Operation method of three-dimensional substance surface scanning device based on intelligent sensing

Abstract

The invention provides an operation method of a three-dimensional substance surface scanning device based on intelligent sensing in order to solve the technical problems that due to the fact that scanning equipment is unsteady and a scanning device is inaccurate in focusing in the scanning process of substances such as logs, a captured graph is large in error and not clear. The operation method comprises the steps that the positions of two carrying frames on a containing slide rail and the distance between the carrying frames are adjusted according to the length of an measured object; a lifting instruction is sent to a transmission lifting rail through a computer to adjust the position of a lifting frame; graph data information is acquired in real time, image restoration is conducted on the computer, and restored image information is stored. The operation method has the advantages that the high-definition three-dimensional image of the measured object such as the logs can be accurately restored in the computer, the signal collecting speed is increased, the signal collecting stability is improved, and the three-dimensional substance scanning precision and efficiency are improved.

Description

technical field [0001] The invention relates to the technical field of track transmission of scanners, in particular to a three-dimensional scanning device for a material surface based on intelligent sensing, and to an operation method for the three-dimensional scanning device for a material surface. Background technique [0002] Most of the forest plants represented by trees need to grow for a long period of time before they can reach a diameter suitable for human use; in addition, they are affected by climatic conditions, weather changes, human disturbance, animals and microorganisms during their growth, resulting in their The degree of sharpness, curvature, cracking, knots, decay, etc. are different; since forest resources are an important resource closely related to human production and life, how to be reasonable and effective in building a resource-saving and environment-friendly society today? Utilization of forest resources is an important topic worth pondering; if th...

[0003] In order to obtain the basic parameters of the log outer contour, people have generally adopted a measurement method combining visual observation and mechanical measurement. Because this method relies too much on the experience of the operator and has large measurement errors, the sharpness, curvature and internal Defects and other information are not easy to obtain, so the measurement results are not satisfactory; with the advancement of measurement technology, people began to use acoustic, optical, thermal and electromagnetic methods to conduct non-contact measurement research on the outer contour of objects, but due to wood Due to heterogeneity, porosity and anisotropy, these measurement methods are not completely suitable for the measurement of logs; how to analyze and select the shape, size and various defects of the outer contour of logs has become a key issue in the field of wood processing. At the same time, the rapid development of information and Internet technology has brought the rapid arrival of the era of the Internet of Things, prompting the wood processing industry to advance in the direction of "optical-mechanical-electrical integration". How to capture high-precision log parameters and realize computer-to-computer The automatic analysis of log parameters and the output of measurement results to the manufacturing system are important issues that need to be solved in the current wood processing industry

[0004] Using laser to measure distance in a non-contact manner has the advantages of simple structure, fast test speed, strong real-time processing capability, and high precision. The efficiency is not high and the overall precision of the instrument is low and the accuracy is poor. At the same time, it will also cause the scanning device to be unstable during the scanning process, making the captured graphic error larger and blurred. Therefore, the laser ranging method in the prior art cannot Applied directly to the outer contour measurement of logs and other measured objects
