Latest Patents

Shibata's latest patents include a camera calibration system and a three-dimensional measuring system. The camera calibration system is designed to be robust against noise factors such as variations in environmental lighting and obstructions. It utilizes light-emitting markers, whose on/off states can be controlled, arranged in a matrix on a reference panel where an object is placed. These markers blink in accordance with specific switching patterns synchronized with the continuous imaging of a camera. A three-dimensional measuring instrument determines the time-varying bright-and-dark pattern of a blinking point from the image of each frame, identifying which light-emitting marker corresponds to each point. This identification allows for effective camera calibration and computation of a coordinate transformation parameter.

The three-dimensional measurement sensor patent involves a matrix of light detectors. The outputs of light detectors in the same row are connected to a common signal line. During a horizontal scan period, the output of each light detector is read from left to right. A position detector measures the time from the start of the horizontal scan until the maximum peak of a signal is detected, indicating the distance from the end of the row. A recording processor then records this distance in correspondence with a counter value indicating the projection angle of the slit angle.
