Embodiment

For that can be illustrated more clearly that the present invention, now lift preferred embodiment and coordinate attached drawing detailed description as follows.The present invention adds The detection method of work object base specification is suitable for the object of tabular, to judge whether the object meets a base specification, this Locate described base specification, refer to that the object for meeting the base specification can carry out follow-up correction and processing action, and produce The processed finished products gone out have effects that expected.The detection method includes the use of a photographic goods, and conjunction is first chatted bright.

Please refer to Fig.1 and Fig. 2, one embodiment of the present invention be an object 10 by correction object, on the object 10 calmly Justice has four reference points 12, is formed by the both sides extension intersection at each end angle of the object 10；The photographic goods have four Form 20, respectively covering in the drop shadow spread of those forms 20 has the reference point 12, and those forms 20 all define a correction Point 22, and the check point 22 can not be moved relative to the form 20, respectively the reference point 12 in the form 20 and the check point 22 Correspond to each other.

Those forms 20, which respectively define, a coordinate system 24, and respectively the check point 22 defined in the form 20 is in the present embodiment Definition mode for the origin of the coordinate system 24, but the check point 22 is not limited thereto, in other embodiments, the check point 22 can also be disposed other than the position of origin；Since the check point 22 and the reference point 12 are all located on the coordinate system 24, therefore The check point 22 has one first coordinate value (X1, Y1), which also has one second coordinate value (X2, Y2).The respectively ginseng The check point 22 is mutually separated with a distance to examination point 12 naturally on a projection plane with corresponding one, which is the respectively reference One offset distance of point 12；In the preferred embodiment, respectively the offset distance of the reference point 12 can pass through the check point 22 First coordinate value (X1, Y1) and second coordinate value (X2, Y2) of the reference point 12 are calculated through geometry teaching to be learnt.
