The invention relates to the field of neuroscience experiments and biomedical engineering, and discloses a brain stereotactic method and system based on a turtle skull zero point, and the method comprises the following steps: taking a repeatedly recognizable bony mark point of a turtle skull as a zero point; a plane parallel to the reference plane of the brain stereotaxic instrument is established as an XY plane, and an axis parallel to the zero point probe is taken as a Z axis. Further, the invention provides a coordinate conversion method for converting target point coordinates in a three-dimensional image into a coordinate system of a stereotaxic instrument, which comprises the following steps of: positioning a zero point and a reference point in the image, determining a Z-axis direction, constructing an orthogonal coordinate base, and calculating rigid body transformation from an image coordinate system to a stereotaxic coordinate system; therefore, the three-dimensional displacement, the needle inserting depth and the track parameters for the movement of the positioning arm are output. The device can be used in cooperation with an existing brain stereotaxic instrument suitable for turtles, high-repeatability positioning of turtle brain region electrode implantation / injection is achieved, and the consistency and efficiency of cross-individual and cross-batch experiments are improved.

This invention relates to the field of ear rod technology, providing an endoscopic visualization stereotactic brain positioning ear rod, comprising a base plate, an ear rod shell, and an electronic display. The ear rod shell is located on one side of the top of the base plate, and a battery cavity is formed in the side wall of the ear rod shell, containing a button battery. A battery cover is located at the end of the battery cavity. A camera is located at the front end of the ear rod shell, and a magnetic charging connector is located at the rear end. This invention transmits real-time images of the ear canal to the electronic display screen through a camera integrated at the tip of the ear rod and a wireless signal transmitter. The experimenter can clearly observe the internal structure of the ear canal through the display screen, achieving precise positioning. The device has an animal category selection function and can generate virtual positioning auxiliary lines to help the experimenter quickly find the center point of the ear canal. Its wireless connection method is convenient to operate and can replace traditional ear rods in stereotactic brain positioning operations.

The application provides a high-precision DSM method for stereo image pair extraction of a no-control-point island reef, and first, a semi-global dense matching algorithm is used for semi-global dense matching to obtain a parallax map; second, a rational function model coordinate stereo positioning is performed to process longitude, latitude and height coordinates to obtain three-dimensional point clouds without deformation; finally, point cloud reconstruction DSM is realized to generate a DSM three-dimensional model. Experimental results show that the high-resolution satellite stereo image pair reconstruction DSM method is preferably applied to World-View3 satellite images and can generate a far-sea island reef DSM three-dimensional model.

This application discloses a stereoscopic positioning image positioning frame, including a CT positioning device and a fixation base. The CT positioning device includes a top fixing frame made of high-strength plastic. CT imaging panels are fixed to the front, left, and right sides of the top fixing frame, each containing an N-shaped marker pattern that is visible under CT images. The fixation base includes a front irregular crossbeam, a rear crossbeam, a left longitudinal beam, and a right longitudinal beam. Each fixing rod has a mounting part at its top for fixing to the user's skull. The CT positioning device and the fixation base are connected by a detachable connection structure, and in the connected state, the outer surfaces of the left and right longitudinal beams of the fixation base are flush with the outer surfaces of the left and right imaging panels of the CT positioning device. This stereoscopic positioning image positioning frame, equipped with marking patterns, facilitates subsequent automatic image positioning calibration and enhances user comfort and overall user experience.
