Detailed Description
Embodiments of a half-field capture mechanism switch control system of the present invention will be described in detail below with reference to the accompanying drawings.
In daily life, self-adaptation refers to a feature in which living beings change their habits to adapt to new environments. Thus, intuitively, an adaptive controller should be one that modifies its own characteristics to accommodate changes in the dynamics of the object and disturbance.
The self-adaptive control is the same as the conventional feedback control and the optimal control, and is a control method based on a mathematical model, and the difference is that the prior knowledge about the model and the disturbance, which is the basis of the self-adaptive control, is less, and the information about the model needs to be continuously extracted in the running process of the system, so that the model is gradually improved. Specifically, the model parameters may be continuously identified based on the input and output data of the object, which is called online identification of the system. With the continuous production process, the model becomes more accurate and closer to reality through online identification. Since models are constantly being developed, it is clear that the control actions integrated on the basis of such models will also be constantly being developed. In this sense, the control system has a certain adaptability. For example, when the system is in the design stage, the system may not perform well when being put into operation at the beginning due to the lack of initial information of the object characteristics, but as long as a period of operation elapses, the control system gradually adapts to adjust itself to a satisfactory working state through online identification and control. For example, in some control objects, the characteristics of the control objects may change significantly during operation, but the system can adapt gradually by identifying and changing the controller parameters online.
The conventional feedback control system has a certain inhibiting capability on the influence of the internal characteristic change of the system and the external disturbance, but because the controller parameter is fixed, when the internal characteristic change of the system or the change amplitude of the external disturbance is large, the performance of the system is often greatly reduced and even unstable. Adaptive control is appropriate for systems that vary widely in object or disturbance characteristics, and that often require high performance levels. It should also be noted, however, that adaptive control is much more complex and costly than conventional feedback control, and is therefore considered only when the desired performance is not achieved with conventional feedback.
At present, in the monitoring of a football field, besides a full field camera device is arranged above the football field to complete full field image data acquisition of the football field, because full field image data is not fine and smooth enough and the angle is fixed, a left half field capturing mechanism or a right half field capturing mechanism is generally introduced to respectively capture image data with a fixed angle and higher definition on different half fields of the football field. However, sometimes the football is often only frequently present in one half of the court, the capture mechanism in the other half will always be in an inoperative condition.
In order to overcome the defects, the invention builds a switch control system of the half-field capturing mechanism, and can effectively solve the corresponding technical problem.
Fig. 1 is a diagram illustrating an operation scenario of a first capture mechanism or a second capture mechanism of a half-field capture mechanism switch control system according to an embodiment of the present invention.

Some of the fastest GPUs integrate even more transistors than normal CPUs.
Most current GPUs have 2D or 3D graphics acceleration capabilities. If the CPU wants to draw a two-dimensional graph, only an instruction needs to be sent to the GPU, for example, if a rectangle with the length and width of a multiplied by b is drawn at a coordinate position (x, y), the GPU can quickly calculate all pixels of the graph, draw a corresponding graph at a specified position on a display, inform the CPU that the graph is drawn completely, and then wait for the CPU to send a next graph instruction.
