Performance comparison between laser ranging sensor principle and ultrasonic ranging sensor

The laser range finder has a long measuring distance, high precision and low interference, which can be used for precise positioning. The laser range finder/ranging sensor is a sensor that uses a laser to accurately measure the distance of a target. The laser range finder emits a very fine laser beam to the target during operation. The photoelectric component receives the laser beam reflected by the target, and the timer measures the time from the transmission to the reception of the laser beam to calculate the distance from the observer to the target. The l

What are the characteristics of pulse laser range finder?

Pulse method (including time-of-flight method) emits a laser pulse from a laser generator and reflects it to the generator when it meets an object. The distance from the starting point to the target can be calculated by measuring the time interval between the laser emission time and the receiving time and dividing it by the beam. Characteristics of JRT Pulse Laser Range Finder: Convenience: Even in bad weather, there is no need for a reflector and it can be used

What are the characteristics of hand-held laser rangefinders?

Laser range finder is an instrument that uses laser to measure the distance of target accurately. The laser rangefinder emits a very fine laser beam to the target while it works. The laser beam reflected by the target is received by the photoelectric element. The time from the launch to the reception of the laser beam is measured by the timer, and the distance from the observer to the target is calculated. 1. The hand-held laser rangefinder generally refers to the laser measuring in the range of 0.05 M to 200 m.

Characteristics of Laser

1. Good coherence A tens of watt bulb can only be used for ordinary lighting. If its energy is concentrated in a sphere 1 m in diameter, a high optical power density can be obtained, and the steel plate can be pierced with this energy. However, ordinary light sources emit light in all directions, and the light energy can not be highly concentrated. The light emitted from different points on a common light source is chaotic in different directions and at different times, and it is impossible to gather at one p

Advantages and Inventions of Laser Range Finder Measurement-General Knowledge of Optical Instruments

Laser range finder measurement method has the following advantages. 1. There is no blind area based on the energy emitted to the object. 2. There are no restrictions on the surface properties (color, texture and texture). 3. Absolute measurements can be made directly. 4. Easy measurement In 1969, Hildebrand and Haines proposed a new method based on coherent optics. Full information contour technology using dual wavelength light source is introduced. It can generate contours on objects. The resolution of the contour dep

How to measure the practicability and reliability of lidar for robots?

As a lidar mainly used to measure distance, the maximum distance measured by lidar is naturally its core index. Most lidars take the measurement distance as their main index directly. However, in addition to the range, other indicators need to be taken into account: 1. Scanning frequency. 2. Measurement accuracy. 3. Ranging sampling rate. Higher scanning

IP Classification of Sensors

IP stands for ingress protection, indicating the degree to which an instrument can prevent impurities from intruding in different levels. The IP grade system developed by the International Electrotechnical Commission (IEC) incorporates IEC529 to provide guidance on the protection of instruments. It also provides more information for reference when purchasing instruments to ensure that a test instrument can work normally within the calibration range. IP level will appear in almost all product files.

Application of Laser Ranging Sensor in Automatic Pedestrian Avoidance System

Previously, several media reported that Nissan Automobile Company had successfully developed an automatic pedestrian avoidance system. The system consists of a camera and five laser ranging sensors. It can sense obstacles within 20 meters on both sides of the car, 150 meters in front of the car and 70 meters behind the car. Once pedestrians suddenly appear in front of the car, the system automatically controls the steering wheel and takes evasive action. It can not only avoid pedestrians, but also avoid collision with other vehicles. At pre

Influencing Factors Of Selecting And Purchasing Lidar

Lidar, as the standard of positioning and navigation for robots, plays an important role in helping robots to walk independently. As a sensor mainly used for laser ranging, the data of measuring distance, scanning frequency, angular resolution and measuring accuracy must be an important index for most people to measure, but in addition, there are many other indicators. Two very important but seldom noticed indicators are also important factors to consider when choosing products. 1. Detection rate of dark objects

Laser Ranging Sensor Based on TOF Algorithms

TOF is short for Time of Flight. Its measuring principle is to use the sensor to send laser photons to the target continuously, and then use the sensor to receive photons returned from the object, calculate the round-trip time and get the measured distance. With people's familiarity with light, optical ranging has gradually begun to occupy the sensing market. Laser ranging is one of the main development directions. Compared with infrared and ultrasound, laser ranging has advantages on the one hand. Because TOF ca
