Working with Windows PC

Test Software

Currently, a camera app is generally pre-installed on most Windows 10 systems. You can simply open this built-in Windows camera app to perform testing.
If you are using Windows 7 or cannot find the camera app in the system, you can download and install the AMCAP test software provided by us from Resources->Software.

Test Steps

Window camera software
  • Search for "Camera" to open the software
  • Click the gear icon in the upper left corner to open the settings interface, where you can set the resolution for taking pictures or videos

  • Click the video or capture icon on the right to switch between recording and shooting
AMCap software
  • Download and install AMCap software
  • You can click on the Option option and select Video Capture Pin... or Still Capture Pin... to set the parameters of the image and video

Working with Raspberry Pi

Preview with Plugins

  • Open the Raspberry Pi terminal, enter the command to install the luvcview software
    • sudo apt-get install luvcview -y
  • After installation, enter the command on the terminal to open the software for USB camera testing
sudo luvcview -s 1920x1080

Preview with Scripts

  • Install opencv
sudo apt-get install python3-opencv
