Abstract: A novel hollow shaft manufacturing method includes the steps of hollow cold-rolling of seamless steel pipe, cutting, annealing and surface treatment, forming by forging, precision machining, and heat treatment. The present invention uses a new process instead of the traditional process. The forging process using high-strength cold-rolled seamless steel pipes has fewer steps than using bar stock: saving three forging passes, one annealing pass and one surface treatment pass, hence saving about ½ in time and cost, shortening the cycle, reducing costs, reducing energy consumption and reducing the three wastes, increasing the stock utilization rate to about 68%, and reducing the inter-process cost calculated by weight. For the same products, using this process can shorten the production cycle.

Abstract: In the three-dimensional imaging device (three-dimensional image processing device), the depth acquisition unit acquires L depth information and R depth information from a three-dimensional image. The image correction unit adjusts disparities of edge portion areas of a subject based on the L depth information and the R depth information such that the normal positions of the edge portion areas of the subject are farther away.

Abstract: Attempts to achieve a higher resolution and a higher frame rate of a distance image when a distance to an object within a target space is estimated using the TOF method would cause CCD saturation due to shot noise or environment light, and lower distance precision. A distance estimation apparatus illuminates an object with illumination light for distance estimation emitted from a light source that can emit light (electromagnetic wave) having a predetermined illumination frequency, receives reflected light of the illumination light, obtains information about the distance from the apparatus to the object, generates distance image data based on the distance information, extracts edge information of a color image formed using a visible light component obtained in synchronization with the reflected light, and corrects distance information of a target part of the distance image using distance information of a neighboring part of the target part based on the edge information.
