The invention relates to a moveable non-inductive panoramic sensing method based on 3D laser. The method is characterized by, through a laser beam emitted by a laser in real time and a collision detection algorithm of a moving object, identifying the type of the moving object with size and contour features of the reflected laser beam region; and independently identifying the contour features of the moving object, which is a mobile person, thereby realizing precise spatial positioning of the mobile person in a 3D map scene, furthermore, realizing risk judgment of coming into or out of the region by mistakes and providing safety warning and reminding for substation supervisors and on-site operators. The method can realize remote centralized monitoring and management, thereby effectively reducing work burden of monitoring personnel, improving work efficiency, and greatly improving field operation control efficiency and on-site operation safety.
