PlantDet: A benchmark for Plant Detection in the Three-Rivers-Source Region
The Three-River-Source region is a highly significant natural reserve in
China that harbors a plethora of untamed botanical resources. To meet the
practical requirements of botanical research and intelligent plant management,
we construct a large-scale dataset for Plant detection in the
Three-River-Source region (PTRS). This dataset comprises 6965 high-resolution
images of 2160*3840 pixels, captured by diverse sensors and platforms, and
featuring objects of varying shapes and sizes. Subsequently, a team of
botanical image interpretation experts annotated these images with 21 commonly
occurring object categories. The fully annotated PTRS images contain 122, 300
instances of plant leaves, each labeled by a horizontal rectangle. The PTRS
presents us with challenges such as dense occlusion, varying leaf resolutions,
and high feature similarity among plants, prompting us to develop a novel
object detection network named PlantDet. This network employs a window-based
efficient self-attention module (ST block) to generate robust feature
representation at multiple scales, improving the detection efficiency for small
and densely-occluded objects. Our experimental results validate the efficacy of
our proposed plant detection benchmark, with a precision of 88.1%, a mean
average precision (mAP) of 77.6%, and a higher recall compared to the baseline.
Additionally, our method effectively overcomes the issue of missing small
objects. We intend to share our data and code with interested parties to
advance further research in this field.Comment: 10 pages, 5 figure
