LiDAR is a sensor that uses lasers to achieve precise ranging. In a broad sense, it can be regarded as a camera with 3D depth information and is known as the “eyes of a robot”. Since its birth, the LiDAR industry has been closely keeping in step with the cutting-edge development of underlying devices and […]
According to reports, the competition between LIDAR and other sensor technologies (camera, radar, and ultrasonic) has increased the demand for sensor fusion, and also requires careful selection of photodetectors, light sources, and MEMS micromirrors. LIDAR and other sensor technologies With the advancement of sensor technology, imaging technology, radar, LIDAR, electronic equipment and artificial intelligence technology, dozens […]
Without human operating, driverless vehicles perceive the environment through autonomous vehicle sensors, which are like the eyes of a vehicle. Collecting basic information about the surrounding environment through the environmental perception of sensors is the basis of autonomous driving. There are many types of autonomous vehicle sensors, such as cameras, millimeter-wave radars, and LiDARs. Camera: Camera can […]
LIDAR is mainly divided into: mechanical LiDAR, solid-state LiDAR, MEMS LiDAR, Flash area array LiDAR, OPA solid-state LiDAR, hybrid solid-state LIDAR…How much do you know about so many kinds of LIDAR? LiDAR LiDAR is a radar system that detects the position and velocity of a target by emitting laser beams. The laser band is located at 0.5μm-10μm, […]
According to the survey, most companies currently focus on the field of unmanned vehicles, robots, and unmanned vehicle LIDAR as their main research directions. The traditional mechanical LIDAR has gradually changed to solid state LIDAR. In the future, solid-state, small, low-cost LIDAR will be the focus of all enterprises. solid state LIDAR applications With the in-depth study of LIDAR technology by […]
Point Clouds come with all sorts of shape and form, each with distinct pros and cons. Over the years I have used point clouds from camera (SFM, photogrammetry), super dense and noisy, from medical device, with nice volumetric quality, and of course from Lidar. Now even Lidar points clouds can be very different depending on […]
Solid-state LiDAR Introduction The so-called solid-state LiDAR, it is generally recognized that the solid-state LiDAR is non-rotating. Usually, it’s divided into three types, based on phased array, Flash, and MEMS. The phased array principle is adopted to realize the solid-state LiDAR, which completely eliminates the mechanical structure, and changes the exit angle of the laser by adjusting the phase […]
LiDAR-based measurement principle introduction: LiDAR-based Measurement System uses high-definition solid-state video LiDAR to measure the empty truck body and loaded truck body, to obtain 3D imaging of the surface of the empty truck and the surface of the loaded truck with cargo. Through the camera image data, the artificial intelligence (AI) method is used to […]
Compared with ordinary microwave radar, the operating frequency of LiDAR is much higher than that of microwave radar because LiDAR uses a laser beam.LiDAR has many characteristics including: (1) High resolutionLidar sensor can obtain extremely high angle, distance and speed resolution. Usually the angular resolution is not less than 0.1mard, that is to say, it […]
LiDAR, which stands for Light Detection and Ranging, is a sensing technology akin to RADAR. But, while radar detects objects by the reflection of radio waves off their surface, LiDAR illuminates them with a laser beam and detects the bounce-back of the laser signal. LiDAR uses infrared LED or laser light to deliver light pause […]
