Real-time object detection on a phone using TensorFlow Lite is a powerful tool that can be used for a variety of applications, such as augmented reality, image recognition, and even security monitoring. In this tutorial, we will cover the basics of setting up TensorFlow Lite on your phone and running an object detection model in real-time.
Step 1: Install TensorFlow Lite on your phone
The first step is to install TensorFlow Lite on your phone. TensorFlow Lite is a lightweight version of the popular TensorFlow library that is optimized for running machine learning models on mobile and IoT devices. To install TensorFlow Lite, you can follow these steps:
1. Go to the Google Play Store or Apple App Store on your phone
2. Search for “TensorFlow Lite” and download the app
3. Open the app and follow the on-screen instructions to install TensorFlow Lite on your phone
Step 2: Download a pre-trained object detection model
Next, you will need to download a pre-trained object detection model to run on your phone. TensorFlow Lite provides a wide variety of pre-trained models that you can download and use for your applications. One popular object detection model is the MobileNet SSD model, which is optimized for running on mobile devices.
To download the MobileNet SSD model, you can follow these steps:
1. Go to the TensorFlow Lite Model Zoo at https://www.tensorflow.org/lite/models
2. Search for the MobileNet SSD model and download the model file (usually a .tflite file)
3. Save the model file to your phone’s internal storage or SD card
Step 3: Load the model into TensorFlow Lite
Once you have downloaded the pre-trained object detection model, you will need to load the model into TensorFlow Lite on your phone. To do this, you can follow these steps:
1. Open the TensorFlow Lite app on your phone
2. Tap on the “Load model” button
3. Browse to the location where you saved the model file and select the file
4. Tap on the “Load” button to load the model into TensorFlow Lite
Step 4: Run the object detection model in real-time
Now that you have loaded the object detection model into TensorFlow Lite on your phone, you can run the model in real-time to detect objects in the camera feed. To do this, you can follow these steps:
1. Tap on the “Start camera” button in the TensorFlow Lite app
2. Point your phone’s camera at an object and wait for the model to detect it
3. The object detection model will highlight the detected objects in real-time on the camera feed
4. You can tap on the detected objects to see more information about them, such as their class label and confidence score
Step 5: Customize the object detection model
If you want to customize the object detection model or train your own model, you can do so using TensorFlow Lite. TensorFlow Lite provides tools and libraries for converting TensorFlow models to the TensorFlow Lite format, as well as for training custom models on your own data.
To customize the object detection model, you can follow these steps:
1. Build and train a custom object detection model using TensorFlow
2. Convert the TensorFlow model to the TensorFlow Lite format using the TensorFlow Lite Converter
3. Load the custom model into TensorFlow Lite on your phone and run it in real-time
By following these steps, you can perform real-time object detection on your phone using TensorFlow Lite. This powerful tool can be used for a variety of applications, such as augmented reality, image recognition, and security monitoring. Experiment with different object detection models and customizations to see what works best for your specific use case.
我也做到了这一步,但是无法运用到实际中去
You know the algorithm from opencv for distance measurement
Can we get a tutorial on how you implemented this.
It would be helpful if you made videos on mobilenet fine-tuning for image detection. Because when I tried to fine-tune the model I could classify them but couldn't detect them.
Besides, when I tried to export the yolov8 model to tflite, the dimension of the model output changed which was not working while inferencing the tflite model, but when I manually trained the model with tf and converted it to tflite, it worked.
I'm new at computer vision. That performance looked worse than yoloV8 to me.
