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...

The present invention relates to an augmented reality navigation method and system for oral implant surgery. After wearing AR glasses, the dentist projects virtual information to be navigated on the AR glasses in a combination of virtual and real, and directly aligns and displays them in the operation area in a three-dimensional form. It conforms to human’s natural visual information acquisition habits, and the dentist does not need to combine the two-dimensional images on the screen with the situation in the patient’s mouth in real time in his mind, assisting the dentist to perform high-precision oral implant surgery, with low risk, and no need to use implant guides, invasive Sign nails, etc., will not cause damage to the patient, and there will be no problems such as processing errors and excessive volume of the implant guide plate.
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...
