specific Embodiment approach 1

[0024] Specific Embodiment 1: Combining figure 1 and figure 2 Describe this embodiment mode, a log laser three-dimensional scanning track transmission device described in this embodiment mode, has a transmission slide rail 1, a bracket 2 and a laser scanning device 3, and is characterized in that the bracket 2 is installed on the transmission slide rail 1 , the laser scanning device 3 is installed on the support 2, the transmission slide rails 1 are arranged in parallel, and there are two parallel slider plates 21 at the bottom of the support 2, and the slider plates 21 are connected to the The transmission slide rail 1 is connected, and the bracket 2 slides or is fixed on the transmission slide rail 1.

[0025] The technical effect of this embodiment is: due to the two transmission slide rails arranged in parallel, the bracket can move smoothly, so that the laser signal emitted by the light source can be accurately detected by the detector after being irradiated on logs and...

specific Embodiment approach 2

[0026] Specific Embodiment 2: Combining figure 1 , figure 2 and image 3 Describe this embodiment, the log laser three-dimensional scanning track transmission device described in this embodiment, the transmission slide rail 1 is provided with a slide rail protrusion 11, and the bottom of the slider plate 21 has a slide rail concave 22, so The slider plate 21 is connected to the slide rail projection 11 on the transmission slide rail 1 through the slide rail concave 22 ; the others are the same as the specific embodiment 1.

[0027] The technical effect of this embodiment is: by setting upward slideway protrusions on the transmission slide rail and setting slide rail indentations at the bottom of the slider plate, the slider plate and the slideway can be closely connected, and it is not easy to be exposed to foreign substances such as dust. The impact of objects makes the movement of the bracket on the transmission track smoother, thereby ensuring the acquisition accuracy of...

specific Embodiment approach 3

[0028] Embodiment 3: Combining image 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 To illustrate this embodiment, the transmission slide rail 1 of this embodiment includes a first slide rail 12 and a second slide rail 13, and the slider plate 21 includes a first slider plate 211 corresponding to the first slide rail 12, and The second slider plate 212 corresponding to the second slide rail 13, the first slider plate 211 has a first frame body 23, the second slider plate 212 has a second frame body 24, and the first slider plate 212 has a second frame body 24. The first frame body 23 and the second frame body 24 are connected by a cross beam bar 25; the others are the same as the specific embodiment 1 or 2.

[0029] The technical effect of this embodiment is: the log to be measured usually has a longer length and a larger diameter, and the common bracket is not suitable for the measurement of the log. The relative position of the two brackets is fixed by a beam rod, ...

Abstract

The invention provides a log laser three-dimensional scanning track transmission device for solving the problem that scanning equipment are instable in the log scanning process so that the captured images are large in error and fuzzy. The device comprises transmission slide rails, a support and laser scanning equipment, wherein the support is installed on the transmission slide rails, the laser scanning equipment is installed on the support, the at least two transmission slide rails are arranged in parallel, at least two parallel slide block plates are arranged at the bottom of the support, the slide block plates are connected with the transmission slide rails, and the support sides or is fixed on the transmission slide rails. The device has the advantages that high-definition three-dimensional images of logs can be accurately reduced in a computer, the speed and the stability of signal acquisition are improved, logs can be processed with high precision, and optical-mechanical-electrical integration of the log processing industry is possible.

Description

technical field [0001] The invention relates to the technical field of track transmission of scanners, in particular to a log laser three-dimensional scanning track drive device. Background technique [0002] Trees need to grow for a long period of time before they can reach a diameter suitable for human use; in addition, trees are affected by climatic conditions, weather changes, human disturbance, animals and microorganisms during their growth, resulting in their sharpness, curvature, Cracks, knots, decay, etc. are different; since forest resources are an important resource that is closely related to human production and life, how to use forest resources reasonably and effectively is a worthwhile task in building a resource-saving and environment-friendly society An important topic for deep consideration; if the shape, size and various defects of the log outline can be analyzed and selected according to the specific conditions of each different log, it is possible to carry...
