Embodiment Construction
[0016] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.
[0017] In order to realize self-positioning without external reference equipment, the present invention uses itself as a reference point to obtain the motion direction and step length. Among them, the measurement of the step length can use the ranging technology based on RSSI (Received Signal Strength Indication) to measure the distance between nodes. The principle is to use the specific relationship between the received signal strength RSSI and the transmission distance d (the principle of RSSI ranging and positioning belongs to the existing technology, no more details), calculate the distance by measuring the signal strength.
[0018] Therefore, the present invention provides a motion trajectory acquisition method based on two-foot positioning, which takes the two feet alternately as a reference point, and detects the direction and step leng...
