Problems solved by technology

[0004] The panorama mosaic technology provided by the existing technology can only realize the mosaic of two-dimensional images. With the increasing requirements of users, this technology cannot achieve the purpose of stitching three-dimensional images that users want, and thus cannot satisfy users to obtain panoramic three-dimensional images. Stereoscopic Image Requirements
Furthermore, this prior art is an image post-processing process, and the user cannot know exactly whether the scene is enough to be photographed or covered, and can only know the effect of the panoramic image after capturing all the images; for splicing, If there is no overlapping area between the original images during the stitching process, there will be a groove in the final panoramic image, and this groove can only be seen at the end, which will cause the user to re-shoot the scene and re-stitch it, which is time-consuming It is laborious; and the splicing effect is not good due to shooting or technical reasons during splicing, and cannot be corrected at any time, splicing at any time, which brings regret to the user experience

Embodiment 1

[0062] The embodiment of the present invention provides a method for realizing the real-time preview of the panoramic image. For the convenience of description, the embodiment of the present invention takes the user wishing to obtain a panoramic three-dimensional image as an example. Refer to image 3 , the content is as follows:

[0063] 101: Acquire a 2D image of the first scene through a ranging camera according to user requirements.

[0064] In this embodiment, it is assumed that the user uses a ranging camera, and accordingly, the user can obtain a two-dimensional image of the first scene through the ranging camera according to the user's hobbies and other demands. see Figure 4 , is a schematic diagram of a ranging camera provided by an embodiment of the present invention, wherein the ranging camera includes at least two parts: Figure 4 As shown, A represents a color camera for shooting two-dimensional images; B represents a distance measuring instrument for measuring...

Embodiment 2

[0111] The above-mentioned embodiment 1 is described by taking the ranging camera (or depth camera) as an example. Different from the method of acquiring depth information through the ranging camera (or depth camera) provided in Embodiment 1, the embodiment of the present invention provides a method based on The method that binocular camera realizes the real-time preview of panoramic image, see Figure 5 , the content is as follows:

[0112] 201: According to the needs of the user, for the first scene, obtain the left image and the right image of the scene by shooting respectively through the left lens and the right lens of the binocular camera.

[0113] In order to facilitate the description, this embodiment takes the user to use a binocular camera to shoot as an example. The working principle of the binocular camera is to use two independent cameras to simulate the human eyes to perform three-dimensional image imaging. For a certain scene, through binocular The left camera ...

Embodiment 3

[0141] The above-mentioned embodiment 2 is described by taking the binocular camera as an example. In actual implementation, the user can also realize the real-time preview of the panoramic image through the simplest monocular camera. Correspondingly, the embodiment of the present invention provides a The method for realizing the real-time preview of the panoramic image by the camera, see Figure 8 , the content is as follows:

[0142] Step 301: For the first scene, the user shoots the scene at position A through a monocular camera.

[0143] Step 302: Move the monocular camera from position A to position B, and shoot the scene at position B again through the monocular camera.

[0144] Among them, see Figure 9 , when the method for realizing the real-time preview of the panoramic image based on the monocular camera provided by the embodiment of the present invention, the schematic diagram of the movement of the monocular camera when shooting a certain scene, as shown in Fi...

Abstract

The invention discloses a method and a device for realizing real-time viewing of panoramic pictures, belonging to the field of electronics. The method comprises the following steps: two-dimensional images of the current scene are obtained; a depth map of the two-dimensional images is obtained; pre-stitching is carried out according to the two-dimensional images of the current scene, the two-dimensional images of the last scene of the current scene, the depth map of two-dimensional images of the current scene and the depth map of two-dimensional images of last scene of the current scene to generate and display pre-stitched panoroma three-dimensional images; when confirmation information from the users is received, the broad-viewing three-dimensional images are stitched and the three-dimensional images of the last scene of the current scene are continuously obtained until the panoramic three-dimensional images are obtained; in the invention images, especially the three-dimensional images are stitched in real time, displayed in real time and previewed in real time, so that panoramic images appear wherever the camera aperture goes and image-stitching mistakes can be corrected anytime, thus improving user experience.

Description

technical field [0001] The invention relates to the electronic field, in particular to a method and device for realizing real-time preview of panoramic images. Background technique [0002] With the rapid development of digital imaging technology, digital imaging equipment has been more and more widely used. However, due to the limitations of digital imaging equipment itself, the field of view width of digital images and videos cannot meet the application requirements of wide-angle images or even panoramic images desired by users. In order to create seamless wide-angle images, people use hardware-oriented methods (such as anti-refraction systems, fisheye lenses, etc.), and use newly added hardware-assisted digital imaging equipment to obtain wide-angle images. Capturing as much information as possible on a limited imaging surface can lead to severe distortion of the image. The prior art also provides a digital mosaic image technology, which can intelligently establish a wi...
