TLDR
In this article, a microscopic thermal imaging method is proposed to solve the problem that ideal micro-scanning position points with respective shortage of half pixel cannot be obtained due to influence of factors of environment, mechanical vibration, device processing precision and other factors.
Abstract: 
The invention discloses a microscopic thermal imaging method Firstly four low-resolution undersampling micro-scanning images of an object are acquired; then four standard 2x2 uniform micro-scanning undersampling images are acquired according to the four low-resolution undersampling micro-scanning images; and finally a high-resolution oversampling thermal image is acquired by cross merging of the four standard 2x2 uniform micro-scanning undersampling images The microscopic thermal imaging method aims at a problem that ideal micro-scanning position points with respective shortage of half pixel cannot be obtained due to influence of factors of environment, mechanical vibration, device processing precision and other factors, and the high-resolution oversampling image is obtained by utilizing the low-resolution undersampling micro-scanning images through practical acquisition so that the ideal micro-scanning position points can be obtained The microscopic thermal imaging method can be completed only by algebraic operation so that the microscopic thermal imaging method is simple, rapid and stable, imaging quality is enhanced and application and popularization of the optical micro-scanning microscopic thermal imaging technology in all fields can be facilitated
