Abstract: Provided by the present invention are a method and system for automatically optimizing 3D stereoscopic perception, and a medium. The method comprises the following steps that are executed successively: step 1: given current left and right images, calculating a stereo disparity to generate a disparity map; step 2: calculating a depth value corresponding to each individual pixel by using the calculated disparity; step 3: calculating a depth distance of a target to be observed; step 4: acquiring corresponding left and right image displacement values by using the depth distance calculated in step 3; and step 5: applying the acquired image displacement values into a 3D display. The beneficial effect of the present invention is that: the method for automatically optimizing 3D stereoscopic perception according to the present invention solves fatigue and dizziness that are easily generated during the use of a 3D endoscope.

Abstract: A capacitive voltage transformers for distribution of the power from 10 kv high potential line, includes a insulating column with a high potential terminal, a ground terminal and capacitors C1 and C2 in series connection. The column is filled with oilless dry filler. The capacitors C1 and C2 formed by a plurality of separated metallized film capacitors respectively in series or in parallel connection. At the tapping point between the capacitors there is a leading-out terminal of the secondary voltage which is connected to an induction transformer L in parallel. The transformer includes a frame with “C” shaped iron cores and windings wound around the cores. There is an over-voltage protector P connected in parallel between the tapping point and ground. A capacitive voltage divider is integrally combined with the transformer to provide a small volume, low cost device with a savings in materials.
