Strawberry Data

Data collection suite for strawberry data collection project. The standards document and example implementation can be found here.

Controls

| Key | Description | | --- | ----------- | | save, s, Enter Key | Writes all output to disk | | new, n | Creates new dataset folder and asks for meta data input | | laser0, l0 | Turns laser off | | laser1 <param>, l1 <param> | Turns laser on, <param> can be min(-3), mid(-2), max(-1) or any float value | | stab, st | Throws away frames for correcting exposure | | help, h | Displays help | | quit, q | Quits |

Config

Parameters are stored in the config.json file.

| Key | Description | | --- | ----------- | | save-path-prefix | Controls which folder the data structure is save in. Final path = save-path-prefix + data structure path | | project-name | Top level filter folder for organising different data collection sessions. Final path = save-path-prefix + project-name + "/" | | gui-enabled | If true all connected camera streams are displayed on screen, if true stabilise exposure can be false. | | stabilise-exposure | Throws away stabilise-exposure-count number of frames to stabilise the auto exposure | | stabilise-exposure-count | Parameter used when stabilise-exposure is true | | stream-colour | Parent property controlling stream parameters for colour sensors (see width, height and frame-rate) | | stream-depth | Parent property controlling stream parameters for depth sensors (see width, height and frame-rate) | | width | Sensor resolution width | | height | Sensor resolution height | | frame-rate | Sensor resolution frame rate | | options | Parent property that houses global sensor parameters (see auto-exposure, back-light-compensation and auto-white-balance) | | auto-exposure | Determines weather the sensor will determine exposure parameters using an internal algorithm | | back-light-compensation | This setting when on will compensate for very bright backgrounds to ensure more uniform lighting | | auto-white-balance | Determines weather the sensor can dynamically calculate the white balance parameters | | file-names | Contains all of the file names and extensions for multiple types (See for reference) |

Example Usage

```bash git clone https://github.com/RaymondKirk/StrawberryData mkdir -p StrawberryData/build cd StrawberryData/build cmake .. make all -j4 ./grabber

Application starts

...

Controls:

-save, s (Writes all output to disk)

-laser0, l0 (Turns laser off)

-laser1 , l1 (Turns laser on)

- can be min(-3), mid(-2), max(-1) or any float value

-stab, st (Throws away frames for correcting exposure)

-new, n (Creates new dataset)

-help, h (Displays help)

-quit, q (Quits)

Enter Control:

Enter the new command and start data collection

When finished press q to quit and repeat from #Application Starts
