- Estimação do volume de um espaço interior com LiDARPublication . Bierende, Jaqueline; Lima, José; Pereira, Ana I.; Braun, João; Bertotti, Fábio Luiz3D scanning is a task of great importance for our modern society and has brought great advance when it comes to precision of inventory. These sensors measure and map the material surface continuously, allowing real-time inventory monitoring. This work presents the simulation of a low-cost 3D scanning system based on timeof- flight, that after a voxelization process, performs the volume estimation of an object filled indoor space. The Evolid system consists of a 2D LiDAR scanner performing 180º variation. Through coupling in a stepper motor, the sensor also moves on the tilt axis, allowing threedimensional mapping. The system and methodology developed were implemented and validated through SimTwo, a realistic simulator. Subsequently, the approach for data collection in the real environment was tested, demonstrating that a developed solution met the proposed objectives. Finally, possible works to be foreseen in future works are highlighted.
- Volume estimation of an indoor space with LiDAR scannerPublication . Bierende, Jaqueline; Braun, João; Lima, José; Pereira, Ana I.Three-dimensional scanning is a task of great importance for our modern society and has brought great advance when it comes to precision of inventory. These sensors measure and map the material surface continuously, allowing real-time inventory monitoring. As this process is very complex, most technologies are expensive, and even low-cost ones are a good investment option for the average user. Therefore, this work presents the simulation of a lowcost Time-of-Flight based 3D scanning system, that after a voxelization process, performs the volume estimation of an object filled indoor space. The system consists of a 2D LIDAR scanner that performs a 180º degrees sweep through a stepper motor.
