Texture Synthesis Repair of RealSense D435i Depth Images with Object-Oriented RGB Image Segmentation
Publikováno v:
Sensors, Vol 20, Iss 23, p 6725 (2020)
A depth camera is a kind of sensor that can directly collect distance information between an object and the camera. The RealSense D435i is a low-cost depth camera that is currently in widespread use. When collecting data, an RGB image and a depth ima
