Insights from Drone Data for the Chainsaw Field Study
The utilization of processed photogrammetric drone data significantly contributes to unlocking valuable insights in our field study. We collected a comprehensive and detailed dataset of drone images. Proper planning and execution enabled us to cover a vast area in little time. We processed these images through the EDEO photogrammetry processing pipeline to generate highly accurate three-dimensional models of the study area.
By leveraging the georeferenced 3D models, we gain a deeper understanding of the spatial distribution of the forest and many required tree attributes such as canopy cover and vegetation density, but also tree heights and stem section measurements. These insights provide essential context for interpreting the data stream of the smart STIHL chainsaw in different areas within the study site.
Unveiling a Treasure Chest of Data
After the initial days of operation, the preliminary examination of the raw data reveals a promising and unique treasure chest which the iFOS team will evaluate in the upcoming weeks.
The sensors integrated in the chainsaw delivered valuable data, which was streamed directly to laptops for further analysis. This data collection process will provide comprehensive insights that enable us to examine critical parameters such as spatial positioning of the stem sections, wood dimensions and working efficiency.
The cooperation between our research team, the STIHL development team, the forest management of BaySF, and the dedicated forest workers played a vital role in the success of this very first field test. Their expertise and support greatly contributed to the smooth execution of the study and the acquisition of high-quality data.
The analysis process will involve precise examination of the recorded data, extracting patterns, trends, and correlations to derive meaningful insights and potential optimizations. We will use this information to develop software for deducing harvesting data from the raw data in real-time. We are eager to share our findings and contribute to the continuous evolution of smart forestry practices. Stay tuned for forthcoming updates as we embark on the evaluation phase.
Drone-Assisted Reference Data Collection for Smart Chainsaw Field Study
In the pursuit of enhancing the Smart Chainsaw field study, the integration of drone flights will further improve our data collection. With careful planning, we conducted drone flights over two study plots, amassing over 12 000 overlapping photos in the last two days. These images will be utilized to create accurate georeferenced photogrammetric models of the field plots. The drone-acquired reference data will be crucial in assessing the spatial positioning of the felled stem sections, as well as their dimensions.
With this valuable dataset at our disposal, we are excited to analyze and synthesize the information, further advancing the development and optimization of smart forest practices.
Field Study: Smart Chainsaw at BaySF’s Forstbetrieb Roding
The ongoing field study featuring the smart chainsaw is progressing well. Our current focus is testing the chainsaw in collaboration with “Forstbetrieb Roding” of BaySF, specifically in mixed forest stands with strong tree diameters. The recorded work steps include cutting a felling notch, making a felling cut, delimbing, and performing separation cuts. Raw data captured by the saw’s integrated sensor box is streamed to laptops and recorded for analysis.
The cooperation between our team and the forest management and workers of BaySF has been excellent. In the event of any issues with the prototypes, the STIHL developers are readily available by phone to provide quick assistance.
After the initial days of operation, a preliminary examination of the raw data reveals a promising and unique treasure chest which the iFOS team will evaluate in the upcoming weeks.
Smart STIHL Chainsaw – Upcoming Field Study
Our first field study in the Smart Forestry project is about to begin in the coming days. In this globally unique experiment, we will test a smart chainsaw from STIHL equipped with advanced capabilities. This innovative MS500i prototype chainsaw can detect its position and motion in space and simultaneously record important parameters from the powertrain, including engine speed.
The main objective of our study is to derive production parameters for the harvested wood. Similar to a harvester head, the chainsaw will accurately record the location and assortment of every stem section. This information will be invaluable within the context of Industry 4.0, as it can be shared instantly with other participants in the harvesting chain, such as skidders, forwarders and so on. This enables the seamless transfer of data regarding the dimension and position of the log sections.
We are excited to collaborate closely with esteemed partners including STIHL, BaySF, and RWTH Aachen University in the upcoming days for this field study.
