Detailed Description
Embodiments of a snow quantity judging platform and method using a moving carrier according to the present invention will be described in detail with reference to the accompanying drawings.
Visual inspection is to use a robot to replace human eyes for measurement and judgment. The visual detection means that a machine vision product (namely an image shooting device which is divided into a CMOS (complementary metal oxide semiconductor) product and a CCD (charge coupled device) product) converts a shot target into an image signal, transmits the image signal to a special image processing system, and converts the image signal into a digital signal according to information such as pixel distribution, brightness, color and the like; the image system performs various calculations on these signals to extract the features of the target, and then controls the operation of the on-site equipment according to the result of the discrimination. Is a valuable mechanism for production, assembly or packaging. It has immeasurable value in terms of the ability to detect defects and prevent defective products from being distributed to consumers.
Visual inspection involves taking an image of an object, inspecting it and converting it into data for processing and analysis by the system, ensuring compliance with its manufacturer's quality standards. Objects that do not meet the quality criteria are tracked and rejected.
The camera captures an electronic image of the inspected object which is then sent to a processor for analysis. The electronic image is converted to a number representing the smallest part of the image, i.e. the pixel. The number of pixels of the image displayed is called the resolution. The higher the resolution of the image is, the more the number of pixels is included, and when the detection is performed, the more the number of pixels of the image is, the more accurate the detection result is.

In addition, frequency division duplex means that uplink and downlink transmissions are performed on different frequencies. In the first and second generation cellular systems, FDD technology is basically used for duplex transmission. In particular, in the first generation cellular systems, since continuous baseband signals are transmitted, duplex uplink and downlink channels must be provided using different frequencies. In the first generation cellular systems, in which FDD is used for continuous information transmission, frequency synthesizers for generating different carrier frequencies are required at both the transmitting and receiving ends, and a duplex filter for preventing the transmission signal from leaking to the receiver is required at the receiving end. In addition, in order to facilitate the fabrication of the duplexer, a certain frequency interval is required between the transmission and reception carrier frequencies. In the second generation of systems such as GSM, IS-136 and IS-95, FDD technology IS also used. In these systems, since the information is transmitted in time slots, the transmission and reception can be performed in different time slots, and the transmission signal of the mobile station or the base station does not interfere with the receiver. So, despite the FDD technique employed, no expensive duplex filters are required.
The FDD mode is characterized by receiving and transmitting in two symmetric frequency channels separated (190 MHz between uplink and downlink frequencies), and separating the receiving and transmitting channels by guard bands.
By adopting the technologies of packet switching and the like, the bottleneck of the second generation development can be broken through, the high-speed data service can be realized, the frequency spectrum utilization rate can be improved, and the system capacity can be increased. FDD must provide third generation services using paired frequencies, i.e., within a bandwidth of every 2x5 MHz. The mode can fully utilize the uplink and downlink frequency spectrums when supporting the symmetric service, but the frequency spectrum utilization rate is greatly reduced (about 40 percent of the frequency spectrum utilization rate is reduced due to low uplink load) when the asymmetric packet switching (Internet) works, and in this regard, the TDD mode has incomparable advantages compared with the FDD mode.
