Linked  to this, the measurement of changes in the external structure and phytomorphology of plants is of particular interest. In the fields of environmental research and agriculture, an inexpensive and field-applicable on-site imaging technique to derive three-dimensional information about plants and vegetation would  represent a considerable improvement  upon existing monitoring strategies. This is particularly true for the monitoring of plant growth  dynamics, due to the often cited lack of morphological  information. To this end, an innovative  low-cost light-field camera, the Lytro LF (Light-Field), was evaluated in a long-term field experiment. The experiment showed that the camera is suitable for monitoring plant growth dynamics and plant traits while being immune to ambient conditions. This represents a decisive contribution for a variety of monitoring and modeling applications, as well as for the validation of remote sensing data. This strongly confirms and endorses the assumption that the light-field camera presented in this study has the potential to be a light-weight and easy to use measurement tool for on-site environmental monitoring and remote sensing purposes.<\/jats:p>","DOI":"10.3390\/rs8100823","type":"journal-article","created":{"date-parts":[[2016,10,10]],"date-time":"2016-10-10T10:35:19Z","timestamp":1476095719000},"page":"823","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":26,"title":["Imagine All the Plants: Evaluation of a Light-Field Camera for On-Site Crop Growth Monitoring"],"prefix":"10.3390","volume":"8","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-2888-0834","authenticated-orcid":false,"given":"Robert","family":"Schima","sequence":"first","affiliation":[{"name":"Department Monitoring and Exploration Technologies, UFZ \u2013 Helmholtz Centre for Environmental Research, Permoser Stra\u00dfe 15, Leipzig 04315, Germany"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4746-9143","authenticated-orcid":false,"given":"Hannes","family":"Mollenhauer","sequence":"additional","affiliation":[{"name":"Department Monitoring and Exploration Technologies, UFZ \u2013 Helmholtz Centre for Environmental Research, Permoser Stra\u00dfe 15, Leipzig 04315, Germany"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1406-9554","authenticated-orcid":false,"given":"G\u00f6rres","family":"Grenzd\u00f6rffer","sequence":"additional","affiliation":[{"name":"Chair of Geodesy and Geoinformatics, University of Rostock, Justus-von-Liebig-Weg 6, Rostock 18059, Germany"}]},{"given":"Ines","family":"Merbach","sequence":"additional","affiliation":[{"name":"Department of Community Ecology, UFZ \u2013 Helmholtz Centre for Environmental Research, Theodor-Lieser-Stra\u00dfe 4, Halle 06120, Germany"}]},{"given":"Angela","family":"Lausch","sequence":"additional","affiliation":[{"name":"Department of Landscape Ecology, UFZ \u2013 Helmholtz Centre for Environmental Research, Permoser Stra\u00dfe 15, Leipzig 04315, Germany"}]},{"given":"Peter","family":"Dietrich","sequence":"additional","affiliation":[{"name":"Department Monitoring and Exploration Technologies, UFZ \u2013 Helmholtz Centre for Environmental Research, Permoser Stra\u00dfe 15, Leipzig 04315, Germany"}]},{"given":"Jan","family":"Bumberger","sequence":"additional","affiliation":[{"name":"Department Monitoring and Exploration Technologies, UFZ \u2013 Helmholtz Centre for Environmental Research, Permoser Stra\u00dfe 15, Leipzig 04315, Germany"}]}],"member":"1968","published-online":{"date-parts":[[2016,10,7]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Purkis, S., and Klemas, V.
