Embodiment Construction
[0033] The embodiments described below by referring to the figures are exemplary only for explaining the present invention and should not be construed as limiting the present invention.
[0034] Embodiments of the present invention: as Figure 1-9 As shown, a video acquisition drive device for a computer vision system is disclosed, including: an outer sleeve 1 , an inner sleeve 2 , a drive mechanism 3 and an image acquisition unit 100 . The driving mechanism 3 drives the inner sleeve 2 to rotate and lift on the outer sleeve 1 , and the image acquisition unit 100 is arranged on the inner sleeve 2 and adjusted according to the lifting and lowering of the inner sleeve 2 . In this embodiment, the automatic rotation and lifting method is adopted to control the rotation and expansion of the inner sleeve 2 along the outer sleeve 1 so as to realize the telescopic adjustment of the image acquisition unit 100 more conveniently. In this embodiment, the image acquisition unit 100 is a cam...

The invention discloses a video acquisition driving device of a computer vision system, which comprises an outer sleeve, on which a positioning hole and a guide hole are arranged, and the guide hole is spirally extended along the side wall of the outer sleeve; There are racks. The inner casing is slidably arranged in the positioning hole. The driving mechanism has a driving part, a transmission unit and a gear arranged on the inner side of the inner casing, and the gear is arranged on the outer side of the inner casing and meshes with the rack; the driving part drives the gear to rotate through the transmission unit, and the gear travels along the rack Turn to drive the inner casing to rotate and lift along the helical direction of the guide hole. The image acquisition unit is arranged on the inner casing and adjusted according to the helical lifting and telescopic adjustment of the inner casing. The invention realizes the rotation and lifting of the inner casing and the outer casing through the cooperation of the worm gear to drive the gear along the obliquely arranged helical rack of the outer casing. The structure is simple and the automatic control system is simplified.
Description
technical field [0001] The invention relates to the technical field of image acquisition, in particular to a video acquisition drive device for a computer vision system. Background technique [0002] The computer vision system is a science that studies how to make the machine "see". To put it further, it refers to using cameras and computers instead of human eyes to recognize, track and measure the target, and further do graphics processing to make the computer It is processed into an image that is more suitable for human observation or sent to the instrument for detection. [0003] The computer vision system is one of the most important information obtained by human beings, and the image acquisition unit is an important part of acquiring images in the computer vision system. In order to better adjust the viewing angle of the camera, it is often necessary to adjust the image acquisition unit to meet various image data requirements. The telescoping drive mechanism of the ca...
