Problems solved by technology

While this method is effective in identifying clear paths, it requires a lot of processing power to identify and separate different objects in the visual image, for example, distinguishing between a tree along the side of the road and a pedestrian walking towards the side of the road
This approach may be slow or inefficient for complex situations, or may require cumbersome and expensive equipment to provide the required processing capacity

Embodiment Construction

[0033] Referring now to the drawings, wherein the views are for illustration of certain exemplary embodiments only and not for limitation of said embodiments, figure 1 An exemplary arrangement of a camera 110 according to the invention located in front of the vehicle 100 and directed towards the ground in front of the vehicle 100 is shown. The camera 110 is in communication with a processing module 120 that contains logic to process input from the camera 110 . The vehicle 100 may also be equipped with a radar imaging system 130 which, when present, also communicates with the processing module 120 . Those of ordinary skill in the art should understand that, in addition to or instead of using the camera 110 and the radar imaging system 130, the vehicle 100 can use a variety of methods to identify road conditions, including GPS information, information from and the vehicle. Information from other vehicles communicated by 100, historical data about specific road surfaces, biomet...

Abstract

The invention relates to a no-texture clear path detection based on pixel. A method for detecting a clear path of travel for a vehicle by analysing a plurality of imaged generated by a camera on the vehicle, comprises: monitoring the images, wherein each image comprises pixels; analysing the images using the no-texture processing project, comprising: filtering the image to separate the image partcapable of showing the clear surface capable of estimating the latent road surface with other image part capable of not showing the latent road surface. The clear path is determined based on the clear surface and the clear path is used for operating the vehicle.

Description

[0001] Cross References to Related Applications [0002] This application is a continuation-in-part of US Application No. 12 / 108,581 filed April 24, 2008, which is hereby incorporated by reference. technical field [0003] The invention relates to automatic or semi-automatic control of motor vehicles. Background technique [0004] The statements in this section merely provide background information related to the present disclosure and may not constitute prior art. [0005] Autonomous and semi-autonomous driving systems use inputs about the road and other driving conditions to automatically control the throttle and steering. Accurate estimation and identification of the clear path on which a motor vehicle is desired to operate is critical to successfully replacing the human mind with a vehicle-operated control mechanism. [0006] Road conditions can be complex. Under normal operation of the vehicle, the human operator makes hundreds of observations per minute and adjusts...
