Three-dimensional scanning method, three-dimensional scanning system and electronic device

The invention relates to a three-dimensional scanning method, a three-dimensional scanning system and an electronic device, and the three-dimensional scanning method comprises the steps: obtaining the three-dimensional scanning data of a scanned object, and the information of a target feature object on an object placement surface where the scanned object is placed; wherein the target feature object carries preset feature information; detecting whether a scanning device obtains the target feature object information based on the preset feature information, and determining a scanning background plane of the scanned object according to a plane where the target feature object is located when it is detected that the scanning device obtains the target feature object information; and generating a three-dimensional scanning result according to the three-dimensional scanning data and the scanning background plane. According to the three-dimensional scanning method, the problem of low three-dimensional scanning efficien
