Introduction of Software System

Our company has invested in research and development of fast image processing, concurrent algorithm,

precision compensation, system framework and other aspects. We have integrated a set of high-efficiency

and high-precision professional visual inspection system to meet the new demand for high-speed online

full-scale inspection under the industrial environment of 4.0.

In the development process, we cooperate with foreign third-party professional visual software companies

in depth, and can access third-party expansion modules such as high-speed image matching and advanced

image preprocessing, which make the software have extensive non-contact industrial measurement

expansion functions.

Main features:

a. Complete image metrology software functions: including the measurement of all kinds of 2D element points, lines, circles, arcs, Polylines, spline curves;

b. Complete coordinate system, structure and tolerance calculation function;

c. The function of importing and exporting CAD and offline programming;

d. High-precision sub-pixel interpolation and lens distortion compensation function;

e. Target recognition and image matching module (optional function)

f. In collaboration with other professional machine vision companies, we take the lead in introducing

advanced functions such as general machine vision algorithm, image preprocessing, mosaic, morphology,

miscellaneous edge and weak edge recognition, gray level variance, color difference discrimination, image

template, Blob, bar code, outline recognition and comparison in metrology software; (Optional function)

g. Motion measurement module: supports on-line measurement-level high-precision detection of moving objects. (Optional function)

h. Software interface

The main functions of the software are as follows:

1. Image measurement tools

Specifically, it includes the following functions:

Import static pictures

Save pictures

Field of view zooming

Field of View Adaptation

Camera Dynamic Preview and Image Capture

Setting of Measuring Parameters

Point Cloud Tool

Automatic Recognition of Objects and Spline Curve Circle Measuring Tool

Linear measuring tool

Circular measuring tool

Arc measuring tool

Point measuring tool

Extremum Measuring Tool

Rectangular Range Definition Tool

By using the above tools, the measurement of feature elements in camera shooting or static pictures can

be realized. Take the circle tool as an example, the following is an example of measurement: concentric

circle is the range of edge patrol, which can be manipulated by mouse to realize the editing functions of

zooming, translating and defining the direction of edge patrol.

Setting parameters of measurement parameters are detailed:

1.Edge-seeking points: set fixed number of edge-seeking points, or automatically allocate points according to interval points;

2.Edge Search Range: Search Default Range 30 for Finding Boundary Points.

3.Boundary type: black > white; white > black; step point;

4.Side-finding direction: correctable direction; forward or reverse direction.

5.Extremum type: By setting this value, the special functions of measuring the maximum outer diameter/minimum inner diameter and mesh boundary of gears can be realized.

6.Noise filtering: Least squares filtering intensity and Gaussian pre-filtering method can be set to eliminate measurement noise.

7.Miscellaneous edge location: For the edge with strong interference noise, three advanced pre-positioning methods are provided: step gray statistics; dynamic template; static template. The real boundary can be measured effectively for the noisy edges.

8.Sub-pixel algorithm: According to the characteristics of light source, sub-pixel compensation parameters can be pre-set to improve the measurement accuracy;

9.Threshold class parameters: adjustable range of weak edge measurement and threshold 8BA1 calculation

Definition of tolerance: Relevant parameters of all tolerances mentioned above can be defined, such as tolerance name,

theoretical value, measured value, tolerance element, reference element, upper and lower tolerance zone

definition, tolerance calculation type, common algorithm, material definition, etc.

Example

distance tolerance

Default values are used by default

Type: You can choose to calculate the X.Y axis distance

Element Construction Function: The software adopts a construction classification method oriented to construction objectives. Through three clear steps:

1) Selection of one or more geometric elements involved in the construction

2) Choosing the geometric type of the construction target.

3) Choose the method of construction.

Commonly used construction algorithms include least squares fitting, midpoint, midpoint, intersection,

projection, parallel plane, vertical, translation, tangency, key point, mirror, etc., to achieve dozens of

different construction algorithms, covering almost all possible construction types of measurement software.

Taking the two-level menu of two circles to construct straight lines as an example, all possible constructions

can be obtained as follows.

The commonly used 2D geometric construction functions are shown in the following table:

Part coordinate system function:

The system parts coordinate system can be built iteratively. The software can build coordinate system

intelligently and efficiently with one key according to the type and position of the elements in the coordinate

system. It can build coordinate system through point-point class, point-line class, circle-circle class, circle-

line class, line-line class, discrete multi-point fitting, CAD theoretical element-measured element, B-spline

curve. Line fitting and other methods are used to establish the coordinate system of parts needed by users.

2. Control tools:

Through the above tools, such as delay, input, output, circulation, light source, camera and so on, it can

realize linkage with external PLC controller, manipulator, conveyor belt, switch, induction device, light

source, camera, alarm indication, etc. Quickly build online automation application scenarios.

3. Element Attribute Page:

Element attribute pages are used to display the results and attributes of program items, measurement

elements, construction elements, calculation tolerances, hardware controls, etc. Batch output settings and

tolerance definitions of tolerances within batch elements (X, Y, Z, R, D, Form) can be made.

Note: Form tolerance supports straightness, roundness, flatness and curve contour.
