Abstract
An information processing method, device, cloud-based processing device, and computer program product are related to the field of data processing technologies and can cause an increased efficiency in detecting whether a road area contains a depression region. The information processing method includes: acquiring a depth image; processing the depth image to obtain a means-by-row graph, based on which a road area in the depth image is determined; determining a suspected depression region in the road area; and judging over the suspected depression region based on a depression threshold to determine whether the depth image contains a depression region.
Claims18
An information processing method, comprising:
- acquiring a depth image;
- processing the depth image to obtain a means-by-row graph, and determining a road area in the depth image based on the means-by-row graph, wherein the means-by-row graph is obtained by performing average filtering on each row in the depth image;
- determining a suspected depression region in the road area;
- and
- judging over the suspected depression region based on a depression threshold to determine whether the depth image contains a depression region;
- wherein the determining a suspected depression region in the road area comprises:
- calculating row means in the road area;
- establishing a band-stop filter;
- and
- filtering the row means by means of the band-stop filter to thereby obtain the suspected depression region.
An information processing device, comprising:
- a processor;
- and
- a memory storing instructions, which, when executed by the processor, cause the processor to:
- acquire a depth image;
- process the depth image to obtain a means-by-row graph, and then to determine a road area in the depth image based on the means-by-row graph, wherein the means-by-row graph is obtained by performing average filtering on each row in the depth image;
- determine a suspected depression region in the road area;
- and
- judge over the suspected depression region based on the depression threshold to thereby determine whether the depth image contains a depression region;
- wherein the processor is configured to:
- calculate row means in the road area;
- establish a band-stop filter;
- and
- filter the row means by means of the band-stop filter to thereby obtain the suspected depression region.
A non-transitory computer-readable storage medium, having computer program instructions stored thereon, wherein the program instructions, when being executed by a processor, are configured to perform the operations of:
- acquiring a depth image;
- processing the depth image to obtain a means-by-row graph, and determining a road area in the depth image based on the means-by-row graph, wherein the means-by-row graph is obtained by performing average filtering on each row in the depth image;
- determining a suspected depression region in the road area;
- and
- judging over the suspected depression region based on a depression threshold to determine whether the depth image contains a depression region;
- wherein the determining a suspected depression region in the road area comprises:
- calculating row means in the road area;
- establishing a band-stop filter;
- and
- filtering the row means by means of the band-stop filter to thereby obtain the suspected depression region.
