A method for relocating a mobile vehicle in a simultaneous localization and mapping (SLAM) map is provided. The method can be used in the mobile vehicle moving in an area and includes: using SLAM to establish the SLAM map that corresponds to the area at an initial time point; detecting, by a non-SLAM positioning device, a first position trajectory and a first azimuth trajectory of the mobile vehicle on the SLAM map; detecting, by a SLAM positioning device, a loss probability of the mobile vehicle between a first timestamp and a second timestamp; determining whether a condition is satisfied; and updating the SLAM map to a new SLAM map corresponding to a current time point and updating positioning information of the mobile vehicle in the new SLAM map when the condition is satisfied at the current time point.

Method for relocating a mobile vehicle in a SLAM map and mobile vehicle

A movable device is provided. When the movable device is at a specific position, a range finder detects reflected light in a first field of view to generate first previous data. When the movable device returns to the vicinity of the specific position, the range finder detects reflected light in the first field of view to generate second previous data. The range finder detects reflected light in a second field of view to generate compensation data. The processor unit performs a SLAM operation on the first and second previous data to generate first and second previous maps, respectively. When a probability that the second previous map does not conform to the first previous map is greater than a threshold value, the processor unit performs the SLAM operation on specific data and the compensation data to control the moving path of the movable device.

The disclosure relates to a laser ranging calibration method and a laser range finder including a line laser generation module, an image capturing module and a processing module. The line laser generation module projects a line laser beam to a first direction from a first position. The image capturing module at a second position captures a ranging image in the first direction. When the ranging image includes a calibration target image of a calibration target having a first width, the processing module calculates a measured width of the calibration target according to a position of a line spot image of a laser spot on the calibration target image, obtains a calibration parameter according to the first width and the measured width, performs range finding according to the laser spot shown in the ranging image, and performs a calibration task using a calibration parameter.

Laser ranging calibration method and apparatus using the same

A mobile robot including a light emitting unit, a processing unit, an optical component, an image sensing unit, a control unit and a moving unit is provided. The light emitting unit emits a main beam. The processing unit diverges the main beam to a plurality of sub-beams. The sub-beams constitute a light covering an area. When a portion of the sub-beams irradiate a first object, the first object reflects the sub-beam and a plurality of reflected beams are reflected. The optical component receives the reflected beams and converges it to a first collected beam. The image sensing unit converts the first collected beam into a first detection result. The control unit calculates depth information according to the first detection result. The control unit activates the relevant behavior of the mobile robot according to the depth information and controls the mobile robot through the moving unit.
