We handle everything from drone flight to forest analysis.
We have set up a system to implement it all at once.
In the future, anyone can easily own a drone.
Aiming for a world where forest surveys can be carried out,
Including technical lectures on drone operation, etc.
Creating various types of support.
Preliminary Checks / Planning
Formulation of measurement plan
We will discuss the purpose and the area to be photographed.
● Preliminary Checks
・Confirmation of target area and terrain conditions
・Verification of flight permission requirements, etc.
● Planning
・Drone selection
– Type: Camera-only or camera with LiDAR
– RTK positioning: Enabled / Disabled
・Flight and survey planning
Matrice350 RTK
LiDAR：Zenmuse L1/L2
Mavic3 enterprise RTK
Drone Flight
Autopilot based on measurement plan
Perform contour flight
The drone flies according to the terrain.
A flight route that follows detailed terrain is created in advance using special software, and images are taken safely while maintaining a constant altitude and image quality.
Reproducing a forest from images using image processing
By combining the many images obtained, the forest is
recreated in three dimensions.
Creates a high-resolution image that provides a bird’s-eye view
of a wide area of forest.
● Data processing for analysis
・Creation of ortho/DSM images using SFM technology
・Creation of DTM images by filtering processing
(During laser measurement) DF LAT
Orthomosaic
DSM
DTM
Creating Data for Analysis
Separate individual trees based on images
Determine the number, type, volume, etc.
Add the following analysis results to the attribute information.
It is possible to output in Shape file format (GIS standard format).
Tree Crown Segmentation
Unique technology based on image information and 3D information
to detect the tree top and the range of individuals.
This allows us to understand the number and density of each tree,
Subsequent analysis is possible.
Tree Species Identification
We perform detailed tree species identification using deep learning using patent-pending technology.
Coniferous trees such as cedar and cypress have over 90%
Can be identified with precision.
Size Estimation
The tree height, thickness (DBH), and trunk volume are estimated for each tree.
Tree crown area, tree species, and tree height information are used to estimate the thickness.
Report / Delivery
We will report the results and deliver the results.
The delivered items included orthoimages, 3D data, and information about each tree.
We deliver polygon data in a format compatible with GIS.
