| # **Final Year Project** | ||
|
|
||
|  | ||
|
|
||
| # Stage Criteria | ||
|
|
||
| This is the criteria I would like to meet, to feel as though I have created a successful project. | ||
|
|
||
| | Stage | Name | Description | | ||
| | ----- | --------------------------- | ------------------------------------------------ | | ||
| | 1 | Smart shades | Make a set of smart sun classes | | ||
| | 2 | Auto smart shades | Add LDR to control the opacity | | ||
| | 3 | Auto smart point shades | Add camera to make dark point over bright points | | ||
| | 4 | Controllable smart shades | Add options to swap between modes | | ||
| | 5 | Driving/safety improvements | Auto react headlights etc. | | ||

| ## Plan | ||
|
|
||
| The product's above, along with Paul's lectures last year inspired my idea. | ||
|
|
||
| The plan is to use two LCD's with the backlight removed, to create dimmable panels in front of the users eyes. Then eventually I will add a camera to make point control which will block bright spots such as projectors and the sun, and dim them to reduce squinting. | ||
|
|
||
| # Final mock-up | ||
|
|
||
|  | ||
|
|
||
| So, once I have removed the backlight from the LCD's I can mount them in a frame. I can then begin to control the contrast/pixel density to make them dim. I will then add a LDR to automate the brightness selection, this will remove the manual adjust however I will leave the buttons to set the levels. Next I will add a camera to the system so that the system can also detect bright points hence make a matching point darker on the lens. I will then use the buttons to make it so that you can swap between the modes. The final additional feature I would like to add is some intelligence on the camera side to ignore certain circumstances such as car tail/headlights | ||

| # Report | ||
|
|
||
| I got the LCD hooked up and displayed some random spots of different opacity on the screen | ||

|
|
||
| I tried to install opencv to do the image processing built the install failed and after I spoke to my supervisor he confirmed my suspicion that opencv was too over powered for my project | ||
|
|
||
| so I did some more research around low power blob detection in python and found Skimage which has a function for Determinant of Hessian(doh) blob detection which should be quick enough the only issue I then had was getting the image from the camera into the right format since the doh blob need a numpy array as luck would have it skimage has a built in converter | ||
|
|
||
| I then connected the camera and started blob detection and got that working  | ||
|
|
||
| then I started to convert the shades.py (the file that controls the lcd and camera) and telegrambot.py (the script that enables remote control via a chat client bot) this involved more work than I had initially expected since passing variable around wasn't as easy as I had hoped | ||
|
|
||
| I decided to use telegram to add remote control so that you could adjust the colour of the tint [remote control](https://t.me/smartsheadsfypbot) | ||

||
| After I had all of the system working I bought a 5 button capacitive touch sensor and started adding that into the code so that I would be able to control the glasses with out having to have it connected to the internet | ||
