Abstract
An image processing apparatus includes a photographing device, an image processor and a fault diagnostic device. The photographing device outputs image data. The image processor includes an electronic circuit having recognition algorithms respectively for image recognition of a predetermined recognition target included in the image data. The fault diagnostic device determines that a fault occurs in the image processor, based on a condition that a first recognition result of recognizing test image data including a characteristic pattern also included in the recognition target in case of the image processor receiving the test image data is different from an expected value as a second recognition result of recognizing the test image data in case of one of the recognition algorithms receiving the test image data.
Claims6
An image processing apparatus comprising;
- a photographing device configured to output image data;
- an image processor including an electronic circuit having a neural network provided with a plurality of recognition algorithms respectively for image recognition of a predetermined recognition target included in the image data;
- and
- a fault diagnostic device configured to determine that a fault occurs in the image processor, based on a condition that a recognition accuracy as a first recognition result output from the neural network in case of providing test image data to the image processor is different from an expected value as a second recognition result output from the neural network in case of preliminarily providing the test image data to one of the recognition algorithms,
- wherein the test image data includes a characteristic pattern that is also included in the predetermined recognition target, and
- wherein each of the first recognition result and the second recognition result indicates a result of recognizing the characteristic pattern through the one of the recognition algorithms.
An image processing apparatus comprising:
- a camera configured to output image data;
- an image processor including an electronic circuit having a neural network provided with a plurality of recognition algorithms respectively for image recognition of a predetermined recognition target included in the image data;
- and
- a processor and a memory that stores instructions configured to, when executed by the processor, cause the processor to determine that a fault occurs in the image processor, based on a condition that a recognition accuracy output as a first recognition result from the neural network in case of providing test image data to the image processor is different from an expected value as a second recognition result output from the neural network in case of preliminarily providing the test image data to one of the recognition algorithms,
- wherein the test image data includes a characteristic pattern that is also included in the predetermined recognition target, and
- wherein each of the first recognition result and the second recognition result indicates a result of recognizing the characteristic pattern through the one of the recognition algorithms.
