Image, vision, technology_image vision measurement technology classification
Vision measurement belongs to the category of computer vision. It is one of the specific application fields of computer vision. It is the introduction of computer vision into industrial inspection to achieve accurate measurement of the geometric size, position or shape of objects. It is the most accurate measurement field. A new technology with development potential is based on modern optics, combining computer technology and laser technology. Image processing and analysis technology and other modern science and technology integration of optical, mechanical and electrical integration comprehensive test system. Classification of vision measurement technology The size of the object to be measured by the scene (1) According to the size of the object to be measured, it can be divided into close-up measurement and microscopic measurement. Among them, it is tens of centimeters to tens of meters, and microscopic measurement mostly refers to the use of a microscope to test objects with dimensions below the order of millimeters. (2) According to whether the system moves during the measurement process, it can be divided into fixed measurement and mobile measurement. (3) According to the lighting method of the measurement process, it can be divided into vivid measurement and passive measurement. (4) According to whether the scene in the processed image is moving, it can be divided into static image measurement and dynamic image measurement. (According to the number of camera wingmen used in the measurement system, it can be divided into monocular vision measurement, binocular vision measurement and multi-eye vision measurement. There are many classification methods for vision measurement, and the commonly used classification methods are as follows.
Hydraulic universal testing machines have very high accuracy requirements.
The hydraulic system is the power drive mechanism of the tensile testing machine.
The specific application of the electronic universal testing machine in the automobile manufacturing process: The electronic universal testing machine needs to be used for automobile parts.
Wave soldering refers to the molten solder (lead-tin alloy), sprayed by electric pump or electromagnetic pump into the solder wave required by the design, can also be formed by injecting nitrogen into the solder pool, so that it is pre-loaded The printed board of the component realizes the soft soldering of the mechanical and electrical connection between the solder end or the pin of the component and the pad of the printed board through the solder wave.
The frequency converter is a power control equipment that uses frequency conversion technology and microelectronics technology to control AC motors by changing the frequency of the motor's working power supply.
Electronic universal testing machine is a necessary equipment to control the quality of products.
The calibration operation of the electronic universal testing machine is still relatively unfamiliar to friends who use it for the first time.
Selective wave soldering defects and their prevention.
Testing machine, broadly speaking, is an instrument that verifies the quality or performance of a product or material according to the design requirements before it is put into use.
The tensile force is not an accurate value after being measured by the testing machine, and subsequent calculations are required to get the desired value.
