Embodiment Construction
[0026] Embodiments of the present invention are described in detail below, examples of which are shown in the drawings, wherein the same or similar reference numerals designate the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the figures are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.
[0027] see figure 1 and figure 2 , the control method of the embodiment of the present invention includes:
[0028] 01, controlling the light transmitter 21 to emit a laser with a first frequency to the target to be measured; and
[0029] 02. When the projection distance between the light emitter 21 and the target to be measured is less than the first preset distance, control the light emitter 21 to emit laser light with a second frequency to the target to be measured, and the second frequency is greater than the first frequen...

The control method disclosed in the present invention includes controlling the light emitter to emit laser light of the first frequency to the target to be measured, and controlling the light emitter to emit laser light of the first frequency to the target to be measured when the projection distance between the light emitter and the target to be measured is less than the first preset distance. The target emits laser light at a second frequency that is greater than the first frequency. The control method controls the light transmitter to emit the laser of the first frequency to the target to be measured, and when the projection distance obtained according to the laser of the first frequency is less than the first preset distance, controls the light emitter to emit the laser of the second frequency to the target to be measured. laser, so that the projection distance with higher precision can be obtained according to the laser with 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 ...
