Problems solved by technology

[0005] However, this type of verification does not solve the problem of identifying the correct functionality of similar stereo camera devices
For example, it cannot be ruled out that the individual parts of a stereo camera assembly are mechanically detached due to aging

Embodiment Construction

[0019] In a first step, the image sensors of the first monocular camera and the second monocular camera detect images, wherein these images are transmitted as image data to the evaluation device. The first stereoscopic image is analyzed and evaluated from the image data transmitted by the first monocular camera and the second monocular camera, and the second stereoscopic image is analyzed and evaluated from the image data transmitted by the first monocular camera. Subsequently, the image depth information from the first stereoscopic image and the second stereoscopic image is transmitted and checked for consistency. In this way, in particular a verification of the determined image depth information or the determined distance to an object or obstacle takes place.

Abstract

The invention relates to a stereo camera device for a motor vehicle, comprising: a first and a second mono camera, the first and second mono cameras each having at least one optical system and an image sensor for sensing images; an evaluation device, the image sensor of the first mono camera and the image sensor of the second mono camera being connected to the evaluation device in order to transmit image data of the sensed images. The evaluation device is designed: to evaluate a first stereo image from the transmitted image data of the first and the second mono camera, using a stereo camera algorithm; to evaluate a second stereo image from the transmitted image data of the first mono camera, using a mono algorithm; to determine image depth information from each of the first and the secondstereo images; and to check that the image depth information that has been determined from the first and the second stereo images corresponds.

Description

technical field [0001] The invention relates to a stereo camera arrangement according to the preamble of claim 1 . The invention also relates to a motor vehicle with a stereo camera arrangement and a method for operating a stereo camera arrangement. Background technique [0002] Driver assistance systems in vehicles often employ one or more cameras to sense the vehicle's surroundings, for example to identify objects within a wide range in the vehicle's surroundings. These cameras are usually arranged in the vehicle interior behind the windshield and detect through the windshield in the direction of travel. For example, on-board cameras are known for detecting obstacles, lane markings, traffic signs and other road users. [0003] When determining the distance to an object by means of a camera, stereo camera systems are currently preferably used. Stereo camera systems usually consist of two identical camera modules (single cameras), which form separate optical systems, each...
