Title: Correction method of lens distortion
Inventor: MUNEYASU SANEJI
IPC: G06T3/00
Filed: 2011-01-28
Abstract: PROBLEM TO BE SOLVED: To provide a correction method of lens distortion with which a distortion coefficient is estimated in a short time and further with high accuracy and a correction image can be accurately generated.SOLUTION: In a correction method of lens distortion, attention is paid to a character that a relationship between a temporary distortion coefficient and an error is represented by a single-peak target function and a distortion coefficient can be estimated from only one minimal point of the error. A frame line after correction is determined by using the temporary distortion coefficient and a regression line is computed from the frame line after the correction. An error between coordinates of the frame line after the correction and the regression line is computed and a temporary distortion coefficient calculating a minimum error is estimated as a distortion coefficient but magnitude of errors of two temporary distortion coefficients are compared. One of the temporary distortion coefficients is updated to a predetermined error threshold value on the basis of the magnitude and a range of temporary distortion coefficients is narrowed down. Then, a repetitive value is added to a lower limit of the temporary distortion coefficient successively up to an upper limit within the narrowed range, and an error of each added temporary distortion coefficient is calculated. Then, a temporary distortion coefficient calculating a minimum error is estimated as a distortion coefficient.

IPC: B60Q1/14
Filed: 2011-02-02
Abstract: PROBLEM TO BE SOLVED: To provide a technology for reducing the possibility of giving glare to a vehicle forward in a headlamp control device for performing follow-up swivel control.SOLUTION: Target calculation processing executed by an ECU of a headlamp control device is started when detecting a vehicle forward (objective vehicle forward) present in a follow-up swivel range. When the partial high-beam is made to follow the objective vehicle forward, the head lamp turning amount (target swivel) requested for including the objective vehicle forward in a shielding part of the partial high beam is calculated (S402-S404). The operational state of a turning mechanism (motor) when detecting the objective vehicle forward is acquired (S401). Based on the operational state, the control margin indicating a margin to the target swivel is set (S405). The target position of the head lamp is determined by correcting the target swivel by adding the control margin. Thus, the shielding part in the partial high beam can be set to the position of the objective vehicle forward with excellent accuracy.
