This page contains several datasets of sugar beet fields spanning over multiple weeks for two different fields. The following table gives an overview of the datasets
|Field||Ses.||Date||# of images||crop size||weather|

|2||May 27||175||10 cm||sunny|
|3||June 17||121||15 cm||overcast|
|4||June 22||140||20 cm||cloudy|
|B||1||May 8||99||5 cm||sunny|
|2||June 5||95||15 cm||cloudy|
For the first field (A), we recorded the datasets across four sessions using a DJI MATRICE 100 UAV. The flight altitude for each session is between 8 m to 12 m above the ground. We recorded the images using the Zenmuse X3 camera with an image resolution of 4000 × 2250 pixels having a ground sampling distance of 4 mm per pixel at a height of 10 m.

For the second field (B), we used a DJI PHANTOM 4 UAV across two sessions recorded almost one month apart. The UAV was equipped with a GoPro camera set up to take an image every second at a resolution of 3840 × 2880. The flight altitude for the two sessions varied between 10 m and 18 m above the ground having a ground sampling distance of 9 mm per pixel at 15 m height.The average plant sizes in the fields range from 5 cm to 20 cm in diameter across the crop season.
