INFORMATION PROCESSING DEVICE, INFORMATION PROCESSING METHOD, AND PROGRAM

WIPO Patent Application WO/2023/176646

A1

The present invention reduces a data amount. This information processing device (100) comprises a peak detection unit (110), a reflected light peak determination unit (120), and an output unit (130). The peak detection unit (110) detects at least one peak of a detection frequency in a time-of-flight histogram that represents, in the number of times and ranks of a detection frequency, a time-of-flight distribution of reflected light detected in a pixel array unit of a two-dimensional shape, the reflected light being emitted from a light source and reflected by a subject. The reflected light peak determination unit (120) determines whether reflected light peaks corresponding to the reflected light are included in peaks. The output unit (130) outputs, as distance measurement data, the reflected light peaks on the basis of the determination that one reflected light peak is included in the peaks, and outputs, as distance measurement data, a candidate area of the time-of-flight histogram including candidates of the reflected light peaks on the basis of the determination that a plurality of reflected light peaks are included in the peaks or the determination that no reflected light peak is included in the peaks.
