摘要： The present disclosure discloses a method and a device for converting two-dimensional (2D) images into three-dimensional (3D) images and a 3D imaging system, wherein the method comprises the following steps: acquiring 2D image to be processed; performing perspective transformation on the 2D image to obtain a left-eye image and a right-eye image respectively; adjusting a distance between the left-eye image and the right-eye image according to the result of perspective transformation; and synthesizing the left-eye image and the right-eye image after the distance adjustment. In embodiments of the present disclosure, binocular parallax images are created by performing perspective transformation on the 2D image to be processed; the distance between the left-eye image and the right-eye image after perspective transformation is adjusted to form binocular parallax and create a convergence angle, so that the images observed by naked eyes are located at different depths, thus different stereoscopic effects may be seen. The image transformation is performed on the 2D image without involving the resolution and definition of the image, so that the image quality of the 3D imaged image is the same as that of the original 2D image and the 3D imaging effect is not affected.

摘要： Disclosed are an image processing method and device, and a three-dimensional imaging system. The method comprises the following steps of: acquiring a two-dimensional image to be processed; aligning the two-dimensional image to be processed to a grid template; performing mapping processing on the two-dimensional image to be processed by using a grid mapping table to acquire a first image, wherein the grid mapping table is used for representing the mapping relationship of grid images; mirroring the first image to acquire a second image; and synthesizing the first image and the second image to acquire the superimposed image of the first image and the second image. According to the method, the grid template and the grid mapping table are used for performing mapping processing on the two-dimensional image to be processed so as to simulate a left-eye image and a right-eye image acquired by human eyes; and a same two-dimensional image to be processed need to be mapped only once to acquire the left-eye image and the right-eye image, the steps of image processing being reduced, thus the time of image processing being shortened, and providing favorable conditions for the follow-up real-time conversion of the superimposed two-dimensional image into a three-dimensional image.

摘要： A ureteral catheter structure, comprising a catheter body (1). The catheter body (1) comprises a stepped braided tube (2), a bending tube (3), and a plastic catheter tip (14) which are spliced with each other. A first stainless steel outer tube (4) supports and connects the stepped braided tube (2) and the bending tube (3) at a splice therebetween, and a first PET heat-shrinkable film (5) is coated on the first stainless steel outer tube (4). A second stainless steel outer tube (6) supports and connects the bending tube (3) and the plastic catheter tip (14) at a position therebetween, and a second PET heat-shrinkable film (7) is coated on the second stainless steel outer tube (6). A traction wire (8) is provided within the catheter body (1), an end of the traction wire (8) being fixed on the bending tube (3), while the other end passing through the stepped braided tube (2). A heat-shrinkable sleeve (9) is provided outside the bending tube (3). An end of the ureteral catheter may be independently bent in multiple sections, thereby achieving a good detection effect, and solving the technical problem of instability when an end of the ureteral catheter is deflected.

摘要： An endoscope camera system and an image signal transmission method thereof are aimed at resolving a problem that an existing endoscope camera system cannot ensure a normal image output. The system may include a camera module, an image processing module, a front panel function switching module, a front panel control module, and a plurality of signal forwarding modules; when image signal transmission between an external monitor and the image processing module is abnormal, a signal forwarding module m is configured as a signal forwarding station that is used for bridging the image signal transmission between the image processing module and the external monitor. After receiving an image signal, the signal forwarding module m reprocesses the image signal and continues to send the image signal to the external monitor, thereby effectively avoiding signal attenuation and signal interference during the image signal transmission, and achieving an effect of ensuring a normal image output.
