Machine vision detection solutions for your projects

Are you looking for a solution based on image processing to control your products? Are you wondering if image analysis would be a suitable solution for your problem? Are you looking for a company to design and build an automated machine, potentially using cameras and vision systems?

Le Sur-Mesure Industriel regularly installs vision-based equipment and systems in its machines to carry out various automated applications. We deal with many inspection topics, based on the most relevant technologies depending on the objectives and performance required of the system: sensor, stand-alone camera, PC-based camera, linear camera.

Image reading for a customized inspection

As part of continuous improvement, equipment modernization, and function automation, our team is also required to address issues of industrial vision, integrated or added to existing equipment. We can also ensure the replacement or upgrade of existing vision equipment or applications on your equipment or production line.

Do you need to test your products to verify the relevance of vision solutions according to your criteria and your reading or detection objectives? Are you looking to automate a check, a foolproofing, a measurement using machine vision technologies by camera?

A project with us: feasibility, a crucial step

An inspection or detection project using a camera, lens, lighting most often starts with a feasibility and testing stage. This extremely important phase obviously depends on the complexity of the subject. It allows the choice of the most suitable equipment and the definition of the best layout for lighting and the camera taking into account your products, the characteristics and areas to be inspected, the integration constraints, the available processing time. Our experience and testing combine to finely configure the solution.

Our team from A to Z for the integration of vision solutions

Our multidisciplinary team is at your service to handle your subjects involving machine vision, cameras, lighting from A to Z. We are able to design mechanical assemblies, supports, adjustments, etc. We even sometimes develop specially suitable lighting when commercially available lighting is not suitable. We are therefore free to choose, arrange and orient the LEDs according to the needs of the application. The fixings and cooling of the system are also taken into account during these special developments.

We also handle the electrical integration of components into equipment, then the creation of programs allowing the desired image analyses. Application programming also deals with communication with other interfaced systems: PLC, HMI, user, industrial robotics, PC, database, etc.

Finally, we ensure assembly and development in order to optimize the settings, define all the decision criteria and thresholds, in order to make the analysis result as reliable as possible, while respecting the required quality criteria. Finally, we ensure on-site installation, and training of people, then after-sales service for the maintenance and development of your equipment over the years. Some projects are also handled in direct partnership with the developers at our customers but also in co-contracting with the neighboring company Process Engineering according to the specificities of the application.

The benefits of image processing for automated machines or lines

Among the senses of the human body, sight is very efficient for placing an object, analyzing the characteristics of a product, checking the presence of a component, a shape, a color, the presence of an anomaly, etc.

On the other hand, the industrial context will quickly generate a lot of fatigue, risk of error, monotony if these missions are exclusively entrusted to humans. Machine vision systems aim to perform these operations of processing the information contained in the images by always pushing the limits in terms of rate, reliability, precision, repeatability. This becomes very practical and useful for detecting an anomaly, analyzing a production, improving quality, validating the conformity of products during production for example.

What is machine vision used for?

Machine vision uses images to automate the processing and analysis of information to meet a given application. From an image taken by the camera, we create a custom program using different filters and tools to analyze the image and exploit its content.

The application may consist of an analysis of the presence, integrity, position, orientation, shape of a component. Depending on your activity, your products, your quality objectives, it may be useful to measure a characteristic, count, recognize, correct, etc. Many applications also require text reading, code reading (1D, 2D, QR code). The criteria can be numerous and the applications in the industry very varied: production, quality, assembly, robotics, etc.
Also see other examples of measurement and control applications.

Frequently asked questions about machine vision systems

What is a vision system?

A vision system is made up of different hardware: camera, lens, lighting. All of these components must be carefully chosen in order to meet the expected goal of the vision function to be developed.

How much does a machine vision system cost?

It is necessary to carefully analyze the need, the context and the objective sought for each application. This allows us to determine the appropriate hardware and development to achieve it. Depending on the complexity and the hardware used, prices can vary greatly. Let us know your need to receive a quote.

What is the role of the camera for image processing inspection applications?

The camera allows the acquisition of the image. Many important criteria must be chosen carefully depending on the applications: installation distance, field of vision, resolution, sensor, etc. The communication mode with the different interfaces will also be an important parameter. Some cameras are interfaced via USB, others via Ethernet. There are large families of products: Vision sensor / Standalone camera / camera for PC base, Linear cameras.

What is the purpose of the lens mounted on the camera and how to choose the right one for your control?

The lens is mounted on the camera and allows, depending on its characteristics (focal length, aperture, image resolution, mount), to select the field of vision according to the installation distance and the size of the area we are trying to observe. The lens integrates the aperture and focus settings. It is also possible and sometimes wise to use a filter to select certain wavelengths or colors to observe.

How to choose the right lighting for your vision detection application?

Too often neglected during feasibility studies or vision system studies, lighting is an essential component of an industrial vision system. Its definition, choice and implementation are essential for the success of a function developed in industrial vision. There are different ways to illuminate an area to be observed and each project has its own specificities. For a vision application, we take care to properly define the lighting in order to highlight the characteristic to be observed. Lighting makes it possible to be the predominant light source, making variations in ambient light insignificant, in order to make analyses more reliable.
