Research Results

Researching on the topic two most important part is Jetracer & Line following algorithm. And lots of research has been done on those regards topic and following are some notable references and which will be implemented on during this thesis duration.

  • Jetracer is a AI based race car made by NVIDIA [1] for various project such as line following , the full configuration, connectivity and other material of the Jetracer can also be found in the official GitHub Jetracer page [2].
  • For configuration and Connecting to the network following the link Jetracer: Teach-In Tutorial can be helpful to set up the full process.
  • Describing the training process and experiments related to autonomous movement [3], this paper can give an clear outline for the full process. Also for object and design development [4] this paper give full insight with CNN and more technique.
  • Line following following process is can be difficult in various way, for vision based technique shown in this paper [5] its also very challenging to achieve the goal. And for CNN based technique which also can be done [6] has been discussed in the paper.
  • Lastly for motion control of the Jetracer which will be operate real time the system can be control & manage is achieve in this paper [7].
  • Additional resources : For steering angle prediction [8], MATLAB deep learning model [9], Video classification in MATLAB [10].


  • As a Result while doing the research both of the method(Computer vision and CNN) can be done extensively and mostly vision based technique will be used in this process.

Choose Environment

  • For this thesis, MATLAB will be used as a main Application. It has several advantages while doing the process such as real time system [11], extensive MATLAB libraries and toolboxes, compatibility with Jetson nano hardware [12] .
  • To create a simple morphologic box (Zwicky box) for the project can be outline as this:

borderless

Hard- and Software Setup

  • For the setup of Jetracer hardware it can be easily done following the manual [13], [[14]] and assemble it [15] .
  • For Software setup firstly the Jetracer which has the Jetracer AI Kit on SD card to set it up and all the config. which the full process can be found in [16].
  • MATLAB also is been installed on the local device to operate and manage the Jetracer. Then the addon package of nvidia-jetson is also installed for the hardware package. Various other package also been installed for this project such as Deep-learning, computer-vision, also gpu-computing.

Model development

  • Firstly connecting to the Jetracer and MATLAB according to the [17] MATLAB documentation, which help up to setup the full process.
  • For modeling the project it can be make as simple as possible to understand the steps to follow, in this paper [18],it shows some of the ideas and implementation can be done.
  • A outline of the line following algorithm diagram can be:





  • Firstly the camera configuration, Detecting the Jetracer camera then creating a video input object to set all the parameter like frame rate, resolution and others. Then the image acquisition can start its video labeling. [19]
  • For image acquisition after setting up camera, it start capturing image on fixed parameter which has been set. Image Processing for the line following starts as a capture the lane data from track, then convert it to grayscale image. Also applying edge detection(Canny), thresholding to locate the line and process the data. Then it continues the loop for the full process.






  • After getting all the data its time for analyze and make it setup for the Jetracer. While from the frame capture extracting the following line feature is main goal. Line positioning, direction of car, prediction of the path to follow next is also part of the process. All the analysis process the speed and steering control gets calculated to create a PID controller.
  • Controlling the Jetracer with PID controller has various complex steps to follow such as maintaining the speed, line, steering angle. Setting up the PID values to minimum at first then after identifying the error rate of the predicted line. Then tuning the parameters of the PID help to get the control results.
  • The structure of the model is divided in various part:
main.m: Contains the main loop and integrates other modules.
camera.m: Contains code for camera initialization.
processimage.m: Handles image processing.
detect_line.m: Implements the line detection algorithm.
PID_controller.m: Manages the PID control logic.
adjustSteering.m: Contains the code to adjust the Jetracer's steering.
