Problems solved by technology
[0007] The object of the present invention is to propose a kind of light fan stereo camera and a kind of stereo measurement method and technology, to solve the following technical problems (not limited to): Compared with the horizontal angle of view, resolution, image efficiency, high-definition image quality and image standard playback format, the image obtained by the dual camera still has a large gap; the second is that all the images output by the traditional panoramic camera are cut and spliced Afterwards, there is a seamless stitching effect with continuous and natural transition, but there is no information about the position and direction of the original image in the image; the third is that the traditional image measurement technology cannot directly obtain the surface area, volume and surface features of the concerned object.

Embodiment Construction
[0155] The detailed description of the present invention shows an example of the embodiment of the present invention, and corresponds to the contents and specific matters in the claims and the specification. The present invention is not limited to the embodiment, and can be embodied in various embodiments without departing from the gist of the present invention. The illustrated cases in all the schematic diagrams are examples of the multiple implementable technical solutions described above.
[0156] Picture 1-1 and Figure 1-2 What is shown is a schematic diagram of the imaging principle of the first light fan stereo camera. Picture 1-1 In the top view, the distance between the centerlines of the two optical lens modules is t. A slanted plate lens 2 is arranged in the lens group 1 . The inclined plate lens 2 translates the image from the front lens in the lens group 1 along the horizontal direction toward the centerline of the light fan stereo camera, and enters the lig...

The invention discloses a light fan stereo camera and a stereo measurement method. The two images collected by a light fan stereo camera are respectively compressed by two light fans along the horizontal direction and then imaged on the same image sensor. The same horizontal viewing angle, resolution, image efficiency and standard playback formats with half the pixels. The stereoscopic image output by a light fan panoramic stereo camera still maintains the information of the original position and direction when the image is collected after being positioned and cut. Natural and seamless stitching effect, but also has the original position and orientation of the stereoscopic image. A stereoscopic measurement method measures the distance of a camera of the concerned object in real time through the stereoscopic image of the concerned object, and focuses on the distance between the objects, the area, the volume and the geometric features on the surface of the concerned object. The invention can be applied to endoscope, stereo camera, panoramic stereo camera, stereo measurement and other stereo image application fields.
Description
technical field [0001] The invention relates to a stereo camera with double lenses and a single image sensor, a light fan, a left and right format of the light fan, a stereo measurement method, a panoramic stereo camera, and a panoramic stereo image cutting and splicing method. Background technique [0002] Two mainstream dual-lens single-image sensor stereoscopic imaging technologies; the first one is that two independent optical lens modules project two independent images with different viewing angles into one image through two imaging circles. Imaging on the left and right halves of the sensor. The second is that two independent images with different viewing angles collected by two independent optical lens modules are re-imaged by a lens group and then projected on an image sensor through an imaging circle for imaging. The left and right images in a left and right format image obtained by the above two imaging circle imaging technologies have the problems of small horizo...
