RGB-D SLAM: A Review of Methods and Performance Trade-Offs for Different Requirements

Sensors
The RGB-D (Red, Green, Blue plus Depth) camera is a widely used onboard sensor for Simultaneous Localization and Mapping (SLAM), as it captures RGB images and depth information simultaneously. This capability has made RGB-D SLAM a topic of broad research

A visual simultaneous localization and mapping approach based on scene segmentation and incremental optimization

International Journal of Advanced Robotic Systems, 2020
Existing visual simultaneous localization and mapping (V-SLAM) algorithms are usually sensitive to the situation with sparse landmarks in the environment and large view transformation of camera motion, and they are liable to generate large pose errors ...

Compressive Temporal RGB-D Imaging

, 2017
We report a compressive imaging system for high-speed color (RGB) video and range sensing based on the structured illumination. Random patterns are projected on the scene at a higher frame rate than that of the color camera.

Extrinsic RGB-D camera calibration for legged robots

, 2011
This paper describes a method to identify the extrinsic parameters of RGB-D cameras mounted on legged robots. Since the calculation of the parameters is based on the detection of the robots feet in the camera images, no special calibration objects are ...

RGB-D foreground extraction from a moving camera using nonlinear pixel classification

, 2017
We propose a foreground extraction method from a freely moving RGB-D video camera that uses a nonlinear optimization function to classify pixels in every frame as either foreground or background. The method starts with extracting sparse features in every

Fruit recognition method for a harvesting robot with RGB-D cameras

ROBOMECH Journal, 2022
In this study, we present a recognition method for a fruit-harvesting robot to automate the harvesting of pears and apples on joint V-shaped trellis. It is necessary to recognize the three-dimensional position of the harvesting target for harvesting by ...

AN RGB-D DATA PROCESSING FRAMEWORK BASED ON ENVIRONMENT CONSTRAINTS FOR MAPPING INDOOR ENVIRONMENTS [PDF]

ISPRS Annals of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2019
The adoption of RGB and depth (RGB-D) sensors for surveying applications (i.e., building information modeling [BIM], indoor navigation, and three-dimensional [3D] models) to replace expensive and time-consuming methods (e.g., stereo cameras, laser ...

LMA based emotional motion representation using RGB-D camera

, 2013
In this paper, emotional motion representation is proposed for Human Robot Interaction: HRI. The proposed representation is based on 'Laban Movement Analysis: LMA' and trajectories of 3-dimensional whole body joint positions using an RGB-D ...
