One of the questions of image measuring instrument
1, if the image is too small, can be applied to monitor,but can not change the image area, and takes themagnification lens like range and relationship. In the same lens conditions, also affected by the CCD chip size.
2, some people think that the image measuring instrument picture area is too small, not what the actualsignificance, to shoot took the entire piece, this view is one-sided. Because we are using technology stack,each picture of computer memory, processing speed will be slow down, taking pictures is the main purpose is toreflect the local characteristics of the workpiece, field of view or may be appropriate to change the lens, in order to increase the shooting area. At present, the use oflens magnification between the images of 28 times -180 times, the area of image representation of object sizeswere between 9mm × 7mm and 1.4mm × 1.1mm.
The difference between the 3, optical amplification andimage magnification is: optical amplification refers tomultiple CCD objects through the eyepiece magnification.Image amplification refers to the actual image and objectmagnification. The difference between them lies in theamplification in different ways, the former is the structure through the optical lens to zoom in, no distortion. The latter is within the CCD processor, each pixel in the image area increases, so as to achieve the purpose ofamplification, only belongs to the category of processing image magnification.
4, image and the work table to move in the opposite direction, CCD can be loaded back 180 degrees can be.
5, automatic catch (measurement) round, why the showis elliptic or two lines. Possible reasons are as follows: X,Y axis error possible optical ruler reading and readingdirection; compensation file may have problems; readingcard may not normal; correction error linear.
6, the geometry and image to be opposite? The reason may be: reading card parameter setting is not correct,check the shaft readings is consistent with the direction of movement, if the opposite when you adjust the parameters.
7, image window is blue, the reason may be: image line may not plugged; CCD may not have power supply;control box power supply may not open.
Measuring tool and measuring tool 8, deburring datawhy not?
Answer: automatic measurement to find the point is the black and white boundary edge points. The burr isscanning the contour points, working principle is different.Even if the data are poor, should not exceed theallowance.
9, image measuring instrument can measure plane?
Answer: only rely on image measurement is not measuring flatness, if with a composite type measuringprobe or laser measuring head can be measuredflatness.
10, in the image window, what are the benefits ofdimensioning parts image?
Answer: in the window, mark again after taking picturescan give customers the most direct reference.
The sensitive range 11, automatic edge searching the Is it right? Bigger is better? Why?
Answer: No, if the sensing range is too big, the edge may be taken into neighboring characteristics.
Re. Re annotation.
Why cross line 12, the software does not show?
Answer: the possible reasons are as follows: the cross line function is not open. From the geometric measurement and image measuring click the drop-down menu to open the cross line button or reinstall the software.
13, the interface of the software cannot display all?
Answer: may be the display resolution setting bad; set the display resolution of 1152 x 864.
14, why the test piece small, there will be a polygon?
Answer: software "image measurement" drop-down menu in the "instant drawing set" error, re check the "image measurement" drop-down menu in the "instant drawingset". And reset the graphics resolution.
15, why the ellipse measured round?
Answer: may not be linear correction; grating ruler may drop number of hops. To do the linear correction or replacement of the grating ruler or counting cards.
16, open the pedal switch, why software has automaticmanagement?
Answer: may be bad contact pedal switch.
