Title:
METHOD AND APPARATUS FOR LINE-OF-SIGHT MEASUREMENT AND POSITIONING, AND COMPUTER DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/208398
Kind Code:
A1
Abstract:
A method for line-of-sight measurement and positioning, comprising: obtaining a target test point located in an overlapping imaging area of dual cameras; performing dual-camera ranging on the target test point, and obtaining a first coordinate of the target test point in a camera coordinate system (S2); and obtaining a second coordinate of the current location in a geodetic coordinate system, and calculating latitude and longitude data of the target test point in the geodetic coordinate system. The characteristics of the overlapping imaging area of the dual cameras make up for the shortcomings of existing measurement methods.
