摘要： A method of recognizing a stop line in an autonomous vehicle is disclosed. The method includes detecting valid stop line data in a current frame of an input image, when the valid stop line data is detected in the current frame, calculating a stop line area in the current frame using a tracking algorithm and tracking the stop line in a next frame, and when the valid stop line data is not detected, inputting the current frame to a trained neural network model and performing a redetection of the stop line data.

摘要： A nerve cover for covering a nerve within a living body tissue to protect the nerve includes a base of a flat plate shape, and a pair of covers protruding upward the base to form a hole for receiving a nerve, with one end attached to the base and the other end spaced apart from the one end, wherein when the base is bent in an arch shape when viewed from a side, a spacing between the pair of covers is expanded. In addition, an apparatus for insertion of an electrode structure includes a nerve cover fixing part which fixes the nerve cover with the base being bent, and an electrode structure fixing part in which the electrode structure is mounted, and which linearly moves the mounted electrode structure in an insertion direction to insert the electrode structure into the nerve surrounded by the nerve cover.
