This repository contains TextSLAM-Dataset, the Text-oriented Semantic Dataset.

Overview

⭐ TextSLAM-Dataset is A Robust and Expansive Text-oriented Semantic Dataset covering various real-world scenarios, both indoor and outdoor, accompanied by comprehensive ground truth:

• This is the First Text-oriented dataset for SLAM method.
  
• Cover diverse Indoor and Outdoor scenes, including Rich Scene Texts with various sizes, fonts, languages, and backgrounds.
  
• Cover real-world complex environments with Rich Semantic Objects and multiple challengings, such as complex occlusion, glass reflection, dynamic pedestrians, and illumination changes.
  
• Provide Pose and Mapping Ground Truth with high precision.
  
• Provide Image Retrieval Ground Truth for Day-Night sequence, serving as a valuable resource for Visual Localization tasks.
  

⭐ Dataset Overview:

• Comprise a total of 36 sequences covering a mix of indoor and outdoor scenes.
• Utilizing the depth-camera Intel RS-D455 for data collection.
• Provide text extraction results within sequences for fair comparisons. The text detection and recognition results in this paper are from AttentionOCR. Note that more advanced text extractors can be integrated if they are available.
• Refer our paper to find the performance of state-of-the-art SLAM algorithms in this dataset.

Dataset Download

We provide sequences according to their collection scenes respectively. In the Download Table, the 'All' link allows users to download all the data within a single sequence. Additionally, individual item download links ('Images', 'Texts', 'Ground Truth', 'Image List') are provided in the following columns.

A. Indoor Scene Download

Overview of Indoor Environment & Sensors

 

➡️ Indoor sequences (10 sequences) : BaiduYun Link, Google Link
Refer to yaml/GeneralMotion.yaml in TextSLAM algorithm and Table-2 in our paper.

➡️ Indoor sequences for loop test (8 sequences): BaiduYun Link, Google Link
Refer to yaml/AIndoorLoop.yaml in TextSLAM algorithm and Table-4 in our paper.

B. Large Indoor Scene Download

Large Indoor Environment

 

➡️ Large Indoor sequences for loop test (9 sequences): BaiduYun Link, Google Link
Refer to yaml/LIndoorLoop.yaml in TextSLAM algorithm and Table-5 in our paper.

C. Outdoor Scene Download

Outdoor Environment & Sensors

 

➡️ Day Sequences (8 sequences): BaiduYun Link, Google Link
Refer to yaml/Outdoor.yaml in TextSLAM algorithm and Table-6 in our paper.

➡️ Night Sequences (1 sequence): BaiduYun Link, Google Link
Refer to Figure-23 in our paper.

Notation:

The structure of each file is as follows:

<Sequence name>
│
├── <images>
├────────	[timestamp].png
├──────── .......
├── <text>
├────────	[timestamp]_dete.txt		   // detection result for [timestamp].png. Each line: u1,v1,u2,v2,u3,v3,u4,v4
├────────	[timestamp]_mean.txt		   // recognition results for [timestamp].png. Each line: meaning, confidence
├──────── .......
├── <Exper.txt>                      		  // image list for this sequence
├── <gt.txt>                         		  // Each line (TUM format): timestamp tx ty tz qx qy qz qw
<Intrinsic Parameters>          		  // First line: fx, fy, cx, cy; Second line: k1, k2, p1, p2, k3

For night sequence:

<match_gt.txt>                     		  // Each line: [night_image_name].png [matched day_image_name].png

Specifically, the [matched day_image_name].png is from Seq_02 in the 4_Outdoor sequences.
