The ' Know what you ’re growing ' ( Weet wat er leeft ) project aims to combine different monitoring data into one overview of species present in greenhouses . One of these data point streams come from automatic image credit . Bruce Schoelitsz , HAS green academy student , share developments made over the past class . One of the problems HAS green honorary society students encountered last class was the essence of bleached LED lighting in greenhouses on the carrying into action of the image recognition model . Insects in pictures of chicken sticky plates taken with speech sound were no longer recognised . A new grouping of students tackled this and investigate how to solve that problem . As it turned out , both using a strong outside flash , and adjusting the gloss of the picture in post - processing , secure that the insects were recognised just as well as under white Christ Within . This worked better than train a new example with the purple Light Within .
effigy recognition model in practiceIn addition , the paradigm identification poser was tested in practice . The results of the model were unsatisfying in greenhouses of rose , pot orchidaceous plant , chrysanthemum and cucumber . The number of individual of the pest specie the model was train on was very low . Furthermore , several greenhouses contain specie that were not present in the pic the model trained on . As a result , they were often wrongly recognised as pestilence mintage . In other greenhouses , the density of other insects was so high that , for example , thrips could not be easily control among all the leg and wing .
The pic taken in the field will be used after the summertime to retrain the model . This is expected to greatly improve the model and enable it to determine tendency in numbers of thripid , whiteflies , aphids and parasitic wasps . To well analyze the photos and make the data easily understandable , the app developed by imec will be further acquire . The data will be made insightful within a LetsGrow module . For right further development , user experience are important and growers already involved in the project will be meet .
foliage materialBesides pic of sticky trays , the Edapholog was also used . This is a funnel into which leaf textile can be set that is heated with a lamp . Crawling insects and soupcon walk down and then land on a small platform that is take . These pic can be used to train recognition models and these have now been made by Edaphone for Swirskii , Montdo , the eating jot Carpoglyphus lactis and thrips larvae . The next footstep is to determine the accuracy and improve the models .
