LiDAR realtime odometry is the use of a LiDAR sensor to estimate the change in position over time. Using a 3D (360 degree) LiDAR for odometry typically results in very precise position change estimations. However, as no map is generated in this application, the position is always relative to the time you powered-on the LiDAR sensor (sensor initialization time is zero point). A 3D LiDAR will give you the following information relative to the starting time of the LiDAR:
When recording this information over time, you will get a 3D trajectory (dotted line):
The following owlRobotics LiDAR sensors are recommended for 3D odometry. Because the LiDAR needs to find enough points, there is a limit on the maximum speed and the size of the maximum open area you can use it. The expected position accuracy depends on many factors (speed, size of open area etc.).

A LiDAR sensor can be used to realtime-localize the sensor in the 3D world which means to compute the position of the LiDAR in the world. For robust localization, a 360 degree LiDAR is recommended. For outdoor localization, a 3D LiDAR (360 degree) is a must-have. While moving the LiDAR, software will generate a map of the world and localize the LiDAR in this world (also called ‘Simultaneous Localization And Mapping / SLAM algorithm’). For localization, the LiDAR does not need to have many rays as no precise maps are required for localization. When the LiDAR sensor is restarted at another location in the world (also called ‘LiDAR kidnapping’), the software can find the new position of the sensor in the map. This feature is called ‘relocalization’. The generated maps used to localize the sensor are not metric-correct and because of that you will get a misalignment when e.g. moving in a circle-like motion on the ground. The software will detect this misalignment and correct it. This feature is called ‘loop-closure’.

In mapping and scanning applications, the world is precisely measured to generate a 3D map of the world (or a 3D object). For precise mapping applications, the LiDAR should be able to 'shoot' at all points in the world. Often, for mapping applications, realtime is not required, and one can use 3D software (e.g. CloudCompare, MeshLab etc.) to improve the mapping results. A 3D LiDAR is required for outdoor applications and a 360 degree LiDAR helps to reduce the scanning time.

A LiDAR sensor can be used to recognize and track objects or to detect obstacles. Example objects are people, cars, traffic signs etc. Because a LiDAR sensor cannot detect colors but instead can detect reflectivity strength, you can detect black and white patterns with it.
Depending on your application, you can identify objects by:
