Technical Field

The invention relates to the technical field of photographic mechanisms, in particular to a rotary single-lens oblique photographic mechanism for an aircraft.

Background

An aircraft refers to an aircraft capable of controlled flight in the atmosphere. Any aircraft must generate lift greater than its own weight in order to be able to ascend into the air. Aircraft can be divided into two main categories according to the principle of generating lift: lighter-than-air aircraft and heavier-than-air aircraft. The former is lifted off by air static buoyancy; the latter is lifted off against its own weight by aerodynamic force. Aircraft is a large category of aircraft, and refers to any machine that achieves aerodynamic lift-off flight through the relative movement of the fuselage and air (not the reaction of the air against the ground). Including balloons, airships, airplanes, gliders, gyroplanes, helicopters, ornithopters, tiltrotors, etc.

The oblique photography automatic modeling technology is a high and new technology which is rapidly developed in the field of international remote sensing and surveying and mapping in recent years. At present, a plurality of surveying and mapping units and related enterprises at home and abroad widely adopt the technology to produce three-dimensional model data, and gradually replace the traditional manual modeling, so that the technology becomes an important mode for producing a new three-dimensional model. The large-scene live-action three-dimensional model based on the oblique images can provide richer geographic information for users, is more friendly to user experience, and is widely popular at home and abroad. However, this technique is slow in development and difficult to popularize, and is mainly limited by an imaging device for acquiring an oblique image.
