Description
Technical field
The present invention relates to a kind of method and device thereof of field of measuring technique, specifically the online method for three-dimensional measurement of a kind of structured light of large forgings and device.
Background technology
Large-scale hot forging is the necessary starting material of many major technologies and equipments, but closes because traditional measurement method is difficult to be applied in its actual processing space, causes in actual production, having to amplify process redundancy.For the process redundancy that reduces to cause due to the shortcoming of measurement means, many contactless online test method are used, and the online detection based on structured light is exactly one wherein.
But, because hot forging surface often exists strong infrared emanation, make the image that camera imaging obtains have strong interference, be difficult to judge the edge contour of forging in image.
Summary of the invention
The object of the invention is to for an above difficult problem, a kind of online hot forging detection method and device based on fluorescence reaction is provided.The present invention is on the basis of traditional structured light device, face structured light projecting device and camera placement fluorescent plate in the behind of detected forging, the light projecting when structured light projecting device is walked around detected forging and is irradiated to after fluorescent plate, form at fluorescent plate surface excitation the light source that is stimulated, by the fluorescent material on allotment fluorescent plate, make to be stimulated the wavelength of light source away from the wavelength of detected forging surface emissivity, be convenient to obtain image clearly.The shaped position of the light source forming owing to being stimulated on fluorescent plate is also that the modulation that is subject to detected forging forms, and therefore can combine with the structure light image on detected forging surface, is convenient to the contour edge of the detected forging of identification accurately.
As shown in Figure 1, in figure, 1 structured light device, 2 is detected forging, 3 fluorescent plates, 4 forge press to basic structure of the present invention.
Accompanying drawing explanation
Fig. 1 is basic block diagram of the present invention.
Embodiment
Illustrate embodiment of the present invention below in conjunction with accompanying drawing
Fig. 1 is basic block diagram of the present invention, and 1 is structured light device (combination of structured light projecting device and camera, what both were fixed is arranged on same support) as shown in the figure, and 2 is detected forging, and 3 is fluorescent plate, and 4 is forge press.
First the structured light that structured light projecting device is launched forms the projected image that is subject to detected forging 2 appearance profile modulation on the surface of detected forging 2, project on fluorescent plate 3 crossing after detected forging 2 and be not subject to light that detected forging 2 stops, on fluorescent plate 3, irradiated fluorescent material is at the projected image that is subject to producing after incident light excites luminous point that wavelength differs from detected forging infrared radiation and forms, and detected forging 2 is received the three-dimensional dimension for measuring detected forging with the image on fluorescent plate 3 by camera simultaneously.
Owing to adopting the principle of fluorescence reaction, can make the image obtaining on fluorescent plate 3 not be subject to the impact of the infrared radiation on detected forging 2, combine with the projected image on detected forging 2, can judge more accurately the edge of detected forging 2, and then obtain measuring more accurately the size of detected forging 2.
Compare traditional mechanism's light three-dimensional measuring apparatus, the method applied in the present invention can more efficiently eliminating the radiation interference of detected forging 2, can be directly installed on forging machinery simultaneously, can provide in real time, accurately the size of detected forging 2, for the raising of forging precision provides reliable detection means.
