Problems solved by technology

However, in practical applications, it is found that unless there is a precise angle measurement device, the user is not sensitive to the angle, and it is difficult to accurately determine the angle; and when the target object is at the microscopic level, its size is difficult to accurately determine, so that the solution cannot be used on tiny objects. 3D acquisition modeling used in

Abstract

The invention provides acquisition equipment for a tiny target object. The acquisition equipment comprises an image acquisition device, a micro-motion device and an objective table. The micro-motion device comprises a rotary disc and a swing disc, spacers are arranged between the rotary disc and the swing disc, and the spacers rotate along with the rotary disc so as to drive the swing disc to swing near a reference plane. The image acquisition device is arranged on the swing disc. A structure suitable for acquisition around a tiny object is provided for the first time, and the problem of rotating out of view is avoided.

Description

technical field [0001] The invention relates to the technical field of shape measurement, in particular to the technical field of 3D shape measurement of tiny objects. Background technique [0002] At present, when studying cells and microorganisms, traditional microscopes can no longer meet the current needs of stereoscopic observation and measurement because they can only observe plane conditions. However, in current 3D microscopic imaging equipment, confocal imaging is commonly used to form images at different depths, thereby synthesizing 3D images. However, this method usually requires the active emission of laser light or fluorescent light, which may affect living organisms and lead to inaccurate observations. At the same time, due to the layer-by-layer imaging at different depths, the 3D imaging speed is very slow, which is not suitable for living organisms. There is also a way of using lens arrays to split light for multi-focus imaging, but the resolution of this wa...
