A kind of portable image tacheometer
Technical field
This utility model relates to precision measurement apparatus technical field, particularly relates to a kind of portable image tacheometer.
Background technology
Precise measure measuring instrument is mainly used in five metals, electronics, mould, Cellphone Accessories, aviation, wiring board, spring, cutter
The all trades and professions such as tool;Wherein, slide calliper rule, amesdial, height gauge, conventional projector, image instrument, three-dimensional coordinates measurement it are currently mainly used
The apparent size of product is measured by machine equal length measurement instrument.Along with carrying of industrial manufacturing process and precision component size
Height, numerous parts needs part sampling observation the most entirely to examine, and workpeople must put into a large amount of manpower and the time tests product size.
It addition, utilize conventional measurement devices to realize product size detection during, it is generally required to artificially set up
Measuring basis, and be only positioned on platform measurer can be used just now to detect.Due to everyone set up coordinate and take point, line,
Circle mode is different, causes measurement error, arranges all data sheets again and specify in masterplate to company, both delayed after being measured
Time takes efforts again.
It should further be noted that the camera lens object lens multiplying power of tradition radiographic measurement equipment is typically at 0.7-4.5 times, become by CCD
After Xiang, the visual field on computer is about 2-8mm;The slightly bigger product of measurement size must move X, Y workbench to capture product
Product size.Telecentric lens in the market can only measure size in field range, more than the product amount of will be unable to of visual field
Surveying size, helping the principle of image measurer and agent structure to capture image border profile point cloud even if measuring also can only connect,
Proceeding to world coordinate system again be fitted measuring, product just can must measure in the case of ajusting simultaneously.Wherein, existing
The deficiency of Image detection industrially and defect be mainly reflected in following some;
1, can not arbitrarily put product, otherwise program cannot normally read;
2, can deflect during movable workbench situation, and the photo taken cannot accurately read picture displacement
Value;
3, the product more than more than 10cm, basically can not carry out high-acruracy survey again;
4, the product data that different people is measured are different, and the benchmark that mainly everyone sets up is different with capturing picture position
Cause;
5, there is the part of difference in height, need to regulate camera lens height and come clearly.
