Using Depth of Field in your machine vision application

Depth of field is critical for acquiring a sharp image for the object/item that you are inspecting. Using the right depth of field, you can assure that the object/item that you are inspecting is in focus, while the background and foreground are out of focus. This way it is your vision software runs smoothly to recognize your object/item.Continue Reading

3 steps for using the Region Of Interest (ROI) function of a machine vision camera

This article demonstrates how to set up and use the Region of Interest function of our machine vision cameras, how to resize an image, and how to obtain the desired area. This is generally used for:

9 steps to calculate the frame rate of your machine vision camera using the frame rate calculator

To calculate the framerate of an industrial camera, a framerate calculator is available. This doc used to be available after installing the SDK. The frame rate calculator (an excel file) was located in the folder C:\Program Files\Daheng Imaging\GalaxySDK\Doc. Currently you can download the frame rate calculator from our download area.Continue Reading

I/O control: Learn to trigger machine vision lighting and to use a trigger sensor for giving hardware triggers to your machine vision camera

I/O control is crucial for effectively triggering machine vision cameras and lights. Industrial machine vision cameras are known for their reliability and robustness, so it's essential to have a dependable external triggering system.

When fast operation is required, the trigger sensor needs to respond quickly.Continue Reading

Limiting the frame rate to control the bandwidth usage of an industrial USB3 camera

Controlling the bandwidth usage of your industrial USB3 camera is essential to ensure stable and reliable data transmission. By limiting the framerate, you can effectively manage the amount of data transmitted over the USB3 interface. In this article, we will explore multiple options for bandwidth control and provide a step-by-step guide to calculating the required framerate for your industrial USB3 camera.

5 Steps to Trigger LED from Machine Vision Cameras using a Strobe Controller

Learn how to connect and trigger a LED light source with a machine vision camera using an industrial strobe controller. This is applicable to both USB3 and GigE machine vision cameras that have a trigger output. We have used the following hardware: 12V power supply, an industrial LED light, a MERCURY2 series Daheng Imaging machine vision camera, and a triggerable industrial strobe controller, the ACC-MV-LED-STROBECONTROLLER-V1.Continue Reading

Powering your industrial GigE camera by PoE (Power over Ethernet)

In this article, we will discuss four effective methods for powering a GigE camera: Utilizing a PoE Switch, employing a PoE Injector, utilizing a GigE Power adapter, or connecting to an external power source. When it comes to the power specifications of the MER2 series, the GigE camera can be powered through PoE, following the IEEE802.3af standard. Alternatively, it can be supplied with a voltage range of 12VDC-10% to 24VDC+10% via the GigE camera’s 8-pin Hirose connector.

3 steps for saving industrial camera parameters

If you have set the parameters of your industrial camera to meet the requirements of your application, it is possible to store these parameters settings in the camera for future use. By doing this, when you reboot or apply power to the industrial camera, it will automatically start with your saved parameters settings. Here are the three easy steps to follow:Continue Reading

Using (color) c-mount lens filters for your monochrome industrial camera

Learn how to create contrast, block external lighting, and improve object detection and measurement with (color) C-mount lens filters and a monochrome camera. Discover why monochrome cameras are preferred and how to apply lens filters without sacrificing image quality. The use of (color) C-mount lens filters is to be able to create contrast between colored parts of an object with a monochrome camera to easily detect and measure the specific part of the object. Additionally (color)C-mount lens filters are used to block external-environmental lighting. Why monochrome camera and not color?

Synchronize your machine vision cameras by hardware triggering

To achieve perfect synchronization between all industrial machine vision cameras, you will need the I/O port of the camera. The master camera will hardware trigger its slave cameras, ensuring flawless synchronization between them all. Follow our example to connect one master camera to three slave cameras, creating a perfectly synchronized setup of four machine vision cameras. Technical schematic of a synchronized machine vision camera setup:

How do I connect various industrial GigE cameras to one ethernet port of your pc?

Learn how to connect 4 industrial GigE cameras to a single network port with ease. To do so, you will need the following materials:

4x MER-630-16GC-P, 6.3MP industrial GigE cameras
5 Port PoE switch 1000mbit / 1Gbit
PC with windows 10 and a 1000mbit / 1Gbit network card

Before we begin, ensure that your connection speed is 1000mbit / 1Gbit and not 100mbit, as some PoE switches only offer the latter. This is a common mistake that many customers make, so it is crucial to double-check your connection speed before proceeding.
