In order to meet the above requirement, in the prior art, two ways of turning the object to be inspected or changing the orientation of the camera are generally adopted to acquire multi-angle images of the object to be inspected.

Taking the chinese patent application with the patent publication number "CN 107388985A" as an example, the patent document discloses a five-axis optical measurement device for three-dimensional surface topography of a revolving body part, which includes a charge coupled device CCD, an optical microscope lens, an annular holder, an embedded annular light source, a rotary clamping device, an XY moving platform, a Z-axis platform, a servo motor, a motor driver, a motion control card, a photoelectric encoder, a computer and an image acquisition card. When the device is used, a revolving body part clamping device and a clamping jaw are fixed, an optical microscope lens is fixed through an annular clamping device, a computer controls an XY platform to move a two-degree-of-freedom rotating clamping device fixed on the XY platform to the lower part of an objective lens, the height of the objective lens, the rotating angle of the rotating clamping device in the XY direction and the illumination intensity of an embedded annular light source are adjusted, so that a measured object appears in the center of a visual field at a proper position and angle, the computer further controls a Z-axis platform to move and sequentially obtains microscopic zooming image sequences under different visual fields, a high-definition two-dimensional fusion image and a high-precision three-dimensional model are generated through the zooming microscopic image sequences, and finally surface parameters and accurate sizes of parts are extracted.

The essence of the five-axis optical measurement device and method for three-dimensional surface topography of a revolving body part disclosed in the above patent application document is that a mode of overturning a detected object and further realizing multi-angle image acquisition is adopted, and in the specific application, because the detected object is clamped and overturned, the mode can not be applied to situations of similar cultural relic image retention, precise part appearance detection, biological form image identification and the like obviously under the condition that the detected object is fragile.

Another conventional method in the prior art is to change the orientation of a camera to obtain multi-angle image data of an object to be inspected, for example, an automatic acquisition system for full-angle photographs of an object modeled by a three-dimensional image is disclosed in chinese patent application publication No. 205505995U, in which a scanning base and an object to be scanned are arranged in the system, the object to be scanned is placed on the scanning base, a fixed support is arranged on the scanning base, a camera array composed of a plurality of cameras is erected on the fixed support, a camera lens of the camera array faces the object to be scanned, and a control module is arranged to control the rotation of the electronic control turntable and the camera array to capture the photographs.

The full-angle automatic photo acquisition system disclosed in the above patent application document is the most common device in the prior art, and acquires multi-angle image data of a photographed object by adopting a method of changing the setting position of a camera and adjusting the shooting angle of the camera for multiple times. It should be pointed out that the structure arrangement of the device and the image acquisition method when applying the device obviously have the problems of slow image acquisition speed, complicated control of the electric control turntable, easy influence of other interference factors such as dust raising and illumination in an open space, and the like when being applied specifically.
