In order to overcome the defect that an existing method of conducting fracture ductile fracture area percentage measurement through a film type camera is not suitable for radioactive impact specimen measurement, the invention provides an impact specimen fracture picture taking device. The impact specimen fracture picture taking device comprises a stepping motor control system, a camera control and digital image collecting system, a stepping motor, an industrial digital camera, a continuous zooming and amplifying lens, a camera lifting platform, an annular LED visual light source, a pull rod, an impact specimen clamping base and a clamping base rail. The picture taking device is suitable for measuring the impact specimen fracture ductile fracture area percentage, and measurement data can be easily stored; the camera shooting quality of the appearance of a fracture can be directly determined in the measurement process, and adjustment can be directly conducted when imaging is not clear; the measurement accuracy for the impact specimen fracture ductile fracture area percentage is high, and data accuracy is high; the picture taking device is easy to operate in the use process, and long-distance measurement of an impact specimen with the large radioactive dosage can be achieved.
Description
Technical field
The present invention relates to a kind of photogrammetric apparatus, particularly a kind of impact specimen fracture photographic means.
Background technology
In impulse test, the fracture ductile rupture area percentage of impact specimen is important tests data.Current, the major equipment of measuring for fracture ductile rupture area percentage is film type camera.Concrete measuring method is: with film type camera, fracture is taken a picture, amplify and wash into the measurement of the laggard row fracture of film ductile rupture area percentage.Adopting film type camera to carry out the measurement of fracture ductile rupture area percentage has the following disadvantages: one, and measurement of correlation data are difficult for preserving; Its two, the shooting quality of fracture apperance can not directly be determined, if photo imaging is unintelligible, can only re-start photograph, this will produce a large amount of additional workload for radioactivity fracture surface of sample.Its three, measuring accuracy is lower, the accuracy of data is lower; Its four, in the time that the radioactive dosage of sample is larger, be unfavorable for operating personnel's operation.
Therefore, to adopt film type camera to carry out the problems referred to above that the measurement of fracture ductile rupture area percentage exists in order overcoming, to need a kind of new measurement mechanism of exploitation badly and measure with the fracture ductile rupture area percentage that is applicable to radioactivity impact specimen.
Summary of the invention
Carry out for solving existing employing film type camera difficult preservation of measurement data that the measurement of fracture ductile rupture area percentage exists, the shooting quality of impact specimen fracture apperance can not directly be determined, the accuracy of measuring accuracy and data is lower, be unsuitable for the deficiencies such as the measurement of radioactivity impact specimen, the invention provides a kind of impact specimen fracture photographic means.
This device comprises step motor control system, camera control and digital image collection system, stepper motor, industrial digital camera, continuous zoom enlarging lens, camera hoistable platform, annular LED vision light source, pull bar, impact specimen deck, deck track; Described step motor control system, for control step motor, can make industrial digital camera move up and down in vertical direction along camera hoistable platform under the driving of stepper motor; Described camera control and digital image collection system are for controlling the operation of industrial digital camera and the collection of digital image; Described continuous zoom enlarging lens is connected with industrial digital camera, and continuous zoom enlarging lens lower end is connected with annular LED vision light source; Annular LED vision light source below is provided with impact specimen deck and deck track, and impact specimen deck is connected with pull bar, and under the push-and-pull of pull bar, impact specimen deck can be along deck track by to-and-fro movement between below sample introduction position and annular LED vision light source.
The using method of impact specimen fracture photographic means of the present invention is as follows: the first step, impact specimen is installed on impact specimen deck in sample introduction position, pull pull bar, make impact specimen deck along deck rail moving to annular LED vision light source below, and make impact specimen fracture aim at continuous zoom enlarging lens; Second step, adjusts industrial digital camera position in vertical direction by step motor control system, adjusts the enlargement ratio of camera parameter and continuous zoom enlarging lens by camera control and digital image collection system simultaneously, obtains required image-forming condition; The 3rd step, by camera control and digital image collection system acquisition digital image, measures gathered digital image, obtains impact specimen fracture ductile rupture area percentage.
Impact specimen fracture photographic means of the present invention is suitable for the measurement of impact specimen fracture ductile rupture area percentage, and measurement data is easy to preserve; In measuring process, can directly determine the shooting quality of fracture apperance, when imaging is unintelligible, can directly adjust; The measuring accuracy of impact specimen fracture ductile rupture area percentage and the accuracy of data are good; When use operation comparatively simple, can realize the telemeasurement of the impact specimen that radioactive dosage is larger.
