Problems solved by technology

In the process of tracking different images and data displays, it is very easy for doctors to miss key information related to patient signs
At present, in oral implant surgery, implant guide plates are mostly used. The problems of this technology include: the use of invasive marker nails is difficult for patients to accept; Paying attention to the display of the implanter navigation parameters on the screen not only needs to combine the two-dimensional images on the screen and the situation in the patient's mouth in real time in the mind, but also cannot pay attention to the operation area and the patient's intraoperative response at the same time, and there are certain risks.

Embodiment Construction

[0064] Such as figure 1 As shown, an augmented reality navigation method for oral implant surgery in an embodiment of the present invention includes the following steps:

[0065] S1. Obtain the image of the intraoral environment through the monocular camera set on the AR glasses, and apply the SLAM algorithm to the image to obtain the real scene in the mouth and the first pose of the real scene in the mouth under the monocular camera coordinate system;

[0066] S2. Register the fifth pose of the real scene in the mouth in the world coordinate system with the virtual information to be navigated to obtain the second pose of the virtual information to be navigated in the world coordinate system;

[0067] S3. After processing the first pose, the second pose, and the fifth pose through the preset coordinate transformation relationship, the third pose of the virtual information to be navigated in the projected subjective coordinate system is obtained, and the third pose The pose is...

Abstract

The invention relates to an oral implantation surgery augmented reality navigation method and system. To-be-navigated virtual information is projected on AR glasses in a virtuality and reality combination mode after a dentist wears the AR glasses, counterpoint display is directly carried out in an operation region in a three-dimensional mode, and the obtaining habit of human natural visual information is met; the dentist does not need to splice a two-dimensional screen image and the intraoral condition of a patient in the brain in real time, the dentist is assisted in carrying out a high-precision oral implantation surgery, the risk is low, an implantation guide plate, an invasive marking nail and the like do not need to be used, the patient cannot be injured, and the problems that the implantation guide plate is too large in machining error and size and the like do not exist.

Description

technical field [0001] The invention relates to the field of oral implant surgery, in particular to an augmented reality navigation method and system for oral implant surgery based on visual SLAM technology. Background technique [0002] Precision medicine and intelligent medicine are the main development directions in the field of international medical equipment in recent years. Over the past few decades, many of the major technological breakthroughs in medical devices have occurred in diagnostic imaging, such as the application of ultrasound, mammography, CT, MRI and other technologies. These technologies allow doctors to better diagnose and treat through images in the process of practicing medicine. Currently, medical imaging enables instant diagnosis. However, while medical equipment is rapidly changing towards precision medicine and smart medicine, the form of image presentation is basically the same as in the 1950s. Visual data is still presented on a 2D flat screen...
