Compact solid-state vertical-cavity-surface-emitting-laser beam scanning module with ultra-large field of view

“…As the eye of intellectualization, a 3D sensing technology is facing a big breakout of global markets, such as time-of-flight (ToF) light detection and ranging (LiDAR) 1,2) in automotive and structured-light sensing in face identification (Face ID). 3,4) Currently, a flash light source, such as vertical-cavity surface-emitting laser (VCSEL) array 5,6) and light-emitting diode (LED), 7,8) are mostly applied in 3D sensors to illuminate targets. In contrast, a scanning light source has obvious advantages of better signal to noise ratio 1,2) and avoiding ghost images due to multi reflections.…”

Depth map artefacts reduction: a review

“…As all of these mentioned depth maps have geometrical information, they are exploited in a variety of visual communication and computer vision applications that benefit from this information such as robotics navigation, gesture recognition, 3DTV [8], mobile phone [9], 3D reconstruction [10], human pose estimation, and so on. One of the important applications used for detecting and modelling the objects in a scene is 3D reconstruction.…”

CMOS Depth Image Sensor with Offset Pixel Aperture Using a Back-Side Illumination Structure for Improving Disparity

“…Presently, a wide variety of studies are being conducted on 3D image sensor technology. Typical 3D imaging methods include time of flight (ToF), structured light, and stereo vision [ 1 , 2 , 3 , 4 , 5 , 6 , 7 , 8 , 9 , 10 , 11 , 12 , 13 , 14 , 15 , 16 , 17 ].…”
