Abstract

fetched live from OpenAlex

Abstract A three‐dimension camera (Axi‐Vision camera) has been developed that is capable of producing a color image of an object and performing high‐speed mapping of depth information from the camera to the object. With this camera, intensity‐modulated near‐infrared light is irradiated onto the object, and distances to points on the object are computed from the image captured by a camera that has a high‐speed shutter. Since a two‐dimensional scanning mechanism for a laser beam or complex computational processing is unnecessary in this depth mapping system, the distance to the object can be detected at high speed for each pixel of a TV image. For the present paper, a three‐dimension camera adapted to a standard television signal was constructed by development of a high‐output light‐emitting‐diode (LED) array light source capable of high‐speed intensity modulation, an image intensifier capable of high‐speed shutter operation on the nanosecond order, and an optical system. The prototype camera can output a depth image with a resolution of 768 × 493 pixels at a frame rate of 15 Hz, the characteristic depth mapping resolution of the camera is 1.8 cm (when the distance from the camera to the object is 2 m), and the camera can capture an image of a person‐sized object. It was also shown that the depth information thus obtained could be applied to live‐action filming and to CG and other new types of image synthesis. © 2006 Wiley Periodicals, Inc.

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
