Install driver for Daheng Camera

Windows

Have a look here: https://www.get-cameras.com/requestdownload and install the drivers. / SDK

Linux

ARM

You can use the camera on the Raspberry Pi or Jetson Nano. For this you can do the following steps:

cd ~
cd Downloads
wget https://dahengimaging.com/downloads/Galaxy_Linux-armhf_Gige-U3_32bits-64bits_1.5.2303.9202.zip
cd Galaxy_Linux-armhf_Gige-U3_32bits-64bits_1.5.2303.9202
chmod +x Galaxy_camera.run
sudo ./Galaxy_camera.run
# go through questionaire
sudo reboot

Install Python bindings

cd ~/Downlodas
wget https://dahengimaging.com/downloads/Galaxy_Linux_Python_2.0.2106.9041.tar.gz
tar -xvf Galaxy_Linux_Python_2.0.2106.9041.tar.gz
cd ~/Downlodas/Galaxy_Linux_Python_2.0.2106.9041/api
# conda activate ****ENV
pip install -e .
cd ~/Downlodas/Galaxy_Linux_Python_2.0.2106.9041/api
python ~/Downloads/Galaxy_Linux_Python_2.0.2106.9041/sample/GxSingleCamMono  GxSingleCamMono.py

The result will be:
