Problems solved by technology
Research on the rhythm and cycle of beacon light based on fiber optic spectrometer has fewer restrictions, but the intensity and color detection of beacon light can only be carried out in the laboratory. Due to volume, weight and other reasons, optical indicators are difficult to carry out laboratory testing, which is not conducive to grasping its lighting performance in time

The invention discloses a portable beacon light field detection system based on an image processing technology, and the system is characterized by comprising a camera, a lens, a polarizing film, a laser range finder, a holder, an embedded processor, a touch screen display, a power supply module, a serial port, and a network port; the beacon light detection system is based on the photoelectric detection technology and integrates the function of on-site detection of the light rhythm, the period, the color and the light intensity of the beacon light, so that on-site detection of indexes such as the light rhythm, the period, the color and the light intensity of the beacon light during navigation mark inspection and navigation mark efficiency acceptance is realized, and the system is of great significance in carrying out fine management on the navigation mark light and improving navigation aiding efficiency of the navigation mark.
Description
technical field [0001] The present invention relates to the field of photoelectric detection technology, in particular to a portable on-site detection system for navigation lights based on image processing technology, and an on-site detection system for light indicators such as rhythm, cycle, color and light intensity of navigation lights based on photoelectric detection technology. Portable detection system. Background technique [0002] Navigation marks are very important signs to help guide ships to navigate, locate and mark obstructions and express warnings. At present, the detection of navigation marks mainly relies on laboratory testing, and the staff need to go to the sea regularly to bring the navigation lights back to the shore laboratory for testing, so as to determine whether there is a problem with the navigation lights. Due to the large size of the navigation light itself and the cumbersome disassembly process, there are problems such as high requirements for t...
