Description

Technical Field

[0001] The present invention relates to the technical field of fishing devices, in particular to a device for real-time video recognition and feedback of a float and a method for implementing the same. Background Art

[0002] Fishing uses a fishing rod, fishing line, fishing hook and float lead sinker system. During fishing, people need to concentrate for a long time and pay attention to the various movements of the float to determine whether the fish has taken the hook.

[0003] However, the process of fishing requires you to concentrate on staring at the feedback from the float, which will make you very tired, and the interference and stimulation of various lights will make your eyes very tired. Summary of the invention

[0004] To this end, the present invention will solve these problems. The present invention provides a float auxiliary feedback device and method that frees both eyes, so that people do not have to keep their eyes on the float during fishing. The actual state of the current float can be linearly expressed through sound, electrical signals, vibrations, and light signals.

[0005] To achieve this technical solution, the device provided by the present invention includes: The camera unit is used to collect the floating video stream and output it to the computer video processing part. It has multiple optical and digital zoom for better shooting. The computer video processing unit is used to process the video stream captured by the camera, retrieve the current pixel height position of the floating feature object; and perform double smoothing filtering on the current height position, and output the filtered height position to the sound, electrical signal, vibration, light output, unit; A sound output unit, which outputs a sound whose frequency and volume are modulated by the current output height position signal, thereby being able to express the current height position information of the characteristic object at the end of the float; The electric signal output unit outputs a current signal expressing the height position of the characteristic object at the end of the current float. If the position moves upward, the output current will increase synchronously with the position. If the position moves downward, the output current will decrease synchronously with the position, thereby expressing the current position information of the end of the float in real time; The vibration output unit outputs a vibration signal expressing the current height position. The greater the input, the greater the vibration, thereby expressing the current float position information; The light output unit, the output light brightness is modulated by the position height information, and the change of light and dark represents the height position movement of the float; Display unit, displaying the current video stream to facilitate the positioning of the floating area, displaying the current setting parameters, and displaying the current real-time data information; Touch control unit to set parameters and other operations; Float features: Add feature graphics at the tail end of the float. These graphics include columns, diamonds, ellipses, circles, cones, and symmetrical shapes when viewed from the side, so that the NPU network model can detect the coordinates.

[0006] The float is in a suspended state and is relatively stable in height coordinates. The camera is aimed at the float to shoot. The computer video processing extracts the pixel coordinates of the characteristic object at the end of the float in the video stream. The current height of the characteristic object of the float is compared with the output of the second smoothing filter after the first filtering. When the bait under the water is eaten by fish, the float will fluctuate in the height coordinate, and the characteristic object at the end of the float will also fluctuate. The computer video processing will detect this fluctuation and characterize the change rate of the current movement of the end of the float through sound, electrical signal, vibration, and light output after filtering. That is, the greater the height change, the higher the output, and vice versa, the lower the output, so that the fisherman does not need to judge the current state of the float by visual inspection. BRIEF DESCRIPTION OF THE DRAWINGS

[0007] In order to more clearly illustrate the technical solution of the present invention, the accompanying drawings are used for a brief introduction.

[0008] Figure 1 A schematic diagram of the working of the real-time feedback device for floating provided by the present invention; Figure 2 This is a block diagram of the system working principle of the float real-time feedback device provided by the present invention. Specific implementation methods

[0009] In order to make the technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings.

[0010] In Figure 1, 101 is a real-time feedback device for floats, comprising a camera unit, a computer video processing unit, a display, a sound, electrical signal, vibration and light output unit, and a touch control unit; 102 a camera tripod for fixing the device; 103 a float feature installed at the tail of the float; 104 a water surface; working principle, the camera stand supports the real-time feedback device for floats at a suitable height, and shoots the float feature in the water. When there is no fish biting the hook, the float will stably float on the water surface, and similarly, the float feature installed at the tail of the float will also be stable in a fixed position. When a fish bites the hook, the float will move up and down, and at this time the float feature will also move together, which will be captured by the camera into a video stream and sent to the computer processing unit. After processing, the computer detects the floating of the feature, converts the floating into a signal and sends it to the output unit, which outputs the corresponding signal.

[0011] Figure 2 is a flow chart of the system working relationship. The video stream captured by the camera is input into the computer video processing unit to retrieve the coordinates of the floating feature objects. The output coordinates are input into a double filter and output to various subsequent output units after filtering and subtraction. The computer processing unit is also connected to the display and touch control unit.
