Abstract

The invention provides a system and a method for real-time three-dimensional measurement of key indexes in ear microsurgery, and relates to the technical field of computational microscopic imaging. The system comprises a double-viewpoint microscopic imaging unit which is used for generating microscopic image data with symmetrical structures of a middle ear and an inner ear in the to-be-measured microsurgery, a double-viewpoint microscopic image acquisition unit used for acquiring the microscopic image data, and a double-viewpoint microscopic image control and processing unit used for controlling shooting of the double-viewpoint microscopic image acquisition unit and processing acquired microscopic image data to obtain a quantification result of the index to be measured. The double-viewpoint microscopic image acquisition unit is connected with the double-viewpoint microscopic imaging unit, and the double-viewpoint microscopic image acquisition unit is connected with the double-viewpoint microscopic image control and processing unit; and according to the invention, accurate intelligent analysis processing is carried out through a microscopic imaging technology, and key complex indexes in the ear microsurgery field can be measured through non-contact measurement.

Description

technical field [0001] The invention relates to the technical field of computational microscopic imaging, in particular to a system and method for real-time three-dimensional measurement of key indicators in ear microsurgery. Background technique [0002] Microscopes are the most commonly used auxiliary medical equipment in otolaryngology, especially ear microsurgery. Thanks to the magnification of the surgical field by the microscope, doctors can perform more refined surgical treatments on patients with ear diseases. [0003] At present, doctors obtain information about the microscopic field mainly through vision, and the processing of microscopic image information completely depends on the human brain. These microscopic image information include cognitive identification of the operative field, intraoperative navigation planning, and intraoperative measurement. Among these information processing mechanisms, the information processing of intraoperative measurement by the hu...
