ToF, by rapidly acquiring depth information, can quickly generate 3D point cloud data of objects. It directly calculates the length, width, height, and volume without requiring physical contact and is unaffected by the object's shape and surface texture. Additionally, its measurement speed is fast, and it can be seamlessly integrated into automated equipment, effectively meeting the needs for precise, efficient, and non-contact volume measurement in scenarios such as warehouse billing, parcel sorting, and loading optimization.
