Embodiment Construction

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0021] Such as figure 1 As shown, firstly, according to the distribution characteristics of the visual field in the static state of the human eye, the horizontal visual angle range φ that the human eye has when looking straight ahead is obtained.

[0022] Design a head-mounted device worn on the user's head, and use at least two head-mounted cameras to divide the work to obtain horizontal 360-degree panoramic images around the user, wherein the camera located ...

Abstract

The present invention discloses an eye visual characteristic-based panoramic view display method. According to the method, the horizontal viewing angle Phi of the eyes of a user when the user looks straightly ahead is obtained; cameras are adopted to obtain a horizontal 360-degree panoramic image around the user, the front-surface camera displays an image which is located in front of the user andis larger than Phi in a main field of view window, the rear camera displays images which are located at the left side, right side and rear side of the user and are larger than an angle of (90-Phi/2) degrees at a left auxiliary field of view window and a right auxiliary field of view window respectively in a compressed manner; the three images are spliced and combined, the movement of the eyes is tracked at the same time, and images at the focusing position of the eyes and in a width area which extends towards two sides for a limited distance can be displayed normally and are not deformed. Withthe method adopted, a soldier can be assisted to know the situation of 360-degree peripheries around the side and rear of the soldier without turning his or her head in a combat, and therefore, combat capability can be effectively improved. The method of the invention has a bright application prospect in the military and civilian recreation field.

Description

technical field [0001] The invention belongs to the application field of optoelectronic technology, and in particular relates to a method for presenting a panoramic view based on the visual characteristics of human eyes. Background technique [0002] At present, some developed countries in the world are intensively formulating and organizing the implementation of individual combat system development plans. Individual combat weapon system platforms adapted to their respective national conditions have sprung up, especially the head-mounted system has become the external brain of soldiers. Soldiers will realize intelligent informatization on the battlefield. The smart glasses they wear can transmit map information, send images to their companions, and help soldiers warn each other of potential threats, such as traps and ambushes. In combat and training, observation capability is very important for combat. The visual power of the human eye refers to the degree of the viewing an...
