Embodiment Construction

[0018] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0019] see figure 1 , figure 1 It is a schematic flow chart of the method for image recognition reading and safety warning of a pointer instrument in the present invention. The method includes the following steps:

[0020] Step S101: Obtain a reading template picture of a standard pointer instrument, and remove the pointer area in the reading template picture, so that the reading template picture only contains scales and text.

[0021] It should be understood that the reading template picture in this embodiment is a standard pointer instrument, and the scales and characters in the reading templa...

Abstract

The invention discloses a pointer type instrument image identification reading and safety early warning method. The method comprises the steps of using a camera for shooting the reading of a pointer type instrument installed on equipment to obtain a shot picture; matching the shot picture with the reading template picture, and correcting the shot picture; obtaining a first annular region of interest in the shot picture; obtaining an annular second region of interest in the reading template picture; subtracting the first region of interest from the second region of interest to remove scales andcharacters in the second region of interest; identifying a pointer region in the second region of interest, and converting a reading value of the pointer region in the second region of interest according to the scale range; judging whether the reading value is in a dangerous area or not; and if so, generating an alarm. Through the mode, the method disclosed by the invention can realize automaticreading and automatically judge whether the reading of the pointer type instrument is in a dangerous area or not, so that the working efficiency is effectively improved.

Description

technical field [0001] The invention relates to the technical field of pointer meters, in particular to a pointer meter image recognition reading and safety warning method. Background technique [0002] At present, there are pointer instruments on the market for measuring temperature, air pressure, electricity, blood pressure, and flow. They look like timekeeping watches and can directly display values ​​​​from the scale. Among them, pointer instruments are mainly divided into pressure instruments, temperature instruments, flow instruments, electrical instruments, electronic measuring instruments, optical instruments, analytical instruments, experimental instruments, etc. [0003] At present, most of the readings of pointer instruments rely on manual reading, which has low work efficiency, and whether the readings of pointer instruments are in a dangerous area also requires manual judgment, which is low in work efficiency and greatly reduces the user experience. .
