Publication number: 20240078817Abstract: The present disclosure relates to a method and apparatus for generating a lane polyline by using a neural network model. The method according to an embodiment may extract a multi-scale image feature by using a base image obtained from at least one sensor loaded in a vehicle. According to the method, the multi-scale image feature is input to a first neural network model as input data and a BEV feature may be obtained as output data from the first neural network model. Also, according to the method, the BEV feature may be input to a second neural network model as input data and a polyline image with respect to a certain road may be obtained as output data from the second neural network model. In the present disclosure, a lane polyline obtained from the neural network may be utilized in vehicle control without going through an additional treatment process.Type: ApplicationFiled: August 30, 2023Publication date: March 7, 2024Inventors: Seok Woo JUNG, Hee Yeon KWON, Jung Hee KIM, Seong Gyun JEONG

Patent number: 10509385Abstract: Disclosed embodiments include methods of controlling an encoder principle axis speed synchronization for controlling a motor, which may be executed by a microprocessor. In some embodiments, the microprocessor includes latching a count value to a specific memory at an input time of an encoder pulse signal when a control period is commenced and the encoder pulse signal is received, generating an output pulse using the count value latched to the specific memory, and mapping the output pulse to an output during a next control period. In some embodiments, an interval between encoder pulse signals is calculated using a count value at an input time of the encoder pulse signal and an encoder input speed is measured according to the interval therebetween so that an encoder speed may be exactly measured.Type: GrantFiled: July 29, 2016Date of Patent: December 17, 2019Assignee: LSIS CO., LTD.Inventor: Seok-Yeon Kim
