A kind of three-dimensional information acquisition device based on line laser and binocular vision, including binocular camera, optical filter, line laser transmitter, equipment load carrier, visual pattern processing mechanism and connecting line, binocular camera, line laser transmitter are mounted on equipment load carrier, optical filter is mounted on the outside of binocular camera camera lens, and equipment load carrier is connected with visual pattern processing mechanism by connecting line.Line laser transmitter is for projecting line laser to target object surface, binocular camera is used to acquire the image of line laser, visual pattern processing mechanism is used to handle and obtain target object three-dimensional information to the laser image analysis of acquisition, and optical filter is for being obtained by filtration figure line information corresponding with laser rays wavelength.The utility model overcomes the problem that binocular vision technology is very weak for no texture or texture, obscurity boundary object identification rate is not high, while reducing visual pattern processing workload, and then can accurately and rapidly obtain the three-dimensional information of target object.
Description
Technical field
The utility model relates to technical field of machine vision, in particular to a kind of three-dimensional based on line laser and binocular vision
Information acquisition device.
Background technique
Binocular vision is an important branch of computer vision, and binocular vision can be with apish eyes and human stereoscopic
The process of visual perception is one of core subject of computer vision research.In recent years, binocular vision technology is in obstacle quality testing
The fields such as survey, target object detection are widely used.
Currently, binocular vision detection is mainly the visual pattern for passing through binocular camera photographed scene, then to visual pattern
It is analyzed and processed, but the object of obscurity boundary very weak for no texture or texture, the accuracy rate for analyzing processing is not high,
In addition visual pattern analysis process data treating capacity is big, treatment effeciency is low, and mesh can not reliablely and stablely be obtained by eventually leading to
Target three-dimensional information.
Summary of the invention
In view of the above-mentioned problems, obtaining dress based on line laser and the three-dimensional information of binocular vision the utility model proposes a kind of
It sets, can rapidly and accurately obtain the three-dimensional information of target.
The technology employed by the present utility model is
A kind of three-dimensional information acquisition device based on line laser and binocular vision, including binocular camera, optical filter, line swash
Optical transmitting set, equipment load carrier, visual pattern processing mechanism and connecting line.Wherein, binocular camera, line laser transmitter peace
On equipment load carrier, optical filter is mounted on the outside of binocular camera camera lens, and equipment load carrier and visual pattern are handled
Mechanism is connected by connecting line.Line laser transmitter is for projecting line laser to target object surface, and binocular camera is for adopting
Collect the image of line laser, visual pattern processing mechanism is used to handle the laser image analysis of acquisition and obtains target object three-dimensional
Information, optical filter is for being obtained by filtration figure line information corresponding with laser rays wavelength.
In a kind of above-mentioned three-dimensional information acquisition device based on line laser and binocular vision, line laser transmitter in addition to
Be placed in equipment load carrier, outer can also be hung on equipment load carrier or with equipment load carrier partial installation.
In a kind of above-mentioned three-dimensional information acquisition device based on line laser and binocular vision, equipment load carrier and view
It, can also directly integral type installation other than feeling that image procossing mechanism is connected except through connecting line.
The utility model has the beneficial effects that: line laser is effectively combined with binocular vision, binocular vision is overcome
The problem that feel technology is very weak for no texture or texture, obscurity boundary object identification rate is not high, while reducing vision figure
As processing workload, and then it can accurately and rapidly obtain the three-dimensional information of target object.
Detailed description of the invention
FIG. 1 is a schematic structural view of the utility model；
Fig. 2 is the utility model usage scenario schematic diagram；
In figure: 1. binocular cameras；2. optical filter；3. line laser transmitter；4. equipment load carrier；5. visual pattern
Processing mechanism；6. connecting line；7. laser rays；8. examined object；9. conveyer belt.
Specific embodiment
The utility model is described in detail combined with specific embodiments below.
It is filled as shown in Figure 1 for a kind of obtained based on line laser and the three-dimensional information of binocular vision disclosed by the utility model
It sets, including binocular camera 1, optical filter 2, line laser transmitter 3, equipment load carrier 4, visual pattern processing mechanism 5 and company
Wiring 6.Wherein, binocular camera 1, line laser transmitter 3 are mounted on equipment load carrier 4, and optical filter 2 is mounted on binocular and takes the photograph
As on the outside of head mirror head, equipment load carrier 4 is connected with visual pattern processing mechanism 5 by connecting line 6.
A kind of three-dimensional information acquisition device based on line laser and binocular vision for being illustrated in figure 2 the utility model is used for
Detect use example when object dimensional information on conveyer belt.Conveyer belt 9 drives examined object 8 to pass through line laser transmitter 3
When the laser rays 7 launched, body surface leaves laser rays identical with profile, binocular camera under the filtering of optical filter,
Accurate intake laser rays, and the laser rays information of intake is transferred to visual pattern processing mechanism by connecting line.When to be detected
When object passes through laser rays completely, visual pattern processing mechanism can obtain the integrity profile laser rays group of examined object, pass through
Analysis handles the three-dimensional information that examined object can be obtained.
The foregoing is only a preferred embodiment of the present invention, but protection scope of the present invention it is not limited to this, appoint
What those familiar with the art within the technical scope of the present disclosure, according to the technique and scheme of the present invention and its sends out
Bright design is subject to equivalent replacement, change, material replacement, improvement etc., should be covered by the protection scope of the present invention.
