Description

Technical Field

[0001] The patent of this invention relates to the field of binocular stereo vision technology, specifically an adjustable binocular stereo vision method and device. Background Art

[0002] Binocular stereo vision is an important form of machine vision. It is based on the principle of parallax and uses imaging equipment to obtain two images of the object being measured from different positions. By calculating the positional deviation between corresponding points in the images, the three-dimensional geometric information of the object is obtained. Existing binocular stereo vision equipment is used to measure the distance between objects.

[0003] However, the existing adjustable binocular stereo vision adaptation device has the following disadvantages:

[0004] The existing adjustable binocular stereo vision adapter device has a weak height adjustment function. When in use, the binocular stereo vision equipment is usually needed to be used outdoors to detect the distance between two objects and can be used to upload three-dimensional data. During time detection, the height of the device needs to be adjusted according to different environments for support. The existing technology cannot adjust the height of the bracket according to the environment. Summary of the Invention

[0005] The present invention aims to provide an adjustable binocular stereo vision method and device to address the problems raised in the above-mentioned background art. This device can be adjusted in height to facilitate adaptation to different detection environments, is easy to operate, and improves the practicality and flexibility of the binocular stereo vision system.

[0006] The technical solution for achieving the purpose of the present invention is:

[0007] An adjustable binocular stereo vision method and device, comprising

[0008] The top end of the telescopic rod is fixedly connected to the connecting plate, and the outer surface of the telescopic rod is connected to the connecting plate in sequence from the inside to the outside. The connecting rod can be movably extended into the inner cavity of the supporting column. The bottom surface of the fixing plate is provided with a threaded hole, the inner wall of the threaded hole is threadedly connected to the threaded rod, and the bottom end of the threaded rod is fixedly connected to the connecting rod. A clamping block is fixedly provided on the outer surface of the lower end of the connecting rod, and the inner wall of the support column is provided with a vertical slide groove and multiple groups of horizontal slots. The slide grooves are cross-staggered with each group of slots. The clamping block is engaged with the slot after sliding through the slide groove. The inner bottom wall of the support column is fixedly connected to the telescopic rod, and the top of the telescopic rod is fixedly connected to the connecting plate. The outer surface of the telescopic rod is sleeved with a spring, and the top end of the connecting plate is movably connected to the bottom end of the connecting rod.

[0009] On one side of the outer surface of the support column, a connection groove is provided, and a handle is fixedly connected to the inner wall of the connection groove; on one side of the machine body, an installation groove is provided, and a first eyepiece is fixedly connected to the inner wall of the installation groove; on the other side of the machine body, a circular slot is provided, and a second eyepiece is fixedly connected to the inner wall of the circular slot; at the contact part between the machine body and the second eyepiece, a thread ring surrounding the outer wall of the second eyepiece is provided, and a dust-proof cover is threadedly connected to the thread ring; in the middle of the top of the machine body, a placement groove is provided, and an image conversion camera is fixedly connected to the inner wall of the placement groove. The image conversion camera is connected to the second eyepiece and is externally connected to a mobile terminal at the same time.

[0010] The number of the clamping blocks is the same as the number of the sliding grooves.

[0011] The number of the first eyepieces is the same as that of the second eyepieces, and the axes of the first eyepieces and the second eyepieces on the same side are on the same axis.

[0012] Working principle:

[0013] When the spring is not compressed, the clamping block is clamped with the uppermost clamping groove in the support column. When it is necessary to adjust the height of the connecting rod and the support column, hold the handle of the support column by hand, push the support column to slide the clamping block of the connecting rod from the clamping groove to the sliding groove, so that the support column moves radially along the connecting rod. After reaching the height that needs to be adjusted, hold the handle of the support column by hand, push the support column to snap the clamping block of the connecting rod from the sliding groove into the clamping groove, then take out the dust-proof cover on the second eyepiece, and then the eyes of the staff can observe the object to be measured through the first eyepiece and the reflection of the second eyepiece, and then the data of the object is collected by the image conversion camera and transmitted to the mobile terminal.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] In the device of the technical solution, through the settings of the fixing plate, the threaded rod, the connecting rod, the clamping block, the clamping groove, the support column, the sliding groove, the telescopic rod, the connecting plate and the spring, when in use, the connecting rod is fixed at the bottom end of the fixing plate by rotating the threaded rod. Hold the handle of the support column by hand and push the support column, the clamping block of the connecting rod can be slid from the clamping groove into the sliding groove, and then hold the support column by hand and move it up and down to slide the clamping block from the sliding groove into the corresponding clamping groove. The connecting plate fixed by the telescopic rod abuts against the bottom end of the connecting rod, and when the connecting rod moves downward, the telescopic rod will be squeezed. When the spring on the outer surface of the telescopic rod is squeezed, it will contract, and after the clamping block is inserted into the clamping groove, the spring will abut against the connecting plate, and the connecting plate abuts against the connecting rod to firmly fix it in the clamping groove, so that the height of the rotating adjustment device can be achieved, which is convenient for adapting to different detection environments.
