Datasets and Supporting Materials for the IPIN 2018 Competition Track 3 (Smartphone-based, off-site)

This package contains the datasets and supplementary materials used in the IPIN 2018 Competition (Nantes, France). Contents: IPIN2018_CallForCompetition_v2.1: Call for competition including the technical annex describing the competition 01-Logfiles: This folder contains a subfolder with the 22 training logfiles, a subfolder with the 15 (13 + 2) validation logfiles, and a subfolder with the 1 blind evaluation logfile as provided to competitors. 02-Supplementary_Materials: This folder contains the Matlab/octave parser, the raster maps, the vector maps and the visualization of the training routes. 03-Evaluation: This folder contains the scripts used to calculate the competition metric, the 75th percentile on the 99 evaluation points. The ground truth is also provided in MatLab format and as a CSV file. Since the results must be provided with a 2Hz freq. starting from apptimestamp 0, the GT includes the closest timestamp matching the timing provided by competitors. 03-Evaluation_alternative: This folder contains the alternative scripts used to calculate the competition metric, the 75th percentile on the 99 evaluation points. This version is compatible with MatLab and Octave and does not require any toolbox. In some cases, the differences in the reported errors might be around 10 cm with respect to the script used in the competition. The ground truth is also provided in MatLab format and as a CSV file. Since the results must be provided with a 2Hz freq. starting from apptimestamp 0, the GT includes the closest timestamp matching the timing provided by competitors.

IPIN2018_竞赛征集_v2.1：竞赛征集文件，包含描述竞赛规则的技术附件。 2. 01-日志文件：该文件夹包含三个子文件夹，分别存储22份训练日志文件、15份（13+2）验证日志文件，以及一份提供给参赛选手的盲测日志文件。 3. 02-辅助材料：该文件夹包含Matlab/Octave解析器、栅格地图、矢量地图，以及训练路线可视化文件。 4. 03-评估工具：该文件夹包含用于计算竞赛评价指标的脚本——即99个评估点上的75百分位误差。真值（Ground Truth, GT）以MatLab格式和CSV文件两种形式提供。由于参赛选手提交的结果需以2Hz频率从apptimestamp 0时刻开始，因此真值文件包含与参赛选手提供的时间戳最匹配的对应时间点。 5. 03-替代评估工具：该文件夹包含另一套用于计算竞赛评价指标的脚本，同样基于99个评估点的75百分位误差。此版本兼容MatLab与Octave，且无需依赖任何工具箱。在部分场景下，与竞赛官方使用的脚本相比，该版本报告的误差差异约为10厘米。真值同样以MatLab格式和CSV文件两种形式提供，且同样适配2Hz频率、从apptimestamp 0开始的时间要求，包含与参赛选手提供的时间戳最匹配的对应时间点。 使用本套件内数据集时，请引用以下文献： 1.
