detailed description

The technical solutions in the embodiments of the present invention are clearly and completely described in the following with reference to the accompanying drawings in the embodiments of the present invention. It is obvious that the described embodiments are only a part of the embodiments of the present invention, but not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention.

The embodiment of the invention provides an image mosaic method and device, which are applied to a wearable projection device, and are respectively described below. First, an image mosaic method will be described.

It should be noted that the wearable projection device may be a wristband worn on a wrist, a watch, or the like, or may be a pair of glasses worn on the head. The wearing portion of the wearable projection device is not limited in the present invention. In the embodiment provided by the present invention, the wearable projection device worn on the wrist is mainly taken as an example, and is hereinafter referred to as "wrist throwing device".

As shown in FIG. 1 , an embodiment of the present invention provides an image mosaic method, which includes the following steps:

S101. Determine a wearable projection device for performing image stitching.

Since the present invention uses a plurality of wrist-pitch devices to splicing a panoramic image, the wrist-pitch device storing the image to be stitched can be used as the main wrist-casting device before splicing, and the main wrist-casting device is used as the execution of the method. main body.

The main wrist-casting device can first establish a communication connection with other wrist-operating devices. After the connection, the wrist-casting device participating in the image stitching is determined. It should be noted that the determined projection device may include the main wrist-casting device itself, or may not include .

Specifically, on the premise that all the wrist-casting devices (including the main wrist-casting device) have the WiFi-Direct function enabled, the main wrist-casting device searches for the surrounding wrist-pitching device and connects through the WiFi-Direct, and after the connection, the main wrist casts The device can establish a WiFi-Direct group, and the members of the group can include only the other wrist-pushing devices around the successfully connected main wrist-casting device, and can also include the main wrist-casting device itself.

In actual applications, the wearer of the main wrist cast device can activate the WiFi-Direct function by raising the arm.

Specifically, the above WiFi-Direct function is a communication technology that allows devices in a wireless network to connect to each other without using a wireless router. Typically, WiFi-Direct devices establish connections through a teaming group (in one-to-one or one-to-many topology). One of the WiFi-Direct devices is responsible for the entire team, including controlling which devices join, when the team starts and terminates, and so on. This device is an access point for traditional client devices and provides some of the services provided by the infrastructure access point.

S102, according to the determined number of projection devices, the image to be stitched stored by itself is divided into the number of sub-images, wherein the number is not less than 2;

The determined number of projection devices is the number of projection devices participating in the projection.

Specifically, when the main wrist device is connected with other surrounding wrist devices through the WiFi-Direct function, the determined number of projection devices is the number of members in the WiFi-Direct group in step S101, and the present invention is used for convenience of description. In the provided embodiment, the number can be represented by N, N being an integer, and N ≥ 2.

The main wrist shooting device can use the image processing software to segment the image to be spliced stored by itself into N sub-images, and the divided sub-images can be any shape.

S103. The corresponding number of sub-images are correspondingly shared to the determined each projection device, so that the determined projection device respectively projects the respective sub-images, and then the image to be stitched is spliced.

It should be noted that the object of “sharing” in this step may be the main wrist device itself, or other projection device that does not include the main wrist device itself.

When the shared object is not the main wrist device itself but other projection devices, the main wrist device can share the sub image to the determined wrist device by active sending, or can be determined by each wrist device. Actively obtain sub-images from the main wrist-casting device for sharing purposes.

Specifically, when the main wrist device itself is not included in the WiFi-Direct group member, the N sub-images are correspondingly shared to the N other projection devices, so that the N other projection devices respectively project the respective sub-images onto the projection screen. And splicing out the image to be stitched;

When the WiFi-Direct team member includes the main wrist device itself, the N-1 images in the N sub-images are shared to N-1 other projection devices, and the remaining sub-images are retained in the main wrist. The device is cast on the device so that the main wrist device and the N-1 other wrist device can project the corresponding sub-image onto the projection screen to splicing the image to be stitched.

The image splicing method shown in FIG. 1 can completely project a large panoramic image by splicing, which satisfies the requirement of the user to simultaneously view the entire content of a large panoramic image, thereby improving the user experience. . Moreover, compared with the conventional projection device, the wearable projection device is compact and portable, and its projection position can be flexibly set to meet the needs of the user to simultaneously view the entire contents of a large panoramic image at any time and anywhere.

Since the size of the sub-image projected by the wrist-casting device is related to the distance of the wrist-casting device from the projection screen, when the wrist-casting device is closer to the projection screen, the size of the projected sub-image is smaller, when the wrist-casting device is away from the distance When the projection screen is far away, the projected sub-image has a larger size.

Therefore, when the determined resolutions of the corresponding sub-images received by the respective wrist-pitch devices are the same, that is, when the main wrist-casting device divides the image to be stitched and directly shares the determined projection devices, only the determined When the distance between each projection device and the projection screen is the same, the complete image to be spliced can be spliced. Otherwise, the size of the portions where the sub-images are connected to each other is inconsistent, and the image to be spliced cannot be spliced.

However, in many cases, since the positions of the wearers of the wrist-worn devices are different, the distances of the determined wrist-pitch devices from the projection screen are also different.

In order to solve the above problem, preferably, based on the embodiment shown in FIG. 1, the method may further include: adjusting a resolution of a corresponding sub-image of the number of sub-images.

Specifically, the resolution of the corresponding sub-image may be adjusted according to the determined distance between each wrist-projection device and the projection screen, so that each projection device that receives the corresponding sub-image does not adjust its distance from the projection screen. Under the premise, the image to be stitched is stitched out by projection.

Alternatively, in order to solve the above problem, preferably, based on the embodiment shown in FIG. 1, the method may further include: adjusting a resolution of at least one of the plurality of sub-images.

Specifically, the resolution of at least one of the plurality of sub-images may be arbitrarily adjusted, so that each wrist-pitch device that receives the corresponding sub-image performs the distance between itself and the projection screen according to the resolution of the sub-image. After the adjustment, the corresponding sub-image is projected to splicing the image to be stitched.

The above resolution is adjusted by adjusting the resolution of the sub-images according to the resolution of the received sub-images The scheme of adjusting the projection distance between itself and the projection screen can increase the flexibility of determining the position of each wrist projection device when the user is required to simultaneously view the entire content of a large panoramic image, so that the wrist The device wearer can project at any time and place, making image stitching more convenient.

In addition, it should be noted that the image splicing method provided by the embodiment of the present invention can display the entire content of a large panoramic image to the viewer through splicing, and is also very interesting, for example, participating in image splicing. The wrist-worn device can adjust its own projection distance according to the resolution of the received sub-image, and splicing a complete image with the cooperation of several wrist-casting devices. Therefore, the image stitching method provided by the embodiment of the present invention can also be used for games to enrich people's spare time.

S202. Share the number of sub-images to the determined projection device that matches the sub-image name, so that the determined projection device respectively projects each sub-image, and then splices the image to be spliced.

Specifically, the main wrist cast device can share the N pieces of sub-images to the respective projection devices whose names correspond to each other. For example, a sub-image named "1" is shared with a projection device named "ASU_1", a sub-image named "2" is shared with a projection device named "ASU_2", and so on, until All of the N sheets of images are shared to the corresponding projection device.

It should be noted that when the determined projection device includes the main wrist cast device, the main wrist cast device is named according to the same method, and the sub image matching the main wrist cast device name is retained on the main wrist cast device. In order to enable the main wrist device to participate in image stitching.

First, when the main wrist device monitors the action of the wearer raising the arm, the communication connection with other wrist device is activated again, for example, the WiFi-Direct function is activated. Then, when the first preset action of the wearer is monitored, the number of sub-images are correspondingly shared to the determined respective projection devices.

Specifically, when the wearable projection device is a wrist throwing device, the first preset action may be an action of the wearer's shaking arm; when the wearable projection device is the glasses, the first preset action may be the wearer's Blinking action. For example, when the main wrist throwing device monitors the action of the wearer shaking the arm, the currently displayed sub image is sent, and the next sub image is switched, and for the N sub-images, when the motion of the shaking arm is detected N times, the sharing is considered The process ends.

Correspondingly, the image splicing method provided by any one of the above embodiments may further include: receiving an image sharing success confirmation message sent by the determined projection device after monitoring the second preset action of the wearer, so that the main wrist device is Know if the sharing of sub-images is successful.

Specifically, the wearer of the wrist-worn device that receives the sub-image can also activate the WiFi-Direct by lifting the arm, and confirm the reception of the corresponding sub-image by shaking the arm. At this time, the action of shaking the arm is the second preset action.
