In value, the smallest and corresponding distance of value is determined as the corresponding target range of the ball machine symmetric points.
3. thunder ball sizing system as described in claim 1, which is characterized in that the thunder ball sizing system further includes laser designation
Lamp;Wherein, the mounting distance between the laser indicator lamp and the distance measuring sensor is less than preset distance threshold, and direction
Unanimously.
4. thunder ball sizing system as described in claim 1, which is characterized in that the distance measuring sensor includes:
Flight time TOF sensor or ultrasonic sensor.
5. thunder ball sizing system as described in claim 1, which is characterized in that the preset rotation step-length is 1 degree.
6. a kind of thunder ball sizing method, which is characterized in that the described method includes:
Control module controls one circle of ball machine rotation according to preset rotation step-length;And the every rotation of ball machine is primary, receives and surveys
The distance sent away from sensor;Wherein, the distance is the distance between itself and the ball machine that distance measuring sensor obtains;
According to each distance received, the corresponding target range of the ball machine symmetric points is determined;The target range is corresponding
Ball machine rotational angle as thunder ball sizing angle.
7. method as claimed in claim 6, which is characterized in that each distance that the basis receives determines the ball machine
The corresponding target range of symmetric points includes:
The each distance received is ranked up according to ball machine rotational angle, for each distance, determines with the distance and is
The heart, the absolute value of the difference of the symmetrical every two distance of two side positions, calculate this apart from corresponding each absolute value and value;
Each of will obtain and value in, it is the smallest to be determined as the corresponding target range of the ball machine symmetric points with the corresponding distance of value.
8. method as claimed in claim 6, which is characterized in that the distance measuring sensor includes:
Flight time TOF sensor or ultrasonic sensor.
9. method as claimed in claim 6, which is characterized in that the preset rotation step-length is 1 degree.
