Abstract

The invention discloses a control method, comprising the following steps of: controlling a light emitter to emit a laser of a first frequency to the target to be tested; and controlling the light emitter to emit a laser of a second frequency to the object to be tested when the projection distance between the light emitter and the target to be tested is less than a first preset distance, wherein the second frequency is greater than the first frequency. According to the control method, the light emitter is controlled to emit the laser of the first frequency to the target to be tested, and the light emitter is controlled to emit the laser of the second frequency to the object to be tested when the projection distance obtained through the laser of the first frequency is less than the first preset distance, so that a projection distance with high accurate can be obtained through the laser light of the second frequency. The invention also discloses a control device, a time-of-flight device,a terminal, and a computer readable storage medium.

Description

technical field [0001] The present invention relates to the technical field of consumer electronic equipment, in particular to a control method, a control device, a time-of-flight device, a terminal and a computer-readable storage medium. Background technique [0002] Existing time of flight (Time Of Flight, TOF) devices are generally used to measure the distance between the target to be measured and the time of flight device, but the accuracy of the distance measured by the existing time of flight device is poor. Contents of the invention [0003] Embodiments of the present invention provide a control method, a control device, a time-of-flight device, a terminal, and a computer-readable storage medium. [0004] The control method in the embodiment of the present invention includes controlling the light emitter to emit a laser with a first frequency to the target to be measured, and controlling the The light emitter emits laser light with a second frequency to the target ...
