Abstract

The invention discloses a fisheye lens-based radio wave positioning system, positioning and charging method. The spatial positioning module includes a fisheye lens, an antenna end face, a receiving antenna, and a receiver; the fisheye lens is provided with a convex lens group and a concave lens group, and the convex lens group and the concave lens group are arranged in sequence; the antenna end face is arranged at the focal plane of the fisheye lens; the receiving antenna is arranged on the top of the antenna end face, the number of receiving antennas is at least one, and the receiving antennas form an antenna array; the number of receiver channels corresponds to the receiving antenna, The receiver is connected to the receiving antenna, and the receiver is connected to the signal control module; the signal control module and the space positioning module establish a connection relationship through the receiver. The invention can locate multiple users by using the receiving antenna through the fisheye lens, saving space occupancy rate. The invention can also be applied to the charging of radio waves to realize mobile charging of medium-power and low-power devices, and realize directional transmission of energy , thereby improving energy utilization.

Description

technical field [0001] The invention relates to the technical field of radio wave applications, in particular to a fisheye lens-based radio wave positioning system, charging and positioning methods. Background technique [0002] Fisheye lens is an extreme wide-angle lens, also known as panoramic lens, its visual effect is similar to that of fish observing things on the water surface. In engineering, lenses with a viewing angle exceeding 140 degrees are collectively referred to as fisheye lenses. In practice, there are also lenses with viewing angles exceeding or even reaching 270 degrees. One of the characteristics of fisheye lens imaging is that it can correctly describe the image point of the target point in the three-dimensional space on the imaging plane, and can accurately establish the corresponding relationship. Any point in space can be mapped to the focal plane through the fisheye lens. corresponding imaging point. The traditional fisheye lens is usually used in t...
