Embodiment Construction
[0014] Such as figure 1 As shown, the detection device and method 1 of the object outline of the present invention includes a lens (Lens) 11 with a shallow depth of shadow, a repeating movement mechanism 12, an image sensing unit (Image sensor) 13 and a microprocessor 14. . The image sensing unit 13 can be a general digital video camera or an image sensing element in a digital camera; the repeating movement mechanism can be a voice coil motor.
[0015] The repeating movement mechanism 12 combines the lens 11 to drive the lens 11 to move forward and backward repeatedly; the image sensing unit 13 corresponds to the lens 11, and the lens 11 senses multiple images of an object 2; the microprocessor 14 is electrically connected to the repeating movement mechanism 12 and The image sensing unit 13 can detect and record the position information that the repeated movement mechanism 12 drives the lens 11 to repeatedly move back and forth, and detect and record multiple image informatio...

The invention provides an object outline probing method. The probing method comprises steps as follows: respectively sensing multiple images of an object by means of an image sensing unit while repeatedly moving a low depth-of-focus lens among multiple positions, and synchronously recording the information of the multiple positions and the information of the multiple images corresponding to the information of the multiple positions in a one-to-one way; respectively removing unclear areas in the information of the multiple images, so as to obtain the information of clear images; gaining multiple depth-of-focus displacement values based on the displacement between the information of two adjacent positions among the information of the multiple positions; sequentially extending the longitudinal depth of the information of the previous image to reach the corresponding depth-of-focus displacement, and then combining the information of the previous image with the information of the following image, thus combining the information of multiple clear images into the information of a three-dimensional image corresponding to the object outline. With the adoption of the object outline probing method provided by the invention, the information of the three-dimensional outline of the object can be obtained by utilizing a single lens.
Description
technical field [0001] The present invention relates to a detection device and method for object contours, in particular to a device and method for obtaining object contour information by using a camera to capture images of objects. Background technique [0002] A general camera can only capture a plane image of an object, and cannot obtain the three-dimensional contour information of the object by using the plane image. [0003] China Taiwan Patent No. M373507 discloses a stereoscopic panoramic splicing device, including: a staring stereoscopic photography system; image. The stereo vision panorama stitching device includes two cameras, wherein the optical axes of the two cameras intersect at the same point. [0004] China Taiwan Publication Patent No. M364920 discloses a three-dimensional (3D) face recognition device with an infrared light source, including: a stereo camera, a left camera and a right camera, and the left camera is used to obtain a left image, the right T...
