A man-machine interaction method of infrared thermal imager based on FPGA

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...
