Abstract: This application relates to the field of radar technologies, and in particular, to a laser radar and an intelligent sensing device. The laser radar includes a radar body, a laser emitter board, a laser receiver board, and a counterweight structure. The laser emitter board and the laser receiver board are separately disposed on the laser body. The laser emitter board is configured to emit an emergent laser toward a detection target. The laser receiver board is configured to receive a reflected laser reflected by the detection target, and convert an optical signal into an electrical signal, so as to analyze a position, a three-dimensional image, a speed, and the like of the detection target. The radar body is connected to a power apparatus, and the power apparatus drives the entire radar body and the laser emitter board and the laser receiver board that are located on the radar body to rotate, so that the laser radar can detect a range of 360° around. In the present disclosure, the counterweight structure is disposed on the radar body, so that the radar body rotates more stably, thereby effectively ensuring precision of the radar and extending a service life of the radar.

Abstract: The present disclosure provides, for example, a lidar ranging method. The method may include calling a sequencer to generate a preset sequence with the sequencer. The method may also include determining a pulse transmission interval of double pulses according to the preset sequence and a preset value. The method may further include transmitting a probing signal to an object to be ranged according to the pulse transmission interval of the double pulses. The method may additionally include receiving, from the object to be ranged, an echo signal returned according to the probing signal. The method may also include extracting a valid echo signal from the echo signal. The method may further include calculating a distance from the object to be ranged according to a time difference between the valid echo signal and the probing signal.

Abstract: The present application pertains to the field of radar systems technology and provides a method, device, terminal device, and storage medium for determining the reflectance of a target object. The method involves obtaining the emission parameters of a detection signal emitted by a radar and the echo data of the echo signal and determining a correction coefficient based on the emission parameters or the echo data. The correction coefficient is related to the transmittance of the material through which the detection signal passes and is used to correct the reflectance of the object. The reflectance of the object is calculated based on the correction coefficient and the echo data.

Abstract: The present disclosure provides a LiDAR device and its ranging adjustment method. The ranging adjustment method involves first calibrating the echo intensities at different pixel positions in receiving units of the LiDAR device and then determining the corresponding correction coefficients. Based on these correction coefficients, the method corrects the intensity data output by the pixels at different positions, ensuring consistency in the intensity data output by the corresponding pixels of the same receiving unit.
