[0086] The first embodiment of the present invention proposes an image acquisition and processing device, which is used to acquire and stitch multiple partial images of an object to be photographed. Figure 4 Shown is the image acquisition and processing device of the first embodiment of the present invention, the image acquisition and processing device may include the following components:

[0087] An imaging camera 10 , a reference body 20 , a positioning camera 30 and a processing unit 40 .

[0088] The imaging camera 10 may be a photographing device including a camera, an image sensor, a shutter and other elements, and is used to photograph the object 100 to obtain multiple partial images of the object 100 to be photographed. It should be noted that the aforementioned imaging camera 10 may generally refer to any image acquisition device composed of an image sensor, lens, light source, fixed connection structure and other auxiliary imaging modules, and is not limited to a c...

[0111] The second embodiment of the present invention provides an image acquisition and processing device. In this embodiment, only the difference between this embodiment and the first embodiment will be described.

[0112] In this embodiment, the image acquisition and processing device further includes a driving device 70 for controlling the synchronous movement of the imaging camera 10 and the positioning camera 30, or for controlling the photographed object 100 and the reference Synchronous movement of body 20.

[0113] In one embodiment, the imaging camera 10 and the positioning camera 30 do not move each other under the fixing of the fixing device 60, but the first fixing structure 60 can be driven by the driving device 70 to drive the imaging camera 10 and the positioning camera 30 to perform the aforementioned six steps. degrees of freedom of movement. For example, if the imaging camera 10 and the positioning camera 30 are located on both sides of the fixing device (s...

[0130] The third embodiment of the present invention proposes an image acquisition and processing method, including the following steps:

[0131] S301. Receive multiple partial images of the object to be photographed by the imaging camera and multiple positioning images of the reference body captured by the positioning camera, wherein the positioning images of the reference body include positioning marks, and the multiple partial images and multiple positioning images The shooting positions correspond to each other;

[0132] S302. Using the positioning marks to determine a splicing method for the multiple positioning images;

[0133] S303. Using the splicing method for positioning images, determine a splicing method for multiple partial images of the object to be photographed by the imaging camera, and use the splicing method to splice the multiple partial images of the object.

[0134] In a preferred embodiment, the step of determining the splicing method of the multiple pos...

Abstract

An image acquisition and processing device and method, used for collecting and splicing multiple partial images of an object to be photographed, the device includes: an imaging camera, for capturing multiple partial images of the object to be photographed; A reference body; a positioning camera, fixed relative to the imaging camera, for photographing the reference body, and acquiring a positioning image including at least part of the positioning marks; a synchronization trigger unit, for controlling the synchronization of the imaging camera and the positioning camera Shooting; a processing unit configured to receive a partial image taken by the imaging camera and an image of the positioning mark taken by the positioning camera, and use a plurality of positioning images to determine a plurality of shooting pose information of the imaging camera, to Stitching multiple partial images captured by the imaging camera. The invention realizes the positioning problem during image splicing with a simple structure.

Description

technical field [0001] The invention relates to the field of image acquisition, in particular to an image acquisition and processing device and an image acquisition and processing method. Background technique [0002] There is a demand for large-scale high-resolution imaging in applications such as machine vision and industrial inspection, and the field of view and resolution (including optical resolution and actual size corresponding to a single pixel) captured by the camera are contradictory indicators. For example, in the inspection of wafer surface appearance in the semiconductor manufacturing process, it is necessary to perform high-definition inspection with 1um resolution on wafers with a diameter of 300mm. If a 2K pixel camera is used, the corresponding size of a single picture is only 2mm, which cannot cover the imaging range of 300mm. [0003] A larger range of imaging can be obtained by stitching multiple images taken at different positions, but it is necessary t...
