Novel single-lens stereo mapping device and mapping method

Abstract

The invention relates to a novel single-lens stereo mapping device and a mapping method. The novel single-lens stereo mapping device comprises a rotatable plane mirror and an imaging detector, whereinan optical lens is arranged between the plane mirror and the imaging detector; and two star sensors are arranged on the plane mirror and a camera lens barrel separately. The mapping method comprisesthe steps of at the initial measurement moment, adjusting a camera at forward-looking theta1, imaging an area A and keeping flying at the angle, thereby completing mapping of an area AB at an angle oftheta1; and at the middle measurement moment, rotating the plane mirror, adjusting the camera at forward-looking theta2, imaging the area A again, keeping imaging on B at the angle and ending measurement, thereby obtaining images of two angles of the area AB for post processing. The novel single-lens stereo mapping device and the mapping method have the characteristics that flexible mapping at high positioning accuracy and a variable base-height ratio can be achieved by using a lightweight single-lens mapping camera, and the novel single-lens stereo mapping device and the mapping method are especially applicable to light-small stereo mapping satellites with high positioning accuracy.

Description

technical field [0001] The invention belongs to the technical field of aerospace surveying and mapping, and relates to a variable base height ratio stereoscopic surveying and mapping technology applicable to earth observation, in particular to a novel single-lens stereoscopic surveying and mapping device and a surveying and mapping method. Background technique [0002] The main function of the surveying and mapping camera is to take stereoscopic photography of the ground surface, obtain multi-dimensional image data of ground objects, use surveying and mapping processing technology to process the image data, accurately measure information such as terrain, landform, and ground object shape, size, and spatial position, and generate support Various supporting products for battlefield operations and economic construction. [0003] With the rapid development of aerospace remote sensor technology, the requirements for light weight and flexibility of surveying and mapping cameras co...

Problems solved by technology

[0007] However, the surveying and mapping method of changing the surveying and mapping angle by the whole star swing requires the satellite to change its attitude frequently to complete the scanning of the ground at different angles

Therefore, the use of the whole star swing method seriously consumes satellite fuel and greatly shortens the satellite's on-orbit life.
