How to set a Region of Interest (R.O.I.) inside an industrial camera in 3 steps

  Technical Support     29-07-2020     Reacties (0)

How to set a Region of Interest (R.O.I.) inside an industrial camera in 3 steps This guide will explain how to set and use the Region of interest function of the industrial camera, how to resize an image and how to capture only a defined area. This is commonly used to: -    reduce the amount of collected data -    reduce the required bandwidth -    increase the framerate of an industrial camera -    isolate the view on a certain area In this article we will set a Region of Interest and offset it from the top left corner to the centre of our image. Using these 3 steps you can define the size and position of the industrial cameras Region of Interest. STEP 1: CHECK THE IMAGE SIZE AND DEFINE REGION OF INTEREST Check the maximum image size (resolution) of your industrial camera and define your desired Region of Interest. For this example, we...

How to use Power over Ethernet (PoE) with a GigE camera?

  Technical Support     21-07-2020     Reacties (0)

How to use Power over Ethernet (PoE) with a GigE camera? This article will explain 4 different ways to power a GigE camera. It contains powering the industrial camera via a PoE Switch, PoE Injector, GigE Power adapter and via an external power source. How to use Power over Ethernet with a PoE switch and a GigE PoE industrial Camera? A Power over Ethernet switch transmits power and data via a CAT6 network cable. This means that if your machine vision application has a GigE industrial camera with PoE, you do not need an extra external power supply. The maximum length of the CAT6 network cable is 100 meters. This is not due to power limitation, but data transmission limitations. The example below shows how to transmit data and power between a GigE industrial camera with PoE and a computer using a PoE switch. How to use Power over Ethernet without a PoE switch?

Color Lens Filters

  Technical support     23-06-2020     Reacties (0)

Color Lens Filters How to use (color) C-mount lens filters? 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? Because monochrome cameras  are up to 3 times more light sensitive and produce sharper images. (Color)C-mount lens filters can be applied to camera lenses without significant loss of light or image quality. Color lens filter principle Using a Color lens filter to add contrast works on subtraction idea. For this example we take a red bottle cap with red lens filter. The red Lens filters does not brighten up the cap. Instead, the complementary colors and the colors...

  Technical support     18-06-2020     Reacties (0)

Hardware trigger cameras, master and slave(s) How to synchronize industrial machine vision cameras? To synchronize industrial machine vision cameras the I/O port of the industrial camera is required. A master camera will hardware trigger it’s slave cameras to assure perfect synchronization between all cameras. In this example we explain how to connect 1 master camera to 3 slave cameras. As a result the setup will have 4 industrial cameras perfect synchronized. Technical schematic of a synchronized camera setup: The schematic below shows how to trigger 3 slave cameras from 1 master camera. An external power supply is always required. The external power supply voltage range should be between 5 and 24V. In our example we will use a 12V external power supply for the synchronized camera setup. The power Line 1 output can withstand 25 mA max. A Line 0 input(s) needs 7mA...

Product life cycle of industrial cameras

  Technical support     07-05-2020     Reacties (0)

Product life cycle of industrial cameras All our industrial cameras have a minimum life cycle of 7 years after market introduction. The graph below shows the typical product life cycle stages of an industrial camera. Market introduction of an industrial camera When a camera is released it has the latest generation sensor. In almost all cases the latest generation sensor is more light senstive and has less noise than previous generation sensors. Therefore a better image quality can be achieved. Check for newer alternatives After 3-7 years, sensor manufacturers will release a new version of the sensor or a sensor from a different brand might have better imaging performance. Therefore during this period it's important to check if there are other camera types available that have a newer image sensor. EOL Notification Unfortunately cameras do go End of Life (EOL)....

Connecting multiple GigE cameras to one ethernet port How do I connect multiple GigE industrial cameras to a single network port? We will explain how to connect 4 industrial GigE cameras. Therefore we have used the following material: 4x MER-630-16GC-P, 6.3MP industrial GigE camera 5 Port PoE switch 1000mbit / 1Gbit PC with windows 10 and a 1000mbit / 1Gbit networkcard Please double check that your connection is 1000mbit / 1Gbit and not 100mbit. Some PoE switches are only 100mbit and we see more often that customer think they have 1Gbit connection but in reality they have a 100mbit connection. This article explains how you can check if you have a 1 Gbit connection. You can only check this when the industrial GigE camera is connected.

Industrial polarization camera whitepaper Industrial Polarized Camera Daheng Imaging is dipping their toes in the industrial polarized camera segment by implementing the Sony-IMX250MZR monochrome image-sensor . The Industrial polarization camera systems are able to capture information which a normal line or area industrial camera is not able to obtain. A polarization camera conducts a two-dimensional analysis. It measures both the degree and direction of the polarization of the light. As a result the final image has almost none reflections from external lightsources. A polarized camera is ideal for applications like the inspection of glossy products and transparent products.   Standard machine vision camera versus polarized camera The following examples show on the left hand side an image captured with a standard machine vision camera and on the right...

How the European Vision camera market got disrupted

  Vision Camera Specialist     06-10-2018     Reacties (0)

How the European Vision camera market got disrupted Many years the European camera manufacturers dominated the machine vision camera market worldwide. Time is changing and Chinese camera manufacturers are entering the European market. Only a few Chinese camera manufacturers, like Daheng Imaging , can offer high quality products for a low price. European vision camera manufacturers can’t compete on price because the Chinese camera manufacturer have the following competitive advantages: No overhead features. Most Chinese vision cameras have standard features like exposure, gain, white balance control, etc, but no advanced features like pixel binning and skipping. By reducing the amount of advanced features, less development time and less expensive FPGA's (Hardware) is needed. This results in lower cost price per camera Scale of Economy. China is the largest...
