Abstract

The invention relates to a stereo camera system with at least two image detection sensors which are fixedly connected to a circuit board. The image detection sensors are coplanar and a fixed distance apart.

Claims

1. A stereo camera system with comprising:

a board; and

at least two coplanar image detection sensors connected to the board a predetermined fixed distance apart.

3. The stereo camera system according to claim 1 wherein the image detection sensors are optical semiconductor sensors, CCD image detection sensors and/or CMOS image detection sensors.

4. The stereo camera system according to claim 1 wherein the board is a circuit board.

5. The stereo camera system according to claim 1 wherein each of the image detection sensors has an image sensing area and the distance between the center points of the image sensing areas of the image detection sensors has a value in the range between 80 mm and 30 mm.

6. The stereo camera system according to claim 4 further comprising at least one evaluation unit connected to the board.

7. The stereo camera system according to claim 5 wherein at least one of the image detection sensors and the evaluation unit is connected to the board by a soldered joint, a plug connection and/or a press connection.

9. The stereo camera system according to claim 4 wherein a first marginal line of an image sensing area of a first image detection sensor and a first marginal line of an image sensing area of a second image detection sensor lie on a first straight line and/or a second marginal line of the image sensing area of the first image detection sensor and a second marginal line of the image sensing area of the second image detection sensor lie on a second straight line.

10. The stereo camera system according to claim 7,

characterized in that the marginal lines are each formed by pixel sensing elements of the image sensing areas.

11. The stereo camera system according to claim 5 wherein the evaluation unit executes at least one image processing program for processing the image data generated by the image detection sensors.

12. The stereo camera system according to claim 1 wherein at least one infrared illumination device is connected to the board.

13. The stereo camera system according to claim 1 wherein the stereo camera system generates and/or processes color images and/or black-and-white images.

14. The stereo camera system according to claim 1 wherein at least two optical systems are connected to the board and/or are arranged relative to the board such that one visual representation each of a detection range of the stereo camera system is imaged and/or focused onto one image sensing area each of the image detection sensors.

15. The stereo camera system according to claim 12, characterized in that the respective optical axis of an optical system runs through the center point of the image sensing area of an image detection sensor.

16. The stereo camera system according to claim 13 wherein the image detection sensors are identical and/or in that the optical systems are identical.

17. The stereo camera system according to claim 1 wherein the stereo camera system includes a housing that surrounds the board and the components connected to the board.
