Gocator G2 Universal Robots Support - LMI Gocator

In addition to the currently supported Gocator® 3D snapshot sensors, engineers can now easily integrate Gocator® 3D laser line profile sensors into their UR applications.

This is achieved through the Gocator® URCap plugin, which performs precision hand-eye calibration between sensor and robot flange.

Easy UR integration allows engineers to implement a complete vision-guided robotic solution – with minimal cost and development time – in applications that benefit from 3D laser line scanning such as measurement and inspection of elongated targets (e.g., cables, pipes, conduits), or applications that require larger fields of view not covered by G3 sensors (e.g., large bin picking).

Image Band Pass Filter - Deediim Sensors

Surface defects can be defined by the change in surface property. For example, surface defects such as dents can be seen as a change in surface inclination, scratch as a change in surface roughness while stain can be seen as a change in surface reflective.

But until now, conventional lighting products have been used to detect surface defects only by utilizing brightness values, which has caused poor and unstable results. Furthermore, if a surface had changes in reflective and geometry, this usually resulted in crucial information loss.

To overcome these obstacles, we have developed a lighting system that directly measures 3 surface properties (inclination, roughness and reflective) by combining multiple images and outputting it as processed images.

These high-quality images can be used to detect complex defects regardless of sample & lighting conditions. In addition, classifying defects can also be achieved by a combination of the processed images. These high-quality images can especially be a good fit when combined with deep learning (AI) solutions.

All-in-one Illumination Solution - Deediim Sensors

Engineers usually depend on their knowledge and experience when choosing the correct lighting but if unsuccessful, this can lead to an extensive and time-consuming process. This is because there are hundreds of different lightings that exist in the market and most applications require a different lighting depending on its surface property and geometry.

This is the main reason why many engineers still spend a lot of time selecting the correct lighting for different types of applications (e.g. lighting type, size, color, gradation, etc.).

The free-illumination mode is an all-in-one solution that can replicate most lighting products out in the market, just by using one lighting system. This has been made possible by using a proprietary lighting system where hundreds of LEDs are independently controllable.

Every single LED’s brightness and color can be controlled, meaning you can now draw & replicate all sorts of lighting conditions according to your needs. This will benefit engineers to a great extent when selecting correct lightings and can also simplify machine vision systems that use multiple lightings for inspection.

Anomaly Detection - MVTec Halcon

HALCON's deep-learning-based anomaly detection allows you to easily detect whether images contain deviations from known training data. To train this network, only a relatively low number of "good" images is required. Consequently, there is also no need to label any data.

Combined with its simple and flexible workflow, anomaly detection significantly increases the possibilities to solve your applications.

Introducing Surface Masking - LMI Gocator

In certain inspection applications, the engineer needs to isolate a specific feature in order to take measurements of a part. We recently introduced the Surface Mask tool in Gocator® to solve this challenge.

To illustrate how the tool works, we’ll use a connector with 4 pins as our scan target.

The goal in this application is to measure the surface flatness of the face of the flange, which is the innermost ring of the connector.

Using the Surface Mask Tool

Measuring the surface flatness of the face of the flange is easily solved using a Gocator® 3D laser line profiler or snapshot sensor and two built-in tools. First, the Gocator® sensor scans and generates a 3D surface of the connector.

In the browser-based Gocator interface, drag and drop the Surface Mask tool to isolate the region representing the face of the flange (represented by the orange ring of data). Then apply a circular mask (to match the shape of the flange), configuring it to extract a partial ring of data from the original scan.

The Surface Mask tool creates a new surface by extracting specific data from the desired region, and excluding data from surrounding regions.

The image below shows the extracted data after the Surface Mask tool has been applied. This extracted data can then be further processed by other tools, or measurements can be applied to the surface data itself.

Making a Surface Flatness Measurement

Next, apply the Surface Flatness tool to make a measurement of the flange. Set the input of the Surface Flatness tool to the output of the Surface Mask tool, then define the region of interest to include the isolated flange data.

This combination of surface masking with measurement makes it easy to solve the connector flange inspection task.

Choosing from Circular, Elliptical, Polygonal, and Rectangular Regions

Circle is not the only region offered in the Surface Mask tool. There are four different region types available, depending on the shape of your scan target.

These four regions are:

(1) Circle - As seen in our connector example

(2) Ellipse

(3) Polygon – For irregular and complex shapes

(4) And Rectangle

Benefits of Surface Masking

The great thing about the Surface Mask tool is that it allows you to centralize region-based masking in a single location, and export specific regions to multiple downstream measurement tools––saving you valuable time and setup effort.

The tool also allows you to define up to 16 masking regions simultaneously, and extract surface data based on those masks. Each masking region’s size, position, and shape (including circular, elliptical, polygonal, and rectangular) can be individually configured. Regions can be overlapped to create even more possibilities for custom mask regions
