  • Three-dimensional reconstruction method and apparatus
    Patent number: 11954832
    Abstract: A method and an apparatus for three-dimensional reconstruction. Images of the reconstruction space captured by N cameras are acquired as N current images in response to an object entering the reconstruction space. Foreground-background differences of all position points in the N current images are obtained according to the N current images and N corresponding initial background images captured by the N cameras when the reconstruction space is empty. Corresponding foreground-background differences of position points in the N current images are fused according to a corresponding relationship between all position points in the N current images and all position points in the reconstruction space, to obtain a foreground-background difference of each position point in the reconstruction space.

  • Chlorination-UV process for decomposition and detoxification of microcystin-LR
    Patent number: 10662100
    Abstract: Provided is an ordered step-wise method for the chlorination and photodestruction of MC-LR contamination of an aqueous liquid such as a potable water supply infested with blue-green algae (cyanobacteria). It has been found possible to usefully chlorinate the water at lower chlorine:MC-LR ratios as compared to known methods and then to irradiate the water with ultraviolet radiation to photolyze the chlorinated MC-LR. The methods incorporate the prechlorination of a cyanotoxin, more advantageously a microcystin, and most advantageously MC-LR, to enhance UV-induced photodegradation of this compound.
