Description
Technical field
It the utility model is related to machine vision high accuracy positioning detection field, and in particular to a kind of swashing based on machine vision
Light spot location instrument.
Background technology
Laser due to have the characteristics that directionality, monochromaticjty, coherence are good and brightness is high and be widely used in position with
The design of track system, in particular with the extensive use and development of embedded technology, laser positioning is realized using embedded technology.
At present, laser positioning is positioned by ranging, be exactly laser generator launch a laser signal, then according to receive from
The time difference for the signal that object reflects calculates fore-and-aft distance, then determines object and hair according to the angle of transmitting laser
The angle of emitter, so as to draw the relative position of object and transmitter.But can not to measure target same flat for this laser positioning
The lateral separation of off-center point on face, i.e., on X-Y plane from the origin of coordinates with a distance from, this lateral separation is in many applied fields
All there is very high practical value in scape.
Utility model content
In order to overcome shortcoming and deficiency existing for prior art, the utility model provides a kind of laser based on machine vision
Spot location instrument.
The utility model adopts the following technical scheme that：
A kind of laser spot locating instrument based on machine vision, including at laser generator, camera bellows, industrial camera, image
Reason device and host computer, the industrial camera are connected with image processor, and image processor is connected with host computer, the industrial camera
And image processor is arranged in camera bellows, the one side of the camera bellows is target surface, the target surface in industrial camera within sweep of the eye,
The laser generator launches laser on target surface, forms hot spot, and industrial camera obtains light spot image, and input picture processor obtains
To hot spot coordinate, it is then input in host computer.
The target surface is baking vanish glass, the other face lucifuges of camera bellows.
The camera lens of the industrial camera is undistorted industrial lens.
The length and width dimensions of the target surface are 20cm*20cm.
The beneficial effects of the utility model：
(1) position signalling of target is converted into position of the hot spot on fixture part, by spot signal
Processing calculates the position of glossing up, and then to the determination of target position information.
(2) positioning precision that the utility model is realized is up to 0.1mm, the effective recognition rate 100Hz of hot spot, small power consumption, reality
It is good with property, securely and reliably.

Reduce the interference of other extraneous light.
Camera lens selection is undistorted industrial lens, manual focusing, manual iris.
The laser generator transmitting laser 2 is beaten on target surface, and a hot spot 10 is formed on target surface 3, and target surface image is thrown
Shadow is sent to image processor 6 by USB serial ports 5 and carries out image procossing, image processor is at high speed image to industrial camera
Manage device, have small volume and it is in light weight the advantages of, laser generator is apart from about 5 meters or so of target surface in the present embodiment.
After image processor receives image, image is pre-processed, then enters row threshold division, spot identification, uses
Least square method obtains the center point coordinate of hot spot, and host computer is sent to finally by serial communication.
Host computer is computer in the present embodiment, either development board or other equipment for supporting RS232.
Above-described embodiment is the preferable embodiment of the utility model, but embodiment of the present utility model is not by described
The limitation of embodiment, it is other it is any without departing from Spirit Essence of the present utility model with made under principle change, modify, replace
Generation, combination, simplify, should be equivalent substitute mode, be included within the scope of protection of the utility model.
