Handheld thermal infrared imager and method for same to carry out quick locking and ranging on small target

Abstract

The invention relates to a handheld thermal infrared imager. The handheld thermal infrared image comprises infrared imaging sensors, a visible light camera, a laser range finder, a Bluetooth module, a magnetic compass module, an MEMS micro gyroscope, a GPS module, a wireless transmission module, a Linux system embedded signal control panel and an LED display screen. Data of the multiple sensors can be integrated, resources can be reasonably allocated, complex algorithms can be achieved, the performance of handheld equipment can be improved, and the systematization of single machines can be improved. The invention further discloses a Linux-system-based algorithm for the handheld thermal infrared to carry out quick locking and ranging on a small target. According the principle of the MEMS micro gyroscope and the image processing algorithm, the target can be quickly and accurately locked and traced through digital images of infrared light and visible light, and the quick locking and ranging functions are effectively achieved through the laser range finder. The handheld thermal infrared can eliminate video jitters in real time, improve the video quality, lock the target quickly, recognize and detect the target distance automatically and improve the functionality of the handheld equipment.

Description

technical field [0001] The invention belongs to the technical field of infrared thermal imaging, and in particular relates to a hand-held infrared thermal imager based on a Linux system and a method for fast locking and ranging of small targets. Background technique [0002] With the rapid development of electronic technology and embedded technology, the performance of various mobile terminal hardware platforms has been rapidly improved, and the development of technology has also put forward new requirements for handheld portable thermal imaging cameras. Handheld thermal imaging cameras are moving towards Stand-alone systematization, miniaturization, and multi-function development. It is required to integrate CCD camera, laser ranging, Bluetooth, GPS, magnetic compass, wireless communication and other peripherals on the basis of infrared imaging. [0003] At present, each single sensor is widely used, and it is necessary to coordinate and manage multiple peripherals and mul...

Problems solved by technology

However, its small target is difficult to aim, and often deviates from the center of the laser optical axis due to jitter, and it is difficult to receive diffuse reflection signals

On the one hand, it makes it difficult to measure the target and greatly reduces the usability of the handheld device. At the same time, it also causes the laser range finder to always be in the process of charging and discharging, resulting in increased power consumption.
