New description: [New technical field] ‘This creation is about a stereo scanning system, especially using a strip-image sensor to check whether the surface of the target is abnormal. [Prior Art] Due to the three-dimensional dimensions of the surface, ie X, γ, z dimensions, smoothness • There are considerable quality determinants in many areas, for example, the surface of the target is scanned to see if surface ridges occur. , depression or foreign matter, such as whether the fabric produces hair balls due to friction. In a conventional technique, the laser light is mainly projected onto the surface of the target object, and then the camera is photographed to obtain the entire image, and the image of the horizontal position of the strip light is projected on the surface of the target object to perform the processing of the stereoscopic image. Thereby, a stereoscopic image is generated, and then according to the required conditions, for example, the degree of smoothness of the surface is used to judge whether surface bulging, depression or foreign matter is generated. The disadvantage of using f is that the laser light refers to the surface of (4), which is a narrow-width neon area. Therefore, only the area illuminated by the laser light is processed by the stereo image algorithm. The zoning area, the image data of the ship's domain are all discarded data, which causes the _ rate of the 彡 image to be relatively low, which wastes the resources transmitted by the dragon' while slowing down the processing speed and affecting the efficiency of the overall stereoscopic scanning. Therefore, it is very necessary to use a small image sensor to sense only the image of the area illuminated by the light source, thereby performing the processing of the stereoscopic image algorithm, and then to view, for example, the shirt has an abnormal surface, and the image sense is small 3 M392403 The detector has the advantages of low cost and high resolution to solve the above disadvantages. [New content] The main purpose of this creation is to provide a kind of Lilin (four) system to despise whether the surface stereoscopic size of the target is abnormal, that is, the dimensions of the x-axis, the γ-axis, and the x-axis. The stereo scanning system includes a light source. , optical mirror, image sensor and image inspection device, wherein the light source generates strip-shaped emission light ^ and the strip-shaped emission secret is relative to the target _ water paying, the mirror group and the county _ (10) and the system shift _ _, the optical mirror reflects or guides the strip-shaped emission wire to generate strip-shaped illumination light, and illuminates the surface field of the object to find the strip-shaped light-dragon field, and the image sensor receives the reflected light of the target object 2 strip light projections. The image signal is generated, and the image processing device receives the image money. The _t-based hoarding algorithm generates the image data and slams the raw information according to the required conditions, for example, whether the surface of the object is abnormal.
