SF6 instrument image light dark area,there are multiple reflections and shadows,defect recognition method based on single sensor is obvious. Therefore,the sensor array is introduced and the image recognition method of SF6 instrument is proposed. Using SONY's IMX219 as the core image sensor,the sensor array is designed to capture the SF6 instrument image information in all aspects,and the data collected by the sensor array is processed and transmitted in real time under TCP/IP protocol. Image denoising and multi-scale wavelet transform are used to obtain the texture features at different scales through feature vectors and similarity parameters. Support vector machine (SVM) recognition was used to recognize SF6 instrument image information. In the test results,the image recognition method designed in this paper not only has superior denoising effect,but also has lower error for the recognition results of specific symbols.
