Embodiment Construction
[0041] In order to enable those skilled in the art to better understand the solution of the present application, the present application will be further described in detail below in conjunction with the drawings and specific implementation methods. Apparently, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.
[0042] In the following description, a lot of specific details are set forth in order to fully understand the present invention, but the present invention can also be implemented in other ways different from those described here, and those skilled in the art can do it without departing from the meaning of the present invention. By analogy, the present invention is therefore not limited to the specific...

The present application discloses a method for moving a cursor, which is applied to FPGA, including obtaining the moving information of the cursor and the current coordinates of the cursor, the moving information including moving instructions and moving distance; determining the target coordinates of the cursor according to the current coordinates and moving information; determining the target The row distance and column distance between the coordinates and the center point of the display array where the cursor is located; move the cursor according to the relationship between the row distance and the column distance and zero respectively. The cursor in this application supports arbitrary customization; on the basis of not increasing the cost and power consumption, the moving speed of the cursor can be increased by 80%, which meets the real-time requirements of the cursor movement, and the movement efficiency is high. When the cursor fills the entire screen When the cursor is complex, it can move quickly, without the problem of stuttering, and improve the user experience. In addition, the present application also provides a device, equipment and an infrared thermal imaging system having the above-mentioned advantages.
Description
technical field [0001] The present application relates to the technical field of infrared thermal imaging, in particular to a method, device, equipment and infrared thermal imaging system for moving a cursor. Background technique [0002] Infrared thermal imaging uses photoelectric technology to detect infrared specific band signals of thermal radiation of objects, and converts the signals into images and graphics that can be distinguished by human vision. It is widely used in military, medical, industrial and many other fields. [0003] The cursor is an indispensable function in the infrared thermal imaging display system, and the moving speed of the cursor directly affects the efficiency of target tracking and infrared thermal imaging sight calibration. At present, the movement of the cursor is completed through software programs, and the movement speed of the cursor is slow. Moreover, when the cursor moves continuously or when the cursor is a complex cursor that fills the...
