Embodiment Construction

[0060] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0061] figure 1 The flow chart of the multi-target automatic temperature measurement method provided by an embodiment of the present invention is shown, and the method includes the following steps:

[0062] Step S101 , adopting a multi-target automatic distinction method to obtain heat source information within the layout.

[0063] In this step, the multi-target automatic discrimination method is mainly used to improve the heat source detection ability, accurately distinguish the position of the heat source in the layout, and effectively prevent the occurrence of secondary fires caused by unknown fire sources. Obtain the heat source information in the layout. The layout refers to the range that needs to be detected, such as a room or a f...

Abstract

The invention relates to the field of temperature detection, and provides a multi-target automatic discrimination temperature measurement method, which includes: a multi-target automatic discrimination method and a temperature measurement model, and the invention also provides a corresponding system. Not only can it automatically distinguish multiple targets, it can also use the temperature measurement model to compensate the temperature of the heat source, and measure and calculate the real temperature of the object more preparedly. The multi-target automatic discrimination method can effectively prevent the omission of heat sources in the detection environment, greatly reducing the occurrence of secondary fires caused by unknown fire sources; the temperature measurement model overcomes the influence of a series of factors, and more accurately measures the temperature of object heat sources, greatly Improved temperature measurement accuracy.

Description

technical field [0001] The invention relates to the field of temperature detection, in particular to a method and system for multi-target automatic discrimination temperature measurement. Background technique [0002] Common general infrared thermal imager front-end test temperature measurement principle: at the same temperature, the radiated power of the same wavelength of the actual object is always less than the law of black body radiation. The thermal radiation of actual objects is in the infrared wavelength range, which can be approximated as gray body radiation. The naked data value of each point in the thermal image has a corresponding relationship with the infrared radiation value on the surface of the object, but the temperature calculated directly from the naked data value is not the real surface temperature of the object. According to Planck’s radiation law, it can be simulated The fitting curve method converts this to the real object temperature. [0003] Fitti...
