Description
Technical field
The utility model relates to the real-time thermometric thermal imaging system of a kind of triple channel.
Background technology
In forging commercial production, often use television camera or thermal imaging system to observe the stove combustion position, experienced operative employee judges the temperature of burning, material temperature etc. according to the color of television image.This kind judges that human factor is a lot, science very not, and judged result varies with each individual often, and different because of factory, this stability to production technology, consistance are brought very big influence.
The utility model content
The purpose of this utility model provides the real-time thermometric thermal imaging system of a kind of triple channel, increase by two passages and compare radiation temperature measurement, record a width of cloth temperature pattern simultaneously, measure temperature accurately, overcome the deficiency of using television camera or thermal imaging system to observe the stove combustion position.
The purpose of this utility model is to be achieved through the following technical solutions:
The real-time thermometric thermal imaging system of a kind of triple channel, comprise object lens, visible light eyepiece, visible light colour TV camera, between object lens and visible light eyepiece, be provided with Amici prism, be respectively equipped with broadband imaging system and arrowband imaging system in both sides up and down at Amici prism, described broadband imaging system comprises broad band pass filter, broadband eyepiece and CCD chip, and described arrowband imaging system comprises narrow band pass filter, eyepiece and CCD chip; The Amici prism right side is provided with visible light eyepiece and visible light colour TV camera.The utility model adopts an Amici prism in common pick-up lens design, tell other two light paths and image in two shooting CCD chips respectively, wherein one tunnel spectrum is at the 0.8-1.05 micron, be called the broadband, the spectrum on another road is at the 0.9-1.0 micron, be called the arrowband, this 2 light path adds common visible light, and totally three road video images have same visual field.
The beneficial effects of the utility model are: used a triple channel camera lens, use three cameras simultaneously, one is individual to be exactly common colour imagery shot, two is broadband and arrowband stylus in addition, visible light coloured image, wide spectrum picture and narrow spectrum picture three road images are from same object lens, same visual field, wide, arrowband image is from same sequential, same clock, picture point overlaps fully, the Temperature Distribution that has reflected combustion field objectively, exactly is for the fiery thermal imaging system of seeing commonly used has increased a real-time temperature field measurement function.

Embodiment
As shown in Figure 1, the real-time thermometric thermal imaging system of triple channel described in the utility model, comprise object lens 1, visible light eyepiece 9, visible light colour TV camera 10, between object lens 1 and visible light eyepiece 9, be provided with Amici prism 2, both sides be respectively equipped with broadband imaging system and arrowband imaging system at Amici prism about in the of 2, described broadband imaging system comprises broad band pass filter 3, broadband eyepiece 4 and CCD chip 5, and described arrowband imaging system comprises narrow band pass filter 6, arrowband eyepiece 7 and CCD chip 8; Amici prism 2 right sides are provided with visible light eyepiece 9 and visible light colour TV camera 10.The utility model adopts an Amici prism in common pick-up lens design, tell other two light paths and image in two shooting CCD chips respectively, wherein one tunnel spectrum is at the 0.8-1.05 micron, be called the broadband, the spectrum on another road is at the 0.9-1.0 micron, be called the arrowband, this 2 light path adds common visible light, and totally three road video images have same visual field.
As shown in Figure 2, pass by next light by broadband light among Fig. 1, through broad band pass filter, focus on the CCD focal plane, the light signal on this CCD is converted to charge signal, through the pulsed drive of sequential circuit, electric charge enters the CCD chip, obtain amplifying and handling, become digital signal through AD converter then, enter extensive gate array device.For the explanation of arrowband light path roughly the same.Exist the picture information in the extensive gate array device to carry out video transmission by prior art, transmission manner adopts optical cable, is equivalent to the function of one three road fiber optic.The characteristics of signal Processing are that the driving of broadband and arrowband video camera all is identical with A/D collection clock, and the image point that guarantees to gather obtains result exactly at the synchronization same position for asking ratio later on.Colored thermal imaging system video camera also becomes digital signal through behind the video decode.These three digital video signals are transferred to the video reception card of Central Control Room according to three tunnel common video transmission technologies by optical cable.
At this end of video reception, use up-to-date CPI-E interface, make three road videos adopt the DMA method, enter computing machine fast.By application software, on graphoscope, obtain the most basic image of two width of cloth: visible coloured image, false colored temperature pattern.This temperature pattern is to obtain by the ratio computing to broadband and narrow band signal, and realizes false colour by palette,
The method than radiation is adopted in temperature survey, and so-called is exactly the ratio that calculates the radiant quantity of the radiant quantity of a wide spectral range and a narrow spectrum segment than radiation, and this ratio has relation with the temperature of object, and ratio in view of the above just can be tried to achieve the temperature of object.This influence that can eliminate attenuation factor such as dust to measurement result than method of radiating, it doesn't matter again for the radiation coefficient of its result and object, thereby can obtain the temperature of object exactly.This patent utilizes the data of broadband video camera and the data of arrowband video camera all to be proportional to the radiation value that is received, ratio between two promptly is the ratio of the radiation of two wave bands, utilize same clock in time, same scanning sequence is sampled, the data of being gathered are synchronizations, the radiation value of same image point is so ratio has accurately reflected the temperature value of this image point.
