Mech-MSR 2.1.1 Release Notes

New Features

Supports the Calibration of Laser Profilers in Angled Layout

Now you can use the software to calibrate 2 to 4 laser profilers arranged in an Angled layout. If the number of laser profilers exceeds the limit, you can perform single-group calibration multiple times and then combine calibrated groups.

See Multiple Laser Profiler Calibration for details.

Added Point Cloud–Related Steps

The following Steps related to point clouds are added to process the data acquired by laser profilers in an Angled layout. You can use the 3D Laser Profiler Step to connect to multiple laser profilers arranged in an Angled layout and thus obtain point cloud data.

Convert Point Cloud to Surface Data

This Step is used to convert a 3D point cloud to two sets of surface data, top surface and bottom surface, by orthographic projection. The point cloud can be transformed beforehand for better projection results.
Fit Plane to Point Cloud

This Step is used to fit a plane to a 3D point cloud.
Generate Bounding Box for Point Cloud

This Step is used to generate the minimum volume bounding box for a 3D point cloud.
Transform Point Cloud

This Step forms a new reference frame by the input geometric features such as a plane, a line, or a point and transforms a 3D point cloud into this reference frame. It also supports transformations within the point cloud’s current reference frame.

Supports Global Variables

Global variables can be accessed and used by all projects under the same solution. They enable data sharing across different projects for consistent data management and transfer. You can use the Global Variable Step to save and retrieve data and view all saved global variables via Global Variable Viewer.

Added Mitsubishi MELSEC Client Communication Mode

The 3D Measurement System can now communicate with Mitsubishi PLCs through the Mitsubishi MELSEC communication protocol (i.e., the MC protocol). See Configure Mitsubishi MELSEC Communication to learn how to configure in Mech-MSR.

Improvements

Enhanced Deep Learning Feature

When the following types of model packages are used in the Deep Learning Model Package Inference Step, more features are supported:

Text Detection

Sorts detected text regions by the position of their center points, either from Left to right or Top to bottom.
Text Recognition

Joins multiple texts recognized from an image into one.
Instance Segmentation, Classification, and Object Detection

Supports selecting the display mode of classes, by name or by index. In versions earlier than Mech-MSR 2.1.1, only indexes can be displayed for classes.

Model packages exported from Mech-DLK 2.6.2 or later versions may not work in Mech-MSR:

Multi-class Defect Segmentation model packages can only be used in Mech-MSR 2.1.1 or later versions, not in 2.1.0 and earlier versions.
Currently, Mech-MSR does not support model packages trained and exported on NVIDIA GeForce RTX 50 Series GPUs.

For more information about the compatibility of deploying deep learning model packages, see Deep Learning Compatibility.

Improved Production Interface

The improvements to the production interface are as follows:

The display window now can show the circle feature.Previous versions only supported displaying circle centers.
In the display window, another image can now be overlaid on the existing image in either Contour or Mask mode.

See Configure Display Windows for details.

Adjusted Names of Port Data Types and Dimensions of Basic Data Types

The names of port data types and the data dimensions of the basic data types have been adjusted. This change only affects the use of the Calc Results by Python Step. See the Parameter Description of this Step for details.

Resolved Issues

The following issues have been resolved in Mech-MSR 2.1.1:

When multiple projects in the same solution were connected to the same laser profiler, and the signals received by DI terminals were configured to trigger the projects, the software would abnormally run the corresponding configured project multiple times each time it received a signal.
When a “Gap Filling” filter was used in the Process Surface by Filter Step, the Y-direction filter did not take effect when selected.
