Control system for an autonomous garden tool, method and apparatus

A method for generating an image for further image processing in an autonomous garden tool that is equipped with a camera for capturing images, the method comprising the following steps:

• controlling camera settings such that the camera can apply a change of camera settings;
• capturing a sequence of images with different camera settings;
• analyzing images of the sequence of images;
• determining, based on the analyzed images, a time on which the change of camera settings is applied by the camera;
• determining, based on said time, two images out of the sequence of images captured by the camera on the basis of different, respective camera settings by analyzing the images of the sequence of images;
• generating a HDR image on the basis of the two consecutive images using the HDR image for implementing a function of the autonomous garden toot
• analyzing the HDR image;
• and
• using the HDR image for automatically implementing a function of the autonomous garden tool.

A control system for an autonomous garden tool that is equipped with at least one camera and at least one motor, wherein the control system comprises:

• a camera control module for controlling camera settings such that the camera can apply a change of camera settings;
• an image generation module configured to i) analyze images of a sequence of images, ii) determine, based on the analyzed images, a time on which the change of camera settings is applied by the camera, iii) determine, based on said time, two consecutive images in the sequence of images captured by the camera on the basis of different, respective camera settings, and iv) generate a HDR image on the basis of these two consecutive images in a HDR mode;
• and
• an image analyzer configured to analyze the HDR image transferred from the image generator,
• the control system being configured to use the HDR image for automatically implementing a function of the autonomous garden tool.
