Walking-assisting spectacles applicable to patient with tubular visual field and walking assisting method

The invention provides a pair of walking-assisting spectacles applicable to a patient with a tubular visual field, belonging to the technical field of biomedical engineering. The walking-assisting spectacles comprise a micro camera, an orientation-indicating-lamp early-warning mechanism and a microprocessor, which are all arranged on the spectacles, wherein the micro camera is connected with the microprocessor and outputs a picture signal; the microprocessor is connected with the orientation-indicating-lamp early-warning mechanism and outputs a light early-warning signal; the orientation-indicating-lamp early-warning mechanism is provided with a plurality of orientation indicating lamps; and the orientation indicating lamps are arranged at the periphery of lenses of the spectacles and carry out directional projection to the center of a tubular visual field. The walking-assisting spectacles provided by the invention can effectively detect suspectable obstacles in deficient visual fields and determine whether t
