摘要： The present disclosure discloses a method and system for identifying a part of a vehicle and a vehicle inspection system. The method includes: acquiring (S110) a vehicle body image sequence of a vehicle to be identified; reconstructing (S120) the vehicle body by using a first vehicle body reconstruction model generated through a deep learning algorithm and on the basis of the vehicle body image sequence, so as to acquire a vehicle body reconstruction image of the vehicle to be identified; and identifying (S130) a boundary identifier of the vehicle to be identified on the basis of the vehicle body reconstruction image of the vehicle to be identified.

摘要： A vehicle type recognition method based on a laser scanner is provided in this invention, the method comprising steps of: detecting that a vehicle to be checked has entered into a recognition area; causing a laser scanner to move relative to the vehicle to be checked; scanning the vehicle to be checked using the laser scanner on a basis of columns, and storing and splicing data of each column obtained by scanning to form a three-dimensional image of the vehicle to be checked, wherein a lateral width value is specified for each single column of data; specifying a height difference threshold; and determining a height difference between the height at the lowest position of the vehicle to be checked in data of column N and the height at the lowest position of the vehicle to be checked in data of specified number of columns preceding and/or succeeding to the column N, if the absolute value of the height difference is larger than the specified height difference threshold, labeling a position of the vehicle to be checked corresponding to the data of the column N as a start position of a gap portion of the vehicle to be checked, a length corresponding to data of the first N columns being the length of the head portion of the vehicle to be checked in the three-dimension image. A fast vehicle type recognition system using the same method is also provided in this invention.

摘要翻译： 本发明提供了一种基于激光扫描仪的车辆识别方法，该方法包括以下步骤：检测待检查车辆已经进入识别区域; 使激光扫描仪相对于要检查的车辆移动; 使用激光扫描仪基于列扫描要检查的车辆，并且存储并拼接通过扫描获得的每列的数据，以形成要检查的车辆的三维图像，其中为每一个指定横向宽度值 单列数据; 指定高度差阈值; 并且确定在列N的数据中要检查的车辆的最低位置处的高度与要检查的车辆的最低位置处的高度之间的高度差，该数据在指定的列数之前和/或之后的数据中 列N，如果高度差的绝对值大于指定的高度差阈值，则将与列N的数据对应的待检查车辆的位置标记为车辆的间隙部分的开始位置 检查，与三维图像中要检查的车辆的头部的长度相对应的前N列的数据的长度。 本发明还提供了使用相同方法的快车型识别系统。
