Embodiment Construction

[0033] The technical solutions of the present invention are described in detail below.

[0034] The invention intends to solve the algorithm problems of image recognition, noise overcoming and time calibration, as well as the actual optimization problem of different requirements for mobile phone processors.

[0035] The extraction of the surface pointer already has the image extraction. However, due to the problems of light and color in the image extraction, it is difficult to determine the position of the pointer more accurately for a single picture, and the shooting of multiple pictures is due to the time interval of shooting. As a result, there is a very high probability that the pointer will move.

[0036] The present invention adopts the method of extracting pictures from the video, the video has continuity, and many frames of pictures can be extracted in one second from the video, and the position of the pointer remains basically unchanged when processing some of the fra...

Abstract

The invention relates to a method for determining the physical pointer of a smart watch based on an Android system. Step 1 is to set the camera of a mobile phone including a processor with an installation system, so that the camera focuses at least once every time threshold. Step 2, the camera captures the surface of the watch in real time to obtain a video, and the mobile phone recognizes the video captured by the camera, and the recognition is to extract an image of the video for recognition. Step 3, performing positioning preprocessing on the extracted image of the video, the positioning preprocessing includes graying the image so that a 1-channel grayscale image is generated from a 4-channel image, and performing Gaussian filtering to obtain a smooth grayscale image. When evaluating the calculation speed required by the processor for many times, it was found that factors such as light and color have great obstacles to the extraction of subsequent pointers. Therefore, the conventional 4-channel image is directly reduced to 1 boldly and creatively. The grayscale image of the channel is processed, which not only speeds up the processing, but also reduces the requirements for the performance of the mobile phone.

Description

technical field [0001] The invention relates to a method for determining the position of a surface pointer, in particular to a method for determining the position of a physical pointer of a smart watch based on an Android system. Background technique [0002] At present, the calibration of smart physical pointer watches is more troublesome, requiring naked eye recognition and manual adjustment. Our company has developed a method of time synchronization by taking pictures. This method gives the mobile phone a very accurate premise for taking pictures and recognizing the picture. Moreover, the picture taken is an instantaneous action, and the picture is fixed. After the picture is taken, it is processed During the completion period, the time is moving. Therefore, there may be certain errors in this process, and a large number of correction algorithms are required to correct the time. Contents of the invention [0004] Based on the above-mentioned technical problems, the pre...
