Area Computation by the Alternative Coordinate Method

49
The alternative coordinate method, also known as the Shoelace Formula, is a technique for determining the area of a traverse using Cartesian coordinates. This method relies on the sequential arrangement of x and y coordinates for each point of the shape, ensuring accuracy and ease of application.In this approach, each corner's x and y coordinates are listed as fractions, with the x-coordinate as the numerator and the y-coordinate as the denominator. These coordinates are arranged sequentially...

Area of Science:

  • Computer Vision
  • Machine Learning
  • Robotics

Background:

  • Object detection models like YOLOv8 face challenges in complex scenarios, including large parameter counts and computational demands.
  • Efficient detection of race cones and buckets is crucial for autonomous vehicle competitions, such as the Formula Unmanned Competition.

Purpose of the Study:

  • To develop a lightweight object detection model based on YOLOv8 for improved efficiency in detecting race cones and buckets.
  • To address limitations in complex structure, parameter redundancy, and computation affecting detection performance.

Main Methods:

  • Proposed a lightweight detection model by enhancing the backbone network (using YOLOv9's ADown module), neck network (replacing YOLOv8 C2f's fusion module with FasterNet's FasterBlock), and detection head.
  • Integrated knowledge distillation to further optimize detection performance.
  • Utilized the FSACOCO dataset for experimental validation.

Main Results:

  • The improved model achieved an accuracy of 92.7%, recall of 84.6%, and average precision of 91% on the FSACOCO dataset.
  • Demonstrated a 2.7% increase in recall and 1.2% increase in average precision compared to the original YOLOv8n model.
  • Reduced model memory by 50% and computation by 51%, while significantly decreasing misdetections and ensuring high detection speed.

Conclusions:

  • The developed lightweight YOLOv8 model effectively enhances the detection of race cones and buckets, meeting the stringent requirements for deployment on tiny devices in autonomous racing.
  • The proposed improvements offer a viable solution for object detection in complex environments and can be extended to other small target detection tasks.
