Embodiment 1

[0109] refer to figure 1 As shown, in Embodiment 1 of the present invention, the specific flow of the image processing method is as follows:

[0110] Step 100: Acquire the image data of the user collected by the endoscope; wherein, the image data at least includes image data captured by the camera unit in the endoscope, and the type of the image data is a depth image; the The collected image data of the user indicates that splicing has not been performed.

[0111] Wherein, the endoscope is, for example, an oral cavity endoscope, and an imaging unit is arranged in the endoscope for taking images. One imaging unit or a plurality of imaging units may be arranged in the endoscope, and The type of image data obtained is a depth image, that is, an RGBD image, which is a three-dimensional true-color image, so that the three-dimensional information of the image can be obtained to facilitate subsequent three-dimensional image processing.

[0112] Preferably, the oral endoscope in the...

Embodiment 2

[0196] Based on the above examples, see image 3 As shown, in Embodiment 2 of the present invention, the specific flow of the updating method of the cloud server is as follows:

[0197] Step 300: Receive an update request sent by the terminal, wherein the update request includes at least: the user's three-dimensional image model, the number information of the recorded block whose mapping relationship with the spliced ​​image data block has been determined, and the spliced ​​image data block. Part or all of the image data blocks in the subsequent image data blocks except the image data blocks whose mapping relationship with the blocks in the saved 3D image frame database have been determined.

[0198] Wherein, the three-dimensional image frame database stores the image data of the blocks divided into the three-dimensional image frame image and the position information of the image of each block; the image data of the block includes: serial number information, image feature info...

Embodiment 3

[0209] Based on the above examples, see Figure 4 As shown, in Embodiment 3 of the present invention, the specific flow of the image processing method is as follows:

[0210] Step 400: Acquire the image data of the user collected by the endoscope; wherein, the image data at least includes image data captured by the camera unit in the endoscope, and the type of the image data is a depth image; the The collected image data of the user indicates that splicing has not been performed.

[0211] Step 410: Splicing the image data and the image data and the saved image data block to obtain a spliced ​​image data block, wherein the image data block includes at least one image data.

[0212] Further, before step 410 is performed, the method further includes: determining that the number of the image data is greater than a preset threshold.

[0213] In this way, the splicing and subsequent processing are performed only when the number of image data acquired accumulatively reaches a certa...

Abstract

The invention relates to the field of image processing, and in particular relates to an image processing method and device. The method comprises the steps that image data are acquired and spliced to acquire spliced image data blocks; an image data block containing the image data in the spliced image data blocks matches the image of a block in a three-dimensional image frame database; if at least one mapping relationship is acquired, the three-dimensional image model of a user is updated and displayed according to a first preset display policy; if the spliced image data blocks do not acquire the mapping relationship, displaying is carried out according to a second preset display policy; if a preset condition is satisfied, the three-dimensional image model of the user, the recorded number information of the determined block which acquires the mapping relationship and / or the image data blocks which do not acquire the mapping relationship are uploaded to a cloud server; the cloud server updates the three-dimensional image frame database; a three-dimensional image is acquired without continuously and sequentially scanning an oral cavity; and the three-dimensional image frame database iscontinuously improved to improve the matching success rate.

Description

technical field [0001] The present invention relates to the field of image processing, in particular to an image processing method and device. Background technique [0002] The traditional intraoral speculum is a device used for dental optical impression taking. When using it, the optical tip for taking the impression needs to be moved in an orderly manner between the upper and lower dentition of the user. It does not support the scanning tip in the oral cavity. Random roaming within the network is very professional, and the user interaction effect is poor, so professionals are required to operate. [0003] At present, a kind of self-service intraoral speculum has also appeared. The user holds this device, puts the camera part into the oral cavity, and rotates the camera to perform an endoscopic view of the oral cavity. However, the endoscopic image can only see a small part at a time. Although the picture of the teeth can also be seen, it is difficult to confirm which toot...
