How to install Rasperry Pi with Daheng Imaging USB3 Machine Vision Camera
How to install Raspberry Pi C++ and Python SDK for industrial vision cameras?
In this article we will show video tutorials on how to install the Daheng Imaging Python and C++ SDK on a Raspberry Pi. All required drivers can be found in the download section of our website. Our GigE and USB3 industrial vision cameras do work with a raspberry pi. We have even tested multiple 5MP, 10MP, 18MP and 20 Megapixel industrial vision cameras on a single Raspberry Pi. Please note that a Raspberry Pi3 has only a USB2 an 100mbit ethernet port. Therefore the frame-rate will be lower. The Raspberry Pi4 has a USB3 and GigE port. On the Raspberry Pi 4, the USB3 port can achieve a maximum of 300mbit. This means that a 20MP industrial vision camera can run at max 15fps.
Raspberry Pi, 2 steps to Install Python Linux SDK of Daheng Imaging USB3 machine vision camera
In this chapter we will discuss how to install the Python Linux SDK for Daheng Imaging industrial USB3 Vision camera. This will be divided into two steps. Step one is the installation of the Linux SDK and step two is to run an example script.
Step 1, install Python Linux SDK on the Raspberry Pi
First we have to install the Python Linux SDK on the Raspberry Pi. The SDK can be downloaded from the download section on our website.
Step 2, how to run the example Python script GxSingleCamColor on Raspberry Pi
In this example python script we show how to acquire an image from the Daheng Imaging USB3 Vision camera and how to save the image on the Raspberry Pi.
Raspberry Pi, 3 steps to Install C++ Linux SDK of Daheng Imaging USB3 machine vision camera
Also, we have a C++ SDK for Linux that works on a Raspberry Pi in combination with Daheng Imaging industrial vision cameras. In the video tutorials below we show in 3 steps how to install the C++ SDK and run C++ example programs on the Raspberry Pi.
Step 1, install C++ Linux SDK on the Raspberry Pi
First step is to install the C++ Linux SDK on the Raspberry Pi. The Daheng Imaging SDK can be downloaded in the download section of our website.
Step 2, how to run C++ GxViewer example program on Raspberry Pi
The example C++ example script GxViewer shows how to acquire an image and display the image on a Raspberry Pi. It can also be used to change the parameters of the industrial vision camera that is connected to the Raspberry Pi.
Step 3, how to run C++ GxSingleCamColor example program on Raspberry Pi
The C++ example program GxSingleCamColor shows how to capture an image with Daheng Imaging industrial vision camera, using C++ code, on a Raspberry Pi.
Image Processing on a Raspberry Pi and OpenCV
The Raspberry Pi is getting more and more popular for image processing. The two main reasons for this are the low hardware price and the increased performance of the Raspberry Pi. Recently the new Raspberry Pi4 has been released, offering even an USB3 and GigE port and a more powerfull processor. For image processing mulitple libraries are available, but OpenCV is one of the most popular image processing libraries on a Raspberry Pi. You can now develop a very powerfull image processing application for a very affordable price, using our Daheng Imaging industrial vision camera in combination with OpenCV and a Raspberry Pi.
Do you need support with the Linux SDK on a Raspberry Pi?
If you have questions or encounter problems with the installation of Daheng Imaging C++ or Python SDK on a Raspberry Pi,or you are not able to acquire images from Daheng Imaging industrial vision camera, please contact firstname.lastname@example.org. Our technical support department will help you with connecting the Daheng Imaging industrial vision camera to a Raspberry Pi
Dear Hayder, thank you for your comments. In the download section you can find a python script for continues images grabbing and displaying

by adding numpy and opencv to the code and putting a loop in place, you can make a video feed using the opencv show. I've done it for myself and it works well. I expect your other customers would like that feature.

Hi. I have one of your daheng usb3 vision cameras. I'm using it with an nvidia jetson nano. Its working fine with your demo to get a single image. However I want to display a video stream. Since your demo uses PIL for displaying and saving a single image, its not suitable for streaming the video, processing it, capturing frame on a need basis etc... could you maybe provide a python OPENCV example?
