Problems solved by technology
[0003] The above situation has caused the following problems: (1) users often place the remote controller carelessly or carelessly, making it difficult to find the controller when actually using it, which adds trouble to the use; and some children do not know how to use the remote controller. If you don’t want to use a device, or you are unwilling to use it, and want to interact with the toy at the same time, trouble will arise; (2) the existing target tracking part based on the camera needs a very complicated algorithm, and the software cost often increases; (3) When doing some human-computer interaction, such as lectures on the podium or when you are far away from the equipment, when you cannot touch some traditional input devices, it will also cause trouble

Embodiment Construction
[0021] Hereinafter, the invention will now be described more fully with reference to the accompanying drawings, in which various embodiments are shown. However, this invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.
[0022] In the following embodiments and accompanying drawings, the applicant provides an example with a camera, a bright spot, and a set of control systems. It is feasible to use other numbers or install cameras and bright spot generators in other positions arbitrarily, according to the content of the invention .
[0023] Those skilled in the art can understand that for the whole system, its bright spot generator parts can be mobile phone flashlight, laser pointer, wearable button light spot generator (can be clipped o...

The invention discloses a camera-based bright spot tracking system and method. The camera-based bright spot tracking system comprises an ordinary camera and a threshold value comparison module, as well as a bright spot generator and a control module. The camera is connected with the control module; the bright spot generator can generate one or more laser spots or other bright spots, and the control module includes a single chip computer and a motion control part. At least one camera can move along with the threshold value comparison module and the control module, or does not move along with the threshold value comparison module and the control module; all the one or more bright spots can be captured by the camera. The camera-based bright spot tracking system can simply, efficiently and reliably realize the functions that the camera recognize bright spots and a motion system tracks the bright spots, avoid the utilization of a complicated image processing algorithm, in addition, the system development cost can be lowered, multiple advanced functions of dynamic bright spot recognition, bright spot drawing and the like can also be easily realized, and the camera-based bright spot tracking system can serve as a new man-machine interaction mode.
Description
technical field [0001] The invention relates to a software drive based on a camera, a single-chip microcomputer application integrated circuit, and a motor hardware drive, and belongs to the fields of camera identification and motion control. Background technique [0002] In modern life, on the one hand, all kinds of remote control toy cars used by people are controlled based on RF radio frequency or wired remote control handles, so that the use of toys or equipment can be realized without the user moving; on the other hand On the one hand, general target tracking relies on image recognition algorithms; on the other hand, in terms of human-computer interaction, it is generally necessary to use keyboards, mice, touch screens, etc. to exchange information with the machine as the hand contacts to make it move. [0003] The above situation has caused the following problems: (1) users often place the remote controller carelessly or carelessly, making it difficult to find the cont...
