Insect Identification by photo
A significant problem with the transfer of goods in modern trade is that it has led to the spreading of harmful invasive species globally. This is especially true for wood boring beetles, as they can get introduced via shipped plants or plant material as well as the package wood itself. At the same time, the identification of these beetles is almost impossible for a layperson and requires years of training and practice, making it hard to distinguish between harmless and potential invasive species. As a result, most of the beetles found by plant health authorities in harbors, airports or warehouses do not get identified correctly.
The LTZ (Landwirtschaftliches Technologiezentrum Augustenberg) and Oculyze are meeting this challenge by using AI to automate the insect identification. The goal is to have a system that can be simply used by authorities to get a quick on-site diagnosis and which can help in the decision-making process for further steps.
Currently we are concentrating on the following species:
- Acanthocinus aedilis
- Aegosom sp. (A. scabricorne, A. sinicum)
- Agrilus sp. (A. anxius, A. bilineatus, A. mali, A. fleischeri, A. planipennis)
- Anoplophora sp. (A. chinensis, A. glabripennis)
- Aphrodisium faldermanni
- Apriona sp. (A. cinerea, A. germari, A. rugicollis)
- Aromia sp (A. bungii, A. moschata)
- Bactocera sp. (B. parryi, B. rufomaculata, B. lineolata, B. rubus rubus)
- Blepephaeus succinctor
- Chrysobothris sp. (C. femorata, C. mali)
- Dendroctonus sp. (D. adjunctus, D. brevicomis, D. frontalis, D. ponderosae, D. pseudosugae, D. rufipennis, D. valens)
- Derobrachus geminatus
- Dryocoetes confusus
- Euplatypus parallelus
- Euwallacea fornicatus
- Gnathotrichus sulcatus
- Ips sp. (I. calligraphus, I. confusus, I. grandicollis, I. hauseri, I. lecontei, I. paraconfusus, I. pini, I. plastographus, I. subelongatus)
- Petrognatha gigas
- Phymatodes testaceus
- Pityophthorus junglandis
- Polygraphus proximus
- Prionus sp. (P. californicus, P. coriarius)
- Pseudopityophthorus sp. (P. minutissimus, P. pruinosus)
- Massicus raddei
- Megaplatypus mutatus
- Monochamus sp. (M. alternatus, M. carolensis, M. marmorator, M. mutator, M. nitens, M. notatus, M. obtusus, M. scutellatus, M. titillator, M. sutor, M. sartor, M. galloprovincialis, M. sartor urussovii)
- Morimus sp. (M. asper asper, M. asper funereus)
- Nacerdes carniolica
- Neandra brunnea
- Obrium cantharinum
- Oemona hirta
- Saperda candida
- Scolytus morawitzi
- Tetropium gracilicorne
- Trichoferus campestris
- Trirachys sartus
- Turanoclytus namangansis
- Xylotrechus altaicus
- Xylotrechus chinensis
Under ideal conditions, a marker sheet of paper is used to allow estimation of size. The sheet has been designed to be cheap to mass produce or self-print. However, the detector has been developed to detect insects in different capture conditions including detection without a reference card.
When the image marker card is found, a dedicated software is applied. When no marker is found, the system switches to a more generic classifier; in this case, no size estimation will be possible.
Even at this early stage, for the species chosen, detection and classification are achieved with high confidence and accuracy. The algorithm has been trained to cope with challenging light and perspective conditions. Overall species and genus are correctly classified in most of the tests, even without the use of the reference card. For images captured using a reference card, confidence never goes below 90%, while accuracy remains very high.
