Problems solved by technology

When encountering extreme weather, or the measurement area of ​​the water gauge is caused by war, the surveyor cannot reach the observation point and read the data
At present, ultrasonic and other fully automatic water level measuring instruments usually need to rely on electric power, integrated circuits and network communication to complete the data transmission. In the wading environment under extreme weather or war conditions, the reliability of field electronic equipment is greatly reduced. At this time, there is an urgent need A machine-recognized water gauge that can be applied to unmanned reconnaissance aircraft or robot dogs with cameras

Embodiment Construction

[0013] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0014] A low water resistance water level gauge based on machine identification has a hole code 3 arranged in the downstream direction through the ruler body 1. The hole code 3 is arranged in sequence on the ruler surface to form a hole code array, and the edge of the ruler body 1 is arranged. There is a pair of mark 2 installed. The paired mark 2 is composed of black and white strips with different lengths.

[0015] In operation, a low water resistance water level gauge based on machine identification is fixed at the position to be measured, and the water flows through the hole code 3 of the ruler body 1. Based on the camera mounted on the drone or robot dog, the ruler body 1 is photographed. , through the relative position of the edge of the ruler body 1 to the marking code 2, extract the hole code array from the water surface to the top of the ru...

Abstract

The invention discloses a low-water-resistance water gauge based on machine recognition. Hole codes in the downstream direction are arranged on a ruler body of the device in a penetrating mode, the hole codes are sequentially arranged on the ruler face to form a hole code array, and benchmarking codes are installed on the edge of the ruler body. The device is simple in structure, water resistance can be reduced, meanwhile, quick recognition of machine vision is met, errors caused by manual reading are avoided, and particularly in special environments such as flood and other natural disaster areas or warfare areas, the water level can be quickly read through an unmanned aerial vehicle and other electronic reconnaissance means.

Description

technical field [0001] The invention and creation belong to the technical field of hydrological water resource measurement, in particular to a low water resistance water gauge based on machine identification. Background technique [0002] General water gauges are used for monitoring surface water. It is made of metal or non-metallic materials, with scales on it, the accuracy is generally in centimeters (the minimum scale is 1cm), and the water conservancy is generally 1 meter as a section, with pure red and blue as a piece, which is easy to read. A water gauge is generally a device for measuring water surface elevation at a designated location in a river, river, lake or other body of water. When encountering extreme weather, or due to wars in the water gauge measurement area, the surveyors cannot reach the observation point and read the data. At present, ultrasonic and other automatic water level measuring instruments usually need to rely on power, integrated circuits and ...
