Projected image geometric distortion automatic correction system and correction method thereof

Abstract

The invention relates to a projected image geometric distortion automatic correction system and a correction method thereof. The hardware part of the system comprises an offer measurement and control computer, a projector, an angle detection system, an image fusion computer and an imaging computer; the software part is geometric distortion automatic correction software; the software comprises a digital camera image acquisition and processing unit, a cloud platform control unit, a projector setting module and a projector correction processing unit; through cooperative work of the geometric distortion automatic correction software and hardware, the projected image geometric distortion automatic correction can be realized, and the technical difficulties of poor overall picture effect after the manual image correction and long adjustment time are solved.

Description

Projection Image Geometric Distortion Automatic Correction System and Correction Method technical field The invention belongs to the field of projection image processing, in particular to a projection image geometric distortion automatic correction system and its correction method. Background technique Multi-channel large field of view projection display system has been widely used in virtual battlefield environment simulation, military training simulation, digital city planning, 3D geographic information system, etc. due to its large field of view and high-presence visual effects. In recent years, multi-channel large-field-of-view projection display systems have begun to develop in the fields of exhibition display, dispatch control, security monitoring, command control, industrial control, education and training, conference centers, and battlefield command. The multi-channel large field of view projection display system is supported by multi-channel visual synchronizati...
