount is 1 time. If the adjustment range of the size is-20 to 20 times, the size adjustment amount corresponding to a unit variable of 1cm of the coordinate axis is 2 times. It can be seen that the unit variable of each coordinate axis has a certain proportional relationship with the unit variation of a certain attribute of the hologram projection image. The proportional relationship can be set according to actual conditions.
When one coordinate axis corresponds to a plurality of attributes, for example, one coordinate axis corresponds to a size and a brightness. The unit variables of the coordinate axis correspond to the unit variation of the size and the unit variation of the brightness, respectively.
Step S102: projecting the coordinate system in a projection space by a projection device;
the coordinate system is also projected by a projection device. So that the user can operate it in the projection space.
Step S103: identifying a first operation of a target object aiming at the coordinate system, and determining a control instruction corresponding to the first operation;
the target object in the present application may be a finger of a person, or a component having a control function. Such as a projector pen, etc.
Step S104: and executing the control instruction to process the holographic projection image.
The control instruction is obtained by identifying a first operation on the coordinate system, and then the image is processed.
The projection control method disclosed in the embodiment of the application realizes the processing of the holographic projection image correspondingly through the operation on the coordinate system having the corresponding relation with the holographic projection image. When the user operates the coordinate system, the adjustment range can be visually seen, and further the adjustment of the holographic projection image can be correspondingly realized, so that in the control process of the holographic projection image, the processing mode and the processing quantity value of the image can be correspondingly obtained through the operation of the coordinate system, and further more accurate operation of the holographic projection image can be realized.
Preferably, in the above embodiment, one holographic projection image may correspond to only one coordinate system, and the overall control of the holographic projection image is realized through the coordinate system. The holographic projection image can also be divided into N holographic projection sub-images, each of which is controlled by a coordinate system. Or, a coordinate system is generated for each holographic projection sub-image, that is, M coordinate systems corresponding to the N holographic projection sub-images are generated, where M and N are greater than or equal to 1, M is less than or equal to N, and M and N are positive integers.
When processing an image, the processing of the image can be realized by only defining the holographic projection sub-image to be processed and the corresponding coordinate system.
Further, if the attributes of the hologram projection images are more and the coordinate axis of one coordinate system cannot be controlled better, a plurality of corresponding coordinate systems can be generated for each hologram projection image or hologram projection sub-image.
Preferably, in the above embodiment, the generated coordinate system may be displayed in the projection space in superposition with the holographic projection pattern. The coordinate system can be preset to be hidden, and when the display is needed, the coordinate system can be displayed by clicking any position on the holographic projection image or clicking a specific editing button. In the display mode, the coordinate system does not need to occupy extra projection space, so that the display effect of the holographic projection image is not influenced on the premise of not increasing the projection space.
Alternatively, the projection space may be divided into two regions, a first projection region and a second projection region. And displaying the holographic projection image and the coordinate system in a first projection area and a second projection area of the projection space respectively. This embodiment has the advantage that the coordinate system is displayed separately from the holographic projection image, controlled independently, avoiding erroneous operation.
Preferably, the process of identifying the first operation of the target object with respect to the coordinate system is as shown in fig. 3, and includes:
step S301: acquiring the position of the target object;
the target object may be a position pointed by a finger of the user or a landing position of a laser light emitted from the projector pen. If a finger is used, a camera or an infrared sensor can be used for recognizing the used gesture.
Step S302: prompting to enter an editing mode when the target object is located in a preset editing area;
the preset editing area may be an area of a preset editing button, or an area where each coordinate system is located. If the target object falls in the above-mentioned area, that is, if image processing is to be performed, the user is prompted to enter an editing mode, and editing can be performed. The prompting mode may be that a cursor on a coordinate axis flickers at a current position, or a prompt tone is sent out by using a projection device or other devices.
The current position in this embodiment may be a predefined initial position of the cursor, or may be a position where the cursor is automatically positioned on a coordinate axis corresponding to the current attribute value of the image.
Step S303: under the editing mode, identifying the moving track of the target object on a target coordinate system;
upon entering the editing mode, the user starts operating on the target coordinate system. The target coordinate system is a coordinate system operated by the user, and when a plurality of coordinate systems exist, the coordinate system actually operated by the user is the target coordinate system.
The movement trajectory may be a movement of the user's finger on the coordinate axes of the target coordinate system, as shown in fig. 4, from a point having coordinates (1, 0) to a point having coordinates (6, 0). Alternatively, the user's finger may first click on a position on the coordinate axis and then click on a position. According to the sequence of the two positions being clicked successively, the motion trajectory is determined, as shown in fig. 5, the point with the coordinate (1, 0) is clicked first, and then the point with the coordinate (6, 0) is clicked.
Step S304: and identifying a first operation of the target object according to the movement track.
A first operation of a target object is determined.
Preferably, a process of the first operation of identifying the target object according to the movement track is as shown in fig. 6:
step S601: acquiring a target coordinate axis corresponding to the moving track;
it is determined on which coordinate axis the target object is operated.
Step S602: acquiring a target moving distance and a moving direction corresponding to the moving track;
the direction of movement is determined, as well as the distance of movement.
Step S603: according to the target coordinate axis, the target movement distance and the movement direction, determining that the first operation is: and moving the target moving distance along the moving direction on the target coordinate axis.
For example, the process may determine that an operation is moving 2cm from left to right on the X-axis.
Further, determining that the control instruction corresponding to the first operation is shown in fig. 7 includes:
step S701: acquiring the attribute of the holographic projection image corresponding to the target coordinate axis;
as shown in fig. 2, the X-axis represents the size of the hologram projection image.
Step S702: determining an attribute adjustment value corresponding to the target moving distance according to the first proportional relation;
referring to fig. 2, assuming that its real position is (0,0) and its end position is (0,2), it means that the size of the hologram projection image is adjusted by 2 times, but it cannot be determined whether to enlarge or reduce.
Step S703: determining the attribute adjusting mode according to the moving direction;
in this embodiment, the zoom-in is assumed to be performed by zooming in from left to right and zooming out from right to left.
Step S704: determining that the control instruction corresponding to the first operation is: and adjusting the attributes of the holographic projection sub-images corresponding to the target coordinate system according to the attribute adjustment mode and the attribute adjustment value.
And finally, adjusting the size of the holographic projection sub-image corresponding to the target coordinate system to be enlarged to 2 times of the original value.
In this embodiment, if the target coordinate system corresponds to a complete holographic projection image, the corresponding holographic projection sub-image is itself. If the target coordinate system corresponds to a holographic projection image comprising a plurality of holographic projection sub-images, and all holographic projection sub-images correspond to the target coordinate system, the adjusted image is actually the holographic projection image itself. If the target coordinate system corresponds to one or several holographic projection sub-images, the holographic projection sub-images are adjusted instead of the whole image, so that the effect of local magnification can be achieved. Convenient for the user to observe.
In the projection control methods disclosed in the above embodiments, the analysis is performed based on the angle from which the user operates the coordinate system to reverse the adjustment of the image. Alternatively, the application may also select the image to be adjusted first, and then operate on the corresponding target coordinate system. As shown in fig. 8, the process includes:
step S801: receiving a holographic projection image selection instruction;
step S802: determining a holographic projection sub-image to be adjusted and a target coordinate system corresponding to the holographic projection sub-image to be adjusted according to the selection instruction;
step S803: acquiring the position of the target object;
step S804: prompting to enter an editing mode when the target object is located in a preset editing area;
step S805: under the editing mode, identifying the moving track of the target object on a target coordinate system;
step S806: and identifying a first operation of the target object according to the movement track.
In the method disclosed in the embodiment of the present application, the holographic projection sub-image to be adjusted is determined according to the selection of the user, and assuming that the user selects the entire holographic projection image, it means that the user selects all the holographic projection sub-images as the holographic projection sub-images to be adjusted. If one or some of them are selected as holographic projection sub-images to be adjusted.
The selection process may be to double click a certain holographic projection sub-image, or to long-press a certain area so that each holographic projection sub-image is in a state of being selectable, and select the holographic projection sub-image to be adjusted by way of checking, clicking or selecting a frame. The corresponding target coordinate system is then determined.
After this step, the first operation of identifying the target object according to the movement track may refer to the embodiment shown in fig. 6. The process of determining the control command corresponding to the first operation may refer to the embodiment shown in fig. 7, except that, in step S704, the holographic projection sub-image to be adjusted is directly adjusted, and the target coordinate system does not need to be searched.
Compared with the method for determining the holographic projection sub-image by using the target coordinate system, the method disclosed by the embodiment of the application is more visual and convenient, and better accords with the processing thought of the image.
Preferably, in the two embodiments, if the target coordinate system is obtained first, and then the corresponding holographic projection sub-image is obtained, in the actual display process, if the target coordinate system is selected, then the corresponding holographic projection sub-image may be identified in the holographic projection sub-image. The identification may be performed in such a way that the edge of the holographic projection sub-image is emphasized in color to be highlighted, or the holographic projection sub-image is highlighted above the other holographic projection sub-images, or the other holographic projection sub-images are hidden or displayed in a semi-transparent manner, so that it can be visually seen which holographic projection sub-image corresponds. The target coordinate system may be processed in the above-described processing manner so as to be distinguished from other target coordinate systems.
If the holographic projection sub-image to be adjusted is selected first and then the target coordinate system is determined, the holographic projection sub-image and the target coordinate system can be highlighted by referring to the above mode.
