Abstract
Official abstract text for this publication.
An apparatus for generating a test case for an advanced driver assistance system (ADAS). The apparatus includes a communication interface and a processor connected to the communication interface. The processor is configured to generate virtual light detection and ranging (LIDAR) data by performing a process of receiving, via the communication interface, raw data generated using a LIDAR, detecting an object contained in the raw data, and randomly arranging LiDAR data within a boundary of the object.
First claim
Opening claim text (preview).
What is claimed is: 1 . An apparatus for generating a test case for an advanced driver assistance system (ADAS), the apparatus comprising: a communication interface; and a processor connected to the communication interface, wherein the processor is configured to generate virtual light detection and ranging (LIDAR) data by performing a process including: receiving, via the communication interface, raw data generated using a LiDAR, detecting an object contained in the raw data, and randomly arranging LiDAR data within a boundary of the object. 2 . The apparatus of claim 1 , wherein the processor is configured to detect a number of LiDAR points contained within the boundary of the object from the raw data. 3 . The apparatus of claim 2 , wherein the processor is configured to repeatedly perform detecting the number of LiDAR points contained within the boundary of the object while changing the number of LiDAR points within a range that does not reach the detected number of LiDAR points. 4 . The apparatus of claim 2 , wherein the processor is configured to compute a minimum number of LiDAR points necessary to recognize the object. 5 . The apparatus of claim 4 , wherein the processor is configured to repeatedly perform computing the minimum number of LIDAR points while changing the number of LiDAR points within a range that reaches or exceeds the minimum number of LiDAR points. 6 . The apparatus of claim 4 , wherein the processor is configured to compute the minimum number of LiDAR points by repeatedly performing a process of outputting the raw data to an ADAS controller, and checking whether or not the object is recognized by the ADAS controller, while decreasing the number of LiDAR points contained within the boundary of the object. 7 . A method for generating a test case for an advanced driver assistance system (ADAS) using light detection and ranging (LIDAR), the method comprising: receiving, by a processor, raw data generated using a LIDAR; detecting, by the processor, an object contained in the raw data; and generating, by the processor, virtual LiDAR data by performing a process of randomly arranging LiDAR points within a boundary of the object. 8 . The method of claim 7 , further comprising, before generating the virtual LiDAR data, detecting, by the processor, a number of LiDAR points contained within the boundary of the object from the raw data. 9 . The method of claim 8 , wherein generating the virtual LIDAR data includes repeatedly detecting the number of LiDAR points contained within the boundary of the object while changing the number of LiDAR points within a range that does not reach the detected number of LiDAR points. 10 . The method of claim 8 , further comprising, before generating the virtual LiDAR data, computing, by the processor, a minimum number of LiDAR points necessary to recognize the object. 11 . The method of claim 10 , wherein generating the virtual LIDAR data includes repeatedly computing the minimum number of LIDAR points while changing the number of LiDAR points within a range that reaches or exceeds the minimum number of LiDAR points. 12 . The method of claim 10 , wherein computing the minimum number of LiDAR points includes repeatedly performing a process of outputting the raw data to an ADAS controller, and checking whether or not the object is recognized by the ADAS controller, while decrementing a number of LiDAR points contained within the boundary of the object.
