As shown in FIG. 1 , a method for generating a three-dimensional image is disclosed in the embodiment, including:

S101. Acquire a picture set of an item, where the picture set includes at least a start image, an intermediate image, and a last image;

S102. Sequencing the start image, the intermediate image, and the end image in sequence to obtain a three-dimensional image. image.

In this way, the images in the acquired image collection can be spliced, in particular, the starting image, the intermediate image and the last image in the image collection are sequentially spliced to form a three-dimensional image, thereby generating a three-dimensional image. The required equipment is less, the cost is lower, the material of the three-dimensional image is less required, the acquired three-dimensional image has a smaller amount of data, is convenient to use and share, and can quickly, conveniently, and cost-effectively synthesize three-dimensional images of articles of any size. . Image stitching technology is already a relatively mature technology. It has been applied in many softwares, such as PHOTOSHOP. As long as there are several related pictures, it can be automatically put together.

In this embodiment, the picture set may further include more images, for example, the intermediate image includes 10 images, 20 images, or 28 images, etc., so that the generated three-dimensional image is more realistic and close to reality. In this embodiment, the article can be photographed from various angles to obtain an image of the full angle of the article, so that the spliced three-dimensional image is more realistic. The initial image may be the first frame that was just taken, the end image may be the last frame of the shot, and the middle image may be one frame or multiple frames.

Specifically, the collection of pictures is obtained by taking a picture around the item one week. For example, the item can be placed in a fixed position and the camera can be photographed around the item one week. It is also possible to center the item to be photographed in a slowly rotating turntable, and then place the turntable together with the item into the small studio; then place the camera and the like in front of the studio with the shooting stand, and the lens is aimed at the item in the studio. According to the imaging of the items in the shooting interface, adjust the position of the camera so that the item to be photographed is in the middle of the shooting interface, let the camera lens focus on the item, and adjust the item to the appropriate size in the lens, and then perform continuous shooting. After one week, the shooting is completed, and a collection of pictures is obtained, including the start image and the end image, and an intermediate image between the start image and the end image. The number of intermediate images is related to the rotational speed of the turntable and the continuous shooting frequency of the camera. For example, you can set the carousel to turn around for about 25 seconds, and you can take 50 photos as an intermediate image. In this embodiment, a camera of a mobile terminal such as a mobile phone may be used for photographing, and then a step of synthesizing a three-dimensional image may be performed, or another camera may be used for photographing and then transmitted to another terminal for synthesizing.

In this embodiment, the step of taking a picture around the item one week specifically includes: continuously shooting the item rotated at a certain speed. In this way, it is more convenient to obtain an image of the item for one week, thereby obtaining images more quickly and splicing.

According to one of the examples, the step of sequentially splicing the start image, the intermediate image, and the end image further includes:

Obtaining an adjustment instruction for the stitched image and adjusting the image; wherein the adjustment instruction includes at least an instruction to adjust contrast, brightness, and saturation.

In this way, you can adjust the 3D image and preview the effect of the 3D image to see if the preview is satisfactory. If you are not satisfied, you will reacquire the image collection and stitch it again until you are satisfied. For example, you can re-shoot, or re-select the image for splicing, knowing that you are satisfied. Other parameters such as color, picture orientation adjustment, angle adjustment, and the like can also be adjusted in this embodiment.

According to another example, the method further comprises uploading the acquired three-dimensional image to a cloud server to cause the server to generate a uniform resource locator for output to the terminal.

This will upload to the cloud server, the server will automatically generate a URL (Uniform Resource Locator) for output to various platform terminals, the cloud server will generate a unique ID for each 3D photo of the item and the corresponding URL, which is used to embed 3D photos into various platforms, including PC-side web pages, mobile web pages, mobile app, WeChat public account, and can share to WeChat friends circle, WeChat friends, QQ space, QQ friends, and micro Bo et al; can be easily embedded into a variety of terminal platforms, so that the e-commerce industry's merchandise display effect is better, more attractive to consumers' desire to buy.
