The invention discloses an ultrasonic
gait detection device and method. The method is characterized by comprising the following steps: installing an
ultrasonic detection system in front of a walking aid
robot platform, respectively detecting the distance between the left and right legs of the testee and the
ultrasonic detection platform by multiple ultrasonic sensors, extracting
gait information in the walking process of the
human body, and analyzing and calculating
gait parameters, including average step length, average pace,
step frequency,
instantaneous speed and the like. The device comprises an ultrasonic
transceiver, a
data acquisition and transmission device, a gait
data processing unit and a gait characteristic parameter calculation and analysis unit. The detection device is installed on the walking aid
robot platform, and no device is installed on the testee body, so that the ultrasonic gait detection device can detect the gait of the testee without any restriction, thereby reducing the
mental load of the testee in the gait detection process; the extracted gait characteristic parameters are more accurate; and the detection
system has the advantages of simple structure and low cost, and is convenient to use and install.
