In a Custom Dataset, Certain Categories Cannot be Detected: Troubleshooting Object Tracking with YOLOv8/YOLOv12 in ROS

Designing a strawberry-picking robot is an exciting project that requires the integration of various technologies, including computer vision and robotics. In this context, object tracking is a crucial component that enables the robot to detect and follow the strawberries. However, when working with a custom dataset, certain categories may not be detected properly, which can lead to inaccurate tracking and reduced performance. In this article, we will explore the possible causes of this issue and provide guidance on how to troubleshoot the problem.

The issue at hand is that certain categories are not detected properly when running object tracking with YOLOv8/YOLOv12 in a ROS package. This is in contrast to the results obtained when running direct prediction using Python and YOLO on a PC, where the performance is correct. The problem arises when the trained weights are imported into the ROS2 package and inference is run.

To troubleshoot the issue, let's analyze the problem step by step.

1. Dataset Verification

The first step is to verify that the dataset is correct. This involves checking the image quality, labeling, and formatting to ensure that they meet the requirements of the object tracking algorithm.

2. ROS Package Configuration

The next step is to review the ROS package configuration to ensure that it is set up correctly. This includes checking the input image topic, model, and other parameters to ensure that they are consistent with the requirements of the object tracking algorithm.

3. Inference Performance

The third step is to investigate the inference performance of the ROS package. This involves checking the processing time, memory usage, and other metrics to identify any potential bottlenecks or issues that may be contributing to the problem.

Based on the analysis, there are several possible causes of the issue:

1. Inconsistent Dataset

The dataset may not be consistent with the requirements of the object tracking algorithm. This could be due to issues with the image quality, labeling, or formatting.

2. Incorrect ROS Package Configuration

The ROS package configuration may not be set up correctly, leading to inconsistent results.

3. Inference Performance Issues

The inference performance of the ROS package may be affected by issues such as processing time, memory usage, or other bottlenecks.

4. Model Incompatibility

The model used in the ROS package may not be compatible with the object tracking algorithm, leading to inconsistent results.

To troubleshoot the issue, follow these steps:

1. Verify Dataset

Verify that the dataset is correct and consistent with the requirements of the object tracking algorithm.
