Abstract

The invention discloses an automatic obstacle avoidance trolley based on gesture recognition, relates to man-machine interaction intelligent image information processing, and belongs to the field of depth-camera-based non-contact three-dimensional virtual space and the field of binocular stereoscopic vision. Two separated cameras are arranged at the front portion of a trolley body. A lower computer comprising a single chip microcomputer is arranged inside the trolley body. The trolley body is provided with two wifi modules, wherein one wifi module is connected one camera. The trolley body is further provided with a Bluetooth module. Two trolley rear wheels are respectively connected with a precision direct-current motor. According to a control device of the automatic obstacle avoidance trolley, a depth motion-sensing camera is connected with an upper computer, and the upper computer is provided with a Bluetooth serial port and one wifi module. According to the automatic obstacle avoidance trolley based on gesture recognition, the trolley can be controlled through gestures, maps can be drawn, automatic obstacle avoidance of the trolley can be achieved in the automatic running mode, the automatic control, network communication and image processing technologies are utilized, operation is convenient, and the automatic obstacle avoidance trolley based on gesture recognition is suitable for inspecting whether a danger exists in the surrounding under the dangerous environment or not and conducting carrying work in the terrain with multiple obstacles.

Description

technical field [0001] The invention relates to human-computer interaction intelligent image information processing, belongs to the field of non-contact three-dimensional virtual space based on a depth camera and the field of binocular stereo vision, and specifically relates to an automatic obstacle avoidance car based on gesture recognition and its control device and control method. Background technique [0002] In the era of general intelligence of computers, human-computer interaction intelligent image information processing has become an important application in the field of computer vision. Since the emergence of PC in the 1990s, human-computer interaction, an interdisciplinary subject, has become the mainstream research technology of user experience. The emergence of somatosensory interaction mode has brought computer interaction technology into a new era. With the rigid demand of users for mobile smart devices that emerge in an endless stream, intelligent image proces...
