Abstract

Embodiments of the invention disclose a verifying method and apparatus based on POS equipment and digital aerial survey camera, related to measurement and remote sensing technology and capable of effectively verifying system integration errors. The verifying method based on POS equipment and digital aerial survey camera comprises: using POS equipment to record attitude information, converting to obtain image direct geographical positioning exterior orientation element initial value, acquiring exterior orientation elements as true values by using a single-photograph resection method, and resolving exterior orientation elements; validating acquired multi-sensor data by using a cross-validation method of POS equipment-based positional attitude parameters and GPS equipment-supported aerotriangulation exterior orientation elements; using the image direct geographical positioning exterior orientation element initial value and directly using control point absolute orientation to evenly acquire and validate off-site surveillance check points for verification. The invention is applied to verification of exterior orientation elements.

Description

technical field [0001] 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 [0002] 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 Orientation System) equipment in the IMU / DGPS system, an integrated aerial remote sensing system can be formed, which can directly measure the attitude parameters of the IMU / DGPS system, and through joint processing of IMU and DGPS data , which can quickly obtain the high-prec...
