Title:
BASE STATION, PHOTO-CONTROL-POINT POSITIONING METHOD, ELECTRONIC DEVICE AND COMPUTER READABLE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2021/007855
Kind Code:
A1
Abstract:
Disclosed are a base station, a photo-control-point positioning method, an electronic device and a computer readable medium. The base station comprises a support member (110) and a target (120); a first antenna and a GNSS receiver (111) are installed at the top of the support member (110), and the first antenna is connected to the GNSS receiver (111); the target (120) is fixedly connected to one side of the bottom of the support member (110), a second antenna is installed in the center of the target (120), the second antenna is connected to a GNSS chip (121), and the center of the target serves as a photo-control point during aerial surveying; and the GNSS receiver (111) and the GNSS chip (121) are respectively in communication connection with a processor, and the processor is used for determining a baseline vector coordinate difference between the first antenna and the photo-control point on the basis of satellite data acquired by the GNSS receiver (111) and the GNSS chip (121), and for determining coordinates of the photo-control point on the basis of the coordinates of the first antenna and the baseline vector coordinate difference. The base station has a function of positioning a photo-control-point, such that the efficiency of positioning a photo-control-point is improved.
