Abstract
A camera is provided that has an image sensor having a plurality of pixel elements for recording image data of an object stream moved in a direction of movement relative to the camera and having objects of a height, and a control and evaluation unit that is configured to determine the height of a respective object with reference to the image data. The image sensor here is an event-based image sensor and the control and evaluation unit is configured to detect a measurement series of points in time at which pixel elements adjacent in the direction of movement consecutively register an event to determine a speed of an object image of the object on the image sensor from said measurement series and from this the height.
