Description: 超声波测距仪的设计 电子测距仪要求测量范围在0.10～5.00m，测量精度1cm，测量时与被测物体无直接接触，能够清晰稳定地显示测量结果。由于超声波指向性强，能量消耗缓慢，在介质中传播的距离较远，因而超声波经常用于距离的测量，如测距仪和物位测量仪等都可以通过超声波来实现。-Ultrasonic range finder range finder design requirements of the electronic measurement of the range of 0.10 ~ 5.00m, measurement accuracy 1cm, measured with the measured object without direct contact, being able to clearly demonstrate the stability of the measurement results. Strong point as a result of ultrasonic energy consumption slow, in the medium distance transmission, which are often used for ultrasonic distance measurement, such as range finders and all level measurement can be achieved through ultrasound.

Description: The report details the implementation of distance measurement system using the
ultrasonic waves. As the human ear’s audible perception range is 20 Hz to 20 kHz, it is
insensitive to ultrasonic waves, and hence the ultrasound waves can be used for applications in
industries/vehicles without hindering human activity. They are widely used as range meters and
proximity detectors in industries also it can be used in parking assistance system. The distance
can be measured using pulse echo and phase measurement method. Here the pulse echo method
is used. The measurement unit uses a continuous signal in the transmission frequency range of
ultrasonic transducers. The signal is transmitted by an ultrasonic transducer, reflected by an
obstacle and received by another transducer where the signal is detected. The time delay of the
transmitted and the received signal corresponds to the distance between the system and the
obstacle. Platform: |

Description: 激光雷达数据处理，辨别有毒云，校正因为激光雷达数据扫描时造成的极坐标几何扭曲-In this particular application, scanning Lidar equipment is used to
detect cross sections of clouds or plumes. The same scan geometry,
however, is used in medical ultrasound and other types of imaging.
The Lidar principle uses a laser beam to detect atmospheric reflection
intensity at various range resolved distances along the beam axis.
Each such measurement is a line scan (intensity versus distance).
The beam is swept up and down using a mechanical linkage driven by a
motor at constant speed. At equal time intervals, successive scan
lines are recorded. Harmonic motion of the beam rocking linkage
results in approximately sinusoidal scan angles with time.
A set of successive scan lines forms an acquired image. Images record
reflected intensity as a function of radial distance and sweep angle.
Hence, scan images are acquired in polar (curvelinear) space with
nonuniform spacing.
In this case the goal of image processing is to analyze the size and
location of Platform: |
