System and method for vehicle radar inspection
The present disclosure provides a system and method for a vehicle radar inspection. A system for inspecting an assembled state of a radar sensor mounted in a vehicle may include a center portion configured to align the vehicle to a reference inspection position; a mobile terminal configured to connect with an external source of communication; a scan portion configured to photograph the radar sensor at a plurality of scan positions using a terahertz wave; and a server configured to match a plurality of scan images photographed by the scan portion, to detect a three-dimensional coordinate of the radar sensor, to transmit a sensor correction value through the mobile terminal, wherein the sensor correction value is determined based on an assembly tolerance that compares with a design plan of the vehicle, and to correct a sensor angle value of the radar sensor.

DISTANCE ESTIMATION USING MULTI-CAMERA DEVICE
A method and apparatus for measuring a distance to an object, be a device (100) having at least two cameras (104, 106), is described. One or more first images including the object are acquired by a first camera of the device and one or more first reference images are acquired by a second camera of the device, while the device is in a first position. One or more second images including the object and one or more second reference images are acquired by cameras of the device, while the device is in a second position, different from the first position. Based on the first and second reference images, information on the displacement of at least one camera of the device between the first and second position are determined. The distance from the device to the object is calculated based on the first and second images including e object and the determined information on the displacement of the at least one camera.

3D CAMERA SYSTEM WITH ROLLING-SHUTTER IMAGE SENSOR
The system comprises an array of addressable light sources, which is configured for an activation of the light sources individually or in groups, an image sensor comprising pixels, which are configured for the detection of a predefined light pattern, and a rolling shutter of the image sensor. The array of addressable light sources is configured for a consecutive activation of the light sources according to the predefined light pattern or part of the predefined light pattern, and the rolling shutter is configured to expose areas of the image sensor in accordance with the activation of the light sources, so that the pixels in an exposed area are illuminated and the pixels that are outside the exposed area are shielded from illumination.

Measurement device and method for operating the same
In a measurement device, a controller causes an imaging unit to generate a plurality of first pictures based on a first image and a plurality of second pictures based on a second image. The controller determines whether or not there is blurring on the basis of at least two of the plurality of first pictures. The controller determines whether or not there is blurring on the basis of at least two of the plurality of second pictures. The controller causes a measurement unit to perform measurement when the controller determines that there is no blurring in first picture blurring determination and second picture blurring determination.

Determining stereo distance information using imaging devices integrated into propeller blades
A propeller provided on an aerial vehicle may include a digital camera or other imaging device embedded into a surface of one of the blades of the propeller. The digital camera may capture images while the propeller is rotating at an operational speed. Images captured by the digital camera may be processed to recognize one or more objects therein, and to determine ranges to such objects by stereo triangulation techniques. Using such ranges, a depth map or other model of the surface features in an environment in which the aerial vehicle is operating may be defined and stored or used for any purpose. A propeller may include digital cameras or other imaging devices embedded into two or more blades, and may also use such images to determine ranges to objects by stereo triangulation techniques.
