Fig. 2 image recognition formula water level acquisition instrument control circuit;
The image that Fig. 3 image recognition formula water level acquisition instrument gathers.
Embodiment
As shown in Figure 1 to Figure 3, image recognition formula water level acquisition instrument consists of a casing, high-definition camera 102 is installed on casing 101, in casing, there are wireless data transfer module 103 and control circuit, on control circuit, there are microprocessor 201 and picture recognition module 204, camera control signal, picture recognition module 204, wireless data transfer module 208 are connected with corresponding I/O port on this microprocessor 201 respectively, and the data-signal of camera 102 is connected with picture recognition module 204.In water level acquisition process, camera 102 is first facing to river bank vertical plane or inclined-plane pictures taken, on vertical plane or inclined-plane, there is the specific markers 301 drawing in advance, the height of water level of this mark is known, the picture of taking picks out the water surface 302 and specific markers through picture recognition module 204, and then the relative vertical range on photo calculates water level 302 height of the water surface with specific markers 301 by the water surface 302.Wireless transport module 208 can be passed the water level collecting back, can also upgrade firmware, transfer instruction.
In actual use, after image recognition formula water level acquisition instrument is installed, determine its height, with inclined-plane, river bank on horizontal level and the inclination angle of specific markers, highly, with inclined-plane, river bank on the horizontal range of specific markers can directly obtain by the method for measuring, inclination angle is difficult to measure accurately, in order to address this problem, can first with camera, take a photo, actual physical location at artificial cognition photo mid point, measured again, by trigonometric function, extrapolate the inclination angle of camera, record after these information, they are input to this device.
The installation of camera, does not need to preset its inclination angle, can first make it aim at the mark, then measures according to the method described above its inclination angle.
Camera 102 should form a pitch angle (acute angle) towards river plane and with river plane, and facing to the specific markers 301 on inclined-plane, river bank, the photo of taking should have the water surface 302, there is again the specific markers 301 on inclined-plane, picture recognition module 204 identifies these marks 301 and the water surface 302 on photo, and then just can extrapolate water level.
It is a plane that inclined-plane, river bank requires the region of identification, and the mark 301 on inclined-plane is wanted obviously, can be easy to by picture recognition module 204 identifications out.
As Fig. 2, the control circuit in the utility model also can comprise Wireless Data Transmission circuit 208, and the transmission ends of this Wireless Data Transmission circuit is connected with corresponding I/O end on microprocessor 201.
