1 EP3608688A1
DISTANCE MEASURING DEVICE
Publication/Patent Number: EP3608688A1 Publication Date: 2020-02-12 Application Number: 18425067.8 Filing Date: 2018-08-09 Inventor: Matsui, Yuki   Nakamuro, Ken   Zappa, Franco   Villa, Federica   Lussana rudi   Assignee: OMRON CORPORATION   Politecnico di Milano   IPC: G01S17/10 Abstract: A distance measuring device (1) includes a light emission portion (3) configured to emit light (8); a light receiving portion (4) configured to receive measurement light (5) that is emitted by the light emission portion (3) and reflected by the measurement object (2), the light receiving portion (4) comprising a plurality of pixels (10) configured to output light reception signals (LR) that depend on the received measurement light (5); a plurality of determination portions (11, 111 - 117) configured to receive the light reception signals (LR) and to determine characteristic values from the received light reception signals (LR), and an evaluation portion (13) that is connected to the plurality of determination portions (11, 111 - 117), the evaluation portion (13) being configured to calculate a distance from the characteristic values determined by the determination portions (11, 111 - 117). Each of the plurality of determination portions (11, 111 - 117) is configured to receive the light reception signals (LR) from a plurality of non-adjacent pixels (10).

DISTANCE MEASURING DEVICE AND DISTANCE MEASURING METHOD
Publication/Patent Number: US2020064451A1 Publication Date: 2020-02-27 Application Number: 16/543,664 Filing Date: 2019-08-19 Inventor: Matsui, Yuki   Nakamuro, Ken   Zappa, Franco   Villa, Federica   Lussana rudi   Assignee: OMRON Corporation   Politecnico di Milano   IPC: G01S7/487 Abstract: A distance measuring device includes a light emission portion for emitting light; a light receiving portion for receiving measurement light that is emitted by the light emission portion and reflected by a measurement object, the light receiving portion comprising a plurality of pixels, each pixel having at least one light receiving portion and outputting a light reception signal that depends on the measurement light incident on the pixel; a discrimination portion for discriminating whether the pixel receives measurement light; a pixel output control portion for selectively outputting the light reception signal of each pixel individually, depending on the determination result of the discrimination portion; and an evaluation portion for receiving the light reception signals output by the pixel output control portion and outputting a distance signal that is indicative of a distance between the measuring device and the measurement object based on these light reception signals.

DISTANCE MEASURING DEVICE
Publication/Patent Number: US2020049822A1 Publication Date: 2020-02-13 Application Number: 16/535,126 Filing Date: 2019-08-08 Inventor: Matsui, Yuki   Nakamuro, Ken   Zappa, Franco   Villa, Federica   Lussana rudi   Assignee: OMRON Corporation   Politecnico di Milano   IPC: G01S17/10 Abstract: A distance measuring device includes a light emission portion configured to emit light; a light receiving portion configured to receive measurement light that is emitted by the light emission portion and reflected by the measurement object, the light receiving portion comprising a plurality of pixels configured to output light reception signals that depend on the received measurement light; a plurality of determination portions configured to receive the light reception signals and to determine characteristic values from the received light reception signals, and an evaluation portion that is connected to the plurality of determination portions, the evaluation portion being configured to calculate a distance from the characteristic values determined by the determination portions. Each of the plurality of determination portions is configured to receive the light reception signals only from a plurality of non-adjacent pixels.
