Abstract
The utility model discloses a round target of image measuring instrument error -detecting, including target board and the figure of printing in target board centre of surface position, the figure includes places the same circular in the square in two sets of in, and two circularly adopted printing opacity and not transparent material printing respectively, the circular shape diameter is 0.5 -20mm, and the length of side of square is 1 -23mm, the utility model discloses a jumbo size image measuring instrument has been solved to the target can't interimly measure the problem of surveying the error, and messenger's detection is convenient more, the result is more credible.
Description
Technical field
The utility model relates to two-dimensional standard, for the detection of sizing, image measurer gauge head detecting error, two-dimensional detection error, zoom detecting error, and the particularly round target of a kind of image measurer error-detecting.
Background technology
The detecting error of image instrument directly affects final measurement result, so no matter be gauge head detecting error, two-dimensional detection error or zoom detecting error, for the very important index all judging complete machine quality image measurer.And before the detection of these three indexs only being relied on to the circle of a diameter 5mm in comprehensive model, precision is low, operation inconvenience, cannot realize the detection of the powerful detecting error of large scale, also cannot realize the detection of two-dimensional detection error.
Summary of the invention
In order to overcome above-mentioned defect, the utility model provide a kind of high precision, fast, stage by stage detecting instrument detecting error, disposablely can complete the round target of image measurer error-detecting of two-dimensional detection error.
The utility model in order to the technical scheme solving its technical matters and adopt is: the round target of a kind of image measurer error-detecting, comprise target plate and be printed on the figure of target plate centre of surface position, described figure comprises two groups of identical circles be built in grid, and two circles adopt printing opacity and light tight material to print respectively, the diameter of described circle is 0.5-20mm, and the length of side of grid is 1-23mm.
As further improvement of the utility model, described target plate surface is provided with many block graphicses, and the spacing between every block graphics is 13mm.
As further improvement of the utility model, described target plate adopts quartz glass to make, and its thickness is 2.3mm.
As further improvement of the utility model, the edge of described target plate adopts chamfering and atomization process.
The beneficial effects of the utility model are: target of the present utility model solves large scale image measurer cannot the interim problem measuring detecting error, make that detection is convenient, result is more credible.
Accompanying drawing explanation
Fig. 1 is one of the utility model structural representation;
Fig. 2 is the utility model structural representation two;
Indicate in figure: 1-target plate; 2-figure.
Embodiment
In order to deepen understanding of the present utility model, below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail, and this embodiment, only for explaining the utility model, does not form the restriction to the utility model protection domain.
Fig. 1 shows a kind of embodiment of the round target of a kind of image measurer of the utility model error-detecting, comprise target plate 1 and be printed on the figure 2 of target plate centre of surface position, described figure 2 comprises two groups of identical circles be built in grid, and two circles adopt printing opacity and light tight material to print respectively, the diameter of described circle is 0.5-20mm, and the length of side of grid is 1-23mm.
As shown in Figure 2, described target plate 1 surface is provided with many block graphicses 2, and the spacing between every block graphics 2 is 13mm.
Described target plate 1 adopts quartz glass to make, and its thickness is 2.3mm.
The edge of described target plate 1 adopts chamfering and atomization process.
Lain against by target disc on work top, adjustment image definition, takes 25 points roughly uniformly to whole circle, adopts the method for spot measurement, with the data fitting Least Square Circle of all 25 measurement points, and then records detecting error.
