The invention discloses a laser radar identification system. The lidar identification system includes: millimeter wave radar, lidar, weather detector and data correction server, the millimeter wave mine and the lidar are respectively connected to the data correction server, the weather detector and the laser Radar connection; the present invention combines the millimeter-wave radar with the laser radar, and detects the weather information value through the weather detector, and judges whether the weather information value exceeds the weather information threshold. In the case where the weather information value exceeds the weather information threshold , the laser sensor that triggers the lidar automatically adjusts the laser beam volume according to preset rules, which can effectively reduce the probability that traditional radar and general lidar cannot recognize the vehicle type and the number of axles due to harsh environmental factors, or the identification is inaccurate. To achieve the purpose of accurately monitoring highway vehicles.
Description
technical field [0001] The invention relates to the technical field of intelligent transportation, in particular to a laser radar identification system. Background technique [0002] In recent years, the informatization and intelligence of expressways have become the focus of transportation construction and have attracted the attention of many enterprises. Radar is an important technology for human perception and detection of the world, and it is also an important means of monitoring high-speed vehicles in our country. Radar uses radio detection and ranging, which uses electromagnetic waves to detect targets, emits electromagnetic waves to irradiate the target and receives its echo, so that relevant information such as the distance from the electromagnetic wave to the target can be obtained. Radar technology not only has normal human visual recognition, but also has the ability of medium and long-distance environment perception. At present, radar technology mainly includes...
