The purpose of this paper is the design of target recognition system based on machine vision. Through the needs analysis of the system, hardware platform and software platform is built on machine vision. The scheme of machine vision based on PXI bus is put forwarded. The VISION module which is the machine vision of Lab VIEW software is introduced. The target (star) of the image acquisition and target...
The objective of this work is the design of virtual instrument software system based on state machine. Through the introduction of the basic principles of it, state machine described in detail the working mechanism and its implementation in LabVIEW, combined with the a test system. With the development of practice, for the multi-state system, the nested state machine design-type thinking. Practice...
In this paper, a dual-channel pseudorandom sequence generator is presented for the calibration of cross correlators in flow metering. In the sequence generator, the two channels have completely identical hardware structures so that they generate two identical sequences of pseudorandom signals to simulate two signals obtained from the upstream and downstream sensors of a cross correlator, respectively...
