Description
Technical field
The invention belongs to engineering surface measuring technique and apparatus field thereof, be specifically related to a kind of small vestige of various engineering surfaces and workpiece such as bullet or instrument that is used for and measure, and possess contacting and non-contact type dual-purpose surface roughness measuring systems of contact and contactless two kinds of metering systems.
Background technology
The measurement of vestige generally adopts the method for digital photography to obtain the two-dimensional image of the amplification of article vestige to be measured, because small vestige is three-dimensional, the machinery wiping takes place for generally relevant parts and object under test surface draws and stays, often be depression, stereo structure, its shape and fine feature all are distributed in three dimensions, so two-dimensional image can't provide the complete description of vestige.For example bullet is being carried out vestige when measuring, vestige plane picture two-dimensional measurement instrument commonly used extracts the land border, and what relied on is the variation of edge gray-scale value, and there is bigger error in the true form that its gray-scale value can not reflecting edge.In addition, conventional vestige plane picture two-dimensional measurement instrument can not fully write down the fine feature of object under test, can not fully show the fine difference of object under test.
The three-dimensional measurement technology is emerging engineering surface metering system, it requires surveying instrument vertical survey and horizontal survey scope bigger, especially horizontal scanning scope should be at several millimeter or bigger, so as the comprehensive assessment table and shape error, surface wave temperature and surfaceness relation and to the surface of the work Effect on Performance.The employed instrument that is used for the engineering surface topography measurement adopts the diamond stylus contourgraph of contact measurement method to occupy main status at present, and this is because contact pin type instrument office has reliable, easy to operate, the advantages of cheap price of measurement.But, this diamond stylus contourgraph has two main shortcomings: this quasi-instrument belongs to instrument with contacts on the one hand, there are certain ergometry in contact pilotage and surface of the work, and increase along with the increase of range, sharp diamond stylus is meeting defective work piece surface under certain gaging pressure, and influences the authenticity of measurement result.Simultaneously, contact pilotage can be damaged easily in measuring process.Therefore, for some soft metals, biochemical material, rubber surface, and the surface that contains information and ultraprecise processing work, generally should not adopt this kind mode and instrument to measure, on the other hand, be subjected to the influence of measuring head radius, shape, ergometry and measuring head dynamic property, contact pin type apparatus measures speed is slow, generally be about 1mm/s, particularly in the measuring three-dimensional morphology process, need to consume the too much time, thereby introduce the error that temperature drift brings.
In order to overcome the above-mentioned shortcoming of contact measurement method, contactless measurement based on various measuring principles is developed rapidly, this method can realize the nondestructive measurement of surface topography and evaluation, and help to improve measuring accuracy and measuring speed, therefore be subjected to people's extensive attention and widespread usage.Topography measurement for engineering surface, illuminant-pointer type contourgraph based on the focusing-detection principle is the instrument of standing employing, yet this contourgraph is had relatively high expectations to the cleanliness of surface of the work, the degree of tilt of surface of the work has bigger influence to measurement structure, and also there is influence in the reflectivity of workpiece material to measurement result.
And in the engineering survey practical operation, it is very diversified producing the surface that needs to measure with research, need purchase at different measured surfaces, use different surveying instruments, then can't carry out correct measurement and evaluation for the diversified measured surface of same workpiece for measurement.
Adopt the formation of the vestige of three-dimensional measurement technical research bullet/instrument, Changing Pattern is also analyzed and is checked, can be used for distinguish sending out and variety of gun and instrument are penetrated in identification, thereby provide the evidence of solving a case, for judicial department quick, track down important cases such as gunslinging accurately strong support and scientific basis are provided, also can be used for checking firearms simultaneously, the performance condition of bullet, but because there are above-mentioned defective in existing contact measuring instrument and non-contact measurement instrument, and can't carry out respective detection result's contrast, therefore can't proofread and correct two kinds of measured deviations that measuring instrument produced.
