Description
Technical Field
The invention relates to the technical field of measurement result standardization in the process of measuring deformation and strain by DIC (digital computer), in particular to a standard speckle spraying device and a standard speckle spraying method.
Background
With the rapid development of national industry, the detection of deformation in mechanical properties is very popular, how to accurately and efficiently detect deformation becomes more and more important, the detection of deformation can be applied to the test of various materials and structures, and DIC technology has the advantages of non-contact, three-dimensional, full-field and the like and is more and more applied. DIC techniques, however, necessarily require placement of speckle on the specimen surface. The manufacturing effect of speckle directly influences the integrity and measurement precision of test data and the consistency of measurement results.
The traditional deformation measurement methods have three types, one is to manufacture speckles in a stamping mode, but the method can only manufacture plane samples, and is complex in operation and limited in use scenes.
For example, patent document CN 106018036 a discloses a method for making speckles on a concrete surface, which includes generating a speckle image, laser engraving a speckle pattern corresponding to the speckle image on a surface of a hard sponge plate, providing a stamp, fixing the hard sponge plate on a bottom plate of the stamp to form the speckle pattern, coating a pigment on the surface of the hard sponge plate to form a color coating surface, and pressing the color coating surface on a surface of a concrete block to form the speckles on the concrete surface. However, this method can only be used for manufacturing a planar sample, and is complex in operation and limited in use scenario.
The second method is a speckle film covering method, which is to make a film with speckles, stick the film on the surface of a sample, and cover the speckles on the surface of the sample after the film is uncovered. The method has too complicated operation process and very low efficiency. Meanwhile, the requirement on operators is extremely high, and the speckle manufacturing can fail due to slight carelessness.
For example, chinese patent publication No. CN 108413888A discloses a speckle coating for strain measurement, which is composed of a light-colored or white organic material film and dark speckles, and the front surface of the coating can be sprayed, printed or made into speckles by other methods. When in use, the back surface of the covering film can be directly attached to the surface of the structure to be detected by means of electrostatic adsorption, vacuum adsorption or using an adhesive and the like. The method has too complicated operation process and very low efficiency. Meanwhile, the requirement on operators is extremely high, and the speckle manufacturing can fail due to slight carelessness. This method cannot be widely used.
The third method is to adopt a manual paint spraying method, and manufacture speckles by manually spraying the paint against a sample through automatic paint spraying, and the method has high requirements on personnel, and the speckle results of each spraying cannot be unified, so that the measurement results are not consistent, and further the DIC measurement cannot be standardized.

In view of the above, the invention provides a standard speckle spraying device, which selects standard speckles digitally, stores the standard speckles, and then directly and automatically sprays the standard speckles to the surface of a tested sample based on the standard speckles; one set of system can just match the tested appearance of multiple specification, and the operation degree of difficulty is little requires lowly, the spraying is efficient and the uniformity of spraying is strong.
In order to achieve the technical purpose, the invention adopts the following specific technical scheme:
a standard speckle spraying device is used for monocular three-dimensional visual identification calibration of a tested sample strain process, and comprises:
the speckle generation system is used for configuring corresponding standard speckles based on the shape, the motion state and the appearance of the tested sample;
a speckle storage system in communication with the speckle generation system for storing at least one set of the standard speckles;
the ink jet system is communicated with the speckle storage system and is used for spraying the standard speckles on the surface of the tested sample;
wherein: when the ink jet system and the tested sample are in at least one relative position, the ink jet system realizes automatic spraying of the standard speckles to the tested sample.
Further, the standard speckle is composed of a background color and a plurality of regularly arranged elements; the background color can be set in an adjustable way; the shape and rendering type of the primitive may be configurable.
Further, the shape and rendering type of the primitive include: diameter, number of sides, void fraction, degree of close packing, and degree of offset.
Further, the resolution of the standard speckle can be set.
Further, the speckle storage system is configured with a memory card slot, and the data information of the standard speckles is stored on the memory card;
the ink jet system comprises a converter, an ink box and a spray gun; the converter is used for reading the memory card and generating a control signal when receiving a spraying instruction; and the spray gun takes the pigment in the ink box based on the control signal and sprays the standard speckles from an outlet in a stepping mode.
Further, the speckle storage system and the ink jet system are integrated on a handheld device.
Further, a battery power supply system is also configured on the handheld device.
Further, the configuration process of the standard speckles is realized based on a graphic setting system; the graphic setting system is configured with a selection interface; the selection interface includes:
the type configuration area is used for selecting the element type, rendering and background color for configuring the standard speckles;

and the speckle display area virtually displays the pattern of the standard speckles in real time based on the configuration selection of the type configuration area, the element configuration area and the graph configuration area.
Further, the diameter of the element, the pattern width of the standard speckle and the pattern length of the standard speckle are all described by the number of pixels.
Meanwhile, the invention also provides a standard speckle spraying method which is realized based on the standardized speckle spraying device and comprises the following steps:
s101: configuring corresponding standard speckles based on the shape, the motion state and the appearance of the tested sample;

By adopting the technical scheme, the beneficial technical effects of the invention comprise one or more of the following:
1. compared with a method for manufacturing speckles in a stamping mode, the method can be flexibly applied to more scenes. Aiming at a large-range sample, the speckle can be manufactured by moving the automatic spray gun without preparing a too large seal. Meanwhile, for a sample with a curved surface shape, a seal method cannot be used, and the method can also be used, so that the method is wider in application range.

The invention has no requirement on operators, can finish the fast speckle manufacturing only by holding the automatic spray gun by the operators, and greatly improves the speckle manufacturing efficiency.
3. Compared with the method for manufacturing the speckles by manual paint spraying, the method can manufacture the standardized speckles. The speckles are manufactured by a method of manually spraying paint against a sample, the method has high requirement on personnel, and the speckle result sprayed each time cannot be unified, so that the measurement result is not consistent, and further the DIC measurement cannot be standardized. The invention adopts speckle image generation software to generate standard speckle images according to different sizes of samples. The speckle image generation software can set the size of the resolution width and the height according to the size of a sample, select the shape of an element, the rendering type and the background color, and then determine the diameter, the number of edges, the void ratio, the close packing degree and the offset of a pattern. A virtual pattern of standard speckles is generated. Because the pattern and the standard speckles to be sprayed onto the sample under test can correspond one-to-one, normalized speckles can be generated.
