101, acquiring at least two detection optical signals, and determining the detection optical signal with the optimal performance as a target detection optical signal from the at least two detection optical signals.

First, the optical signal transmitting apparatus randomly transmits N probe optical signals including respective transmission angles, and thus the N probe optical signals transmitted by the optical signal transmitting apparatus can cover a very wide range. The optical signal transmitting device can be suspended and arranged at a high position, such as the top of a room. So that it is possible to cover the whole room. And the light is emitted through each reflecting surface, so that the indoor full coverage is basically realized. The device to be charged can receive the detection light signal no matter which position the device to be charged is arranged at, and also receive at least two detection light signals, wherein the at least two detection light signals comprise a detection light signal which is directly emitted to the device to be charged by the light signal emitting device, a detection light signal which reaches the device to be charged after one or more reflections, a detection light signal which reaches the device to be charged after refraction, and the like.

After the charging equipment acquires the at least two detection light signals, screening is carried out on the at least two detection light signals, and the detection light signal with the optimal performance is screened out to be the target detection light signal.

The detection optical signal may be an invisible optical signal or a visible optical signal, or may be a laser signal or an infrared signal.
