Embodiment 1

[0039] see figure 1 - Figure 4 , a map fusion intelligent target detection method; the detection method includes the following steps in sequence:

[0040] Step 1: Perform infrared image target recognition on the target to be recognized to obtain the first recognition result, if the first recognition result can reach the expected recognition rate, then end the operation, if the first recognition result cannot reach the expected recognition rate, then enter the second step ; The infrared image target recognition of the target to be recognized to obtain the first recognition result means: first obtain the first infrared image through the infrared light radiated by the target to be recognized, and then extract the first region of interest on the first infrared image , and then use the shape and grayscale to identify the first ROI to obtain the first identification result;

[0041] The second step: performing infrared spectrum correlation target recognition on the target to be r...

Embodiment 2

[0043] Basic content is the same as embodiment 1, the difference is:

[0044]The locking the ROI of A to the center of the field of view refers to: using the target tracking and motion control technology to lock the ROI of A to the center of the field of view. The use of target tracking and motion control technology refers to: controlling and adjusting the angle of the scanning mirror.

Embodiment 3

[0046] Basic content is the same as embodiment 1, the difference is:

[0047] The extraction of spectral features from infrared spectral information refers to: extracting peaks and valleys from infrared spectral information through spectral data processing to obtain spectral features. The identifying the spectral features to obtain the second identification result refers to: comparing the acquired spectral features with the spectral features in the spectral fingerprint library one by one to obtain the second identification result.

Abstract

The invention relates to a spectrum fusion intelligent target detection method which comprises a first step and a second step which are sequentially carried out. The first step is to carry out infrared image target recognition on a target to be recognized so as to obtain a first recognition result, if the first recognition result can reach an expected recognition rate, the operation is finished, if the first recognition result cannot reach the expected recognition rate, entering the second step; the second step is that the target to be recognized is recognized by the infrared spectrum associated target to obtain a second recognition result, the second recognition result is taken as a final recognition result, and the operation is finished at the same time. The spectrum fusion intelligent target detection method and light path switching device thereof not only has the recognition result and the recognition cost, but also has high cost performance and simple operation.

Description

technical field [0001] The invention relates to an image recognition design, in particular to an image spectrum fusion intelligent target detection method and an optical path switching device thereof, which are specifically suitable for combining recognition results and recognition costs and improving cost performance. Background technique [0002] At present, as long as its own temperature is higher than absolute zero, the object can produce infrared radiation and radiate infrared light. At the same time, the infrared spectrum can be obtained according to the infrared light radiated by the object, and the infrared spectrum is unique. In the prior art, this unique feature is often used to recognize objects, and a variety of recognition methods have been developed. However, in practical applications, due to different requirements, such as different requirements for recognition rates, if all of them use infrared spectroscopy to carry out Recognition not only increases the cos...
