Problems solved by technology

[0007] In summary, the disadvantages of the cricket system in the prior art also include: 1. The mechanical structure of the cricket system is complex, and the complex mechanical structure will introduce too many error sources, which will affect the control accuracy
2. Most of the cricket systems in the prior art are driven by stepping motors. The disadvantage of using stepping motors is that it is easy to generate resonance, and it is difficult to run to a higher speed to obtain a larger torque; there is no such thing as volume and weight. Advantages, and low energy utilization; when the stepper motor exceeds the load, it will break the synchronization, and it is easy to emit vibration and noise when working at high speed
3. Most of the existing cricket systems are driven by one or more motors, and the control problem of multiple degrees of freedom needs to be considered, and the control method is complicated

Embodiment 1

[0041] Such as Figure 1-2 shown.

[0042] A coplanar cricket experiment system based on image processing, comprising a platform support 6, a steering frame 3, a platform 4 and an ARDUINO control module 7;

[0043] The steering gear frame 3 is set on the platform support 6 through the rotation of the first steering gear 10 and the second steering gear 11, and the platform 4 is set on the steering gear frame through the rotation of the third steering gear 2 and the fourth steering gear 9. 3; the rotation direction of the steering gear frame 3 is perpendicular to the rotation direction of the platform 4; an image acquisition and processing module 1 is arranged above the platform 4; a small ball is arranged on the upper surface of the platform 4; the first The steering gear 10, the second steering gear, the second steering gear 11, the third steering gear 2, the fourth steering gear 9 and the image acquisition processing module 1 are respectively connected with the ARDUINO contr...

Embodiment 2

[0045] Similar to the image processing-based coplanar cricket experimental system described in Example 1, the difference is that the platform 4 is a white flat plate structure, and the balls are black balls. The graphics processed by the cricket system are pure black balls, and the background is a pure white flat plate, so there is no need to use too complicated contour extraction methods.

Embodiment 3

[0047] As in the coplanar cricket experimental system based on image processing described in Embodiment 1, the difference is that the ARDUINO control module 7 is connected to the first steering gear 10, the second steering gear 11, and the third steering gear through the motor drive module 5 respectively. 2 is connected with the fourth steering gear 9. The motor drive module 5 amplifies the power of the control signal sent by the ARDUINO control module 7 and realizes control synchronization.

Abstract

The invention relates to an image processing based coplanar ball-plate experiment system and an operating method thereof. The image processing based coplanar ball-plate experiment system adopts a coplanar structure form, and is characterized in that a steering engine used for controlling two-dimensional movements of a flat plate is arranged on a plane, thereby reducing the Abbe error, reducing theerror source, achieving zero error of a platform geometric structure, and effectively overcoming defects of a stack structure.

Description

technical field [0001] The invention relates to an image processing-based coplanar cricket experiment system and a working method thereof, belonging to the technical field of electromechanical control. Background technique [0002] The cricket system is based on the study of the control algorithm, by controlling the swing angle of the tablet and the speed of the ball to realize the fixed point of the ball on the tablet, the automatic trajectory and the autonomous obstacle avoidance function.
