Digital display instrument data recording method using target tracking algorithm

Abstract

The invention discloses a digital display instrument data recording method using a target tracking algorithm. The method can be used when data of a digital display instrument without a data output interface needs to be recorded. An instrument digital display window needing to be recorded in continuous image frames can be tracked in real time by using a target tracking algorithm. After the tracking window in the image frame is cut, the tracking window is sent to the rear end for optical character recognition and data recording, so that the data processing amount of the rear end is reduced, and the influence of irrelevant backgrounds on optical character recognition is avoided. The instrument is simple and convenient to use and operate, and the data of the digital display instrument can be conveniently recorded by using handheld camera equipment under the condition that the data of the digital display instrument needs to be recorded outdoors or temporarily.

Description

technical field [0001] The present invention relates to a method for acquiring instrumentation data, in particular to a method for recording data of a digital display instrument using a target tracking algorithm. Background technique [0002] In the process of engineering testing and instrument debugging, it is often necessary to record the measurement data of instruments and meters, which includes short-term single value records and long-term continuous data records. For instruments and meters with data output interface, it is very convenient to carry out the above data storage and recording. However, for field work, or some instruments and meters without data output interfaces, manual recording operations can only be performed through their digital display windows. During the long-term data recording process, the manual recording work will become very heavy, and it is difficult to quickly and accurately record some values ​​that change frequently. For this reason, the in...

Problems solved by technology

This method is not suitable for situations where digital display instruments are dense in the image frame, the surrounding environment is complex, and the recording shakes are obvious.

When manually reading the value, it is necessary to repeatedly search for the digital display instrument to be recorded between frames, and the complex environment or other non-reading target digital display instruments may interfere with the optical character recognition
