Abstract

A combination float for fishing and a video capture and data transmission system (1 ), the combination including a semi-submersible elongated hollow float (2) containing a battery operated video camera (8) and data transmitter, the transmitter being disposed within the upper part (2b) of the float above the waterline when the float is in use, the camera having its optical axis pointing downwardly below the waterline, and a viewing window (3) in the bottom (2a) of the float through which the camera can view the local area of water within which the combination is floating, the arrangement enabling real-time video images to be captured and transmitted to a remote interface, such as a mobile phone.

Description

This invention relates to a combination fishing float for use in aquatic activities such as line fishing,
Line fishing or angling is a very popular participation sport in which food bait or artificial bait is attached on or near a fishing hook which may itself be held at a constant height below the surface of the water being fished by means of a float, and for bottom-dwelling fish the hook and line adjacent to it may be slideably held down by a heavy weight such as a lead weight or ledger so as to keep the bail; and hook at the bottom of the area being fished. A third form of fishing is known as trolling in which a line and associated hook and bait are dragged through the water by a powered boat, this being a particularly popular method of catching large fish such as tuna and mar!in. However, in all three methods of fishing it is generally the case that the choice of where to fish is reliant to a large extent on chance, particularly where the water is discoloured so that the presence of fish cannot be easily discerned by the angler.
It is known to use a video capture system associated with fishing lines and EP2136561 describes a system whereby a video camera is connected to a fishing Sine adjacent to the baited end, primarily to record the moment of capture, When the fish has taken [he bait it is then hauied out of the water along with the video camera and associated floating transmitter.
In CN201499531 there is described a similar arrangement in which a video camera and associated transmitter are connected to the fishing line near to the fish hook so that the angler can observe underwater conditions at any time, thereby providing the angler with the choice of continuing to fish in that area or reeling in the line along with the hook and associated camera to try again at a different location.
Although the foregoing devices can, respectively, show a fish as it is being captured or allow observation of the conditions immediately surrounding the baited hook, it will be apparent that a disadvantage of each is that the field of view is restricted to the immediate area around the hook as a consequence of the direction of view and proximity of the submerged camera adjacent the hook. In addition the video capture system adds an unnecessary additional element to the anglers' fishing equipment.
The present invention is derived from the realisation that there exists a need to observe or otherwise monitor conditions underwater over a larger area of water such that they indicate e.g. the presence or absence of fish, or the initial presence and subsequent absence of fish in that area.
According to a first aspect of the invention there is provided a combination fioat for fishing and a video capture and data transmission system, the combination including a semi-submersible elongated hollow float containing a battery operated video camera and data transmitter, the transmitter being disposed within the upper pari of the float above the wateriine when the float is in use, the camera having its optica! axis pointing downwardly below the wateriine, and a viewing window in the bottom of the float through which the camera can view the local area of water within which the combination is floating, the arrangement enabling real-time video images to be captured and transmitted to a remote interface, such as a mobile phone. With, this arrangement the angler can attach the float containing the camera in the normal way to the line of a fishing rod via an eyelet. The angler would then select an area to be fished and can then cast the line into the area of interest, whereafter on receiving visual reconnaissance of the fishing area from the camera within the float the angler can decide whether to retrieve the line for use in another area or let it remain where it is if the presence of fish is noted.
According to a second aspect of the invention there is provided a combination float and video capture and data system according to the first aspect of the invention together with a casting weight and associated fishing line by which one or more such combination floats can be cast into an area of interest, such as by hand casting, whereafter the vertical position of the float and hence camera can be adjusted from floating on the surface to being submerged immediately above the casting weight by adjusting the tension on the fishing line.
With this arrangement one or several combination fishing floats, each with a video camera, can be cast over a wide area and their respective heights relative to the bed of the waterway being fished can be adjusted depending upon e,g. the clarity of the water, and also to record and transmit fish activity, such as the moment of fish capture during conventional fishing or fishing using the combination fishing float according to the first aspect of the invention.
The invention will now be described, by way of example only, with reference to the accompanying drawings in which:-
Figure 1 is a side view of a combination fishing float and video capture system in accordance with the first aspect of the invention, Figure 2 is a perspective view of the system of Figure i , Figure 3 is a cross-sectional view along the line "A-A" of Figure 4,
Figure 4 is a front end view of the system of Figure 1 ,
Figure 5 is an exploded side view of the system of Figure 1. and
Figure 8 is a schematic representation of a second embodiment of the invention showing an array of two combination floats tethered above respective casting weights by fishing lines.
Referring firstly to Figure 1. there is shown a combination fishing float and video capture system show generally at 1 deployed in open water whereby the float has a watertight outer housing 2 so as to protect, the camera and Internal electronics (to be described later). The watertight housing 2 of the float 2 is shown semi-submersed and is internally weighted such thai, when deployed, the lower bulbous end 2a is below the waterline and points downwards. The bulbous end 2a is terminated by a window 3 (shown more clearly in Figure 2) through which light may pass to an internally mounted video camera 8 (shown in Figure 3). The upper end 2h of the outer housing 2 Is terminated by a removable end cap 4 which, in operation, remains above the surface of the water but is nevertheless watertight when fitted to the bousing 2.
The end cap includes four radially spaced-apart end cap fins 5 to improve the aerodynamics of the housing 2 as the float is being cast on a fishing Sine and one fin of the end cap includes a line connection means in the form of an eyelet or hole 8.
In use a fishing line is attached, in the normal way, for example threaded through the eyelet 6. The line continues through the eyelet such that the weight and hook of the line extends a spatial distance apart from the float 1 Connecting the float in this way to the line enables casting of the entire system into the wafer and further enables safe retrieval after use.
The shape of the waterproof housing 2 and internal weight distribution allows the float to self-orientate when deployed in open water such that the window 3 at the bulbous end 2a is directed below the surface of the wafer and points downwardly towards the bottom of a watercourse. The outer housing 2 also includes stabiliser means in the form of a pair of oppositely disposed elongated side fins 7 which serve to inhibit rotation about the longitudinal axis of the housing 2. Any flow of wafer around the housing, such as by u and down movement caused by waves or ripples, or transverse movement caused by a current, is therefore at least partially counter-balanced by the presence of the elongated side fins ?.
Referring now to Figure 3, it is shown that the outer housing 2 encases a HO digital camera 8, a digital video processor (not shown) and a rechargeable power source in the form of a rechargeable battery 9 which powers the camera 8 and other associated electronics. The optical axis of the camera 8 is aligned with the longitudinal axis of the housing 2 and the light collecting end of the camera is positioned in front of the window 3 enabling the passage of light into the camera 8. This enables the Sight collecting end of the camera 8 to he biased to point downwards towards the watercourse, and consequently optimises the qualify of the view underwater.
The elongated sicie fins 7 of the oute housing are arranged coaxially with the optical axis of the camera 8. This arrangement ensures that the side fins inhibit rotation and yaw of the camera 8 about its optical axis when the housing 2 is semi-submerged resulting in an improved image being obtained., therefore improved surveillance of fish below the waterline over a relatively wide field of view as compared to the arrangements shown in the prior art
The camera B is used to capture a video stream of the scene below the surface of the water using a wide angle lens. The wide field of view lens may be provided by the window 3 instead of the camera 8. An HD camera S is chosen over standard definition cameras since it provides a clearer view. The HD camera also permits digital effects for object and motion detection. The digital video processor (not shown) provides compression of the raw digital video signal coming from the camera 8 and follows the latest compression standard of H.284. This provides much better bandwidth efficiency compared to a motion JPEG or a SvlJPEG.
A transmission means in the form of a wireless module (not shown) is positioned within the upper part of the watertight housing 2 that lies above the waterline. The wireless module is used for transmitting the processed video stream in real-time over to a remote interface device of a user, for example a smart phone, and is capable of covering distances of up to e.g. 100m in clear view. The user can then view the video captured by the camera 8 in real-time and ascertain whether, or not, the area surveyed contains any fish.
The end cap 4 is removable so as to access a connector 10 positioned on the upper end of the housing 2b. The connector is a USB connector and can be used for recharging the rechargeable battery 9, for granting cable access to the video stream, or to provide both uses. The battery 9 is a Li-Ion re-chargeable battery and is chosen because it provides high current discharge at light weight, high voltage and high energy density. The Li-ion re-chargeable battery provides a minimum of 2.5 hours of operation time.
As an alternative to the compression of the video stream, the digital video processor can instead provide motion detection, LED or iris control or can simulate night vision.
The waterproof housing can be made from a first and second part capable of being separabiy fixed together, for example via a screw and thread assembly, so as to enable access to the camera, battery and electronics within, Alternatively, such access may be denied by forming the housing in a single part.
Although the float can he used in combination with a line of a fishing rod. in an alternative embodiment the float can be thrown manually without use with a fishing rod and can be used to survey below the waterline prior to the angler casting their fishing line connected to their fishing rod. In this manner the float would still be connected to a line via the eyelet so as to retrieve the fine after underwater reconnaissance has been carded out.
Figure 6 shows a second embodiment of the invention in which a pair of modified combination floats 1a are each shown tethered to respective fishing lines 11 , 12 via eyelets 8a positioned at the lower end of the float la instead of the eyelet 6 shown at the upper end of the float 1 described with reference to Figures 1 to 5. The fishing lines 11 , 12 are slideahiy secured to respective casting weights 13, 14 having sufficient mass to resist movement, by e.g. water currents, such that the vertical position of each of the floats la can be controlled. This allows a considerable field of vision in the area being observed by the video cameras in the floats ia but in the event that the water in which they are floating is unclear or in the event that close-up images of e.g. fish being caught are required it is simply necessary to increase the tensio on the fishing lines 11 ,12 by pulling them in the direction arrowed to thereby cause each float la to sink to a required depth, with the tension in the lines 11 , 12 serving to steady each float la, even in a relatively strong current, so that they point directly at their respective casting weights 13, 14, To prevent the float la from tilting to one side as it is being pulled below the surface a 3-poinf bridle or similar arrangement may be used to keep the float in an upright position.
As will he apparent, with such an arrangement it is possible to greatly improve the view of the area being fished and, by adjusting the tension in the lines 11 , 12 close-up shots of fish being caught can be taken and recorded, although it vvil! be understood that the invention in both its aspects is not limited to use in the sport of fishing and may be used instead to map areas underwater and record events, such as events during scuba diving in real-time. Similarly, the invention also has uses in e.g. robotic activities such as mining or recovery of lost valuables where the field of view of the search area can be monitored as a means of assisting in the recovery operation.
