Method and apparatus for detecting water level based on camera in low illumination environment

摘要

The present invention discloses a method and apparatus for camera based level detection in a low illumination environment. According to an embodiment of the present invention, there is provided a camera-based level detection apparatus in a low-illuminance environment, the apparatus comprising: a processor; And a memory coupled to the processor, wherein the memory amplifies a pixel brightness value of the low-illuminance image input from the camera, and compares color values of different areas of the water depth marker in the image having the amplified pixel brightness value Storing a program instruction executable by the processor for generating a binarized image in accordance with a color value comparison, generating a histogram using the binarized image, and detecting a surface through the generated histogram value, A detection device is provided.;
