DESCRIPTION:During this Science Maker session we will aim to build a multi
 spectral camera and enclosure using equipment at the Cambridge Makespace. 
 Once they are finished\, we will take photographs in the surrounding area 
 and learn to process them!\n\nMultispectral imaging is a sensing technique
  where a spectrum is obtained for all of the points in an image of a scene
 \, allowing the user to detect signatures across different parts of the sp
 ectrum. In agriculture\, spectrum information gives good insights into cro
 p stress. multispectral cameras mounted on drones or aircraft allows quick
  assessments to be performed for yields across large areas of farmland\, a
 llowing for targeted use of fertilisers and irrigation.\n\nThis sensing te
 chnique is also used to classify different mineral groups\, monitoring ind
 ustrial emissions\, and to detect different pigments in antique art.\n\nPr
 ofessional multispectral cameras will typically cost ~£5000\, however exc
 ellent imaging for plants can be achieved using several NoIR camera module
 s (with filters) using a Raspberry Pi computer. Processing the images can 
 be done using online tools or by writing your own program (for example wit
 h OpenCV).\n\nThis event is jointly organised by the Cambridge Synthetic B
 iology (https://www.meetup.com/Cambridge-Synthetic-Biology-Meetup/)\, and 
 Sustainable Technology (https://www.meetup.com/Cambridge-Sustainable-Techn
 ology-Meetup/)groups.
