Filed:

Oct 3, 2017

Appl. No.:

15/723293

Inventors:

- Peoria IL, US
Michael Hoffelder - Norwich NY, US
Jeffrey Thomas Stringer - Pittsburgh PA, US

Assignee:

Caterpillar Inc. - Peoria IL

International Classification:

G06T 7/70
G06T 7/80

Abstract:

A method for detecting an object in an environment of a machine is provided. The method includes determining a first height of the object by applying sliding window detection process on an image. The method determines a score indicating a probability that the object detected in the image matches a predefined set of characteristics. The method further includes determining a minimum and a maximum vertical pixel associated with the object. The method includes determining a second height of the object based on a range of the object, the minimum vertical pixel, the maximum vertical pixel, intrinsic and extrinsic calibration parameters of the image capturing device. The method includes comparing the first height with the second height and accordingly, modifying the score regarding the detection of the object in the image based on whether a difference between the first height and the second height meets a predetermined criterion.

Abstract:

A method for testing a perception system is disclosed. The method includes detecting, by a processor, one or more objects in a composite image, the composite image including a first image and at least a portion of a second image. A first set of objects are detected in the first image. Further, the method includes comparing, by the processor, a second set of objects of the one or more objects detected in the portion of the second image with a set of previously detected objects in the portion of the second image. Furthermore, the method includes validating, the performance of the processor in the detection of the first set of objects in the first image by ensuring the second set of objects detected in the at least a portion of a second image matches the set of previously detected objects in the portion of the second image.

Abstract:

A display system for displaying image data of an environment of a machine includes an imaging device. The imaging device generates image data of the environment of the machine. The imaging device stores the image data in an uncompressed form. The imaging device compresses the image data and generates signals indicative of the compressed image data. The display system further includes a display screen communicably coupled to the imaging device. The display screen receives the signals indicative of the compressed image data from the imaging device and displays the compressed image data on the display screen. The imaging device and the display screen identify whether a region of interest exists in the image data. The display screen displays the image data corresponding to the region of interest in the uncompressed form.

Abstract:

A display system for displaying image data of an environment of a machine includes a display screen and a plurality of imaging devices communicably coupled to the display screen. Each of the plurality of imaging devices generates image data of the environment of the machine and has an associated operating parameter. The plurality of imaging devices stores the image data in an uncompressed form. The plurality of imaging devices compresses the image data and generates signals indicative of the compressed image data. The plurality of imaging devices receives the operating parameter associated with at least one another imaging device. The plurality of imaging devices transmits the compressed image data to the display screen based on the associated operating parameter and the received parameter of the at least one another imaging device. The plurality of imaging devices displays an image on the display screen based on the transmitted image data.

International Classification:

G01D 11/24

Abstract:

A piezoelectric sensor assembly is for an electrical system. The electrical system includes a sensor attachment assembly and a number of electrical conductors. The sensor attachment assembly includes a sensor housing and a fastening member for fastening the sensor housing to a corresponding one of the electrical conductors. The piezoelectric sensor assembly includes a processor enclosed by the sensor housing, a piezoelectric sensor element, a wiring assembly electrically connecting the piezoelectric sensor element to the processor, an insulating member coupled to the piezoelectric sensor element and being structured to extend outwardly from the sensor housing to engage the corresponding one of the electrical conductors, and a mounting enclosure structured to mount the piezoelectric sensor element and the insulating member to the sensor housing.
