Abstract

The embodiment of the invention provides a method for controlling power dissipation and terminal equipment, and relates to the technical field of communication. The problem in the prior art that a mode of adopting fixed pulse width for emitting pulse light signals cannot meet the using requirements of different scenes is solved. The method comprises the steps of obtaining a first distance, whereinthe first distance is the distance between the terminal equipment and a target object; obtaining emitting parameters for emitting target pulse light signals of the terminal equipment according to thefirst distance; emitting the target pulse light signals according to the emitting parameters, wherein the emitting parameters include the target pulse width, or include the target pulse width and target pulse strength, the target pulse width is the emitting time for emitting a single pulse light signal, and the target pulse strength is signal strength of the single emitted pulse light signal.

Description

technical field [0001] Embodiments of the present invention relate to the field of communication technologies, and in particular, to a method for controlling power consumption and a terminal device. Background technique [0002] At present, the time of flight (time of flight, TOF) technology is more and more widely used. For example, the terminal device may use the TOF module in the terminal device to perform three-dimensional (three dimensions, 3D) modeling, synthesize 3D images, distance detection or face recognition, and the like. [0003] Generally, when a terminal device uses a TOF module, it can send pulsed optical signals to the object under test at different time slots through the vertical cavity surface emitting laser (VCSEL) in the TOF module, and the terminal device can transmit pulsed optical signals according to the reflection of the object under test. The returned optical signal measures the depth of field information. Wherein, the pulse width of the pulsed o...
