Special Issue Information

Dear Colleagues,

This Special Issue welcomes the contribution of studies focusing on innovative sensors, measurement solutions, and data analysis methods for application in the precision agriculture and food quality assessment research fields. Examples include (but are not limited to):

  • hybrid measurements in crop fields or forestry regions to analyze the status of plants (health, growth, presence of pests or diseases)
  • remote sensing technologies (e.g., drones) for large-scale crop health monitoring and yield prediction
  • measurements on food either in the production line or afterwards to assess their quality before consumption or mixing with other ingredients to obtain processed food
  • optical, chemical, electronic sensors for quality controls food and the identification of food fraud and adulteration
  • food safety sensors for detecting contaminants or pathogens in food products or tracking freshness or spoilage during processing, packaging, and transportation
  • sensor systems for soil and water quality monitoring in agricultural environments, assessing key parameters like moisture levels, pH, and nutrient content
  • IoT-based solutions for real-time tracking of environmental conditions in greenhouses or controlled agricultural systems

Topics of interest include data collection, modeling and analysis, interpretation, and elaboration of results.
Studies that explore and/or develop novel data analysis techniques, including artificial intelligence, contactless sensors, and applications in uncontrolled environments, will be of particular interest.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Sensors is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

This article describes the development, experimental validation, and uncertainty analysis of a simple-to-use model for monocular depth estimation based on optical flow. The idea is deeply rooted in the agricultural scenario, for which vehicles that move around the field are equipped with low-cost cameras. In the experiment, the camera was mounted on a robot moving linearly at five different constant speeds looking at the target measurands (ArUco markers) positioned at different depths. The acquired data was processed and filtered with a moving average window-based filter to reduce noise in the estimated apparent depths of the ArUco markers and in the estimated optical flow image speeds. Two methods are proposed for model validation: a generalized approach and a complete approach that separates the input data according to their image speed to account for the exponential nature of the proposed model. The practical result obtained by the two analyses is that, to reduce the impact of uncertainty on depth estimates, it is best to have image speeds higher than 500–800 px/s. This is obtained by either moving the camera faster or by increasing the camera’s frame rate. The best-case scenario is achieved when the camera moves at 0.50–0.75 m/s and the frame rate is set to 60 fps (effectively reduced to 20 fps after filtering). As a further contribution, two practical examples are provided to offer guidance for untrained personnel in selecting the camera’s speed and camera characteristics. The developed code is made publicly available on GitHub. Full article
