A Path Planning Algorithm Based on Tangent Point Search and Constrained B‐Spline

open access: yesJournal of Field Robotics, EarlyView.
ABSTRACT The traditional Tangent Point Search (TPS) algorithm, as a path planning algorithm suitable for large‐scale maps, performs well in the presence of large rectangular obstacles. However, it has two disadvantages: 1. it requires that the obstacles be rectangular so that the shape of obstacles is limited to the fixed form. 2.

How to achieve accurate wildlife detection by using vehicle‐mounted mobile monitoring images and deep learning?

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
This paper introduces an enhanced Yolo‐v7 model, namely Yolo‐v7(sr‐sm), which integrates a super‐resolution (SR) reconstruction module and a small object optimization module for vehicle‐mounted mobile monitoring of wildlife. We obtained images of four wildlife species (sheep, birds, deer, and antelope) on the Tibetan Plateau and constructed a wildlife ...
