Dynamic human body pose recognition embedded platform in trunk shielding state

Abstract

The invention discloses a dynamic human body pose recognition embedded platform in a trunk shielding state, and the platform comprises two pieces of galvanized flat steel which are connected with eachother, and the galvanized flat steel fixes a laser radar sensor through a metal buckle. The laser radar sensor is in electric signal connection with the host, the TTL-to-USB conversion module, the internal communication module, the external communication module, the RS232-to-TTL conversion module and the auxiliary equipment in sequence. According to the invention, a reliable detection platform isprovided for human body dynamic pose identification in limb shielding and leg random standing states. A two-dimensional laser radar sensor and a laser radar are mainly used for recognizing leg contours at original positions, and the laser radar is additionally arranged on the basis to form an angle of 45 degrees with the horizontal plane and is used for detecting waist and back position distribution of a patient. The fusion of the two pieces of radar information can more accurately identify and distinguish the positions of the overlapped patient and nursing personnel.

Description

technical field [0001] The invention relates to the technical field of human-computer interaction, in particular to an embeddable detection platform for human body dynamic pose recognition in a state of body occlusion. Background technique [0002] In the process of nursing staff assisting people with disabilities to complete the necessary activities of daily life, getting up and transferring is the most frequent behavior, that is, the process in which people with disabilities are assisted from lying down to standing and finally transferred to sitting. Due to the lack of mobility and balance ability of the care receiver, and the transfer behavior is likely to have a large impact on the lower limbs and soles of the human body, it is extremely necessary for the nursing staff and auxiliary equipment to assist the whole process of transfer. Among them, identifying the dynamic posture of the patient's legs is the most critical. Based on the dynamic posture of the human body, the ...
