Image control point interactive editing system

Abstract

The invention provides an image control point interactive editing system. The image control point interactive editing system is characterized by comprising a central processing unit, a data processing unit, an information command unit, a graphical interface unit and a handle, wherein the central processing unit is used for coordinating data transmission and function scheduling among all the units; the data processing unit is used for managing image data and control point data, and performing operation; the information command unit is used for getting a hardware state parameter and converting the hardware state parameter to a user command; the graphical interface unit is used for checking the image data and the control point data and monitoring the operation response of a user; and the handle comprises a left rocker, a right rocker, multiple function buttons and a force feedback responsor. The image control point interactive editing system disclosed by the invention can simultaneously move and zoom the image data and reference data, which need to be processed, during editing of a control point of an image, and further perform continuous switching between an editing state and a checking state. In addition, the opportunity of causing human error during editing can be reduced and the low-cost implementation can be realized.

Description

technical field [0001] The invention relates to an image control point interactive editing system, in particular to a system for browsing and editing image control points in fields such as photogrammetry and remote sensing. Background technique [0002] At present, in the field of photogrammetry and remote sensing at home and abroad, control point matching is the necessary data for geometric correction of remote sensing images. Although it is possible to search and match image control points or stereo image pairs with the same name through automatic algorithms to a certain extent, manual inspection and editing are still an irreplaceable important link in actual production, and traditional computer peripherals are usually used in this link For example, the computer's standard mouse or special electronic handwheel and pedal are used as operating equipment, and these external equipment are used to move and zoom the image pair respectively. [0003] The cycle of obtaining image...

AI Technical Summary

Problems solved by technology

[0003] The cycle of obtaining image control points in the traditional way is long, and a large amount of work is manually selected. The accuracy of the control points is affected by the operator's proficiency, technical level, and own conditions, and due to the inconvenient equipment, resulting in work Large volume and low degree of automation, poor reuse performance of control point data

When using the mouse as the operating device, the handling is poor and the work efficiency is low

In the case of using special handwheels and pedals, the cost is high and the space occupied is large, and because there is no standard product on the market at present, the versatility is not strong
