Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Referring to fig. 1, fig. 1 is a schematic flow chart illustrating a labeling method for an image mosaic wall according to the present invention.
The method for labeling the image mosaic wall in the embodiment can comprise the following steps of:
s11: and acquiring a moving track and an annotation operation formed by the annotation operation equipment on the image generation equipment.
The image generation device is provided with image generation software, and is an intelligent device with image acquisition, image generation and image output functions, wherein the image generation device can be a computer (such as a computer) with a display screen and image generation software or an embedded device, and can be connected with a labeling operation device. The window of the image generation device forming the annotation operation may be a window of running image generation software, and may specifically be a full-screen window of the image generation software. The size of the full screen window of the image generation software may coincide with the size of the window of the image generation device (the entire display screen window of the image generation device). The adopted image generating equipment can be processing equipment independent of each signal source equipment and is not limited by each signal source equipment and each signal window.
The labeling operation device is a device capable of realizing a labeling operation function, and specifically may be a mouse, such as a wireless mouse, or a touch pad on a notebook computer, and realizes the labeling operation by user touch. A receiver of the annotation operating device (e.g., a receiver of a wireless mouse) is mounted on the image generating device so that the image generating device can receive the movement trajectory of the annotation operating device and the annotation operation.
S12: and generating an annotation image on a window of the image generation equipment according to the moving track and the annotation operation.
In one embodiment, the movement track and the labeling operation are performed by generating a labeled image on a window of the image generation device in real time, and then mapping the window containing the labeled image to the top layer of each signal window of the image mosaic wall in real time.
The movement track can be acquired by acquiring the position coordinates of the marking operation equipment when the marking operation equipment moves. For example, when the mouse moves, the moving track of the mouse is recorded as a continuous image shot at a high speed on the image generation device, and meanwhile, the annotated image is generated on the image generation software window in combination with annotation operation, such as highlighting, drawing and other annotation operation. As shown in fig. 2, the annotation image is a curved line segment at about the center of the window of the notebook computer 200, the mouse 300 is connected to the notebook computer 200, and the curved line segment mapped on the image mosaic wall 300 in the subsequent step is also at about the center of the top layer of the two signal windows.
The window of the image generation device may be displayed in full screen background color without additional menus. When an annotation image is generated on a window of an image generation apparatus, the background color of the window of the image generation apparatus is set to be different from the color of the annotation image. Specifically, the annotation image is generated on the background color of the window of the image generation software, and then the color of the annotation image is not consistent with the background color of the window of the image generation software. The background color is a color different from the color of the annotation image, for example, white can be selected as the background color, and the color of the annotation image can be various other colors than white, for example, yellow.
The annotation image can be generated in a manner triggered by the annotation operating device. For example, pressing the left button of the mouse triggers generation of the annotation image.
In one embodiment, the step of acquiring the movement track and the annotation operation formed by the annotation operation device on the image generation device comprises the following steps:
acquiring a trigger instruction input by a user to the marking operation equipment;
and recording the moving track and the color of the labeling operation according to the triggering instruction to generate a labeling image.
After the steps are executed, because the annotated image is generated on the window of the image generation device, the annotated image can be mapped on the image splicing wall, and the annotation behavior of the image generation device and the annotation behavior on the image splicing wall can be synchronized as far as possible in real time.
In one embodiment, on a window of the image generation device, the step of generating the annotation image by the movement track and the annotation operation comprises the following steps:
acquiring an erasing instruction input by the marking operation equipment;
and erasing the annotation image generated on the window of the image generation device according to the erasing instruction.
After the steps are executed, because the annotation image on the window of the image generation equipment is erased, the annotation image mapped on the image splicing wall is also erased, and the annotation behavior of the image generation equipment and the annotation behavior on the image splicing wall can be synchronized in real time as far as possible.
S13: and mapping the window containing the marked image to the top layer of each signal window of the image splicing wall, and marking each signal window on the image splicing wall by using the marked image.
In order to better label each channel of signal window of the spliced wall, and not to shield the content of each channel of signal window, before step S13, the background color of the window generating the labeled image needs to be removed. Specifically, the background color can be removed in a matting way. And after removing the background color of the window for generating the marked image, only the marked image is left on the top layer of each signal window of the image splicing wall.
The image mosaic wall is connected to a plurality of signal source devices, as shown in fig. 2, the image mosaic wall 100 is connected to two DVD player devices, so that there are two signal windows. The window without the background color and the labeled image are mapped on the top layers of the two signal windows, so that the labeling operation equipment of the mouse 300 can label any signal window at any position on the whole wall.
In one embodiment, the step of mapping the window containing the annotated image to the top layer of each signal window of the image mosaic wall is mapping to the top layer of each signal window of the image mosaic wall in real time.
In one embodiment, the step of mapping the window containing the annotated image to the top layer of each signal window of the image mosaic wall includes:
and setting the window where the top layer is located as a full-screen window of the image splicing wall so as to cover each signal window and label the signal windows at any positions of the splicing wall.
The mapping means that the two elements have a one-to-one correspondence relationship, and when the annotation image is mapped, the position of the annotation image in the window of the image annotation equipment and the position of the annotation image in the window of the image splicing wall are in one-to-one correspondence, so that when the annotation operation equipment is moved, the annotation image of the window of the image annotation equipment and the annotation image of the window of the image splicing wall can be kept synchronous, the annotation is smooth, and the hysteresis feeling can not be generated.
The actual image splicing wall is large in wall body and is often connected with a plurality of signal source devices, such as a DVD and a computer, so that a plurality of paths of signal windows are often displayed simultaneously on the image splicing wall, and in order to label any signal window at any position of the image splicing wall, a full-screen window containing a labeled image needs to be opened at the top layer of each path of signal window. The annotated image starts from the image generation device, and the window size of the image generation device is not equal to the full-screen window size of the image mosaic wall, so the size of the window of the image generation device containing the annotated image to be mapped needs to be enlarged to the full-screen window size of the image mosaic wall (the window of the whole liquid crystal screen of the image mosaic wall).
In one embodiment, the step of mapping the window containing the annotation image to the top layer of each signal window of the image mosaic wall comprises the following steps:
acquiring the size of a full-screen window of an image splicing wall;
and amplifying the window for generating the marked image, wherein the size of the amplified window is consistent with the size of a full-screen window of the image splicing wall. The window for generating the annotation image may be a full-screen window of the image generation software, and the size of the full-screen window may be equal to the size of the whole liquid crystal screen of the image generation device.
Since the size of the window containing the annotated image is to be enlarged to the size of the full-screen window of the image mosaic wall, in order to achieve the equal-scale enlargement, in one embodiment, the output resolution aspect ratio of the image generation device is consistent with the aspect ratio of the full-screen window of the image mosaic wall. For example, the actual display ratio of a full screen window of an image mosaic wall is 4:3, and the aspect ratio of the output resolution of the image generation device must also be 4: 3. Therefore, when the image splicing wall is opened to be a full-screen window, the extracted window is amplified in equal proportion when being amplified, so that the mapping of the marked image is facilitated, and the marking operation is not influenced. In another embodiment, the aspect ratio of the window, which may also be image generation software, is the same as the aspect ratio of the full screen window of the image mosaic wall.
According to the method for marking the image splicing wall, the marked image is generated on the window of the image generation equipment, the marked image is mapped to the top layer of each signal window of the image splicing wall, marking operation is performed on the window of the image generation equipment, accordingly, marking operation on each signal window of the image splicing wall can be achieved, and data of a signal source can be better displayed on the image splicing wall.
