The methodology of solid-state lidar is a highly advanced form of laser detection and ranging that employs laser pulses to measure the distance and velocity of an object. This technology uses an array of tiny laser emitters to create a high-desinity point cloud of the environment in which it is employed. It is capable of collecting data from a variety of angles and at different ranges, which allows for a more detailed analysis of the environment. Solid-state lidar is able to measure the reflectance of objects and calculate the surface area of each object. This data can be used to create detailed 3D models of the environment.

Solid state lidar offers several advantages when used in mobile mapping systems. One key advantage is the compact size and low power consumption, which allow the system to be used in many places that traditional scanning lidar systems cannot. Additionally, the laser beam is always active, so the system can quickly and accurately measure changes in the terrain. Finally, solid state lidar can measure even slight changes in elevation, providing more detailed and accurate results.

Workflow of the indoor mapping with solid state LiDAR

Indoor mapping with solid state lidar is a process that involves a range of components and steps.

1. To begin, a lidar scanner is mounted to a mobile platform, like a robot or a vehicle, and driven around the area to be mapped.

1. The lidar data can also be used to generate elevation models and digital surfaces, which can be used to further refine the map.
2. The map can also be used to create virtual replicas of the space, or to detect changes over time.

With solid state lidar, the entire process can be performed quickly, accurately, and safely.

Comparing Solid State LiDAR and Terrestrial LiDAR

There are two main types of lidar systems available for mobile mapping: mechanical and solid state. Mechanical lidar systems, also known as scanning lidar systems, use a rotating mirror to sweep a beam of laser light across the landscape. This type of system is typically more expensive and bulky, making them harder to implement on mobile mapping systems.

Solid state lidar systems are significantly smaller and require much less energy. Instead of a rotating mirror, these systems use a laser diode and a photodiode, which produce a laser beam that is constantly active. This allows for a much more accurate representation of objects in the environment, and the ability to measure even subtle changes in elevation over a large area. Advantages of Solid State Lidar

Solid state lidar and terrestrial lidar are both useful tools for collecting data about a given environment. However, there are some key differences between the two that should be considered when deciding which type of lidar is best suited for a particular application.

One key difference is the range of each type.
