Image-based lead live-line distance verification method and terminal

The invention discloses an image-based lead live-line distance verification method and a terminal, and the method comprises the steps: obtaining a to-be-tested image of a to-be-tested lead, and constructing verification windows of different visual angles in the to-be-tested image according to the safety spacing information; if other wires exist in the first view angle verification window, a first target line segment which does not pass the verification is obtained, then the first target line segment is verified through a second view angle verification window, and whether the distance between the first target line segment and other wires is too small or not under the second view angle is judged. And when the first visual angle verification window and the second visual angle verification window do not pass the verification, calculating the distance between the first target line segment and other wires based on the to-be-tested image, thereby verifying whether the to-be-tested wire is qualified or not according
