The dataset generation failed because of a cast error
Error code: DatasetGenerationCastError
Exception: DatasetGenerationCastError
Message: An error occurred while generating the dataset
All the data files must have the same columns, but at some point there are 1 new columns ({'CH3'}) and 1 missing columns ({'CH4'}).
This happened while the csv dataset builder was generating data using

FPV Analog Video Signal Dataset for Real-time Detection
Description
This dataset contains captured analog CVBS (Color, Video, Blanking, and Sync) signals from FPV drones, specifically NTSC standard. The data was collected to support the development of signal processing algorithms for resource-constrained embedded systems (ESP32 and STM32).
Dataset Structure
The dataset is provided as a master index file and several compressed archives containing raw CSV signal data.
1. dataset_index.csv
The metadata file containing the following columns:
idx: Sample identifier.freq_ghz: The carrier frequency band (1.2, 3.3, or 5.8 GHz).category: Classification label (clos,degraded,non_reconstructible,noise_floor,interference).img_path: Path to the visual spectrogram/time-domain plot (found inimgs.zip).csv_vtx_path: Path to the source signal (Transmitter side).csv_vrx_path: Path to the captured signal (Receiver side).
2. Data Archives
12GHz.zip: Captures from the 1.2 GHz frequency band.33GHz.zip: Captures from the 3.3 GHz frequency band.58GHz.zip: Captures from the 5.8 GHz frequency band.imgs.zip: Supporting JPG visualizations for each sample.
Acquisition Setup
- Hardware: Custom RF front-end connected to Osciloscope.
- Sampling Rates: 5MSps
- Signal Conditions: Range from Clear Line of Sight (CLOS) to signals buried in the noise floor ($SNR < 0 \text{ dB}$).
Usage
To use the dataset with the provided paths in the CSV index, extract the archives into a data/ directory:
mkdir data
unzip 12GHz.zip -d ./data/12GHz/
unzip 33GHz.zip -d ./data/33GHz/
unzip 58GHz.zip -d ./data/58GHz/
unzip imgs.zip -d ./data/imgs/
