Description
Technical field:
The present invention relates to field of measuring technique, refer in particular to a kind of measuring method.
Background technology:
In the prior art, generally be the measuring point that adopts single-lens mobile capture measured object, and carry out the virtual construct measured object, thereby obtain the plane of measured object or the technical parameter of solid in conjunction with micro computer.Yet in actual measurement, moving lens is quite time-consuming, bothersome, and whenever moves a camera lens and all need to focus on adjustment, and efficiency of measurement is low.
This case is to propose on the patented technology basis that is had before the applicant, utilizes the measuring technique among the patent ZL02248568.6 further to propose this measuring method.
Summary of the invention:
The object of the present invention is to provide a kind of multi-lens measurement method, it overcomes the defective of existing single-lens measurement, and easy to operate, measuring speed is fast.
For achieving the above object, the present invention adopts following technical scheme to realize:
Multi-lens measurement method, this method system adopts a plurality of measurement camera lens permutation and combination to measure, and comprises the steps:
(1), with the different measuring site distribution of a plurality of measurement alignment lens measured objects, fix each after adjustment is good and measure camera lens;
(2), remove measured object, and insert a mesh coordinate plate, make up a coordinate system, the focus of measuring camera lens more than the step (1) is a corresponding coordinate respectively in this coordinate system then, is designated as reference point and stores in computer;
(3), remove the mesh coordinate plate, the measured object that another is similar is put into measuring table, at this moment, a plurality of measurement camera lenses are focused on measured object automatically, obtain the actual coordinate at the actual measurement position of measured object respectively with the reference coordinate interlock micro computer of measuring camera lens, this actual coordinates by its with reference point that institute corresponding camera lens is determined in step (2) between the relation conversion definite;
(4), the actual coordinate virtual construct that obtained according to step (3) on micro computer goes out the face profile or the stereo profile of measured object, obtain the actual parameter of measured object thus, and be stored in the micro computer;
(5), step (3), (4) repetitive operation promptly realize similar measured object measure batch.
Measuring method provided by the present invention is to replace single-lens moving by many camera lenses, reduce the work of mobile and focusing, for measuring with a kind of measured object, only need once to move and focusing operation, improve measuring speed and efficient thus and eliminate the machine error that produces because of moving.
The present invention adopts the measuring technique of mesh coordinate plate to cooperate, and accuracy of measurement is higher.
The present invention measures as face profile applicable to plane, measurement in space, and concentricity is measured, three-dimensional inclined-plane and cambered surface measurement etc., and wide application effectively promotes the development of measuring technique.
Description of drawings:
Accompanying drawing 1 is implemented synoptic diagram for one of the present invention;
Accompanying drawing 2 is its two enforcement synoptic diagram of the present invention.
Embodiment:
Multi-lens measurement method provided by the present invention is to adopt a plurality of measurement camera lens permutation and combination to measure, and comprises the steps:
(1), the different measuring site distribution of a plurality of measurement alignment lens measured objects, fix each after adjustment is good and measure camera lens;
(2), remove measured object, and insert a mesh coordinate plate, make up a coordinate system, the focus of measuring camera lens more than the step (1) is a corresponding coordinate respectively in this coordinate system then, is designated as reference point and stores in computer;
(3), remove the mesh coordinate plate, the measured object that another is similar is put into measuring table, at this moment, a plurality of measurement camera lenses are focused on measured object automatically, obtain the actual coordinate at the actual measurement position of measured object respectively with the reference coordinate interlock micro computer of measuring camera lens, this actual coordinates by its with reference point that institute corresponding camera lens is determined in step (2) between the relation conversion definite;
(4), the actual coordinate virtual construct that obtained according to step (3) on micro computer goes out the plane or the stereo profile of measured object, obtain the actual parameter of measured object thus, and be stored in the micro computer;
(5), step (3), (4) repetitive operation promptly realize similar measured object measure batch.
In this method, a plurality of measurement camera lens permutation and combination also are positioned at the different measuring position of measured object, are equivalent to single-lens along the repeatedly mobile effect of measured object.When carrying out identical measurement for same class measured object, the present invention only need to each measure camera lens once focus on positioning instant can, more convenient operation in, effectively improve measuring speed and elimination because of the mobile machine error that produces.
Embodiment 1:
As shown in Figure 1, the plane parameter of the "T"-shaped workpiece shown in the survey sheet, at first be to take out a model workpiece (the model workpiece can take out arbitrarily at all workpiece), the model workpiece is placed on the measuring table 1, the different measuring site distribution of a plurality of measurement alignment lens measured objects (model workpiece) is fixed each and is measured camera lens after adjustment is good; Then remove the model workpiece, and on measuring table 1, insert a mesh coordinate plate 2, make up the frame of reference according to mesh coordinate plate 2, at this moment, the focus of a plurality of measurement camera lenses is then established out a coordinate respectively in this coordinate system, be designated as reference point and store in computer; This reference point is a reference point, is used for the actual coordinate that other measured object is measured in conversion; Measure camera lens and be connected, realize data acquisition and conversion, be stored in the micro computer as adopting the CCD camera lens to catch and to obtain coordinate with micro computer.Remove mesh coordinate plate 2 subsequently, another measured object is put on the measuring table 1, measured object is provided with according to the location and puts into, and the position can once fall.The location is provided with can adopt as structures such as anchor clamps and realizes, mainly is to make things convenient for measured object to put between measurement zone accurately.The a plurality of measurement camera lenses that before fix focus on simultaneously the measured object of putting into want sites measured or about, obtain the actual coordinate at the actual measurement position of measured object respectively by the reference coordinate linkage micro computer of measuring camera lens, this actual coordinates by its with reference point that institute corresponding camera lens is determined between the relation conversion definite; The last face profile that goes out measured object on micro computer according to the actual coordinate virtual construct that is obtained obtains the actual parameter of measured object thus, and is stored in the micro computer; Take out at last and surveyed workpiece, put into next workpiece again on measuring table, repetitive operation promptly realizes similar measured object measure batch.
Many camera lenses are location survey simultaneously, need not to move, and greatly improves measuring speed, for large batch of measurement, can reduce or remit the work that repeats mobile and focusing, reduces labour intensity, also effectively eliminates the machine error that produces because of moving, raising measuring accuracy.
