|
## Device was created as part of a bachelor's thesis at BUT VUT 2022/2023 named Probe for Determining the Surface Condition of Small Diameter Barrels
|
|
|
|
|
## Detailed description of device design and implementation is inside thesis

|
|
|
|
|
|
|
|
### Models
|
|
|
|
|
|
|
|
|
|
- All 3D printable models are located inside Models folder
|
|
|
|
|
- Models are designed to be printed with standard 2mm layer height
|
|
|
|
|
- When slicing be sure to print outer walls first to make print more accurate
|
|
|
|
|
|
|
|
|
|
### Assembly
|
|
|
|
|
|
|
|
|
|
- All screws are size M3
|
|
|
|
|
- Assembly should be done accordingly
|
|
|
|
|
|
|
|
|
|
### PCB
|
|
|
|
|
|
|
|
|
|
- PCB should be two sided with 1.6mm width
|
|
|
|
|
- Design files are created in KiCad
|
|
|
|
|
|
|
|
|
|

## Firmware for profilometer probe
|
|
|
|
|
|
|
|
|
|
### Build
|
|
|
|
|
|
|
|
|
|
- Build using Makefile inside Firmware folder (dependency: arm-none-eabi)
|
|
|
|
|
- Flash onto hardware using flash option for make command `$ make flash`
|
|
|
|
|
|
|
|
|
|
### Usage
|
|
|
|
|
|
|
|
|
|
- Connect probe to pc using usb c cable and firmware will start sending sending data automatically
|
|
|
|
|
|
|
|
|
|
### Documentation
|
|
|
|
|
|
|
|
|
|
- Create documentation using 'doc' option of Makefile '$ make doc'
|
|
|
|
|
|
|
|
|
|
## Software for receiving data
|
|
|
|
|
|
|
|
|
|
### Build
|
|
|
|
|
|
|
|
|
|
- Build using Makefile inside Receiver folder
|
|
|
|
|
|
|
|
|
|
### Usage
|
|
|
|
|
|
|
|
|
|
- Has to be run with sudo permissions to correctly access USB CDC port.
|
|
|
|
|
- '$ sudo ./main -p <name of the port> [-s Save received jpeg to files] [-r Print raw received CDC data to standard output]'
|
|
|
|
|
- Prefer running with optional -s command for ability to inspect already captured images
|
|
|
|
|
|
|
|
|
|
### Documentation
|
|
|
|
|
|
|
|
|
|
- Create documentation using 'doc' option of Makefile '$ make doc'
|
|
|
|
|
|
|
|
|
|
### TODO
|
|
|
|
|
|
|
|
|
|
- Process image and filter only laser line from it
|
|
|
|
|
- Use precessed data to determine depth or height of irregularities
