Example Embodiment

[0026] Example 1

[0027] The specific steps of an FPGA-based human-computer interaction method for infrared thermal imaging cameras are:

[0028] The first step is to build a human-computer interaction system

[0029] The human-computer interaction system includes: a key control module, a font generation module, and a coe file generation module.

[0030] The function of the button control module is to control the movement of the highlighted button on the interface through the external button to realize human-computer interaction.

[0031] The function of the font generation module is to generate the text font required by the highlight button on the interface, and generate a .txt file.

[0032] The function of the coe file generation module is: use matlab to generate a .coe file for each line of text.

[0033] Step 2: The button control module controls the movement of the interface buttons on the display interface

[0034] The button control module has seven button functions. The button fu...

Abstract

The invention discloses a man-machine interaction method of an infrared thermal imager based on FPGA, which includes: adopting pixels with low gray value to construct graphics, storing in ROM of FPGA,controlling to read according to time sequence signal, replacing a part of pixel values of the collected image, forming gray value difference with peripheral high gray value images, and completing the manufacture of graphics interface. The complex text interface font generation is very succinctly completed, and the complex text interface font is solidified in the ROM, after the product is poweredon, the product is output with the image data stream, and the difference gray scale display of the image and the interface is used to realize the interactive interface display, so that the human eyecan read the text information intuitively, and the command menu of the thermal imager is opened, closed, switched and confirmed through seven keys.

Description

technical field [0001] The invention relates to a human-computer interaction method for an infrared thermal imager, in particular to an FPGA-based human-computer interaction method for an infrared thermal imager. Background technique [0002] Infrared cooling thermal imaging camera, hereinafter referred to as thermal imaging camera, because the detector works stably in a low temperature environment, it is necessary to send some control commands such as calibration to the thermal imaging camera before normal operation. In addition, according to different use environments and targets, the gain parameters, brightness, internal and external synchronization, focal length and many application functions of the thermal imager need to be manually changed in real time. Therefore, UI, User Interface, is an essential part of the thermal imager system. [0003] At present, there are two mainstream methods to realize UI design: one is to realize interface communication through the periph...
