Abstract
Disclosed are a 3D laser scanning system and a method of obtaining a 3D image by using the system that detect, with a linear array type photo detector, a reflected light reflected from a target after rotation-emitting a line-shaped pulsed laser light through 360 degrees and obtain a 3D image through point cloud data obtained by measuring a distance to the target.
Claims21
A 3D scanning system emitting a line-shaped pulsed laser light, detecting a light reflected from a target, and generating a 3D image through point cloud data obtained by calculating the distance to the target, the 3D scanning system comprising:
- a laser source emitting a pulsed laser light,
- one or more light transmitting and receiving modules comprising a light transmitter that emits the pulsed laser light to the outside in a vertical line shape, and a photo detector that detects and converts the reflected pulsed laser light into an electrical signal;
- and
- a driving motor rotating the one or more light transmitting and receiving modules.
A 3D scanning system emitting a line-shaped pulsed laser light, detecting a light reflected from a target, and generating a 3D image through point cloud data obtained by calculating the distance to the target, the 3D scanning system comprising:
- a laser source emitting a pulsed laser light,
- two or more light transmitting and receiving modules comprising a light transmitter that emits the pulsed laser light to the outside in a vertical line shape, and a photo detector that detects and converts the reflected pulsed laser light into an electrical signal;
- and
- a driving motor rotating the two or more light transmitting and receiving modules;
- and
- wherein a light emission angle of at least one of the two or more light transmitting and receiving modules is different from that of the other light transmitting and receiving module.
A 3D scanning system emitting a line-shaped pulsed laser light, detecting a light reflected from a target, and generating a 3D image through point cloud data obtained by calculating the distance to the target, the 3D scanning system comprising:
