- 1. Download libraries and dependencies
- 1.Initialization
echo 'SUBSYSTEM=="usb", ATTRS{idVendor}=="03e7", MODE="0666"' | sudo tee /etc/udev/rules.d/80-movidius.rules

2.depthai code library file package loading
git clone depthai: DepthAI Python API utilities, examples, and tutorials. #Download the code library to the main directory
As shown in the fourth data packet in the second row of the main directory in the figure
two. Compilation of code files
Example 1: Person detection
- Execute dependent code files
cd depthai #Enter the depthai directory, which is the directory where the dependent code files are located
python3 install_requirements.py #Execution
2. Execute code file
python3 depthai_demo.py -usbs usb2 #Force to use usb2 to transmit signals
Example 2: sdk point cloud
The sdk file requires more dependencies, and more dependencies need to be installed based on the previous installation of the depthai library.
- Dependencies required as long as you execute the sdk file
pip install -U depthai-sdk
2.Rerun visual point cloud, RerunSDK
pip install rerun-sdk
3. Enter the directory where the point cloud main program file is located
4. Right-click on the blank area and click Open in Terminal
5. Execute python3 pointcloud.py -usbs usb2, that’s it
Three: Analysis of Frequently Asked Questions
- Force usb2 communication
usb2 refers to the common four-contact port cable, such as a common charging cable, and the oak camera uses the usb3 interface by default, which is blue inside and has nine contact ports, as shown below. Generally, it is not available without special configuration. , if you use usb3 communication, you can remove the -usbs usb2 statement in the above command.
- import(error)problem
This problem is usually caused by two situations: there is a problem with the component version or there is a problem with the dependency version.
At this time, you need to update the version of the component or dependency according to the file needs. The component is similar to opencv-python, etc., and the dependency is like the update of depthai-sdk above. You need to use the statement in the terminal to update, such as pip install -U depthai -sdk, for other import issues, please refer to the troubleshooting section of the official documentation, the URL is at the end.
2.No module problem
In this case, the specific module has not been downloaded yet. Search the module name, find its download statement, and download it, or check the official documentation for similar fault reports. The methods to solve the problem are similar. You can check Take a look, maybe it will inspire you
3.Download problem of depthai library
For the oak camera library, when looking for open source code, it is usually downloaded when you download the depth package for the first time. There is no need to download it again, or rename it and then download an identical package. It is not necessary. Just do it next time, especially for those with URLs in official documents, ending with depthai, which are basically download addresses.

5. Remarks
- If you want to understand and correct the program more comprehensively and intuitively, you can choose to run it in pycharm instead of the terminal, which is more proactive and conducive to in-depth understanding of the code itself. Good morning and worry-free.
- This process inevitably requires scientific Internet access, such as accessing foreign code websites such as github, so you can do it early and save worry. You can also register an account yourself to share your IT experience
- For some details, just search on csdn. Don’t forget to bring ubuntu and its version number.
