Problems solved by technology
However, due to space constraints, shooting angle requirements, etc., the camera plane, lens plane and their corresponding focal planes form a certain angle with the object surface. In this case, the object cannot be completely presented within the focal length, resulting in a The area is clear, and the area outside the focus is blurred, as shown in the attached figure 2 shown
[0003] In the field of machine vision, there is currently no suitable method to solve this problem. Usually, it is dealt with by discarding the blurred area, narrowing the field of view or changing the depth of field, which cannot make full use of the resolution of the system and affect the detection of the visual system. Increased efficiency and increased corporate cost burden

Embodiment Construction
[0019] In order to further understand the purpose, structural features and functions of the present invention, the detailed description is as follows in conjunction with the accompanying drawings. It should be understood that the specific embodiments described in this section are only used to explain the present invention, not to limit the present invention.
[0020] Please also refer to Figure 3a , Figure 3a It is a model diagram of the adjusting device of the field of view of the omni-focus camera of the present invention. The device for adjusting the field of view of an all-focus camera of the present invention is composed of a camera 10 , a lens 20 and a light shielding part 30 , and the camera 10 includes a sensor. The light-shielding part 30 is connected to the camera 10 and the lens 20 , and the light-shielding part 30 can be a wire harness tube, black cloth or paper, and the like.
[0021] The camera 10 and the lens 20 are separately installed on a fixed workpiece...

The present invention relates to the field of imaging, and more particularly relates to a device and method for adjusting the field of view of a full-focus camera. The device for adjusting the field of view of a full-focus camera provided by the present invention includes a camera, a lens, and a shading part; the camera and the lens are separately installed on the On a fixed workpiece, and the camera and the lens are connected through a shading part; the workpiece with the fixed lens is a rotatable workpiece, and the lens is rotated at a certain angle relative to the camera so that the object plane, the lens plane and the camera plane intersect in a straight line, which satisfies According to Sham's law, a clear image within the field of view can be obtained.
Description
technical field [0001] The invention relates to the field of imaging, and more particularly relates to an adjustment device and an adjustment method for the field of view of an omni-focus camera. Background technique [0002] In the actual field of view detection system, in most cases, the camera plane, lens plane and their corresponding focus planes of the field of view device are parallel to the plane of the subject, such as Figure 1a As shown, the subject can be clearly displayed in the entire field of view, as shown in the attached Figure 1b shown. However, due to space constraints, shooting angle requirements, etc., the camera plane, lens plane and their corresponding focal planes form a certain angle with the object surface. In this case, the object cannot be completely presented within the focal length, resulting in a The area is clear, and the area outside the focus is blurred, as shown in the attached figure 2 shown. [0003] In the field of machine vision, th...
