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)
