摘要： A system and method for calibrating a vehicle optical sensor includes positioning the vehicle in a test station having a projection surface in view of the optical sensor, positioning targets on two hubs of the vehicle, and positioning lasers left to right that are mounted on a graduated mounting bar in front of the vehicle. The graduated mounting bar includes gradations indicative of a lateral position of the lasers on the graduated mounting bar. The lasers are configured to obtain a distance to the targets and distances along respective axes and between the lasers. The calibration is performed based on the obtained distances and once the vehicle's position in the test station is known with respect to the test station.

摘要： A projection system and a self-adaptive adjustment method are provided. The projection system includes a projection device, an image capturing device, and a processing device. The projection device sequentially projects sub-pattern arrays of a pattern array to a projection region of a projection surface. The image capturing device sequentially captures the sub-pattern arrays projected on the projection surface to output pattern images. The processing device analyzes the pattern images to obtain pattern coordinates and a pattern order of projected patterns in each pattern image. The processing device determines at least a part of the projected patterns to be effective patterns according to the pattern coordinates and the pattern order, and adjusts the projection device according to the effective patterns. The projection system and the self-adaptive adjustment method provide good projection quality.

摘要： There is provided a highly efficient virtual image projection device in a small size that displays images of high luminance in which an illumination system is reduced in size with no degradation in an effective luminous light beam. A virtual image projection device that shows video to a human eye includes a virtual light source surface (116) that emits a light beam in a predetermined angular distribution, an image forming lens (117) that condenses the light beam from the virtual light source surface (116), and a display (120) that creates video. When the virtual light source surface (116) is disposed at a nearly focal position on the front side of the image forming lens (117), the display (120) is disposed at a nearly focal position on the rear side of the image forming lens.

摘要： A projection system according to an embodiment of the present technology includes an image formation apparatus, a projection lens, a measurement apparatus, a control apparatus, and a measurement assisting apparatus. The image formation apparatus forms image light. The projection lens projects the image light. The measurement apparatus measures the image light. The control apparatus controls the image formation apparatus on the basis of output of the measurement apparatus. The measurement assisting apparatus is disposed between the image formation apparatus and the projection lens and is configured to be capable of selectively switching between a first state to cause the image light to enter the projection lens and a second state to cause the image light to enter the measurement apparatus.

摘要： An object of the present invention is to provide a projection apparatus capable of appropriately performing control relating to a rotation state and/or a movement state of a projection lens. A projection apparatus according to an aspect of the present invention includes a housing; a light source; a control unit; and a projection lens attached to the housing, the projection lens having a holder, a detection unit that detects a rotation state of the holder, an emission optical system, and a locking mechanism unit that brings rotation of the holder into a locked state or an unlocked state. The projection lens is displaceable between a first position at which a rotation state of the holder is a housed state in which the emission optical system faces the housing and a second position at which the emission optical system does not face the housing by rotating the holder. The second position includes an upper position at which the emission optical system faces an upper side in a vertical direction. The control unit turns off the light source when a rotation state of the holder is the first position. The control unit turns on the light source when the rotation state of the holder is at the upper position. When the light source is turned on in the housed state in which the emission optical system faces the housing, the light emitted from the emission optical system hits the housing, and the temperatures of the projection lens and the housing may increase, which may cause an adverse effect. However, when the rotation state is the housed state, the control unit turns off the light source, thereby preventing the adverse effect.
