Abstract

The invention discloses an intelligent indication method of a pointer instrument and a device thereof. The method comprises the following steps: obtaining an image to be processed from a video streaming, carrying out image median filtering processing and image enhancement processing on the image to be processed to obtain a primary-processing image; on the basis of an Otsu threshold value segmentation method, carrying out binarization processing on the primary-processing image to obtain a binarization image, carrying out Laplace transform on the binarization image, carrying out xor processing on the binarization image and an image obtained via the Laplace transform, and carrying out the median filtering processing on the image obtained by the xor processing to obtain a secondary processing image; carrying out refining processing on the secondary processing image, carrying out linear detection processing on the image obtained by the refining processing to identify a pointer straight line of the pointer instrument; and according to the parameter information of the pointer instrument and the identified pointer straight line, calculating a scale value where the pointer of the pointer instrument points to at the moment. The pointer identification robustness of the pointer instrument can be improved.

Description

technical field [0001] The present invention relates to the technical field of video monitoring, in particular to intelligent analysis in the field of video monitoring, in particular to an intelligent identification method and device for a pointer instrument. Background technique [0002] In the field of intelligent analysis technology in video surveillance, the recognition of pointer instruments refers to obtaining the real-time indication values ​​of pointer instruments within the scope of the target monitoring scene through some video processing methods and / or image processing methods. The processing method usually adopted in the prior art is: [0003] The first step is to acquire video streams, wherein the video streams come from cameras set up in various scenes. [0004] Secondly, capture the picture containing the pointer instrument from the video stream, do a series of image processing on the captured image, and finally obtain the real-time indication value of the po...
