    摘要: An endoscope stereo imaging device includes an endoscope lens assembly and an imaging module. The imaging module includes first, second and third lens assemblies, a beam splitter, first and second image sensors and a micro lens array. A light beam from the endoscope lens assembly is transmitted to the beam splitter after passing through the first lens assembly and is split into first and second portions of the light beam. The first portion light beam is transmitted to the first image sensor via the second lens assembly and forms a two-dimensional image. The second portion light beam is transmitted to the second image sensor via the third lens assembly and the micro lens array sequentially and forms a first three-dimensional image.

    摘要: A method for evaluating skin tissue includes: obtaining a tomographic image of skin; performing a quantization process for quantizing brightness values of the tomographic image of skin to generate a quantized image; performing a binarization process on the brightness value of each image point in the quantized image according to a first threshold interval to generate a first filtered image; performing the binarization process on the brightness value of each image point in the quantized image according to a second threshold interval to generate a second filtered image; obtaining a first estimated tissue boundary according to the distribution of the bright spots in the first filtered image; obtaining a second estimated tissue boundary according to the distribution of the bright spots in the second filtered image; estimating a thickness of skin tissue according to a difference between the first and second estimated tissue boundaries.

    摘要: An illumination apparatus includes an outer tube, an inner tube, and a light source. The outer tube has a reflecting inner wall. The inner tube is disposed in the outer tube and coaxial with the outer tube. The inner tube has a reflecting outer wall. A ring-shaped light channel is formed between the outer tube and the inner tube. The ring-shaped light channel has a light entrance and a light exit corresponding to two ends of the outer tube respectively. A segment of the inner tube protrudes from the light exit. The light source is disposed at the light entrance. A light beam emitted from the light source enters the ring-shaped light channel through the light entrance, is reflected multiple times by the reflecting inner wall of the outer tube and the reflecting outer wall of the inner tube, and travels out of the illumination apparatus through the light exit.
