摘要： A calibration method for merging object coordinates and a calibration board device using the same are provided. The calibration board device has a plurality of characteristic points and a central reflection element. A center of the central reflection element has a central characteristic point. A distance sensor emits a distance sensing signal to the central reflection element, so as to obtain a central real coordinate. Intrinsic and extrinsic parameters of a camera is used to establish a transformation equation which transforms the central real coordinate into a central image coordinate. Finally, a calibration image of the calibration board device is retrieved, and the central characteristic point is searched, and the central image coordinate is projected on the calibration image whereby the central image coordinate is calibrated to aim at the central characteristic point on the calibration image, thereby generating extrinsic and intrinsic parameter parameters calibrated.

Wherein, the image fetching unit is used to provide an original image, and is connected electrically to the image processing unit, that includes a sharpening filter, a superimposer, and an edge detector. The sharpening filter converts the original image into a sharpened edge image, and the superimposer superimposes the original image to the sharpened edge image, to form an enhanced image. The edge detector fetches the edge of the enhanced image, to obtain a differential edge image. The image processing unit then utilizes selectively the horizontal correction or vertical correction to correct the differential edge image, based on s deviation direction of the differential edge image, to form a corrected image, and provide it to the image output unit to output as required.

摘要： A composite autonomous driving assistant system for making decision and a method of using the same is provided. A longitudinal-controlling autonomous driving assistant device and a lateral-controlling autonomous driving assistant device start to automatically assist in driving a vehicle. Then, a sensing device senses states of the vehicle and an environment and generates one sensing signal. When a controller determines that the collision period is less than a preset collision period and that a deceleration signal of the sensing signal is larger than a preset deceleration, the controller generates a turn-stopping signal. When the controller determines that a turn angle signal of the sensing signal is larger than a preset angle, the controller generates a speed-stopping signal. The system establishes a switching threshold condition when the plurality autonomous driving assistant devices coexist.
