The embodiment of the disclosure provides a three-dimensional scanning detection method, which is applied to the technical field of three-dimensional scanning and comprises the steps of setting at least one reference area on a preset model, and definitely defining key positions which need preferential attention of a user and ensure the integrity of scanning data. And then guiding a user to scan based on the set reference area, and generating verification information in real time in the scanning process, wherein the verification information displays the achievement condition of the accumulation degree of the scanning data in the reference area relative to the saturation threshold of the scanning data in a visual mode, so that the user is directly informed of whether the scanning data of each reference area is complete or not, and the user is guided to timely perform complementary scanning on the incomplete area. According to the scheme, the verification of the integrity of the scanning data is advanced from the traditional post detection link to the real-time scanning process, so that a user can actively ensure the scanning integrity of the key area based on visual feedback, and the detection misjudgment and reworking risks caused by missing scanning or incomplete data are fundamentally avoided.
