摘要： The present disclosure provides a method, an apparatus and a vehicle for trailer angle measurement, applied in a semi-trailer including a tractor and a trailer. At least one LiDAR is provided on each of two sides of a rear part of the tractor. A reflector with a reflective surface is fixedly provided at a front part of the trailer, and the reflective surface faces the LiDARs. The method includes: controlling the LiDARs to emit laser light, such that the reflective surface of the reflector reflects the laser light; controlling each of the LiDARs to receive a corresponding laser point cloud reflected by the reflector; and calculating a trailer angle based on the corresponding laser point clouds. The method and apparatus can increase the range of trailer angle measurement, such that the trailer angle can be measured even if the trailer angle is relatively large.

摘要： A measuring arm is made up of a pair of main links pivotally connected together at one end, and a pair of shorter end links each pivotally connected at one end to an other end of each main link. A distance sensor is able to be attached to an end of one of the end links, and to either of a pair of support bases mounted at different locations on a relatively fixed structure. The measuring arm is particularly useful in inspecting contoured surfaces of seals installed on an automobile to aid in detecting defective seals.

摘要： In some implementations, a dot projector optic may include a collimating lens; a fisheye lens; and a dot aberration correction element disposed between the collimating lens and the fisheye lens. An input to the fisheye lens, from the dot aberration correction element, may be associated with a first field of view angle. An output from the fisheye lens may be associated with a second field of view angle that is larger than the first field of view angle.

摘要： Provided are a tire shape measurement device and a method. In a measurement mode in which air is injected into an inside of a tire mounted on a holding portion to inflate the tire and the tire and a non-contact sensor are relatively moved in a tire circumferential direction to detect a shape of a predetermined site of the tire over an entire circumference in the tire circumferential direction by the sensor, a detection unit of the sensor is covered with a cover portion is released. When the air is exhausted from the inside of the tire to an outside and the tire is deflated to remove the tire from the holding portion after the detection of the shape of the tire, a standby mode M1 in which the detection unit is covered with the cover portion is set.
