Method and system for interactive editing of image control points

Abstract

The invention relates to a method and a system for interactive editing of image control points. The method comprises the following main steps of: detecting the system; loading data; displaying and refreshing data; detecting an input state; converting and transferring an instruction; modifying data; and the like. The involved hardware devices mainly comprise a computer and a universal force feedback handle; a software processing module is arranged in the computer; and thus, the method can be realized. The method and the system have the beneficial effects that the image control points can be browsed and edited and the data can be viewed simultaneously, continuous switching between an editing state and a view state can be realized, the universal force feedback handle is used for operation to guarantee low cost, meanwhile, images to be processed and reference data can be zoomed by moving the universal force feedback handle during editing of the image control points, an instruction emitted by application software can also be received as a response per se, and the probability of human error during editing is reduced.

Description

technical field [0001] The invention relates to image control in the technical field of photogrammetry and remote sensing, in particular to a method and system for interactive editing of image control points. Background technique [0002] In the field of photogrammetry and remote sensing, it is often necessary to use different shooting equipment or shoot from different angles for the same target. These images include the same physical target, and the target is the same point in the real coordinate system, but in each image The coordinate positions relative to the image pixels are different. These target points in different images are called control points or points of the same name. [0003] In the prior art, although automatic algorithms can be used to search and match image control points or stereo image pairs with the same name, their reliability is limited, and manual inspection and editing are still irreplaceable and important links in actual production.

Problems solved by technology

However, the mouse, keyboard, and dedicated electronic handwheel and pedal devices are only input devices, and cannot respond to commands issued by application software.

And most of the software for remote sensing data processing directly use the general-purpose mouse and keyboard as the input device, and the data processing itself needs to switch continuously between the editing and viewing states. View reference data while processing imagery

Therefore, the controllability of the mouse is poor, and the work efficiency is low; while the special handwheel and pedal are expensive and take up a lot of space. There is no standard product on the market, and the versatility is not strong.
