Description
Technical field
The present invention relates to a kind of image measuring system, relate in particular to a kind of method of adjustment of image of 2.5 dimension image measuring systems.
Background technology
The development of measuring technique is that origin stream is long, and human after the demand that tolerance has been arranged, measuring technique develops with regard to being accompanied by human development.From simple ruler, people are developing different surveying instruments always, to adapt to different measurement demands.And, be accompanied by the progress of science and technology, the requirement of measuring technique is also constantly being improved the especially requirement of precision aspect.For this reason, people also at the instrument of constantly improve measuring with should this demand, even lead-in light, sound, electric principle.Have in order to measure a certain project, need to adopt very complicated surveying instrument, can satisfy the demand.
Though generally the measuring technique of Shi Yonging can obtain the high measuring condition of precision, obtain suitable low of the efficient of object survey data, when carrying out a large amount of objects with large enterprise when measuring, adopt aforesaid way to measure and can produce production bottleneck unavoidably.Therefore in people's the production run, the image of object is obtained in utilization, the image of handling object then obtains the dimensional data of object, can enhance productivity greatly like this, but existing disposal system only can be handled the object image that is obtained by custom-built machine, thereby makes the greatly limit of range of application of this kind system.
Because obtaining the mode of the electron image of object at present has a lot, most common form includes the image that utilizes digital camera to obtain object, therefore, in order to enlarge the range of application of image technology, the object image that needs a kind of system can handle all styles of obtains the survey data of object.
Along with development in science and technology, measuring accuracy to various workpiece and part is more and more higher, requirement to surveying instrument also is more and more harsher, and image measurer is the tremendous development to traditional measuring technique, is the product with traditional optical projection and computing machine perfect adaptation.Image measurer is a new term in current industrial detection and the field of measuring techniques, and what its was represented is that numerical digit science and technology is dissolved in industrial detection and metering, carries out the advanced measuring technique of space geometry computing.
The image measurer Survey Software is applicable to two measurement of coordinates to be all surveying instruments (the two-dimensional measurement instrument that contains CCD, grating chi annex) of purpose, and industries such as machinery, electronics, instrument, plastic cement, five metals, spring, wiring board, mould are extensive use of.The hardware of image measurer itself (CCD, grating chi) is transferred to the image that can capture in the data collecting card of computer by USB or RS232 data line, light signal is converted into electric signal, by the imaging on computer monitor of image measurer software, measure fast on computers with mouse afterwards by the operator.Above operation substantially several ten thousand/second finish, so can regard him as real-time checkout equipment, perhaps narrowlyer can be called kinetic measurement equipment.If the computer configuration conforms to requirement, Survey Software can never produce the picture lag phenomenon.It can read the displacement numerical value of optics chi fast, and by being based upon the software module computing on the space geometry basis, moment draws desired result; And on screen, produce figure, and carry out the contrast of figure shadow for the operator, thus the deviation of resolved measurement the possibility of result existence intuitively.Everything is all finished in front in real time in the Computing ability that today is powerful, and the operator can't discover.Thisly can utilize CCD numerical digit image,, satisfy the complicated exact instrument of measuring needs and be only truly image measurer by the computer software computing.
Summary of the invention
At above-mentioned requirements, the purpose of this invention is to provide the method for the adjustment of image of 2.5 dimension image measuring systems, when different object lens multiplying power, can accurately calculate the size of screen enlarged image, accurate when measuring element for catching at screen area.
To achieve these goals, technical scheme of the present invention is that the method for the adjustment of image of 2.5 dimension image measuring systems may further comprise the steps:
A, get standard correcting piece, choose a circle near 1/4 screen size;
B, travelling table make the horizontal line left side of circle to cross curve;
C, click image adjustment then, or the right button of clicking the mouse is clicked image adjustment and is carried out correct operation in popup menu;
E, preservation image, the file name of input correction data is finished correction.
In a preferred embodiment of the present invention, described carrying out needs to carry out earlier the setting of image video before the adjustment of image.
In a preferred embodiment of the present invention, the setting of described image video comprises: the setting of sampling number setting, display mode, video setting and brightness, colourity, contrast, sharpness, saturation degree.
In a preferred embodiment of the present invention, video can be saved as the document of Bmp form among the described step e, also the Bmp picture can be joined in the video form.
In a preferred embodiment of the present invention, described after the user has loaded picture, video be started and just the video active state can be entered.
In a preferred embodiment of the present invention, need carry out four step pixel corrections when image adjustment carries out correct operation among the described step c.
In a preferred embodiment of the present invention, described in the image adjustment process, can cancel operation in due order during the step mistake.
The present invention is the method for the adjustment of image of 2.5 dimension image measuring systems, and the adjustment of image purpose is the size that can accurately calculate the screen enlarged image when different object lens multiplying power, and is accurate when measuring element for catching at screen area.
Description of drawings
Accompanying drawing 1 is the process flow diagram of image correcting method in the embodiment of the invention.
Embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present invention is described in detail, thereby protection scope of the present invention is made more explicit defining so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that.
