Testing method for a camera system, a control unit of the camera system, the camera system, and a vehicle having this camera system

A testing method for a camera system having a control unit and at least one camera, the method comprising the following steps:

• immediately after loading of an operating system of the control unit, performing the following steps:
• generating transmittable image data as a function of at least one source image loaded from an electronic camera memory of the camera;
• transmitting the generated image data from the camera to the control unit;
• generating an intermediate image as a function of the image data received by the control unit;
• ascertaining a processed image as a function of the generated intermediate image;
• ascertaining a first check sum as a function of image information of at least two image pixels of the processed image, the image information being allocated to an image pixel in each case, the image information being at least one of:
• a gray scale value, a brightness, or a descriptive measure for the environment of the image pixel;
• ascertaining a second check sum as a function of the image information of at least two image pixels of at least one reference image;
• comparing the processed image to the reference image, the reference image being loaded from a memory of the control unit, the comparing the processed image to the reference image being as a function of the first check sum and/or the second check sum;
• and
• generating an error signal in the event of a deviation between the processed image and the reference image.

A control unit for a camera system, the control unit being configured to:

• after loading of an operating system of the control unit:
• receive image data from a camera of the camera system using a receiving unit, the image data representing a source image loaded from a camera memory of the camera;
• generate an intermediate image as a function of the received image data;
• ascertain a processed image as a function of the generated intermediate image;
• ascertain a first check sum as a function of image information of at least two image pixels of the processed image;
• ascertaining a second check sum as a function of the image information of at least two image pixels of at least one reference image;
• comparing the processed image to the reference image as a function of the first check sum and the second check sum;
• and
• generate an error signal in the event of a deviation between the processed image and the reference image;
• and
• upon detecting an error represented in the error signal, prevent control of a vehicle by a control signal of the control unit, the control signal being a function of an acquired camera image of the camera.

A camera system, comprising:

• at least one camera;
• and
• a control unit configured to:
• after loading of an operating system of the control unit:
• receive image data from the camera using a receiving unit, the image data representing a source image loaded from a camera memory of the camera;
• generate an intermediate image as a function of the received image data;
• ascertain a processed image as a function of the generated intermediate image;
• ascertain a first check sum as a function of image information of at least two image pixels of the processed image;
• ascertain a second check sum as a function of the image information of at least two image pixels of at least one reference image;
• compare the processed image to the reference image as a function of the first check sum and the second check sum;
• and
• generate an error signal in the event of a deviation between a processed image and a reference image;
• and
• upon detecting an error represented in the error signal, prevent control of a vehicle by a control signal of the control unit, the control signal being a function of an acquired camera image of the camera.

A vehicle, comprising:

• a camera system including:
• at least one camera;
• and
• a control unit configured to:
• after loading of an operating system of the control unit:
• receive image data from the camera using a receiving unit, the image data representing a source image loaded from a camera memory of the camera;
• generate an intermediate image as a function of the received image data;
• ascertain a processed image as a function of the generated intermediate image;
• ascertain a first check sum as a function of image information of at least two image pixels of the processed image;
• ascertain a second check sum as a function of the image information of at least two image pixels of at least one reference image;
• compare the processed image to the reference image as a function of the first check sum and the second check sum;
• and
• generate an error signal in the event of a deviation between a processed image and a reference image;
• and
• upon detecting an error represented in the error signal, prevent control of a vehicle by a control signal of the control unit, the control signal being a function of an acquired camera image of the camera.
