The present invention belongs to the field of machine vision system technologies, and discloses a target unit of a machine vision system, a target assembly and a machine vision system, the target unit including a protective plate, a light absorbing layer and a light reflecting layer. The protective plate includes a connection surface. The light reflecting layer is connected to the light absorbing layer, one of the light absorbing layer and the light reflecting layer includes a preset pattern and is connected to the protective plate through the connection surface, and a surface that is of the other of the light absorbing layer and the light reflecting layer and that faces away from the protective plate is an outer surface of the target unit. In the target unit in the embodiments of the present invention, the protective plate can provide functions such as mechanical support, flatness and water resistance and scratch resistance, and a substrate in the prior art can be omitted, so that the weight of the target unit in this embodiment is reduced, and the thickness of a product is reduced, enabling that it is possible to make a thinner product. In addition, a product assembly process is simplified, and product costs are reduced.

Target unit of machine vision system, target assembly and machine vision system

A vehicle detection system includes a support, machine vision modules, a failure sensor, and a controller. Each machine vision module includes image acquisition devices each including s an image acquisition sensor for obtaining related parameters of hardware to be detected of a vehicle. The failure sensor is used for acquiring position change information of the image acquisition sensor and outputting a motion parameter signal comprising the position change information. The controller is used for determining, according to the motion parameter signal, whether the position of the image acquisition sensor needs to be calibrated. In the using process of the vehicle detection system, the controller can determine in real time whether the position of the image acquisition sensor needs to be calibrated, so as to avoid a miscorrection caused by detecting and correcting the vehicle without precalibration after the measurement and calculation precision of the vehicle detection system is reduced.

Vehicle wheels alignment system using image acquisition sensor and vehicle wheels alignment method

A three-dimensional target, a wheel positioning system, and a wheel positioning method are provided. The three-dimensional target includes a base body. The base body is provided with at least three target surfaces which are all in different planes. Each of the at least three target surfaces is provided with target elements. Each of the at least three target surfaces is used for wheel positioning. Two of the at least three target surfaces form a group of calculation units, and the spatial position relationship between the target elements of at least two groups of calculation units is used for determining the position of a wheel. By using two target surfaces as a group, the at least three target surfaces can be configured into multiple groups, and calibration is performed according to the multiple target surfaces; thus, the accuracy of calibration calculation is improved.
