Data Set htwddKogRob-TSDReal for Localization and Lifelong Mapping


The outdated map and the robots driven path based on raw odometry data from run 2

This data set presents a 4.7 km long tour within an environment which's representation is meanwhile outdated. Several static objects have been moved or removed and there are a differing amount of dynamic obstacles present.

How to use

Within the zip archives are ascii files containing logs of robot observation and robot poses. If this data set was recorded in a simulated environment, the log contains an altered raw pose as well as a ground truth pose.

You can find more information in the log files header. To offer some help parsing the files, we give two Java-code snippets:

Laser Range Measurements:

        List<Double> ranges = new ArrayList<>(numOfLaserRays);
        List<Error> errors = new ArrayList<>(

        String s = line.substring(4);
        String delimiter = "()";
        StringTokenizer tokenizer = new StringTokenizer(s, delimiter);
            String[] arr = tokenizer.nextToken().split(";");
            boolean usable = (arr[0].equals("0")?false:true);
            double range = Double.parseDouble(arr[1]);


        String poseString = line.split(":")[2];
        String[] elements = poseString.substring(1, poseString.length()-1).split(";");
        double x = Double.parseDouble(elements[0]);
        double y = Double.parseDouble(elements[1]);
        double phi = Double.parseDouble(elements[2]);
