Definitions

  • This invention concerns a method and system for inspection, maintenance or repair of a vehicle, especially a motor vehicle or at least one part of a vehicle, wherein geometrical data of the vehicle or of at least one part of a vehicle are determined.
  • wheels of motor vehicles may be aligned on an alignment rack using a computer-aided, three-dimensional (3D) machine vision alignment apparatus.
  • 3D three-dimensional
  • one or more cameras of the alignment apparatus view targets attached to the wheels of the vehicle.
  • the cameras form images of the targets, and a computer in the alignment apparatus analyzes the images of the targets to determine wheel position.
  • the computer guides an operator in properly adjusting the wheels to accomplish precise alignment, based on calculations obtained from processing of the image data.
  • Cameras used in the known imaging systems have typically been limited to CCD type cameras capable of capturing a static image of either a target or tire/wheel assembly. Multiple images are taken at different rotations and inclinations of the wheel assembly to provide sufficient data to allow determination of needed alignment data calculated from the image data. In other systems, multiple cameras located at different known locations with respect to each other capture simultaneous images of the target or wheel assembly and using stereoscopic algorithms, to determine the three-dimensional location of the captured object. Single camera systems do not directly enable the estimation of 3D position except for restricted special cases. For example, if the geometry of the object being imaged is known ahead of time or if the camera is moved a known amount with respect to the object, a single image can enable 3D position estimation.
  • Stereo camera systems do not have perfectly overlapping fields of view. Objects that are visible in one camera may not be visible in other cameras that comprise the stereo sys- tern, and if so their depth cannot be estimated. This problem is more significant for objects at closer ranges.
  • Stereo camera systems tend to be much bulkier and more obtrusive than an equivalent number of cameras arranged in a non-stereo manner. This is significant for areas where space is at a premium (on a lift, for example).
  • stereo camera systems require that the same 3D scene points be matched in each of the images that comprise the stereo system. This image matching task is known as the "correspondence problem" and is often a significant obstacle despite advances in algorithms.
  • the problem to be solved by the invention is to provide a method and a system for inspection, maintenance or repair of vehicles, especially motor vehicles or at least one part of the vehicle in which the determination of the spatial position of a vehicle, especially of a motor vehicle or of one or more parts of the vehicle is enabled by using a simplified imaging system.
  • the simplified imaging system enables the capture of multiple images of the vehicle, especially of a motor vehicle or of one or more parts of the vehicle simultaneously from a light field imaging system and enables determination of distance and angle measurements needed to support the parameter calculation for determining the spatial position of the vehicle and of one or more parts of it.
  • the used light field imaging system is designed to procedure a light field image of the vehicle or of at least one part of the vehicle or of a target attached to the vehicle or to the at least one part of the vehicle.
  • Light sensitive elements are positioned in predetermined locations and designated to determine distinct incident angles of light coming from the vehicle or from the target attached to the vehicle or to the at least one part of the vehicle.
  • Processing means, especially digital processing means are operatively connected to the light sensitive elements to determine from the output data of the light sensitive elements the spatial location of the vehicle or of the at least one part of the vehicle.
  • a preferred embodiment of the invention comprises a light field (i.e. plenoptic) camera which comprises a microlens array located between the camera image sensor (light sensitive sensor) and the camera main lens.
  • the microlens array facilitates the capture of light ray direction in addition to the basic image information available form a single lens camera. By recording this additional light direction parameter in one single image capture, plenoptic cameras can store information of a 3D scene comparable to taking many shots at the same time from different points of view. Depth to different points of interest within the plenoptic camera field of view can be estimated using a combination of the light ray direction and image information collected.
  • the known imaging systems concern the improvement of the imaging quality of the plenoptic camera, whereas the invention uses the plenoptic camera to achieve information about the geometrical properties and characteristics of the vehicle or of at least one part of the vehicle and its spatial position.
  • the plenoptic camera used for the invention is preferably designed such that light passing via each microlens to the light sensitive sensor does not overlay light passed via adjacent microlens.
  • the function of the plenoptic camera significantly reduces the difficulty of the "correspondence problem", the task of matching landmark points across multiple cameras in a stereoscopic imaging system.
  • Useable plenoptic cameras are designed as described in the before mentioned state of art or as described in EP 2 244 484 B1.
  • Another usable embodiment of the light field imaging system includes an angle-sensitive pixel device provided with light-sensitive detectors disposed at predetermined positions and sensitive to both the intensity and the incident angle of incident light from the vehicle or from at least one part of the vehicle.
  • Processing means are adapted to determine from the output data of the detectors the spatial location of the vehicle or of the at least one part of the vehicle and are operatively connected to the light-sensitive detectors.
  • Such a light field image device is known from WO 2010/044943 A2 and comprises a pixel-scale sensor that uses the Talbot effect to detect the local intensity and incident angle of light.
  • the sensor comprises two local diffraction gratings stacked above a photo- diode. When illuminated by a plane wave, the upper grating generates a self-image at the half Talbot depth. The second grating, placed at this depth, blocks or passes light depending upon incident angle.
  • Several such structures, tuned to different incident angles, are sufficient to extract local incident angle and intensity. Furthermore, arrays of such structures are sufficient to localize light sources in three dimensions.
  • the determined position or geometrical data can be used to perform, especially to control maintenance services on the captured vehicle or on the at least one part of the vehicle in a vehicle service station, especially in service or maintenance equipments, like tire changers, wheel balancers, wheel alignment systems, vehicle testing stands, for instance break test stands and suspension test stands, vehicle body measuring system, especially in equipments for the repair of damaged vehicles and vehicle body structures.
