Abstract

An embodiment of the invention discloses a calibration method and a calibration device on the basis of POS (position and orientation system) equipment and digital aerial survey cameras, and relates tomeasurement and remote sensing technologies. The calibration method on the basis of the POS equipment and the digital aerial survey cameras includes converting attitude information recorded by the POS equipment to obtain image direct geographic positioning exterior orientation element initial values, acquiring exterior orientation elements by the aid of single-chip resection processes and solvingthe exterior orientation elements; checking obtained multi-sensor data by the aid of position and attitude parameters on the basis of the POS equipment and auxiliary aerial triangulation exterior orientation element interaction verification processes on the basis of GPS (global positioning system) equipment; carrying out absolute orientation by the aid of the image direct geographic positioning exterior orientation element initial values and control points directly, uniformly acquiring field checking points of calibration fields and carrying out calibration. The exterior orientation elementsare used as true values. The calibration method and the calibration device have the advantages that system integration errors can be effectively calibrated by the aid of the calibration method and calibration device; the calibration method and the calibration device are applicable to calibrating the exterior orientation elements.

Description

[0001] This application is a divisional application of an application with an application date of July 21, 2016, an application number of 201610579121.5, and an invention titled "A verification method and device based on POS equipment and a digital aerial survey camera". technical field [0002] The invention relates to measurement and remote sensing technology, in particular to a verification method and device based on POS equipment and a digital aerial survey camera. Background technique [0003] Inertial Measurement Unit (IMU, Inertial Measurement Uint) / DGPS, Differential Global Positioning System (DGPS, Differential Global Positioning System) assisted aerial photogrammetry technology is an emerging technology in the world. various fields of remote sensing. The IMU / DGPS system has become the necessary equipment for digital aerial cameras and airborne laser scanning systems. At present, through the installation of positioning and orientation system (POS, Position and Orie...
