Problems solved by technology
[0003] Acquisition of electric meter images is the first step in the whole process. The quality of the collected electric meter images (referring to whether the electric meter is centered and not tilted) will affect the effect of subsequent intelligent algorithm analysis. At present, there is no related method to assist in taking photos of electric meters.

Embodiment Construction
[0029] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings, but the present invention is not limited to these embodiments.
[0030] The basic idea of the present invention is to display an auxiliary frame on the camera interface for different photographing modes of the image acquisition device, and the user takes pictures according to the auxiliary frame to ensure that the collected image is in the middle of the screen without tilting.
[0031] Based on the above ideas, this embodiment proposes a gyroscope sensor-based auxiliary meter image acquisition method, which is applied to the acquisition of electric meter images through an image acquisition device. The image acquisition device is equipped with a gyroscope sensor, such as figure 1 As shown, the method includes the following steps:
[0032] S1: Determine the photographing mode of the image acquisition device.
[0033] Usually, when the installa...

The present invention relates to the field of image acquisition technology, in particular to a method for auxiliary acquisition of electric meter images based on a gyroscope sensor, comprising the following steps: judging the photographing mode of the image acquisition device; if it is in the forward mode, drawing a vertical line, and according to The vertical line draws the auxiliary frame of the camera interface, and collects the meter image according to the auxiliary frame; if it is in the upward shooting mode, draws the vertical line and establishes a three-dimensional coordinate system; obtains the rotation of the image acquisition device around the X axis through the gyroscope sensor Angular velocity and rotation time, and real-time calculation of the rotation angle of the image acquisition device around the X-axis; draw the real-time auxiliary frame of the camera interface according to the rotation angle of the image acquisition device around the X-axis, and collect the meter image according to the auxiliary frame. The invention ensures that the collected image is in the middle of the screen without inclination, so as to obtain a high-quality image in which the electric meter is centered without inclination.
Description
technical field [0001] The invention relates to the technical field of image acquisition, in particular to a gyroscope sensor-based auxiliary image acquisition method for electric meters. Background technique [0002] In the power grid system, the collection and inspection of electric energy meter data requires on-site audit by professionals, which consumes a lot of manpower and material resources. Through the development of mobile phone applications, electric power personnel collect electric meter images and upload them to the server, and then intelligently monitor the appearance of the meter box. Evaluation, such as judging and evaluating the type and installation location of the meter box, can achieve intelligent monitoring of the meter box, which can greatly save manpower and material resources. [0003] Acquisition of electric meter images is the first step in the whole process. The quality of the collected electric meter images (referring to whether the electric meter ...
