The present disclosure provides a lidar system. The lidar system includes: an optical rotating mirror and at least two laser transceiving modules. Each laser transceiving module includes a transmitting unit and a receiving unit. The transmitting unit is configured to transmit a laser signal. The optical rotating mirror is configured to rotate around a rotating axis in a vertical direction, receive the laser signal and adjust a direction of the laser signal during rotation, and reflect the laser signal to a target object. The laser signal is diffusely reflected on the target object, which produces an echo signal. The echo signal is reflected by the optical rotating mirror and is then received by the receiving unit. The receiving unit includes a plurality of detectors arranged in an array.

Lidar system

An image fusion method based on image and LiDAR point cloud is provided. The method comprises: acquiring a first image and sparse point cloud data, point cloud data in each channel of the sparse point cloud data corresponding to pixels in the first image respectively, and the sparse point cloud data and the first image having space and time synchronicity; obtaining a target gradient value corresponding to at least one target pixel in the first image according to the first image, the target pixel being a non-edge pixel of the first image; up-sampling the sparse point cloud data based on at least one target gradient value to obtain dense point cloud data, the target gradient value being determined according to a corresponding target pixel between adjacent channels of the sparse point cloud data; and obtaining a target fusion image based on the first image and the dense point cloud data.

Methods, devices, apparatuses, and media for image fusion utilizing images and LiDAR point clouds

A method and a system for optically adjusting an image fusion LiDAR system are provided. The method includes: presetting initial positions of a first detector and a second detector; acquiring signal strengths of the echo signals emitted by diffuse reflection at different positions on a background wall detected by the first detector; determining a first mark position on the background wall according to the signal strengths of the echo signals; and adjusting at least one of a position or an attitude of the second detector according to an echo signal emitted by diffuse reflection at the first mark position, the first detector and the second detector being each a linear array detector.

Optical adjustment for image fusion LiDAR systems

The present disclosure provides a narrow-pulse-width pulse laser, including a circuit substrate, a laser chip, one or more capacitors, and a field effect transistor. Each of the field effect transistor, the capacitor, and the laser chip is electrically connected to the circuit substrate. The capacitors are arranged between the field effect transistor and the laser chip along an extension direction of a gap between the field effect transistor and the laser chip. The circuit substrate may include a first conductor layer; a second conductor layer; and an insulating layer arranged between the first conductor layer and the second conductor layer, wherein the first conductor layer and the second conductor layer are electrically connected through a via hole in the insulating layer.
