20210341615 | METHOD FOR ADJUSTING ELECTROMAGNETIC WAVE DETECTING DEVICE, ELECTROMAGNETIC WAVE DETECTING DEVICE, AND INFORMATION ACQUIRING SYSTEM - An electromagnetic wave detecting device comprises: a first image forming part configured to form an image of electromagnetic waves incident from a detection object; a traveling part including a reference plane and configured to cause electromagnetic waves incident from the first image forming part to the reference plane, to travel in a first direction; and a first detector configured to detect electromagnetic waves having traveled in the first direction. A method for adjusting electromagnetic wave detecting device includes: changing an image formation distance that is a distance between the first image forming part and at least a part of the reference plane; detecting electromagnetic waves traveling in the first direction by the first detector at a changed image formation distance; calculating a determination value based on detection results in the detecting; and adjusting a position of the first image forming part and the traveling part based on the image formation distance when the determination value becomes equal to or higher than the reference value. | 2021-11-04 |
20210341616 | SENSOR FUSION SYSTEM, SYNCHRONIZATION CONTROL APPARATUS, AND SYNCHRONIZATION CONTROL METHOD - The present disclosure relates to a sensor fusion system, a synchronization control apparatus, and a synchronization control method that make it possible to improve a performance in fusion recognition by synchronizing a ranging apparatus and an image-capturing apparatus. | 2021-11-04 |
20210341617 | ACTUATED SPINNING SENSOR - Various embodiments of the present invention are directed towards a system and methods for generating three dimensional (3D) images with increased composite vertical field of view and composite resolution for a spinning three-dimensional sensor, based on actuating the sensor to generate a plurality of sensor axis orientations as a function of rotation of the actuator. The output data from the sensor, such as a spinning LIDAR, is transformable as a function of the actuator angle to generate three dimensional imagery. | 2021-11-04 |
