Embodiment Construction

[0080] RGB-D imaging systems incorporating ultrasonic depth or distance sensing may prove desirable and enable Provide the basis for a wide range of RGB-D imaging applications such as spatial imaging, gesture recognition, distance detection, 3D mapping, etc. Compared with the traditional RGB-D system, the ultrasonic array using beamforming can obtain a three-dimensional map including depth information without being restricted by ambient light interference. Additionally, ultrasonic sensors use significantly less power than RGB-D systems using infrared sensors, and thus may be suitable for mobile or active platforms, such as unmanned aerial vehicles (UAVs). by such as figure 1 The illustrated RGB-D imaging system 100 achieves these results in accordance with one embodiment disclosed herein.

[0081] turn to figure 1 , RGB-D imaging system 100 is shown including ultrasonic sensor array 110 operably connected to imaging device 120 and RGB camera assembly 130 operably connected ...

Abstract

The invention provides an RGB-D imaging system (100) for generating an image comprising depth data. The RGB-D imaging system (100) comprises an ultrasonic sensor array (110), wherein the ultrasonic sensor array (110) is used for generating depth map data through beam forming; and an RGB camera assembly (130) which is operatively connected to the ultrasonic sensor array (110), the RGB camera assembly (130) for generating RGB image data. Thus, the RGB-D imaging system (100) provides / is able to improve imaging under various illumination conditions as compared to conventional systems. The invention further provides a method for generating the RGB-D image.

Description

[0001] This application is a divisional application with the application number 201480075391.1, the application date is October 28, 2014, and the invention name is RGB-D imaging system and method using ultrasonic depth sensing. technical field [0002] The present invention relates to digital imaging, computer vision and ultrasonic sensing, and more specifically to RGB-D camera systems and methods. Background technique [0003] An RGB-D camera is a camera capable of producing three-dimensional images (plane two-dimensional images + vertical depth map images). RGB-D cameras usually have two different sets of sensors. One set of sensors includes an optical receiving sensor (eg, an RGB camera) for receiving an image of the environment, typically represented by the respective intensity values ​​of the three colors R (red), G (green), and B (blue). Another group of sensors includes infrared laser or structured light sensors to detect the distance (D) of the observed object and a...
