Method and device for controlling laser emission, and related apparatus

A device for controlling laser emission, comprising:

• a secondary emitting module, configured to emit a secondary emergent laser at a first time of a detection period;
• and
• a primary emitting module, configured to adjust a primary emergent laser emitted at a second time of the detection period according to a first detection echo corresponding to the secondary emergent laser,
• wherein a time interval between the first time and the second time is greater than or equal to a traveling time of a longest detection distance corresponding to the secondary emergent laser.

A method for controlling laser emission, comprising:

• emitting a secondary emergent laser in a secondary analysis region of a current detection period;
• determining whether a detection result of the secondary analysis region includes a target;
• and
• in response to determining that the detection result of the secondary analysis region includes the target, adjusting a primary emergent laser in a primary analysis region to be an adjusted power, the adjusted power being less than a preset power,
• in response to determining that the detection result does not include the target, further determining whether a detection result of the secondary analysis region of at least one previous detection period includes the target;
• in response to determining that the detection result of the at least one previous detection period does not include the target, emitting the primary emergent laser with the preset power in the primary analysis region;
• and
• in response to determining that the detection result of the at least one previous detection period includes the target, adjusting the primary emergent laser in the primary analysis region to the adjusted power.
