Security factor acquisition method and related device

The invention provides a safety factor obtaining method and a related device. According to the technical scheme of the invention, the method comprises the steps: obtaining a real distance between a first device and a first obstacle in a first time period; determining a safety factor of the first equipment according to the real distance in the first time period and a safety distance in the first time period, wherein the safety distance in the first time period corresponds to a preset safety distance rule; wherein the safety factor is obtained at least through a first similarity between a first mapping relation and a second mapping relation, the first mapping relation is a mapping relation between a real distance and time in the first time period, and the second mapping relation is a mapping relation between a safety distance and time in the first time period. According to the technical scheme, the real distance and the safety distance of the first equipment in the first time period are acquired, so that the sa
