Abstract

The invention discloses a speed acquisition method and device, electronic equipment and a storage medium, and the method comprises the steps: obtaining rotating wheel feature data and latitude and longitude position data, the rotating wheel feature data being three-axis acceleration or magnetic force intensity and corresponding moments, and the latitude and longitude position data being latitude and longitude coordinates and corresponding moments; preprocessing the runner characteristic data and the longitude and latitude position data respectively; judging whether the current riding state is normal or not according to the preprocessed rotating wheel characteristic data, and if the current riding state is normal, calculating rotating wheel angular velocity data according to the preprocessed rotating wheel characteristic data; and calculating a wheel diameter value according to the rotating wheel angular velocity data and the preprocessed longitude and latitude position data, optimizing the wheel diameter value, and obtaining a current velocity value based on the optimized wheel diameter value. The technical problem that the riding speed cannot be effectively calculated at present is solved.

Description

technical field [0001] The present invention relates to the technical field of riding equipment, in particular to a speed acquisition method, device, electronic device and storage medium. Background technique [0002] The traditional speedometer based on the wheel system needs to manually input the accurate wheel diameter value (cycle-displacement gain), based on which the riding speed is calculated, and has a large dependence on this value, and accurate wheel diameter information must be obtained. , if the accuracy of the information is not high, the calculated speed error will be very large; and, after the wheel is replaced, the input wheel diameter information needs to be re-initialized, so the user experience is poor. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to overcome the above technical deficiencies, provide a speed acquisition method, device, electronic device and storage medium, and solve the technical problem that the riding speed...
