Schedule
Show a simple table or figures that show your scheduled as planned before you started working on the project. Then in another table column, write down the actual schedule so that readers can see the planned vs. actual goals. The point of the schedule is for readers to assess how to pace themselves if they are doing a similar project.
| Week# | Date | Task | Status | Completion Date | Description |
|---|---|---|---|---|---|
| 1 | 3/21/2016 | Get individual Raspberry Pi 2 for prototyping & research OpenCV on microcontroller | Completed | 3/20/2016 | |
| 2 | 3/27/2016 | Continue Research and learning OpenCV. Familiarize ourselves with API. Know the terminologies. | Complete | 4/2/2016 | |
| 3 | 4/2/2016 | Complete various tutorials to get a better feel for OpenCV. Discuss various techniques to be used. | Complete | 4/2/2016 | |
| 4 | 4/4/2016 | Research on lane detection algorithms. IE. Hough Lines, Canny Edge Detection, etc. Start writing small elements of each algorithm. | Complete | 4/8/2016 | |
| 5 | 4/14/2016 | Run sample codes on a still, non-moving picture. | Complete | 4/8/2016 | |
| 6 | 4/20/2016 | Write our own algorithm, and test it. Camera input, Proper Hough Line generation. | Incomplete | Included blurring, edge detection, and Hough transform. This is the base for the lane detection.
Problem 1: A lot of noise being picked up by Hough transform. Status 1: Binarizing image seems to help decrease a lot of the noise. Gets rid of a lot of unnecessary objects Problem 2: Gaps in lanes do not complete Hough transform. Status 2: Currently working on Hough transform filters and Custom Region of Interest. Will possibly use birds-eye view. | |
| 7 | 4/22/2016 | Modify the code for our own project objective. Include a "lane collider" to see when we cross a lane. | Incomplete | ||
| 8 | 5/2/2016 | Implement the code with Raspberry Pi 2 | Incomplete | ||
| 9 | 5/8/2016 | Testing in Lab and attach feedback system (sound for warning) | Incomplete | ||
| 10 | 5/14/2016 | Testing on the road | Incomplete |

Design & Implementation
The design section can go over your hardware and software design. Organize this section using sub-sections that go over your design and implementation.
Hardware Design
Discuss your hardware design here. Show detailed schematics, and the interface here.
Hardware Interface
In this section, you can describe how your hardware communicates, such as which BUSes used. You can discuss your driver implementation here, such that the Software Design section is isolated to talk about high level workings rather than inner working of your project.
Software Design
Below shows the basic algorithm on how lane detection can be achieved. The problem is that this will still produce a lot of noise, and intermediary steps must be done for proper lane detection.
(IN PROGRESS)
Implementation
This section includes implementation, but again, not the details, just the high level. For example, you can list the steps it takes to communicate over a sensor, or the steps needed to write a page of memory onto SPI Flash. You can include sub-sections for each of your component implementation.
Color Spaces
IPM (Inverse Perspective Mapping)
Gaussian Blur
Canny Edge
Hough Line
Percentage offset
Switching Lanes
Testing & Technical Challenges
Describe the challenges of your project. What advise would you give yourself or someone else if your project can be started from scratch again? Make a smooth transition to testing section and described what it took to test your project.
Include sub-sections that list out a problem and solution, such as:
Issue 1: Noise
There are Large amounts of noise when generating Hough lines. This is because there are lines in each picture. Standard Hough lines do not work because you cannot set the minimum and maximum lengths of lines. Probabilistic Hough Lines are the best bet for this task. Even with Probabilistic Hough Lines, there is still quite a bit of noise.
Solution:
We did not use Probabalistic Hough Line. We used the standard one. Instead of using the Gaussian Blur, converting the image to HSV and then binarizing(threshold) it was sufficient. Adjusting HSV and threshold allows us to just the lanes. This is not perfect because there will still be some noise. To filter out more of the noise, we filtered out unnecessary horizontal angles because lanes from the driver point of view, is not horizontal, but slanted vertically. We filtered between the angles of 15 and 60 degrees for the left lane, and 115 and 145 degrees for the right lane.
