Abstract: This application provides a parameter configuration method, device, and non-transitory computer-readable storage medium. In this method, the receiving units in the LiDAR receiving array are grouped according to a preset rule. Then, based on the detection requirements, the measurement range corresponding to each group of receiving units is set. Based on the measurement range of each group of receiving units, the storage space for each group of receiving units is set. The storage space is used to store the measurement data of each group of receiving units. Thus, the method reduces the acquisition of measurement data by some receiving units in unnecessary measurement ranges, decreases the volume of measurement data, and saves storage space.

Abstract: The embodiments of the present application disclose an emitter, an emitting module, and a LiDAR. The emitter includes a laser, a driving circuit, a substrate, and a heat conduction member. The laser and the driving circuit are both mounted on the substrate, and the heat conduction member is connected to the substrate, with at least the portion of the substrate used for mounting the laser being in contact with the heat conduction member. Mounting the laser on the substrate and having at least the portion of the substrate used for mounting the laser in contact with the heat conduction member facilitates timely and efficient heat dissipation from the laser through the heat conduction member, improving the heat dissipation rate around the laser and avoiding local hot spots at the laser, thereby ensuring the normal operation of the laser.
