Dashboard Display Module

The Racecar DashBoard Display Module is a unit to replace the car mirrors and displays the car performance to the driver. This module interfaces between a screen and multiple cameras using a raspberry pi. This is for a semseter long "capstone" project for Swinburne University

Requirements

• Speedometer
• Clock
• Side and Back mirror options
• Safety Information

Requirements

The project needs the following software installed...

1. update Rpi system

sudo apt update 2.python & pip sudo apt install python
sudo apt install python-pip

3. numpy

pip install numpy

4. pygame

pip install python-pygame

5. openCV

pip install python-opencv

The project needs the following hardware avaliable...

1. RPi4 (unsure of previous versions are compatible)
2. 3 USB cameras connected
3. Display output (the target device was 1280 x 400)

Versions

1.07 Design Updates

Final result on RPi4

1.06 Design Updates

Daniel Revamped the design to look slick.

1.05 Image Detection

Due to the OpenCV library, we were able to integrate machine vision using a trained model (XML).

1.04 OpenCV Camera

Camera Support! Each camera runs on their own thread and each image is read from alternating buffers for thread safety. This works out perfectly as we need support for 3 cameras and the RPi4 has 4 cores... (3 camera threads and 1 main thread).

1.03 Pygame Demo

After poor performance on the Raspberry Pi, Willis changed the GUI from Tkinter to Pygame. This tripled the performance.

Desktop	Tkinter	Pygame
Time (ms)	3.536	1.053
Freq (Hz)	282.8	949.7

RPi4	Tkinter	Pygame
Time (ms)	24.44	40.92
Freq (Hz)	4.711	212.6

• From 40 fps to 200 fps (on the target device) was a major and neccessary improvement.

1.02 Tkinter in Realtime

Willis improved Daniel's demo by making the mainloop dynamic instead of controlled by Tkinter. Also added gif and png shapes.

1.01 Tkinter Demo

Daniel created and implemented a working prototype that had a working speedometer, rpm, range and more.
