The working process of the base station butt joint type water surface garbage collection device is divided into three steps, namely garbage collection mode judgment, garbage identification collection and positioning butt joint temporary storage:
the method comprises the steps that firstly, a collector takes pictures of a managed water area regularly through a recognition camera to obtain a real-time water surface image of a working water area, the area of the working water area is determined, the distribution position of garbage is found through a characteristic recognition algorithm in a collector single chip microcomputer, the garbage density is determined, and then a garbage collection mode is selected by the collector single chip microcomputer according to the relation that the garbage density has a garbage threshold value and is a cover cruise collection mode or directional feedback collection. In this embodiment, the garbage density threshold is set to 2/square meter, and can be adjusted according to actual requirements.
The flow and the function of the feature recognition algorithm are as follows: firstly, carrying out fuzzy processing on a water surface background, dividing a picture into 64 large image blocks, dividing 64 small image blocks in each large image block, and carrying out highlighting processing on the large image block with white garbage or similar white garbage characteristics (characteristics that the total area of the white or off-white small image blocks accounts for more than 75% of the area of the large image block), wherein the large image block is marked as garbage; then establishing a Cartesian coordinate system, labeling the highlighted large image block, calculating and recording the position of the labeled large image block, and converting the position of the large image block into the relative position of the actual garbage and the collector; and finally, calculating the garbage density in the working area by using a calculation formula of the garbage density which is the garbage number/working water area in the working water area, feeding back the position and the garbage density of the marked large image block to the collector single chip microcomputer, and performing subsequent path planning and other processing by the collector single chip microcomputer. The feature recognition algorithm can eliminate the negative influence of interference factors such as water surface waves on garbage recognition, and improves the accuracy and the processing efficiency of garbage recognition by dividing large image blocks and small image blocks.
Then, after the collection mode is judged, the collector starts to work in the working water area. If the working water area is in the covering cruise collecting mode, a covering path planning algorithm is operated by identifying a camera and a collector singlechip, the covering path planning algorithm collects garbage in the whole working water area according to a 'loop-shaped route' taking a base station as a center, the collection rule is that the garbage is collected from one corner of the water area, the first circle of the garbage passes through the most edge rectangle of the water area and returns to one corner of the water area, and the second circle of the garbage and the collection route rectangles thereafter are sequentially reduced by 5% of the side length;
after the collector singlechip judges that the covering cruise collection is finished, directional feedback collection is executed again, and the garbage in the water area is completely removed through secondary collection; if the directional feedback collection mode is judged, the position of the garbage is directly locked through a characteristic identification algorithm in a collector single chip microcomputer, the collector single chip microcomputer operates a feedback type path planning algorithm to conduct directional fixed-point collection, the feedback type path planning algorithm conducts fixed-point collection according to the garbage position determined in the characteristic identification algorithm, the collection rule is that one point in a base station or a water area is taken as a starting point, the garbage moves to a nearest garbage point, the nearest garbage is collected, after collection is completed, the garbage moves to the next nearest position and the garbage at the next nearest position is collected, and after all fixed-point garbage collection work is completed, the collector returns to the initial position to stand by or returns to the base station to discharge the garbage.
Finally, after the work of identifying and collecting the garbage is finished, the collector single chip microcomputer sends a signal to the base station single chip microcomputer to carry out the positioning work of the collector and determine the relative position between the collector and the base station; after the positioning work of the collector is completed, when the garbage detection module in the collector detects that the garbage in the garbage basket is fully collected, the path planning from the current position of the collector to the current position of the base station can be carried out according to the relative position information between the collector and the base station determined in the positioning work, the storage battery in the energy power module provides power for the propeller, the collector is driven to move to the base station according to the planned path from the current position of the collector to the current position of the base station, when the positioning butt joint camera 23 collects the area where the collector is close to the base station, the information is transmitted to the base station single chip microcomputer, the base station single chip microcomputer controls the automatic lifting door to lift, meanwhile, the collector single chip microcomputer signals are given to the collector, and the collector single chip microcomputer signals and the two are butted. After the collector enters the base station, the direct current screw rod motor on the second workbench drives the push plate in the collecting basket to push the garbage out of the opening of the collecting basket, when the collector single chip microcomputer judges that the garbage is completely pushed out of the collecting basket by the push plate (the push plate moves to the front limit position of the long strip hole), the screw rod direct current motor 19 is controlled to drive the push plate to return to the initial position (the rear limit position of the long strip hole), then the propeller is controlled to move reversely, the collector is retreated away from the base station, when the positioning butt joint camera collects that the collector completely leaves the base station, information is transmitted to the base station single chip microcomputer, the base station single chip microcomputer controls the automatic lifting door to be closed, the collector starts garbage collection work in the next water area, and the base station starts to wait for next butt joint.
The above is the working process of the docking type water surface garbage collection device of the base station.
The collector is divided into two working modes, firstly, covering collection is carried out according to a preset track, then directional collection is carried out according to image feedback signals, after the covering collection and the feedback collection are completed by the collector, the collector enters a base station for butt joint, and water surface garbage collection is carried out again after garbage is released.
Firstly, a recognition camera arranged on a first workbench shoots a working water area, after the shooting is completed, photo data are converted into analog signals and are transmitted to a collector single chip microcomputer through a DuPont line, then the collector single chip microcomputer extracts objects with garbage characteristics by applying a characteristic recognition algorithm to the photos, the positions and the quantity of the objects are calculated, meanwhile, the path planning from the initial position of the working water area to the end position of the working water area is completed, then, specific kinematic numerical values such as speed, straight-going time and turning time required by completing a corresponding path are compared with the running speed of a collector, the voltage and the power supply time required by a propeller are calculated by the collector single chip microcomputer, the digital signals are converted into analog signals, and the analog signals are output to the propeller. And finally, the propeller drives the collector to collect the garbage identified by the characteristics according to the calculated path.
