The present invention discloses a translation evaluation based optimized spectrum image data fusion method, and belongs to the technical field of hyper spectrum image data fusion. The method of the present invention includes the steps: firstly classifying pixel vectors of a data matrix to obtain a class matrix; using a dimensionality reduction and projection matrix with changed principal components of the class matrix to project the data matrix for obtaining a dimensionality reduction data matrix; then assigning the dimensionality reduction data matrix to black and white, red and green, and yellow and blue channels to a coloring matching space for conversion into an sRGB color space to obtain color component data of the R, G, and B channels; comprehensively evaluating serial digital images to obtain an optimal translation amount of each channel through translation mapping of the color component data; and finally using three optimal translation amounts to respectively translate and map the color component data of each channel to obtain a fusion result image. An optimal translation amount fusion method is utilized to obtain a pseudo-color fusion image of high luminance, increases the contrast and color distinction degree of the image, and facilitates rapid identification of a target by human eyes from a complex background.

A vehicle-mounted oxygen supply device is characterized in that: the vehicle-mounted oxygen supply device is composed of a gas generator, an air bag, and an air guiding device, and the gas generator is composed of a container, a medicament, a water storage device, a switch, and a one-way valve Composition, the air guiding device is composed of a one-way valve, a catheter, and a breathing switch. When the vehicle falls into the water, the gas supply switch in the gas generator is turned on, and the internal reaction occurs to generate oxygen. The gas enters the airbag through the one-way valve, and the occupants of the vehicle can inhale oxygen through the breathing port, and at the same time, the exhaled gas passes through the one-way valve through the breathing port. And the guide of the catheter enters the gas generator, the carbon dioxide in the exhaled gas in the gas generator is absorbed by the medicine inside the generator, and the remaining oxygen enters the airbag and can be used again; when the occupants are trapped in the car, the device Oxygen can be provided to ensure that it will not drown. When the occupants of the vehicle can escape from the vehicle that fell into the water, the airbag can be used as a lifebuoy to provide sufficient buoyancy for the occupants.

The invention discloses a water supply device for breeding insects. The water supply device for breeding the insects comprises a water storage bottle, a water storage body and a tray, wherein the bottom of the water storage bottle is long and thin, and a round of water outlet holes are formed in the bottom of the water storage bottle, water in the water storage bottle can outflow from the water outlet holes, the water storage body is in a discoid shape, holes are formed in the middle of the water storage body, the edge of the tray is a circular protrusion, the middle of the tray is provided with a small circular protrusion, the size of the water storage body can enable the water storage body to be placed between the two circular protrusions of the tray exactly, the middle portion small circular protrusion of the tray can be inserted into the bottom of the water storage bottle exactly, water inlet holes are formed in the wall of the middle portion small circular protrusion of the tray, and when the bottom of the water storage bottle is inserted into the middle portion small circular protrusion of the tray, the water outlet holes is one-to-one correspondence to the water inlet holes. The water supply device for breeding the insects has the advantages that the insects can not be drowned when the insects take the water, and the device can replenish the water automatically.
