Summary: | To provide an image recognition device capable of reducing power, a calculation amount, a memory occupation amount, and a bus band occupation amount and maintaining high recognition accuracy.SOLUTION: An image recognition device includes: a plurality of signal processing modules that are obtained by connecting a plurality of image sensors having mutually different functions and perform signal processing on the basis of image signals output from the connected image sensors and including an object within an imaging field of view, each signal processing module being capable of controlling power source supply; a recognition processing unit that selectively performs recognition processing on the object according to the output signal of one signal processing module and recognition processing on the object according to the presence of fusion with the output signal of each of the plurality of signal processing modules; and a control unit that supplies a power source to at least one of the signal processing modules to cause the recognition processing unit to perform the recognition processing on the object according to the absence of fusion, determines reliability of the recognition processing result, and executes power source supply control of another signal processing module on the basis of the determination result.SELECTED DRAWING: Figure 1
【課題】電力、計算量、メモリ占有量、バス帯域占有量を削減でき、しかも高い認識精度を維持できる画像認識装置を提供する。【解決手段】画像認識装置は、互いに機能が異なる複数の画像センサを接続し、接続した画像センサから出力され撮像視野内の対象物を含む画像信号に基づいて信号処理を行い、それぞれ電源供給の制御が可能な複数の信号処理モジュールと、1つの信号処理モジュールの出力信号による対象物の認識処理、複数の信号処理モジュールそれぞれの出力信号とのフュージョン有りによる対象物の認識処理を選択的に実行する認識処理部と、少なくとも1つの信号処理モジュールに電源を供給して、認識処理部にフュージョン無しによる対象物の認識処理を実行させ、認識処理結果の信頼度を判定し、判定結果に基づいて、他の信号処理モジュールの電源供給制御を実行する制御部とを備える。【選択図】図1 |
