In the control method of the time of flight (Time of flight, TOF) module of the present application, the time of flight module includes an optical transmitter and an optical receiver, and the control method includes: the optical transmitter emits a laser; the optical receiver obtains a laser infrared image; when When the number of frames of the laser infrared image is greater than or equal to two frames, calculate the light intensity difference between two adjacent frames of the laser infrared image and define the light intensity difference as the first light intensity difference; and, when the first light intensity difference is greater than the preset threshold, the light emitter turns off. The control method determines that the light transmitter is abnormal or damaged when the first light intensity difference is greater than a preset threshold, so that the time-of-flight module can detect whether the light transmitter is damaged without installing additional devices, so that the time-of-flight module The structure is simple and the manufacturing cost is low. The light emitter is turned off when the first light intensity difference is greater than the preset threshold, so as to prevent the light emitter from emitting excessively strong laser light and burning the user when the light emitter is abnormal or damaged. The present application also discloses computer-readable storage media, electronic devices, and time-of-flight components.
Description
technical field [0001] The invention relates to consumer electronics technology, in particular to a control method of a time-of-flight module, a time-of-flight component, an electronic device and a computer-readable storage medium. Background technique [0002] The time of flight (TOF) module includes an optical transmitter and an optical receiver. When the optical transmitter works abnormally, the laser emitted by the optical transmitter may easily burn the user. The existing optical transmitter generally detects whether the optical transmitter is damaged or abnormal by setting an additional device, which leads to a more complex structure of the time-of-flight module and increases the cost of the time-of-flight module. Contents of the invention [0003] Embodiments of the present invention provide a time-of-flight module control method, a time-of-flight component, an electronic device, and a computer-readable storage medium. [0004] The control method of the time-of-fli...
