【摘要】：一切物體都可以產(chǎn)生紅外輻射，不同溫度的物體產(chǎn)生的輻射強(qiáng)度不一樣，紅外探測(cè)器可以探測(cè)出這種輻射的強(qiáng)弱從而生成紅外圖像。目標(biāo)的紅外圖像和可見(jiàn)光圖像不同，它不是人眼所能看到的外形輪廓圖像，而是直觀呈現(xiàn)目標(biāo)表面溫度的分布情況，紅外熱成像就是將人眼不能直接看到的目標(biāo)表面溫度分布變成人眼可以看到的代表目標(biāo)表面溫度分布的熱圖像。 本項(xiàng)目在紅外成像技術(shù)成熟的前提下，以氧化釩為紅外探測(cè)材料，相應(yīng)的驅(qū)動(dòng)電路及模數(shù)轉(zhuǎn)換電路、USB模塊、OMAP3530嵌入式系統(tǒng)為硬件平臺(tái)，在Linux環(huán)境下，采用交叉編譯的方法，以QT為工具開(kāi)發(fā)了一套功能完善的軟件系統(tǒng)，包括紅外圖像實(shí)時(shí)顯示、錄像、截圖等。本軟件是在PC機(jī)上Linux系統(tǒng)中搭建ARM交叉編譯環(huán)境生成可執(zhí)行代碼，然后在OMAP3530嵌入式系統(tǒng)中運(yùn)行。 本項(xiàng)目以USB數(shù)據(jù)線為傳輸方式，將前端紅外探測(cè)器探測(cè)到的目標(biāo)溫度信息傳輸?shù)角度胧较到y(tǒng)以視頻的形式顯示出來(lái)。當(dāng)探測(cè)目標(biāo)與其背景溫度相差不大時(shí)，對(duì)比度會(huì)很低，加上環(huán)境以及電路的噪聲，得到的原始數(shù)據(jù)會(huì)不利于觀察，為了改善這種缺陷，軟件中采取了灰度級(jí)線性拉伸和偽彩變換的算法將原始數(shù)據(jù)進(jìn)行處理，從而使得對(duì)比度明顯增強(qiáng)，得到了清晰的紅外圖像，最終可以達(dá)到實(shí)時(shí)監(jiān)控和探測(cè)的目的。 本項(xiàng)目軟件人機(jī)界面友好，以觸摸屏的方式進(jìn)行操控，在圖像的實(shí)時(shí)顯示過(guò)程中可以實(shí)現(xiàn)截圖錄像等功能，測(cè)試表明軟件功能完善，，運(yùn)行穩(wěn)定。
[Abstract]:Infrared radiation can be produced by all objects. The intensity of radiation produced by objects at different temperatures is different. Infrared detectors can detect the intensity of this radiation and generate infrared images. The infrared image of the target is different from the visible image. It is not the contour image that can be seen by the human eye, but the distribution of the surface temperature of the target. Infrared thermal imaging is to transform the temperature distribution of the target surface which can not be seen directly by the human eye into a thermal image which can be seen by the human eye. On the premise of mature infrared imaging technology, this project uses vanadium oxide as infrared detection material, corresponding drive circuit and analog-to-digital conversion circuit / USB module / OMAP3530 embedded system as hardware platform, and adopts cross-compiling method under Linux environment. A software system with perfect function is developed by using QT, including infrared image real-time display, video recording, screenshot and so on. This software is built in PC Linux system arm cross-compile environment to generate executable code, and then run in OMAP3530 embedded system. In this project, USB data line is used to transmit the target temperature information detected by the front-end infrared detector to the embedded system, which is displayed in the form of video. When the temperature of the target is not different from the background temperature, the contrast will be very low, and the environment and the noise of the circuit will result in the raw data will not be conducive to observation, in order to improve this defect, In the software, gray level linear stretching and pseudo-color transform are used to process the original data, which makes the contrast obviously enhanced, and the infrared image is clear, which can achieve the purpose of real-time monitoring and detection. The software of this project is friendly in man-machine interface, controlled by touch screen, and can realize the function of screenshot and video in the process of real-time image display. The test shows that the software has perfect function and stable operation.
