Problems solved by technology
Hot Wheels, which are suitable for bicycle wheels, are realized through LED lights. If you display images or other imaging information, you will encounter such a problem: if you refresh and display LED data at a constant speed, it will cause the graphics to rotate or even blur the screen.
If a device such as Hot Wheels is installed on the wheel of a bicycle, gorgeous pictures and animations can be displayed, bringing a strong visual impact to the public

Embodiment Construction
[0031] A method for image stabilization based on gravity sensing, said method comprising the steps of:
[0032] a: Data collected by two gravity sensors;
[0033] b: Pre-judgment and filter the collected data. Since the speed of gravity sensor collection is relatively fast, the error of the collected data is relatively large. In order to calculate the angle in the next step more accurately, it is necessary to correct the large error data filtering;
[0034] c: Calculate the data obtained after filtering according to the following method to find the angle and angular velocity of the angle between the gravity of the gravity sensor and its centripetal force
[0035] Put two gravity sensors on the two ends of the same diameter of the circle, their centripetal force is equal and opposite without considering the gravity, the force situation is as follows figure 2 shown
[0036] The formula (1) obtained from the force analysis of the gravity sensor 1

The invention relates to an image stabilizing method, in particular to a method for stabilizing an image by processing an image shown during image rotation through a double-gravity sensor. An image stabilizing method based on double-gravity sensing comprises the following steps: a, acquiring data by using a gravity sensor; and b, pre-judging and filtering the acquired data, wherein data with large errors needs to be filtered in order to ensure high angle computation accuracy in a next step; computing the filtered data according to a method described below to obtain the degrees of an included angle between the gravity and the centripetal force of the current gravity sensor, and the magnitude of an angular speed; and refreshing display according to the degrees of the included angle between the gravity and the centripetal force of the current gravity sensor, pre-judging next data according to the magnitude of the angular speed, and adjusting the refreshing speed. Through the image stabilizing method, the same point is displayed once a circle rotates to the same angle or position, so that the aim of stabilizing the image is fulfilled.
Description
technical field [0001] The invention relates to a method for stabilizing an image, in particular to a method for using a dual force sensor to process an image presented when the image is rotated to achieve image stabilization. Background technique [0002] An important condition to achieve a stable effect for the image presented by rotation is that the same point should be displayed every time it is rotated to the same angle or position. If the rotation speed is faster than the display refresh rate, the image will be shifted in the direction of rotation. For example, the first 3 LED lights need to be lit at 0°, and these 3 LED lights are lit at 5° due to the sudden acceleration of the speed (the rest of the angles or positions are analogous in sequence). The direction of rotation is shifted by 5°. If this speed is increasing at a constant rate then the image will rotate in the direction of rotation. If this speed is reduced uniformly then the image will rotate in the oppo...
