Abstract: A receiving optical system includes a receiving lens group and a detection module. The receiving module is configured to receive an echo signal obtained by reflecting signal light by a target in a detection region, and a horizontal focal plane and a vertical focal plane of the echo signal are separated. The detection module is configured to perform optical-electrical conversion on the echo signal in order to obtain an electrical signal used to determine association information (such as a distance, a speed, or a grayscale) of the target.

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.

Abstract: A detection system, a terminal device, and a detection control method are provided, to resolve a problem of low detection accuracy of a detection system in the conventional technology, and are used in fields such as autonomous driving, intelligent driving, assisted driving, or networked vehicles. The detection system includes a transmit module, a receive module, a first scanning module, and a second scanning module. An included angle between a first normal vector of a first reflective surface of the first scanning module and a second normal vector of a second reflective surface of the second scanning module is a first angle greater than 0 degrees. The first reflective surface and the second reflective surface are adjacent reflective surfaces. An included angle between an optical axis of the transmit module and an optical axis of the receive module is a second angle greater than 0 degrees.

Abstract: A detection apparatus includes a scanning system, the scanning system includes a micro reflector array, and the micro reflector array includes M micro reflectors. The detection apparatus further includes P transceiver modules. An optical signal sent by the P transceiver modules is reflected by the M micro reflectors, and/or the P transceiver modules receive an optical signal reflected by the M micro reflectors. The P transceiver modules do not need to receive and send signals using one micro reflector, but may receive and send signals by using the M micro reflectors.
