and the fan-shaped central line of the radar fan-shaped image is consistent with the Z-axis direction of the mobile phone gyroscope.
By way of illustration of the present embodiment: if the sector angle of the radar sector image is 45 degrees, and the sector center line of the radar sector image is overlapped with the Z axis of the mobile phone gyroscope, the sector angles on two sides of the Z axis position of the mobile phone gyroscope, namely two sides of the radar sector image center line, are 22.5 degrees respectively.
Fig. 3 is a schematic diagram of three axes of a mobile phone gyroscope according to an embodiment of the present invention, and please refer to fig. 3 for the positions of the X axis, the Y axis, and the Z axis of the mobile phone gyroscope.
Based on the above embodiment, in step S100, if it is determined that the rotation angular velocity of the mobile phone gyroscope reaches the first preset threshold, displaying the radar sector image in the target image, where the method further includes:
and acquiring the Z-axis rotating angular speed of the mobile phone gyroscope, and judging whether the Z-axis rotating angular speed reaches a first preset threshold value.
In this embodiment, it is determined whether the rotational angular velocity of the gyroscope of the mobile phone reaches a first preset threshold, and it is mainly determined whether the rotational angular velocity of the Z axis reaches the first preset threshold. Specifically, the Z-axis rotation angular velocity of the mobile phone gyroscope needs to be continuously obtained, and the Z-axis rotation angular velocity is compared with a first preset threshold value, so that whether the Z-axis rotation angular velocity reaches the first preset threshold value is judged.

In the embodiment of the invention, the mobile phone gyroscope needs to be collected first when the rotation angular speed of the mobile phone gyroscope needs to be obtained. Specifically, in this embodiment, all sensors in the mobile phone are acquired, and a gyro sensor is found in all the sensors, which is to prevent an application program from being abnormal because some mobile phones are not configured with a gyro sensor. When the gyroscope sensor axis is found and the gyroscope sensor is registered, the values of the angles of the gyroscope can be obtained through the relevant class of the gyroscope sensor.
Specifically, in order to implement the above process, a developer may instantiate a management class SensorManager of the device sensor, and then globally traverse the sensors of the management class SensorManager instance of the device sensor, thereby taking all the sensors; the gyro sensor is then found among all sensors, and if present, registered. Further, the monitoring class of the sensor, such as SensorEventListener, may be inherited to implement the method corresponding to the change in the sensor value, so that the method needs to be acquired, and the method corresponding to the change in the sensor value is named onsensor changed, and the rotational angular velocity required by the embodiment of the present invention may be acquired by the onsensor changed method.

s101.2, redrawing the radar sector image, and enabling the newly drawn radar sector image to rotate around the preset area and the preset point by a preset angle relative to the original radar sector image, wherein the preset angle is the rotation angle.
Specifically, to realize that the radar animation rotates along with the rotation of the mobile phone gyroscope, the rotation angle of the mobile phone gyroscope needs to be acquired in real time, and the real-time acquisition is realized through a preset time interval, namely the rotation angle of the mobile phone gyroscope is continuously acquired within a short time interval, so that a real-time effect is achieved.
Specifically, the rotation angle of the mobile phone gyroscope can be obtained by calculation according to the rotation angular velocity of the Z axis and the current time value of the gyroscope, and the calculation formula is as follows:
the rotation angle is equal to the rotation angular speed of the Z axis.
The unit of the time value of the mobile phone gyroscope is nanosecond, and the rotation angle needs to be calculated after the unit of the time value is converted, for example, the unit is converted from nanosecond to second, and the conversion ratio is 1.0f/1000000000.0 f.
After the rotation angle of the mobile phone gyroscope is obtained, the radar sector image can be redrawn according to the rotation angle of the mobile phone gyroscope, so that the central line of the radar sector image is always consistent with the Z axis of the mobile phone gyroscope, and radar animation in which the radar sector image rotates along with the rotation of the mobile phone gyroscope is realized.
Based on the above embodiment, in step S101, the obtaining a rotation angular velocity of the mobile phone gyroscope and a current time value of the mobile phone gyroscope, and setting an angular position of the radar sector image according to the rotation angular velocity and the current time value further includes:
and if the fact that the Z-axis rotating angular speed of the mobile phone gyroscope is smaller than a second preset threshold value is detected, the radar sector image is not displayed.
According to the embodiment of the invention, the radar animation is started after the rotation angular speed of the mobile phone gyroscope is increased to reach the first preset threshold value, and correspondingly, the radar animation can be stopped after the rotation angular speed of the mobile phone gyroscope is decreased to reach the second preset threshold value, namely, the radar sector image is not displayed. Generally, the difference between the second preset threshold and the first preset threshold is within a certain difference range, for example, the first preset threshold is 0.15rad/s, the second preset threshold may be 0.15rad/s, or 0.1rad/s, or 0.2rad/s, and then the difference range is 0.05rad/s, that is, the gyroscope speed when the radar animation stops may be near the gyroscope speed when the radar animation is turned on; preferably, the gyroscope speed when the radar animation is stopped is the same as the gyroscope speed when the radar animation is turned on.
In summary, the embodiment of the present invention provides a radar animation display method based on a mobile phone gyroscope, so that hardware sensor information is visually displayed in a radar animation form; the starting time of the radar animation and the sector angle of the radar sector image can be controlled, many actual requirements can be met through self-defining of the starting time and the sector angle, most requirements for the animation based on a sensor can be met, hardware information is associated with page display, and interaction is achieved well. In addition, the size of the sector of the radar animation, the specific shape of the sector, the color, and other changes may also be set according to actual needs, which is not specifically limited in the embodiment of the present invention.
