Autonomous Driving Object Detection on the Raspberry Pi 4!

In this tutorial, the instructor demonstrates the steps required to configure the Raspberry Pi 4 for object detection with an autonomous driving trained neural network. This includes cloning the repository, setting up a virtual environment, installing dependencies such as GPIO, OpenCV, and TensorFlow, and configuring the Raspberry Pi camera module. Next, the instructor demonstrates connecting an LED and push button to the Pi and running a Python script to capture images with object detection. Finally, the user can make adjustments to the batch rc file to run the script on boot and record footage with the images saved to the output path.

  • 00:00:00 In this section, the video instructor walks through the software configuration steps to perform object detection with an autonomous driving trained neural network on Raspberry Pi 4. The instructor starts by ensuring the Raspberry Pi is up to date, cloning the repository provided in the video description, and installing a virtual environment to keep dependencies for this project separate from other projects on the system. The instructor then activates the virtual environment before installing dependencies such as a gpio python package, OpenCV, and TensorFlow, which are all things needed for the project, by running a bash script. Finally, the instructor shows how to configure the Raspberry Pi camera module by entering the configuration settings in the terminal and connecting it to the Raspberry Pi 4.

Similarly, a push button is added to the breadboard to allow starting and stopping the processing of images. The presenter then shows the software side of the setup by running a Python script with arguments for the monitor neural network and output path, which saves the processed images to a specified location.

  • 00:10:00 In this section, we see the output path and where the images captured by the Raspberry Pi with object detection are saved. The user goes on to make adjustments to the batch rc file so that the python script runs on boot, without the need for a keyboard or mouse. The final step is to put the Raspberry Pi in the car, plug it into an AC outlet, and start recording footage with the processed images saved to the output path specified. The user suggests that the captured images can be turned into a gif or a video.

In this video tutorial titled "Object Detection OpenCV Python | Easy and Fast (2020)," the presenter demonstrates how to create an object detector using the OpenCV library in Python. The video focuses on creating a detector with a balance between accuracy and speed that can detect multiple commonly found objects in real-time. The MobileNet SSD model is used for object detection due to its speed and accuracy, and the coco dataset is used to detect classes like person, bicycle, and car. The video shows how to loop through various variables using the zip function to create a rectangle around the detected object and how to modify the code to run object detection on a webcam feed. The presenter also explains how to adjust the threshold value and add confidence values to detected objects to understand the probability of each object.

  • 00:00:00 In this section of the video, the creator discusses how to create an object detector with a good balance between accuracy and speed. The detector can run in real-time while detecting multiple common objects and does not require any third-party libraries to run other than OpenCV. The video goes through the codes of creating an object detector and explains in detail the usage of the MobileNet SSD, which has a good balance between accuracy and speed, and can run on a CPU almost in real-time, making it an excellent choice for detecting common objects. Finally, opencv-python is the only library needed to run the detector, and the coco dataset is used to detect classes such as person, bicycle, and car.

  • 00:05:00 In this section of the video tutorial, the presenter demonstrates how to display an image using the OpenCV library in Python. They import names of objects from the coco dataset using the with open function and read it in as an array. They then import configuration files and weights and use the OpenCV function to create the model. Unlike in the YOLO video tutorial, where techniques had to be applied to extract the bounding box, the function does all the processing for us, and all we need to do is pass the image, and it will display the bounding box and ID names.

  • 00:10:00 In this section, the video tutorial explains how to perform object detection using OpenCV and Python. After configuring the detection model, the code sends the input image to the model and returns the class ids, confidence levels, and bounding boxes.

The code can be utilized for various applications such as self-driving cars or robotic devices. The tutorial also touches on the importance of class ids and the significance of subtracting one from their values when referring to the class names.

  • 00:15:00 In this section, the instructor explains how to loop through three different variables or information using the zip function. They use zip to flatten the confidence and bounding box variables and then use a for loop to create a rectangle around the detected object. They also write the name of the detected object using the putText function and use the class names variable to subtract one from the class id to get the appropriate name. The instructor adds other parameters to make the label more visible and even changes the text to be all in capital letters. Finally, they successfully detect a person in the image.

  • 00:20:00 In this section, the tutorial demonstrates how to modify the code to run object detection on a webcam feed instead of static images. The code uses "cv2.videoCapture" to initialize the webcam and set the image size parameters. The while loop is used to constantly capture and display the webcam feed, and a condition is added to check if any object has been detected before displaying it. The system accurately detects objects such as a keyboard, monitor, cell phone, and mouse in real-time using the webcam feed.

  • 00:25:00 In this section, the author explains that the object detection algorithm can detect objects with good speed and accuracy, even though it might not be the best accuracy.
