1. A method for three-dimensional reconstruction of a target object, comprising the following steps:
calculating and acquiring a visual angle boundary of the target object;
acquiring image information of the target object under multiple visual angles in the visual angle boundary, the image information including initial image information and/or fused image information;
finishing three-dimensional reconstruction of the target object according to the acquired image information;
the calculating and acquiring comprising:
acquiring an image of the target object displayed under each of the multiple visual angles;
for each visual angle:
calculating a central position of the target object in the image of the target object displayed under the visual angle; and
calculating a maximum boundary radius by taking the central position as a circle center such that the target object under the visual angle is completely contained in a circle formed by the maximum boundary radius; and
acquiring the visual angle boundary of the target object based on comparison or combination of multiple maximum boundary radii.
