Abstract: The present disclosure provides a method, a computing device and a storage medium. This method includes: collecting a first image having a first bounding box of a target object and a second image having a second bounding box of the target object; calculating a reference scale proportion between two bounding boxes; generating a plurality of scale proportions associated with the reference scale proportion; scaling the second bounding box according to each scale proportion to obtain a third bounding box for extracting a first image block from the first image; extracting a second image block from the second image according to the second bounding box; and performing similarity calculation on the first image block and the second image block corresponding to each scale proportion to screen out at least one scale proportion so as to calculate a prediction value of the collision time with the target object.

Abstract: The present disclosure discloses a method for measuring two-dimensional distribution of an industrial irradiation dose based on sprouting lag time of spores, and provides a film for measuring distribution of an industrial irradiation dose. The method includes the following steps: (1) manufacturing the film: spreading a layer of spore suspension flat on a plane of a carrier, and evaporating a suspension solvent to fix a layer of spore pixel surface on the plane of the carrier; covering the carrier with a glass lid to form a sprouting cavity to cover the spore pixel surface within the sprouting cavity; and providing the glass lid with a filling hole configured to add a sprouting agent; (2) obtaining a calibration curve; and (3) measuring the irradiation dose.

Abstract: Provided are a photoelectric outer cover component for a vehicle and a method for manufacturing the same, which relate to the technical field of photoelectric hybrid vehicles. The outer cover component is formed by laminating and bonding a skin, a solar cell module, a front film and so on. The outer cover component is molded as a whole to fit with the molding of other components of a frame, and the outer cover component is thin in thickness, small in weight and high in reliability.

Abstract: The disclosure provides a solar cell module, a method for preparing the solar cell module, and a vehicle having the solar cell module. The solar cell module comprises an upper encapsulation layer having a predefined curved surface shape, a solar cell pack, an adhesive film, and at least one lower encapsulation back plate. A number of the lower encapsulation back plate is determined according to a radius of curvature of the curved surface shape; and the solar cell pack is placed between the upper encapsulation layer and the at least one lower encapsulation back plate through the adhesive film according to the curved surface shape, and a placement area of the at least one lower encapsulation back plate is not greater than a surface area of the upper encapsulation layer. Therefore, the solar cell module can be placed on the curved surface having a small radius of curvature.
