Embodiment 1
[0074] refer to Figure 1 to Figure 6 , an underwater video detection device based on omnidirectional vision, including a visual sensor 2 for acquiring video of water areas to be detected, and a microprocessor 6 for image processing, the visual sensor is installed on a lifting mechanism, the The output of the visual sensor 2 is connected to a cable 4 for transmitting underwater video data, the cable 4 is connected to a microprocessor 6, and the microprocessor 6 is connected to a display device, and the microprocessor 6 includes: The data reading module is used to read the video image information transmitted from the visual sensor; the image data file storage module is used to save the video image information in the storage unit by means of a file; the image output module is used to process the processed The image information is output to the display device; the visual sensor 2 is an omnidirectional visual sensor, including a catadioptric mirror 9, a transparent cover 13, and a...
Embodiment 2
[0122] refer to Figure 7 , the rest of the structural features of this embodiment are the same as in Embodiment 1. This embodiment is aimed at underwater video detection in wide water areas, and an underwater lighting lamp is required as a lighting source to ensure that sufficient lighting intensity is provided within the underwater camera range. Therefore, the quality of the underwater video image is guaranteed, and a halogen tungsten lamp can be selected as the light source. Underwater lamps can be composed of stainless steel watertight protective shell, quartz glass watertight light window, leakage protection device and so on. This underwater lamp has the characteristics of long life, reliable operation and stable performance, and can work continuously for a long time. The lamps 19 can be evenly arranged on the periphery between the cone-shaped suppressor and the ODVS upper cover, and the lighting lamps are inclined outward at an angle, so that there is sufficient illumin...
Embodiment 3
[0124] refer to Figure 1 to Figure 6, the rest of the technical solutions are the same as in Embodiment 1. For relatively medium and large underwater cameras, the lifting mechanism can be used to deploy and recover underwater lamps and underwater cameras. depth in order to obtain the best underwater camera field of view. The lifting mechanism is mainly composed of two parts: the underwater part and the winch above the water. The underwater part includes a fixed frame on which an underwater camera and lighting lamps etc. are fixed. The water part includes motors, winches, steering pulleys, etc. The winch is connected on the rotating shaft of the motor, and the steel cable (cable) spans a turning pulley to connect the lifting frame with the winch, so that by turning the winch, the lifting mechanism can be raised and lowered, so that the camera can be positioned at an accurate position.
