3. Software features
Introduction to the main functions of the smart measurement software Easson2D
1. Basic functions:
●Cartesian coordinate/polar coordinate conversion ●Absolute/relative/working coordinate conversion
●Metric/English conversion ●Degree/degree, minute, second conversion
●Point/Point Group ●Two-point/multi-point seeking line
●Three-point/multi-point finding circle and arc ●B-spline line
●The distance between two points ●The average distance between two lines
●The distance between dots and lines ●The distance between two circles
●Circular line distance ●The angle and intersection between two lines
2. Special functions
1. The software controls the light source. The upper light source is a four-phase lamp, and the lower light source is a straight light source, which increases the adaptability of the machine.
2. There is no need to adjust the position for measuring the workpiece, and the software provides coordinate translation, rotation, and position.
3. Mark/move the size directly in the image and geometric area. Straight line trimming and extension function.
4. Geometry zone points, lines, circles/arcs and straight line endpoints, midpoints, circle centers and quadrant points are automatically captured.
5. Adjust the CCD parameter settings to improve the self-adaptive force; remove the burr function to obtain the measurement data correctly.
6. Use the image tool to quickly and automatically grab the boundary points of the basic geometric contours, and directly fit the lines, circles, and arcs.
7. The workpiece in the measurement area is zoomed in and outputted by the camera and converted into (.bmp, .jpg).
8. Measurement data output, converted into WORD (.doc), EXCEL (.xls).
9. SPC function, directly output control chart, process capability index, and convert it into WORD, EXCEL
10. Direct output of mechanical graphics in .dxf format to realize 2D reading function and seamless connection with AutoCAD and other software.
11. Can be transferred to .DXF format files, and compared with the actual workpiece or measurement graphics. And you can directly pick two points in the image area to get the error measurement value.
12. Provide in-plane straightness, roundness, and angle analysis for effective quality inspection
13. The accuracy of the machine is compensated to improve the measurement accuracy.
14. The software can measure multi-deformation, groove shape, arc chamfering and virtual measurement.
15. The 2.5D measurement software can be upgraded, with functions: slope, height, sphere, cylindrical measurement, etc.
16. Re-measurement function: This function can re-change the measurement method, lighting, magnification, etc., for the elements that have been measured, and then refresh the measurement data, and the related element data will also be refreshed (such as: two-line construction distance, if If one of the lines is re-measured, the distance element data will also be refreshed).
17. Modify, edit and view the edge-seeking status: the software can modify and edit the edge-seeking range, light source brightness, magnification, etc. of any measurement element. You can also view the edge-finding status of a certain element measured before (including the position of the edge-finding, the brightness of the light source used, the magnification and the original point taken, etc.), so that the user can control the status of the whole process of measurement.
4. Machine characteristics
The main body of the fuselage is made of high-precision natural granite, which has stable temperature characteristics and anti-aging deformation ability to ensure the stability of measurement and the accuracy of long-term use.
All Yixin's optical image measuring instruments are equipped with the F-1 high-precision full-closed-loop automatic zoom optical lens developed by our company as standard, with high performance and ultra-low distortion to ensure the accuracy of measurement.
High-precision fully closed loop automatic zoom optical lens
The principle of telecentric optics: adopting the optical design of parallel light path, the size of the object image will not change with the distance from the lens, causing the effect of perspective to produce additional measurement errors.
Automatic zoom optical telecentric lens (Telecentric), professionally manufactured by Yixin, is a lens specially designed to correct the parallax of traditional lenses. It can be within a certain object distance range, so that the image magnification will not vary with the object. The distance varies, which is a very important application when the measured object is not on the same surface.
The aperture is a device used to control the amount of light passing through the lens and entering the photosensitive surface of the body. Specifically, if the brightness is high, it can shrink to reduce the total amount of light passing through; on the contrary, if the light is very weak, it can be Make it larger to allow more light to enter. The larger the aperture, the smaller the depth of field; the smaller the aperture, the greater the depth of field. The farther the working distance, the greater the depth of field; the closer the working distance, the smaller the depth of field
F1 High-precision, fully closed-loop, automatic zoom telecentric lens The features are as follows:
Adopt the high-precision, high-resolution ring-type grating ruler specially developed and designed by our company for F-1 for full closed-loop position feedback
High resolution, fully closed loop position feedback, avoiding the repetition error of image multiples caused by gear transmission gap, greatly improving the repeatability of the whole machine measurement.
The resolution of the ring grating is 20 times higher than that of the previous generation zoom lens.
Yixin telecentric lens VS non-telecentric lens
The use of non-telecentric lenses for imaging will produce perspective artifacts and bring test errors.
Use a telecentric lens to correct the image of the light source without distortion and improve the measurement accuracy.

1.1 Acceptance of equipment
The acceptance of equipment is divided into two stages, namely: the first and final acceptance, and the method of acceptance shall be carried out in accordance with the technical agreement reached by both parties.
1.1.1 The first acceptance: After the equipment has passed the factory inspection and acceptance, after the equipment is delivered to the buyer’s project site, the relevant personnel of the buyer and seller jointly open the box and inspect the goods; if there are problems such as shortage of goods, quality, damage, etc., detailed records should be made. The seller will first immediately and unconditionally replace or make up for the buyer, and then check the reason and hold the responsible person accountable. After no doubt, the first acceptance was passed. The seller also provides the test report and product qualification certificate before leaving the factory;
1.1.2 Final acceptance: After the installation and commissioning of equipment and materials are completed and the acceptance criteria are reached, the buyer and seller shall send personnel to jointly check and accept the goods. Upon confirmation by the buyer and the seller, the final acceptance shall be qualified.
