From the above, the present invention has the following features:

1. the virtual scene of the present invention may be a specific actual scene, and is not limited to only a virtual scene. The conversion mode is that energy consumption is used as a medium, the speed and time of movement are not simply mapped into a map, and if the movement is mapped onto the map directly through the movement speed, the energy consumed by different people is judged through the direct distance between two points on the map, which is not scientific. The invention maps the actual movement to the virtual scene by taking the energy consumption as an intermediate variable, the consumed energy of the actual movement is not changed, but the movement distance of the actual movement in the virtual scene is changed, and the movement consumption of the actual movement is judged by the distance in the virtual scene, so the result is accurate and has high reference significance.

2. If the actual movement speed is multiplied by the movement time to directly calculate the movement distance under different geographic environments, the calculated result is seriously inconsistent with the actual movement result because the different geographic environments have larger influence difference on the body energy consumption of the human body, for example, the walking speed on a plain is directly used for calculating the movement distance in a high-altitude area, because the human body is influenced by factors such as altitude, climate and the like, the energy consumed by the human body is far larger than the consumption on the plain, the movement distance is far smaller than the calculated distance in the same time in the actual movement process, therefore, the calculation of the movement distance under another geographic environment according to the movement speed under one geographic environment is not scientific, but the invention can well solve the problem, the invention takes the energy consumed by the movement as a medium to map the measured energy consumed by the actual movement of the human body into the energy consumed by the virtual movement, the distance of the virtual motion in the motion path of the virtual scene is obtained, and then the motion end point of the virtual motion is obtained, so that the motion distance in another geographic environment can be well calculated.

The preferred embodiments of the present invention described above are only for illustrating the embodiments of the present invention and are not to be construed as limiting the objects of the invention described above and the contents and scope of the appended claims, and any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present invention still fall within the technical and claim protection scope of the present invention.
