Export Result Description
Description for BasicAI Export Format
When exporting data and annotation results in BasicAI format, the ZIP architecture will be as follows:
.
├── data // Data info
│ ├── data1.json
│ ├── data2.json
├── result // Annotation result, more details can reference "Data Annotation Result" section
│ ├── data1.json
│ └── data2.json
If there are Batches and Scenes, additional levels will be added above Data & Result in the ZIP structure.
BasicAI Image Format
The coordinate origin is in the upper left corner of the image.

BasicAI LiDAR Fusion Format
Due to the large amount of data in a single dataset, the data file cannot be directly exported. Only the data information, including the download address, can be exported.

BasicAI Point Cloud Segmentation Format
The results of BasicAI Point Cloud Segmentation are comprised of two components: JSON and PCD files.
JSONstores the mapping between point numbers (in the "no" field) and their corresponding labels.PCDstores the numbers of all points, where points with the same number belong to the same segmentation result. Points correspond one-to-one to the original upload file.
NOTE
The uploaded point cloud on the platform may have some misaligned points due to the preprocessing. It is recommended that you verify this independently.
The ZIP architecture of BasicAI Point Cloud Segmentation Format can be described as follows:
.
├── data // Data info
│ ├── data1.json
│ ├── data2.json
├── result // Annotation result, more details can reference "Data Annotation Result" section
│ ├── data1.json
│ ├── data1_segment.pcd
│ ├── data2.json
│ └── data2_segment.pcd
You can run the following function (Python) to read the PCD file:
import re
from pathlib import Path
import numpy as np
def load_segmentation(
segmentation_file: Path
):
data = re.search(rb'\nDATA .*?\n([\s\S]*)', segmentation_file.read_bytes()).groups()[0]
return np.frombuffer(data, dtype=np.uint8)
