摘要:
A system for calibrating a vision system of an object. For example, a system for calibrating a surround view system of a vehicle. The system may be configured to capture, via a first and second image sensor, a first and second image of a plurality of objects. Upon capturing such information, the system may be configured to determine a position and orientation of the first and the second image sensor relative to the plurality of objects based on the first and the second captured image. Further, the system may be configured to determine a relative position and orientation between the first and the second image sensor based on a result of the determining a position and orientation of the first and the second image sensor. Also, the system may be configured to determine intrinsic and extrinsic parameters of the first and the second image sensor.

A surround view system that can provide a surround view, e.g., a 360° view, from a vehicle by way of cameras positioned at various locations on the vehicle. The cameras can generate image data corresponding to the surround view, and a processing device can process the image data and generate the surround view on a simulated predetermined shape that can be viewed from a display. The simulated predetermined shape can have a flat bottom with a rectangular shape and a rim with a parabolic shape.

Technologies for determining a distance of an object from a vehicle include a computing device to identify an object captured in a fisheye image generated by a fisheye camera of the vehicle. The computing device projects a contour of the identified object on a selected virtual plane that is located outside the vehicle and selected from a predefined set of virtual planes based on a location of the identified object relative to the vehicle. The computing device identifies a bottom of the projected contour on the selected virtual plane and determines an intersection point of an imaginary line with a ground plane coincident with a plane on which the vehicle is positioned. The imaginary line passes through each of the identified bottom of the projected contour and the fisheye camera. The computing device determines a location of the identified object relative to the vehicle based on the determined intersection point and the identified bottom of the projected contour.

A method for flexibly sintering rare earth permanent magnetic alloy comprises: (1) weighing fine powder of rare earth permanent magnetic alloy, loading the fine powder in moulds, and orientedly compacting the fine powder in a press machine and in inert atmosphere to obtain blanks and loading the blanks into charging boxes; (2) after air between the second conveying vehicle and the first isolating valve of the glove box is replaced with inert gas, opening the two isolating valves connected with each other; wherein after a first rolling wheel transmission in the second conveying vehicle transfers the charging tray into the first chamber of the glove box, the two isolating valves are closed, and the second conveying vehicle leaves; (3) after a first conveying vehicle is coupled with a third isolating valve at an end of the second chamber, locking two matching flanges of the two isolating valves tightly; (4) after the first conveying vehicle is coupled with an isolating valve of a sintering furnace, locking matching flanges tightly; and (5) after the sintering furnace is evacuated to a vacuum degree more than 50 Pa, or the sintering furnace is filled with protective gas, processing the blanks with heating and heat preservation according to a preset process curve; wherein the blanks are sintered at a highest temperature of 1200° C. The present invention significantly increases performance of magnets.

Technologies for visualizing moving objects on a bowl-shaped image include a computing device to receive a first fisheye image generated by a first fisheye camera and capturing a first scene and a second fisheye image generated by a second fisheye camera and capturing a second scene overlapping with the first scene at an overlapping region. The computing device identifies a moving object in the overlapping region and modifies a projected overlapping image region to visualize the identified moving object on a virtual bowl-shaped projection surface. The projected overlapping image region is projected on the virtual bowl-shaped projection surface and corresponds with the overlapping region captured in the first and second fisheye images.

摘要:
A system operable to generate a surround view based on image data, where the image data may include image data associated with surroundings of an object, such as a vehicle. The system may also be operable to project the surround view inversely onto a bowl-shaped projection surrounding the object. Further, the system may be operable to generate a virtual user view via a virtual camera position, where the virtual camera position is on a first horizontal ellipse that is about the bowl-shaped projection at a first height. Also, the system is operable to determine a viewing direction from the virtual camera position that points at a location on a second horizontal ellipse that is about the bowl-shaped projection at a second height. The second height may be lower than the first height and the second horizontal ellipse may be smaller than the first horizontal ellipse.
