Embodiment 1
[0052] This embodiment provides a method for generating motion trajectories, aiming to solve the problem of a large amount of power consumption caused by the continuous opening of the positioning device.
[0053] Specifically, refer to figure 1 As shown, the motion trajectory generation method includes steps S10 to S80.
[0054]Step S10, receiving the current acceleration fed back by the acceleration sensor and denoting it as a1. Wherein, the current acceleration a1 is a vector, which has a direction and a value. The acceleration sensor can be installed on the positioning device, or on the mobile terminal where the positioning device is located, and there is no limitation here, as long as the acceleration sensor and the positioning device can achieve the same motion trajectory.
[0055] Since the power consumption of the acceleration sensor is the lowest among all sensors, about 1 / 6 to 1 / 1 of the power consumption of other sensors, even if the acceleration sensor is turned o...
Embodiment 2
[0067] This embodiment provides a method for generating a motion track, and this embodiment is based on the first embodiment. Specifically, refer to figure 1 and figure 2 As shown, step S30 includes calculating the expected duration Ti in the i direction, i={x, y}, which may include steps S301 and S302.
[0068] Step S301, decompose the current acceleration a1 in the direction i to obtain the current acceleration component a1i, and decompose the velocity V1 in the direction i to obtain the velocity component V1i, where i={x, y}, it can be understood that x represents the longitude direction, y represents the latitude direction.
[0069] Step S302. Input the current acceleration component a1i and velocity component V1i into the first formula to obtain the expected duration Ti. The first formula is: Ti=A / |V1i+a1i*Td|, where A is a constant.
[0070] It is worth noting here that A can be regarded as a distance, which can be adjusted according to specific conditions. For exam...
Embodiment 3
[0084] This embodiment provides a method for generating a motion track, and this embodiment is implemented on the basis of Embodiment 1 and / or Embodiment 2. Specifically, refer to figure 1 and image 3 As shown, the method further includes step S80, which is after receiving the generating signal and before performing generating the motion track based on each positioning point in response to the generating signal. Step S80 specifically includes step S801 to step S807.
[0085] Step S801, querying the initial positioning point, and recording the next positioning point of the initial positioning point as a reference positioning point. The starting anchor point is the first anchor point to be processed in the processing set.
[0086] It is worth noting here that the processing set can be one, which contains all the positioning points to be processed; the processing set can also be multiple, and in each processing set, the time difference between adjacent positioning points conf...
