Embodiment Construction

[0016] figure 1 It is a system structure diagram of the panoramic digital imaging system of the present invention. The panoramic digital imaging system of the present invention is composed of a high-speed digital imaging system (1), an industrial control system (2), a braking system (3), a power supply device (4), data preprocessing software (5) and other optional equipment. The system is installed on the motion platform, and the high-speed digital imaging system (1) is driven by the braking system (3) to move back and forth at a constant speed on a circular line at a certain angle, and obtain multiple overlapping digital images in a short period of time. The supporting data preprocessing software (6) can perform relative orientation and seamless splicing of partial digital images in the same cycle, and generate panoramic images with a field of view of more than 180 degrees.

Abstract

The invention relates to the field of photogrammetry, remote sensing and spatial information acquisition, in particular to a panoramic digital imaging system based on a motion platform and swing type high-speed digital imaging technology. The system comprises a high-speed digital imaging system (1), an industrial control system (2), a brake system (3), a power supply device (4), data pretreatment software (5) and other optional equipment. The system can be assembled on any movement platform; the brake system (3) drives the high-speed digital imaging system (1) to do reciprocating constant swing on an arc trace to continuously expose in a short time so as to acquire a plurality of local digital images mutually overlapped. The data pretreatment software (5) carries out characteristic point extraction, relative orientation, free net adjustment calculation, imaging transformation, image distortion correction, image montage and the like. The system can generate panoramic digital images with view angle over 180 DEG and has an image acquisition rate of 1 Hz. The system provides a solution with high efficiency and low cost for panoramic image digital acquisition.

Description

technical field [0001] The invention relates to the fields of photogrammetry, remote sensing and spatial information acquisition, in particular to a panoramic digital imaging system and method based on swinging high-speed digital imaging technology. Background technique [0002] At present, most panoramic image systems on the market are based on multi-camera combination systems, that is, multiple cameras are integrated together, controlled by one or more industrial control computers, and exposed at the same time to obtain partial images in all directions at the same position. Panoramic images are then obtained by splicing. The position of each camera is relatively fixed, and there is a fixed geometric relationship between the cameras, but generally the overlap between the images is not large, and the system calibration work is very complicated. Problems such as synchronization will lead to higher system costs. [0003] A single-camera system is used to image the scene manu...
