Economical airborne oblique digital aerial photography system

Abstract

The invention discloses an economical airborne oblique digital aerial photography system, which is composed of eight parts including front, back, left and right oblique photographing units, one vertical photographing unit, a connection base plate, a micro GPS (Global Position System) navigator and a system controller. Each photographing unit is composed of a CCD (Charge Coupled Device) working camera, a camera fixing piece, a camera rotating base and a camera protection cover, the four oblique photographing units can rotate at multiple angles around the plane of the connection base plate, and the vertical photographing unit is vertically fixed on the plane of the connection base plate; and a camera control line and a power line are connected with the system controller through a distributing box, and a data output port of the GPS navigator is connected with the system controller. Except for the controller, the parts of the system are fixed on the connection base plate, and the system realizes isochronous or equidistant photographing and synchronous acquisition of GPS navigation data through the system controller. The economical airborne oblique digital aerial photography system overcomes the defects that the conventional aerial photography is lack of image facade information, the existing oblique aerial photography system is expensive, and the like, and can effectively meet the requirements on rapid acquisition and application of urban geographic information.

Description

technical field [0001] The invention relates to an economical airborne tilting digital aerial photography system, which belongs to the comprehensive cross-technical field of mechatronics, automatic control and digital photogrammetry technology, and is mainly used in geographic information such as aerial surveying and mapping, homeland security, real estate management, digital cities, etc. Related industries and fields can effectively meet the requirements of rapid acquisition and application of urban geographic information. Background technique [0002] Airborne oblique photography is a high-tech aerial photography technology developed in the field of international surveying and mapping in recent years. It collects space images of different sides of ground objects by carrying multiple sensors with different camera angles on the same flight platform. Airborne oblique photography subverts the vertical photography mode of traditional aerial photography. The multi-angle oblique ...

Problems solved by technology

[0003] Purpose of the present invention: to provide a low-altitude remote sensing-oriented low-altitude airborne tilting digital aerial photography system that supports a variety of photographic angles by using ordinary commercial CCD digital cameras with medium and long focal lengths as the working camera. The oblique photography system is expensive, high in operating costs, single in oblique photography angle, and has high requirements for the flying platform. It can obtain high-definition oblique image data from different angles in real time and flexibly, and is suitable for users to browse from multiple angles and measure simple geographic information. Different levels of image requirements such as precise mapping can effectively meet the application purposes of geographic information related industries such as aerial mapping, homeland security, real estate management, and digital cities
