摘要：
A laser distance measurement method is provided in which a laser light L is irradiated while scanning in a horizontal direction and in a vertical direction of a monitoring range S, reflected light R of the laser light L is received and received light information d6 is obtained, and distance information d7 of a target object M in the monitoring range S is calculated from the received light information d6, in which, if a plurality of pieces of the reflected light R1 to Rn are received from the same laser light L and if the number of pieces of the reflected light R1 to Rn is less than a reference value N, the reflected light R received last is considered to be the reflected light R from the target object M and the distance information d7 is calculated, while if the number of pieces of the reflected light R1 to Rn is not less than the reference value N, the reflected light R received at the N-th time is considered to be the reflected light R from the target object M, and the distance information d7 is calculated.
摘要（中）：
提供一种激光距离测量方法，其中在水平方向和监视范围S的垂直方向上扫描激光L，并且获得激光L的反射光R并接收光信息d6， 并且从接收到的光信息d6计算监视范围S中的目标对象M的距离信息d7，其中如果从相同激光L接收到多条反射光R1至Rn，并且如果数目 反射光R1至Rn的片数小于参考值N，则最后接收的反射光R被认为是来自目标对象M的反射光R，并且计算距离信息d7，而如果数量 反射光R1至Rn的值不小于基准值N，则在第N次接收的反射光R被认为是来自目标物体M的反射光R，距离信息 计数d7。
