    Benewake(www.benewake.com)is a national high-tech enterprise, with over 80 employees. The company is located in Keshi Building, Haidian district, Beijing. Benewake focuses on thesolid-state LiDAR.In 2016, the company received A+ round investment from Shunwei Capital, IDG Capital and Ecovacs. Benewake’s DE-LiDAR, a mass production level product, possess complete intellectual properties and recognition. The products have been launched in the American, European and Japanese market already. The Benewake products can be widely applied in the autonomous driving (obstacle avoidance navigation), the drones (plant protection in agriculture), robots (smart home), AGV (warehouse logistics in industry). In 2016, Benewake was awarded the champion of the Audi Innovation Lab. In 2017, Benewake has entered BOSCH Accelerator.

    1. Lidar Sensors For Drone Collision Avoidance

    Within a lidar sensor, a number of independent elements are integrated into a single device and will generate critical ranging data for safe navigation along with precise positioning. Lidar sensors have obstacle detection capabilities over a wide field of view which makes them ideal as part of a sense and avoid solution. Lidar is the leading technology for automobile collision avoidance and also in driver-less cars.


    2.Lidar Sensors For Ground And Above Ground Imagery
    The latest lidar sensors have integrated optical altimeter technology which deliver accurate distance measurements above ground level while meeting size, weight, and cost requirements of UAV manufacturers.

    Agriculture and forestry use lidar to inspect vegetation such as leaves and crops. Also, the above ground imagery (for example forest canopy) can be removed to view the ground surface area.

    3.Lidar Drones For Structural Inspection
    The best lidar sensors have powerful built-in signal processing, large field of view, and multi-segment measurements which generate critical distance data and efficient obstacle detection which enable safe navigation when performing structural inspections.


    4.Lidar Sensor At Night

    Lidar sensors also described as laser scanning will work in low contrast or shadowy situations, even at night.

    5.Multispectral and Photogrammetry Imagery
    Lidar, multispectral and photogrammetry imagery are all very closely related technologies. In some sectors and situations, images from all 3 are required to give a full analysis of the terrain, vegetation or structure.


    6.ToF 3D Cameras (Flash Lidar)
    Now, sometimes you might hear people talk about Flash Lidar. Time-of-Flight cameras sensors are often referred to as Flash Lidar. But there are big differences in the technology and its uses.

    ToF is scannerless, meaning that the entire scene is captured with a single light pulse, as opposed to point-by-point with a rotating laser beam.

    Time-of-flight cameras capture a whole scene in three dimensions with a dedicated image sensor, and therefore has no need for moving parts. ToF has so many great uses. Here is a terrific article giving you all the information on ToF cameras and best uses.
