Problems solved by technology

[0004] This measurement method mainly relies on the worker's visual inspection, the accuracy rate is relatively low, and its judgment standard is tangent to the edge of the atomization, using the position of a point on the edge of the atomization, so the randomness is relatively large, and it has not been fully utilized. Information on the entire fog edge

Embodiment Construction

[0024] The present invention will be further described in detail below in conjunction with the examples.

[0025] The technical scheme adopted in the present invention is: utilize image acquisition device to obtain digital image, write image processing algorithm based on Labview software development platform to carry out enhancement, edge detection, binarization to the collected image, remove arc point and thinning and other preprocessing, The two boundary lines of the spray cone angle are obtained by Hough transform in pattern recognition, and finally the atomization cone angle of the nozzle is calculated. The angle value is displayed on the man-machine interface.

[0026] Such as figure 1 As shown, the image acquisition device is composed of an industrial camera 2 and its internal digital I / O trigger interface card, a light source 1, and an explosion-proof industrial computer 3. The industrial camera 2 accepts an external trigger signal, takes an image, and when the shooti...

Abstract

The invention relates to a vision-based automatic aviation oil mist nozzle atomization angle detection device. A light source is arranged inside a tank, and an industrial camera is arranged on the outer side of the tank, connected with an explosion-proof computer through an internal digital I / O (input / output) trigger interface card and used for shooting spray of the oil mist nozzle fixed in the tank. A detection method includes the following steps that the industrial camera shoots a digital image of a spray cone angle by receiving an external trigger signal and sends the digital image to the explosion-proof computer; the explosion-proof computer preprocesses the digital image to obtain a binary image; the binary image is subjected to Hough transform to obtain a boundary of degrees of the cone angle and the degrees of the cone angle. By the device and method, the problem about randomness of manual measurement of the aviation nozzle is solved, accuracy is improved, reliability in measurement is guaranteed, and automation level is heightened.
