rpvision 2.0 high-speed vision ranging engine
RPLIDAR A2 uses laser triangulation technology, coupled with the independent research and development of the RPVision2.0 high-speed vision ranging engine, can be up to 4,000 times per second ranging action, and in the long-distance work also excellent performance.
Robot synchronization location and map construction (SLAM)
RPLIDAR is the most ideal sensor for the application of Slam algorithm, which has the characteristics of high precision and high performance.
environmental scanning and 3D reconstruction
By emitting a laser to scan the analyte, directly obtain high-precision scanning point cloud data, can obtain the measured object surface three-dimensional coordinates, the real world to effectively three-dimensional modeling and virtual reproduction.
obstacle detection and avoidance of security
By using LIDAR data fusion, obstacle detection can be accomplished, and with vision technology, LIDAR can locate intruders, track and control, and provide more economical and reliable security solutions.
multi-touch and human-computer interaction
Compared to traditional technology, the use of infrared laser equipment can achieve large-screen multi-touch, faster response, higher accuracy, anti-ambient light capability.
supporting robot autonomous positioning and navigation solutions
RPLIDAR A2 as the core sensor, can quickly obtain environmental contour information, with the use of the Slamware technology, can help the robot to build maps, real-time path planning and automatically avoid obstacles.
2, slamtec-technology RPLIDAR-A1 LiDAR Price: 1053 yuan/Set
RPLIDAR A1 Laser Radar uses laser triangulation technology, with independent research and development of high-speed vision acquisition and processing mechanism, can carry out more than 2000 times per second ranging action. degree scanning, 5.5 Hz adaptive Scanning frequency, 2000 times per second of laser ranging, no less than 6m ranging range, measuring the resolution of the range 0.1%.
second, the import of laser radar price
1, velodynehdl-64e lidar Price: 115000 yuan/Taiwan (equivalent to RMB: 782000 yuan/set)

Compared with foreign countries, there is a big gap in multi-line lidar, but the LiDAR used in service robots and sweeping robots is not very different. Domestic laser radar products are used in service robots, topographic mapping, building surveying and other fields, has not yet developed for Adas and unmanned system of 3D LiDAR products. However, with the wave of smart cars from abroad to the domestic, to think haze, radium God, Superstar and so on behalf of a number of domestic enterprises have also begun to try to enter the automotive laser radar this new industry.
