Problems solved by technology
The traditional airborne aerial remote sensing method to solve the outer orientation elements is generally to use a certain number of ground control points and use the method of spatial triangulation encryption to obtain the outer orientation elements. Due to the need for ground control points, the workload in the field is very large, the cost is high, and the data Post-processing time is also very long

A real time sampling device and method of machine carried multi-angle multi-source data, which contains at least two matrix camera and two image sampling card in a computer connected with cameras, each sampling card connected with a group of hard disk array, a pose device POS system connected with main control computer. Said method containing the camera working in external activating mode, POS system worked synchronous with camera and sampling image and POS event data transmitted to cache of sampling card and integrated and divided by driving engine, then transmitted to display memory by PCI bus and hard array by Ultra160 interface of board carried SCSI controller for real time display and storage, sampling engine communicated with pose measuring POS system, the POS event data transmitted to memory of computer, sampling engine controlling the corresponding with relative image data.
Description
Technical field: [0001] The invention relates to a high-resolution airborne multi-angle image collection, in particular to a collection device and method for real-time fusion of image data and attitude measurement POS (geographical coordinate parameter) data. Background technique [0002] Remote sensing earth observation technology is mainly a macroscopic observation technology for understanding nature by obtaining spectral characteristic information of natural targets on the earth's surface, that is, processing and processing these information. Specifically, there are mainly the following stages: [0003] (1) Single sensor stage where spectral information is mainly obtained [0004] This stage is mainly qualitative, that is, the main goal is to obtain ground images. However, the accuracy of the parameters of the attitude measurement device used for positioning is very low, that is, the accuracy of positioning the acquired images is very poor. [0005] (2) The stage of sin...
