Abstract: A detection control method and an apparatus are described that are used for target detection, and may be applied to the fields such as intelligent driving, intelligent transportation, surveying and mapping, and intelligent manufacturing. A control apparatus controls a laser emitting unit and a laser receiving unit to perform two phases of laser detection. A first phase of laser detection is used to determine a time location, and a second phase of laser detection is used for target detection in a time window including a first time location. In one aspect, in the second phase of detection process, the control apparatus controls a laser detection unit to receive an echo signal in a first time window. A time for receiving the echo signal is shortened, thus permitting an amount of data in the detection process to be reduced.
