Problems solved by technology

[0003] In traditional brain surgery, the doctor determines the location and size of the lesion by understanding the two-dimensional image of the patient. The effect of the operation largely depends on the doctor's experience, so it is impossible to accurately locate the lesion before the operation.
At the same time, during the operation, there are also difficulties in how to avoid important functional areas, nerves and blood vessels, and choose a suitable path to reach deep lesions

Embodiment Construction

[0021] The entire test platform consists of a bracket main body 1, a horizontal workbench 2, a projector 3, a binocular stereo vision camera 4, an auxiliary light source 5, and a height sensor 6. figure 1 shown.

[0022] The main body of the bracket 1 adopts a rectangular parallelepiped skeleton structure, which can be made of aluminum alloy or other materials. Its key feature is that the four columns can stand vertically on the ground plane, and its upper, lower and middle parts are all in a horizontal state;

[0023] In the central part of the upper part of the bracket main body 1, a beam-type fixing frame is arranged, and a projector 3 is fixedly installed. The key is to make the lens of the projector located in the center of the upper surface and project directly below;

[0024] On both sides of the projector 3, a binocular stereo vision camera 4 is respectively fixedly installed for image acquisition. The key is that the two cameras are shooting the horizontal workbench b...

Abstract

The invention relates to an augmented reality system experiment platform applied to robot assisting surgical navigation. The augmented reality system experiment platform comprises a support main body (1), a horizontal working platform (2), a projector (3), binocular stereo vision cameras (4), auxiliary light sources (5), a height sensor (6) and a head mold fixing frame arranged on the horizontal working platform (2) and capable of rotating along the axial direction. The support main body (1) is in a cuboid framework type structure. The projector (3) projecting towards a position below is fixedly arranged in the center of the upper portion of the support main body (1). The binocular stereo vision cameras (4) are symmetrically fixedly installed at two sides of the projector (3), and the interval can be adjusted. The auxiliary light sources (5) with angles and brightness capable of being adjusted are installed on four corners of the upper surface of a framework. The horizontal working platform (2) capable of moving upwards and downwards is installed at a horizontal position of the middle of the support main body (1). The height sensor (6) is fixed on a side stand column of the support main body (1), is connected with the horizontal working platform (2), and is used for measuring the height value of the side stand column.

Description

Technical field: [0001] The invention relates to an augmented reality system test platform applied to robot-assisted surgical navigation. Background technique: [0002] With the continuous advancement of computer and robot technology, surgical robots have achieved good clinical results in the medical field. In recent years, robotic and computer-assisted surgical techniques are gradually being applied to brain surgery, which requires relatively high precision. [0003] In traditional brain surgery, the doctor determines the location and size of the lesion by understanding the two-dimensional image of the patient. The effect of the operation largely depends on the doctor's experience, so it is impossible to accurately locate the lesion before the operation. . At the same time, during the operation, there are also difficulties in how to avoid important functional areas, nerves and blood vessels, and choose a suitable path to reach deep lesions. Robot-assisted surgery has sol...
