Laser-Vision Linked Measurement

After completing laser-vision offset calibration, Easson2D can link vision measurement positions with laser measurement positions.

You can directly select the position for laser acquisition in the image area. The software automatically moves the machine to the corresponding position based on the calibration result and completes the laser point acquisition.

This method is especially suitable for quickly locating target positions with the main camera and then using the laser to obtain height data at those positions.

1. Establish a Target Point in the Image Area

First, find the position for laser measurement in the image area.

Use the point measurement function to generate a point element at a suitable position.

This point element represents the target position where the laser should acquire data.

2. Perform Automatic Laser Point Acquisition

Right-click the point element just created in the data area or on the element, then select:

Automatic Laser Point Acquisition

Easson2D calculates the corresponding laser measurement position for this image point based on the completed laser-vision offset calibration result.

The machine then automatically moves to the target position and completes the laser acquisition.

3. A Laser Point Element Is Generated Automatically

After the laser point acquisition is complete, the software generates the corresponding laser point element.

Therefore, the entire process can be summarized as:

Select a target position in the image area → Generate a point element → Right-click and select "Automatic Laser Point Acquisition" → The machine automatically moves to the corresponding position → The laser completes point acquisition → A laser point element is generated

This reduces the need to manually move the machine to locate laser measurement positions.

Using Multiple Laser Points for Subsequent Measurement

After automatic laser point acquisition at multiple positions, you can use the generated laser point elements for further geometric calculations.

Fit Height

Select:

2 laser point elements

Then right-click to fit and generate a height result using these two laser points.

This is suitable for comparing the height difference between two positions.

Fit Flatness

Select:

4 laser point elements

Then right-click to fit and generate a flatness result using these laser points.

Therefore, you can also select multiple positions in the image area first, perform automatic laser point acquisition one by one, and finally use the obtained laser points to complete flatness measurement.

Height Measurement Example

To measure the height between two positions:

1. Establish the first point element in the image area.
2. Perform "Automatic Laser Point Acquisition" on this point.
3. Establish the second point element in the image area.
4. Perform "Automatic Laser Point Acquisition" again.
5. Select the two generated laser point elements.
6. Right-click to fit the height.

This lets you quickly specify two laser measurement points through image positions.

Flatness Measurement Example

To select multiple flatness measurement positions through the image:

1. Establish point elements at different positions on the measured surface.
2. Perform "Automatic Laser Point Acquisition" on each point.
3. Obtain at least 4 laser point elements.
4. Select the 4 laser point elements.
5. Right-click to fit the flatness.

This allows you to visually plan the point acquisition positions in the image first, then have the laser complete the actual height data acquisition one by one.

Basic Workflow

Laser-vision linked measurement can be summarized as:

Complete laser-vision calibration → Establish a target point element in the image area → Right-click and select "Automatic Laser Point Acquisition" → The machine moves and acquires automatically → A laser point element is generated

Afterwards, as needed:

Select 2 laser points → right-click to fit height

or:

Select 4 laser points → right-click to fit flatness

Usage Recommendations

Before using laser-vision linked measurement, make sure laser-vision offset calibration has been completed.

If the image point position deviates noticeably from the actual laser point acquisition position, check or redo the laser-vision calibration first, then continue using the automatic laser point acquisition function.
