Provided are a CT scanning method and system, an electronic device, and a computer-readable storage medium. The method includes: determining a first coordinate of a mark point of a part to be imaged in a dual-camera coordinate system; converting the first coordinate into a second coordinate of the mark point in a CT coordinate system according to coordinate system transformation parameters; generating first locating information according to the second coordinate to drive a scanning table to move to a first location designated by the first locating information; obtaining projection images of the part to be scanned; determining second locating information and scanning information of the part to be scanned according to the projection images; and driving the scanning table to move to a second location designated by the second locating information according to the second locating information and performing CT scanning according to the scanning information.

The automatic semi-conductor condensate flower watering device consists of a condensate part, a heat radiating part and a soil moisture control part, in which the said condensing part is composed of a semi-conductor cooling block with a refrigerating and heat-conducting base plate and a heat radiating and conducting base plate attached to both of its sides. On the said refrigerating and heat conducting base plate is installed the condensing fins and on the heat radiating and conducting base plate is installed the heat radiating fins. The said heat radiating part includes radiating fins and an outlet channel that is formed by the radiating fins. The gap between the said condensing fins is less or equal to 1.5 mm. On the refrigerating and heat conducting base plate is installed a water wiper. The present flower watering device also includes a soil moisture unit that can impose a precise control over the moisture of the soil at any time and even when the relative humidity of the air is 40%, it still can respond to the changes in the humidity of the atmosphere. Besides, it also has a high efficiency of water collection and can make full use of the water resources contained in the air.
