Embodiment Construction
[0109] In order to make the object, technical solution and advantages of the present invention clearer, the embodiments disclosed in the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0110] Such as figure 1 , in this embodiment, the firefighter gait and posture detection method includes:
[0111] Step 101, each time the firefighter takes a step, the corresponding basic state parameters are obtained through sensor measurement.
[0112] In this embodiment, in order to distinguish different action modes, for each step taken by the fireman, the following corresponding data are required (if the person is static, a new step is automatically entered every three seconds):
[0113] The step number index of the current i-th step: i;
[0114] Time T(i) from the start of the task to the current step i;
[0115] The vector position corresponding to the current i-th step in the earth coordinate system: P(i);
[0116] The att...

The invention discloses a firefighter gait and posture detection method, which comprises the following steps of: measuring corresponding basic state parameters through a sensor every time a firefighter steps out; deriving the basic state parameters to obtain extended state parameters; according to the basic state parameters and the extended state parameters of the firefighter, the movement gait or posture of the firefighter is judged in combination with a state judgment criterion; and the determined movement gait or posture data of the firefighter is transmitted back to the command end. According to the invention, an inertia processing layer is embedded, inertia data (speed, position and attitude angle) are independently analyzed to judge the action state of personnel, the action of fire fighters is analyzed, and the fire fighters are classified into normal walking, running, static, crawling, free falling, going upstairs, going downstairs and the like; according to the method, the properties of actions and postures of the firefighter are monitored in real time only through the inertial sensor installed on the foot, and flexible early warning is carried out under the condition that the firefighter is possibly unconscious and cannot communicate.
Description
technical field [0001] The invention belongs to the technical field of gait detection and physiological information detection, and in particular relates to a firefighter gait and posture detection method. Background technique [0002] Gait detection is an emerging biometric detection technology, and its main research application is to identify people by detecting the way people walk. Through different forms of movement, such as: walking, running, climbing, going up and down stairs, and the different forms of movement of body parts during free fall, to capture and judge specific movement behaviors of characters. [0003] The gait and posture of firefighters in the fire scene are difficult to be obtained by the command terminal outside the fire scene, and it is impossible to understand the movement status of firefighters. Those skilled in the art urgently need the above problems. Contents of the invention [0004] The technical solution of the present invention is to overco...
