I was studying your traffic detection app on the Ezblock for Pi-Car X and wondered how it works. I looked on the OS and found no image files it could match too. So how does it work? Larry ---

Combine traffic sign detection with line patrol functionality. Let PiCar-X track this straight line and when you place a stop sign in front of it, it stops. When you place a forward sign in front of it, it will continue to move forward. ---

How do I add different types of signs? How can a new variable know what the image looks like? ---

The traffic standard model is a tensorflow modality trained by image classification, the ezblcok program references the model here: [https://github.com/ezblockcode/ezb-pi/blob/EzBlock3.1/workspace/vilib.py#L71](https://github.com/ezblockcode/ezb-pi/blob/EzBlock3.1/workspace/vilib.py#L71), and for the lexicon [https://github.com/ezblockcode/ezb-pi/blob/EzBlock3.1/workspace/vilib.py#L64C49-L64C49](https://github.com/ezblockcode/ezb-pi/blob/EzBlock3.1/workspace/vilib.py#L64C49-L64C49) If you want to train your own model, you can refer to the following tutorial on image categorization: [Image Classification — SunFounder Pan-tilt HAT Kit documentation](https://docs.sunfounder.com/projects/pantilt-v3/en/latest/python/python_image_classification.html) via Google’s Teachable Machine to train tf models online In the meantime you can refer to the vilib library for image classification and traffic sign recognition programs: [https://github.com/sunfounder/vilib/blob/dev/vilib/image\_classification.py](https://github.com/sunfounder/vilib/blob/dev/vilib/image_classification.py), the [https://github.com/sunfounder/vilib/blob/dev/vilib/traffic\_sign\_detection.py](https://github.com/sunfounder/vilib/blob/dev/vilib/traffic_sign_detection.py) ---

I followed train your own model, you can refer to the following tutorial on image categorization: [Image Classification — SunFounder Pan-tilt HAT Kit documentation](https://docs.sunfounder.com/projects/pantilt-v3/en/latest/python/python_image_classification.html) via Google’s Teachable Machine to train tf models online. It took the photo. I then created the I **Install Samba** and set the smbpasswd -a pi I could not map the network drive. Please advise. Larry ---

Not quite sure what you mean, is it a case of not being able to log in to your Raspberry Pi, if it’s a remote login, make sure the Raspberry Pi is powered on and on the same LAN as your operating device.
