Zusammenfassung: | To provide a data processing device and the like capable of suppressing erroneous detection.SOLUTION: A processor of a data processing device is configured to acquire detection data including distance measurement data containing physical information relating to a light reception peak in reflected light received in response to emitted light emitted at a distance measurement light emission intensity, which is a light emission intensity in a distance measurement frame, and comparison data containing physical information relating to a light reception peak in reflected light with respect to emitted light emitted at a comparison light emission intensity different from the distance measurement light emission intensity, in a comparison frame different from the distance measurement frame. The processor is configured to exclude, from the distance measurement data, a light reception peak for which a normal condition, in which a difference in intensity ratio between the light emission intensity and light reception intensity at the light reception peak is within an allowable intensity range and a difference in light reception timing at the light reception peak is within an allowable time range between the distance measurement data and the comparison data, is not satisfied.SELECTED DRAWING: Figure 4
【課題】誤検知を抑制可能なデータ処理装置等を提供する。【解決手段】データ処理装置のプロセッサは、測距フレームでの発光強度である測距発光強度にて照射された照射光に対して受光された反射光における受光ピークに関する物理情報を含む測距データと、測距フレームと異なる比較フレームにおいて、測距発光強度と異なる比較発光強度にて照射された照射光に対する反射光における受光ピークに関する物理情報を含む比較データと、を含む検出データを取得することを実行するように構成される。プロセッサは、測距データと比較データとの間において、発光強度と受光ピークでの受光強度との強度比の差が許容強度範囲内且つ受光ピークにおける受光タイミングの差が許容時間範囲内となる正規条件が不成立となる受光ピークを、測距データから除外することを実行するように構成される。【選択図】図4 |
