Saliency based beam-forming for object detection
First Claim
1. A method of scanning by a scanning device, comprising:
- performing a first scan over a target region to obtain a plurality of first scan samples at a plurality of locations within the target region;
generating a saliency map of the target region based on signal intensities of the plurality of first scan samples;
determining a salient region within the target region based on the saliency map; and
performing at least one second scan over the salient region to obtain at least one second scan sample in the salient region, wherein the at least one second scan is performed using beamforming to digitally steer a direction of the at least one second scan over the salient region.

Abstract
A scanning device generally produces an image having a uniform resolution throughout a target region. To improve radar scanning/lidar scanning, an efficient scan approach to enable a radar device/lidar device to adoptively perform a scan of a target region based on interested regions and/or an adjustable resolution. The apparatus may be a scanning device for scanning. The apparatus performs a first scan over a target region to obtain a plurality of first scan samples at a plurality of locations within the target region. The apparatus generates a saliency map of the target region based on signal intensities of the plurality of first scan samples. The apparatus determines a salient region within the target region based on the saliency map. The apparatus performs at least one second scan over the salient region to obtain at least one second scan sample in the salient region.
