Embodiment Construction

[0033] exist figure 1A flowchart of the method is shown in the form of a block diagram in . The method starts with the detection 10 of a first camera image, wherein the first camera image is updated at a predetermined detection rate. Then, in step 11, the second camera image is detected. The first and second camera images have a predetermined resolution. Furthermore, the detection 10 of the first camera image and the detection 11 of the second camera image each take place at a predetermined detection rate, wherein the first camera image and the second camera image are each detected, for example, by means of a camera and have a predetermined distance from one another. time offset. The inspections 10 and 11 take place, for example, at 60 camera images per second, the first and second camera images each having at least one XGA resolution, ie each inspected camera image includes at least 1024×768 pixels. Advantageously, the detected first and second camera images each have a f...

Abstract

A method for continuously determining mutually corresponding image points between a first camera image and a second camera image, having the steps of capturing (10) the first camera image (101); capturing (11) the second camera image (102); ascertaining (40) at least one first signature matrix element (203) of a first signature matrix (201) on the basis of the first camera image (101); assigning (60) first coordinates to an ascertained signature value of the first signature matrix element (203) in a signature value position table (300); ascertaining (70) at least one signature value of a second signature matrix element (203) having second coordinates of a second signature matrix (202) on the basis of the second camera image (102); and determining (80) at least one element (503) of a correspondence matrix (500, 501, 502) on the basis of the signature value position table (300), the cyclically ascertained signature value of the second signature matrix element (203) and the second coordinates of this second signature matrix element (203), wherein at least one concatenation matrix element (403) of a concatenation matrix (400) is ascertained (50) on the basis of the first signature matrix (201) and the signature value position table (300), and the element (503) of the correspondence matrix (500, 501, 502) is additionally determined (80) on the basis of the ascertained concatenationmatrix (400), the first camera image (101) and the second camera image (102).

Description

technical field [0001] The invention relates to a method for continuously determining mutually corresponding image points between a first camera image and a second camera image. The present invention also relates to a system-on-a-chip (SoC, System-on-a-chip) for performing the method and a camera system with the SoC. The invention also relates to a control device for carrying out the method. The invention also relates to a vehicle with the camera system or the control device. Background technique [0002] In order to guide the vehicle partially autonomously or autonomously, critical driving situations of the vehicle (eg collision risk) should be recognized at least within a time span of less than approximately 0.2 seconds. This time span corresponds to the average human reaction time. Even more advantageous is a reaction time faster than a human reaction, for example a reaction time of 0.1 seconds. In other words, for autonomous or partially autonomous driving, a recogni...
